Unit 19: The Internet of Things - TCMT - Caleb Wakeham

Introduction

The Internet of Things, also known as an IoT is made up of things that have identities that are unique to themselves, they are also connected to the internet. Devices that are already existing, computers with network and phones with 4G/5G are already containing their own form of unique identities, they are also connected to the internet through the IoT in the configuration control plus networking through the internet of “things” that are not usually connected to the internet. There are four different services for the IoT, these are productivity, safety/security, efficiency/effectiveness, and experience plus the satisfaction of users.

Starting off with productivity, this a creation of something that has a high quality and speed that is quicker than manual production, an example of productivity is in manufacturing organizations, by allowing the processes in real time to be analyzed, this is done through using historical data to reduce downtime, this is to make sure there is the conformity for the project.

Moving onto safety and security, the process of safety is stopping or protecting something from being damaged or harmed. Security is the procedures placed to protect something and keep it safe, an example of this is, in the home, allowing monitoring of household systems in a remoter manner, these can include intruder alarms plus providing connectivity with any emergency services.

Efficiency is the method of achieving something without wasting any time, money and effort. Effectiveness is measured on how successful the outcome is. An example of this includes enabling the monitoring and explanation of both air and water.

Home Device 1 – Amazon Alexa

Purpose

Amazon Alexa, also known as simply an Alexa, is a multi-functional device that can be controlled by a user. Alexa, originally known as Ivona, was said to be inspired by 2001: A Space Odyssey. In 2013 the device was bought by Amazon; Alexa was then created in 2014.

The Amazon Alexa device helps with productivity as it allows for various tasks to be completed in a quicker fashion, these include setting alarms/timers, creating reminders, allow for music/videos to be played, questions can also be answered, this is done through the Alexa searching the question on the internet, other things can be searched on the internet too, smart devices can also be controlled through the Amazon Alexa too, these are a few of the features that can be done through the Amazon Alexa with there being a lot more features that the user can use the Amazon Alexa to do.

The Amazon Alexa is safe as Amazon have recently introduced a feature where the Amazon Alexa users are protected, the safety is achieved through allowing the user to delete everything said that day, ask the device what was heard and even opting out of voice recording and human reviews, this can allow the user to feel as safe as possible as they will know that no-one is able to hear their conversations. On the account side of the Amazon Alexa, a strong password and two-factor authentication can also be used so the Alexa account can be kept secure, this will prevent hackers or other types of people entering their account.

Amazon Alexa is highly effective as it can be controlled through voice commands, nothing needs to be clicked, typed or any other physical inputs need to be done in order to use the device, so it is extremely useful to be used when searching for ingredients for cooking, ask timers to be set when exercising etc., taking these into account and how the Amazon Alexa helps with productivity, this means the device is highly effective, also looking at the 	sales of the Alexa, as of 2019, the device has been sold over 100 million times, meaning the device has been highly effective for many people.

Looking at the Amazon Echo 2020, the same device as the Alexa, just renamed, most pros include the look of the device being futuristic, better sounding and faster response times, cons include maximum volume not being loud enough, the overall review out of 5 stars, is usually 4.5 stars, so it is safe to say the device is quite liked.

Applications

The main purpose of Alexa is to be used in the home; this is because the features of Alexa are basic so they cannot handle any bigger tasks, some tasks it can handle include voice interaction, playing music/podcasts, playing audiobooks, creating lists/notes, setting alarms, providing weather updates, providing traffic status updates, providing sports updates and other information in real time. Another feature that Alexa is capable of is controlling smart devices within the home, this is done through the home automation system built into Alexa. These features all fall under home tasks, the Alexa cannot be used in any other areas.

Principles

Alexa will collect data when the start-up word is stated, the default start-up word is “Alexa”, once stated, the Alexa will listen to what the person is saying, if they hear a command such as “Alexa, play music”, or “Alexa start a 15-minute timer” the device will do these actions, there are also other actions that the device could perform, such as creating reminders, searching the internet and control the internet, the device is also able to provide unique facts, tell jokes and play games with the person. The collection and analysis of data to trigger an action that results in needs being met is collecting the command from the person, analyzing it will be the device processing the command, the output is then the action being triggered with a need being made.

Alexa is a device that relies on the Internet as without Internet, the device is virtually worthless, this is because the device uses features that only include Internet connections, such as searching the Internet, playing music or podcasts from a streaming service, playing a video that comes from the Internet. With these features, it is clear to see that the Internet connection is required for the intended use of the Alexa, although the device can be used as a speaker, many users would buy the device for its Internet capabilities.

Alexa uses real time data with commands that are inputted by the user. After the command is entered, the data is then analysed, this is so the data can be processed and then finally outputted and give the user their expected need that they have asked the device to deliver. For this data to be processed it must be sent to the cloud server and then delivered, this is how all devices are operated. With this, it is clear to see that the Alexa also has access to the analogue data from the physical world, this is through the voice commands that the device will hear. Unless turned off, the Alexa is always on, however the only way the Alexa will start to listen to audio in the real world is when the wake-word is stated, the original word is “Alexa” however this can be changed.

Characteristics

Some risks that arise with the Amazon Alexa include it always being on, this means it will drain a lot of power if it is connected directly to a power source, even when it is not connected directly to a power source, it will require a lot of batteries in order to keep the device alive. Another risk is that anyone can connect to the device at any time, if the device is on, this is a risk as the device can then be manipulated, such as making an unnecessary phone call to someone, playing music at a high level etc, so it is important the device is only on when it is needed. Another risk is when asking the Alexa to search internet or asking a question it may search internet and bring back false information, so it is important to make sure all information being delivered is correct.

Some ethical issues that may arise with the Amazon Alexa include the device being always on, with this people tend to think the device listens to the user and would send the information from the conversations somewhere, such as third-person parties. however, this is not the case as Alexa has enabled the feature where voice recordings can be disabled and/or deleted. This is to ensure the user that the device is not listening. And sending the information off to people. The Amazon Alexa does in fact listen to the user though, however, data is not sent off, the data being used is so the Alexa can discover what the user will do, what you say, and how it interacts with the device this is so it can make itself helpful in the future.

Some legal considerations for the Alexa include making sure no data is used by third parties, or for Amazon's personal use or even recording and sending off data for Amazon's personal use again. So, with this it was important for Amazon to make sure that the Amazon Alexa is used efficiently and properly without the need to have data being sent to them, as without consent, it is illegal for conversations to be used and shared by someone.

Amazon had started a process which made all their products sustainable. With this they created a website listing how they will keep the devices safe for the environment but still highly efficient. Something methods Amazon had started to combat sustainability was to use recycled materials, avoid using plastic, invest in clean energy plus training in useless items for them to be recycled, the main method they have started to do that relates to the Alexa is the use of recycled items, as it is highly likely that most Alexa’s, use older but still working parts.

The Amazon Alexa has low motility as it is small, with this it can be packed easily and moved at anytime as it is also light and only requires one wire, the one to charge it.

The Alexa is time controlled in two ways; the first way is through its life. It can be set to be on for a certain amount of time, if a time is not set, it will be turned off once the battery has died. The other way is through timers, timers can be set for whatever time, once the timer has finished, a sound will play.

The Alexa uses monitoring through its wake word, the wake word is “Alexa”, once this word is heard, the Alexa will listen to conversations, once the conversation is over the device will deliver the output that has been stated.

Home Device 2 - Smart TV

Purpose

A smart TV is a television the uses an Internet connection, with this it offers a lot of online features. These include apps such as Netflix, Amazon Prime, YouTube and even music streaming services such as Spotify or even Apple Music. Smart TVs are often used for easier access to these internet-based applications as the user will not need to go to a phone, tablet or computer to the applications, this makes these TVs quite helpful for a person or family.

Smart TVs are often safe as they provide limited access to the Internet. So, with this it is quite hard for the user to gain access to a virus or even be hacked. They are also secure as they ensure safety measures such as two-step authentication, security questions or other types of security measures are in place. This is so no one can hack into the user's email address. and use the device for malicious intent.

One of the main benefits of a Smart TV is to access many channels that are only available using an antenna or subscription to a cable/satellite service. Using the Internet, it is quite easy for a user to gain access to applications such as ITV Hub, BBC iPlayer or other types of applications that may not be found without an antenna or a Sky subscription.

As there are a variety of different smart TVs made by different companies it is hard to find an accurate and average star rating for these smart TVs. However, it is important to know that most people are integrating smart TVs into their homes as they are a helpful device for a home as they enable easier access to applications, viewing photos or even playing music.

Applications

Smart TVs are mainly used in the home as their intended uses are for watching tv, playing games, playing music, browsing the internet and even looking through images/videos. With this the area that the device is most useful in is in the home.

In health and wellbeing, Smart TVs are often used to display information about that hospital, display information about diseases or even showcasing website where appointments can be booked, they can also be used to announce to people whose appointment is ready and what room they are in.

In industrial and transportation, smart TVs are often used to display the times and destinations for transportation, for example, the platform number, the arrival time for a train, the departure time for that train and its final destination, it may also show stopping points on the journey too.

In retail and commence the only time TVs are used is when they are being sold, usually when being sold, it will display a video, this is to showcase the video quality the Smart TV is capable of.

Principles

A smart TV will collect data through viewing what the user is watching or listening to, after viewing and listening to what the user is doing, it will then deliver ads based off the data that was being collected. Data is also collected through the microphone function, with this the user can click the button and state their command, some commands include “play YouTube, “play music” to name a few, with these small pieces of data being collected, they are then processed, and an action is shortly followed, this is also an example of real-time data. With the microphone feature, this means the TV has access to analogue data such as audio, however this only when the microphone button is clicked.

Smart TVs rely on an Internet connexion as most of these applications, such as Netflix, ITV Hub and BBC iPlayer will need an Internet connection in order to be used, an Internet connection is also needed to log in to these applications, without the Internet,  this renders the smart TV as useless, it also makes the smart TV pretty much a regular TV as the difference between a smart TV and a regular TV is the Internet based applications.

When plugged in smart TV's are always on however, they are unable to collect any data as they are placed in stand-by mode, stand-by mode is a low power mode for electronic devices, the standby mode is used to save significant amounts of electrical consumption.

Characteristics

A risk of a smart TV could be an application such as Netflix or BBC iPlayer being hacked with this it means that the account could be lost if the user is able to change the email or password, or even both. Another risk is the consumption of power that is Smart TV might use. It is important to always put the TV in standby mode or even turn it off if going a large amount of time without using the device, this ensures that the Smart TV does not use up too much power, the less power used, the better.

Some ethical and privacy considerations that developers and creators of Smart TV's need to follow include, the way data is handled and sent out, for example, If the third-person party data is sent out to is safe, also personalised advertisements need to be as safe as possible, as the company cannot use too personal information as it may go against the general Data Protection Act of 2018.

Using Samsung, a creator of smart TVs. In 2021, they created and presented a presentation on how they will contribute an eco-friendly future using sustainability. Some methods they would follow include solar cell remote controls. This would expect to reduce greenhouse gas emissions by over 14,000 tonnes over the course of seven years due to these two new types of remote controls that they have implemented. They also ensure that they will recycle plastic, Samsung have already been quite sustainable as for the past few years they have recycled materials in rear panels and stands of their Smart TVs and monitors.

The benefits of having a smart TV include smartphone compatibility with smart TVs, making it easy to stream from your mobile device straight to the TV. Smart TVs are also easy to set up with this, they are also easy to use. Also, with Smart TV there is only one remote controller as that one remote controller is able to control the TV as a whole no matter what application they are using, so it removes the need for multiple remote controllers.

Smart TVs have low mobility as they are quite heavy and big, meaning they are hard to move. However, when they are new and still in the box, they're quite easy to move as all wires, remote controls, the TV and other things are in the box.

Smart TVs are time controlled as there is a feature that allows these smart TVs to turn off after a certain amount of time of inactivity, the inactivity time is set by the user. Some smart TVs also have the feature to enable timers.

Smart TVs will monitor and detect events by buttons being pressed or held. Activity is also detected when the microphone button is pressed. A command will also be followed through a speech. The TV will then process and output the command that was requested.

Smart TVs will have a high-power consumption, however, these TVs have features that reduce the amount of power consumed. This is the feature of stand-by mode, in this mode, the device uses as little power as possible while still being “on”.

Industrial/Transportation Device 1 – GPS

Purpose

GPS is used for tracking a location. This GPS could be moved, and the device will still be updated, GPS is often used in smart devices.

GPS is often safe and secure as locating and viewing in the GPS location is often password protected, meaning in order to view the location, the password and even email address, sometimes, will need to be entered.

GPS is efficient and effective as it allows the location to be found and tracked even when there is no Wi-Fi or reception, so this makes it easy and efficient for the device to be tracked. It is often used for vehicles or even when tracking an item, this is so it can be tracked even if there is no communication from the person driving the vehicle.

Due to being created over 50 years ago, it is quite clear to see the device is still helpful to a lot of people as it's still being used to this day.

Applications

In the home, GPS can be used for many things such as smart phones, tablets, baby monitors and even remote controls. The GPS is implemented so these devices can be found easily or any easier fashion.

GPS can be used in health and wellbeing through tracking health items, where they are and how long it will take for them to arrive at their destination.

In industrial GPS can be used to find the location of production robots that are helping create products. In transportation, GPS is used to track the location of transportation vehicles, this is so they could see the vehicle is safe and on route to its destination. It is also used to track items that are being delivered.

Again in retail and commerce, the only time GPS is used is to track the location of an item that is being delivered to that store.

Principles

Data is collected through tracking the coordinates of the GPS. That data is then converted to an address or a location, the data is then sent to the device that is tracking that GPS, this meets the needs of the person tracking the GPS.

GPS often does not need Internet to work. However, in telecommunications, GPS is often used to track the location of that telecommunications device, This is often used to see the distance that that telecommunication device is able to reach.

GPS uses and analyses real time data through collecting the location where that GPS is, the GPS is then converted and then transmitted back to a cloud or the server, this is usually where GPS is tracked by a person.

The only analogue data used for GPS is through GPS receivers, they measure distance between each satellite through the amount of time it takes a radio wave to reach another satellite.

Characteristics

Some risks that arise with GPS include GPS devices usually needing around 7 or 8 signals from satellites to calculate a location to within about 10 metres surrounding the device. With less satellites, the less accurate the location becomes. Another risk is when the battery of the GPS dies, it is unable to be found. However, more recently Apple devices have implemented a feature where after the devices died, it can still be tracked.

Some ethical issues that may arise with GPS include unwanted location tracking from someone you may not even know. So, it is important to purchase GPS devices where it clearly states how the GPS will be used. With this it also means data is being accessed whether the user may or may not want their data to be accessed. So again, it is important to discover and cheque what is being used and how it is being used.

GPS devices are sustainable as they are a fundamental technology as dubbed by a lot of websites. In many areas they help with sustainability. For example, in agriculture, the use of GPS guidance systems on 10% of planted acres in the United States each year would reduce multiple different things such as fuel use by up to 16 million gallons herbicide by two million quarts, an insecticide used by 4,000,000 pounds. In construction, high precision and accurate GPS is used in order to support building of roads, bridges and even other infrastructure projects. Projects that are used in GPS can reduce any wetland impact, reduce any endangered species that could reduce landslide risks, the residential displacement and also, they could minimise Oh yeah. the impact of existing utilities right now. In transportation, GPS is the main focal point of the FAA’s next generation of an air transportation system. Any GPS enabled flight paths can reduce the flying time, the fuel use and any aircraft exhaust emissions. Finally, in municipal services GPS can be used for the real time tracking of any trucks, garbage trucks, buses and snowploughs. This leads to savings in money, fuel and time. In Niles, IL, Department of Public waste use GPS in order to optimise the routine of all snowploughs. This led to a 40% reduction in the use of salt. And 700 plus tonnes of salt saved.

GPS devices are often small, mean and they can be moved very easily due to them being light and small.

Industrial/Transportation Device 2 – Automated Processing Robots

Purpose

These robots are used to decrease the time spent on a project. They also increase the number of products made in that time too. They can remove any human error as everything entered will be the exact same, so the only thing wrong would be the entry from the human.

These robots are often safe and have features that disable the robot when something's close or affecting the robot. However, if the safety measures are not put in place, the robots can be deadly, these automation robots have caused many, many deaths over the years, however, overtime they going getting safer and safer.

The automation robots increase efficiency heavily as they are able to produce more products in a smaller time due to the robot being given code to follow. This code can be followed repeatedly. All human error is also removed as the code will be followed time and time again.

Again, it is quite hard to measure the satisfaction from users. However, due to them being used over and over again and being bettered over the years, it is clear to see they are helpful.

Applications

Automation robots are not yet developed enough for the home. Once they're fully developed, they will likely be introduced into the home. However, this could still take a couple of decades.

In the health industry, automation robots are used to improve the quality and safety of operations. This is to remove human error and make operations a lot safer resulting in a lot fewer deaths.

While primarily used in the industry and transportation industry, automation robots are used to decrease the process of producing products a lot less time consuming. They are also used to remove any chance of human error as all it needs is code to be entered into the system, that code will then be followed repeatedly resulting in the same action and process being repeated, this removes the chance of human error, the time spent on producing is also reduced too.

In the retail industry, again, automation robots are still in development, meaning they are not much use right now, however, in the future they could be a huge necessity for the industry of retail

Principles

For automation robots collecting and analyzing data is done through entering code into the system that is being used for the robot. Firstly, code will be entered into that system, it is then processed and finally an action is outputted resulting in a need being met.

Automation robots will usually rely on existing Internet through the programming language that is being used for an automation robot, meaning an Internet connection, is required usually to access that language. If there is no Internet connection, then the automation robot is usually not able to fulfil the tasks that are being set.

An automation robot will usually analyze and have access to real time data, such as the product, this is needed as they will need to send a signal to the server stating that the product is completed. This will then repeat the in order for more products to be created in the future.

An automation robot will have access and analyze analogue data from the physical world as this will allow them to stop and shut down if something is nearby that may affect the automation that is being produced from the robot, this is also for safety measures as it ensures and lessens the chance of any deaths or dangerous accidents happening, so, this is important feature to be introduced in the programming language to ensure safety.

Characteristics

Risks that come with manufacturing robots is that the line they operate could mess up, so it is important that code is entered beforehand to make sure nothing goes wrong, or anyone goes hurt. Another risk is that if the code entered into the programming language is incorrect, then this will mean every single product being developed by the automation robot will be incorrect. So, it is important for all code to be entered into the programming language to be 100% correct.

A privacy consideration that needs to be considered is that no one can access the programming language unless they must, meaning no hackers or any malicious content could be entered in the program language, meaning that the production may be affected or even halted, so it is important the language to be password protected.

Some legal considerations that need to be considered is that no one gets seriously hurt or even killed when near the automation robot. In order to maintain safety, it is important to introduce a feature where the robot is disabled when activity is done close by. If someone dies or gets seriously hurt from one of these automation robots, then it will result in a lawsuit and even the termination of these automation robots in that company. So, to ensure this does not happen a safety feature is needed.

Sustainability consideration that comes with automation. Robots include less materials being wasted, as if the code is 100% correct when entered it means that no materials will go to waste, it also removes any human error, which also could result in production waste or material waste.

These automation robots are often big, heavy and hard to move, so this means the mobility of these is quite low. Due to these factors.

Automation robots are mostly time controlled as they have a schedule on when they can produce products. They're often turned off after a few hours as this is done to ensure that they do not waste any power as they use a lot of power

The automation robot will monitor and detect events that happen around them. This is done so no injuries are sustained or even deaths happen, this also ensures the high level of safety.

Comparing the Devices

'''

Comparing Purpose'''

All four of the devices increase the productivity as they all are intended to do so, for example, both the Alexa and the smart TV are used to decrease the time taken to play media, the Alexa allows for easy spoken commands to play primarily music and the smart TV can use voice commands to play videos, so despite being different devices, they both have similar uses which both increase productivity. The GPS is different to these home items however still are used for increased productivity, just in a different sense, the device is used to find pinpoint locations of where the tracker is, comparing it to the automation robots they are very different, the automation robot is nothing like the GPS as these are used for creating products in a faster and made exactly the same each time, these robots are also different to the Amazon Alexa and the smart TV, however they all have the same premise of higher productivity.

Alexa, the smart TV, and GPS are safe devices, they have no known safety issues that could harm someone, however the only one that could be dangerous or even deadly are the automation robots, these robots are known to have accidentally caused incidents, so using them is a precaution. On the internal side, all of these could have security issues, starting off with the Alexa and the smart TV, these could be hacked if the email address and password is not secure, easy to guess etc., furthermore additional security such as two-step authentication could be used to reduce the likeliness of hacking being done too. The GPS can also be hacked, in this case the hackers are able to “GPS spoof” this is the action of falsifying the coordinates of where the device is, this can be done just as mentioned before, through unsecure email addresses and passwords. The automation robots would again be dangerous, more than likely dangerous if hacked as the hacker is able to input any code into the program, the robot will then output the code and could cause severe damage, again it is wise to have strong email addresses and passwords, even further security such as two-step authentication if the program permits it.

All the devices increase efficiency and effectiveness, starting off with the Alexa and the smart TV, they are efficient as they allow multiple tasks to be done, such as playing music, media, searching the internet and using voice commands to name a few. GPS is also efficient as it allows for pinpoint location tracking, this could make tracking items/products a lot easier for a company and could even less items are lost. Automation robots can increase efficiency as they allow products to be made quicker, without human error and it also removes the need for a human to be present.

All the devices have satisfied users have they have been continually made since they were first released meaning they have helped people enough to be made.

Comparing Applications

The main industry in which Alexa and the smart TV can be used is in the home, this is because they are designed to satisfy a family, they could be used in health and wellbeing as they could announce to patients whose appointment is next, this could be in a doctor, hospital etc. I think they would not work in the industrial and transportation at all. The only way they could be used in retail and commerce is putting them on display to be sold.

Moving onto the GPS and the automation robots, they do not fit in at the home, health and wellbeing and retail and commerce industries. They are designed primarily for the industrial and transportation industries, the GPS is used to track items whereas automation robots are used for faster creation times, however both fit under the industrial and transportation section.

'''

Comparing Principles'''

All the devices collect and analyse data, starting off with the Alexa the device collects data through voice commands, a command is stated, the device collects it, analyses it, and processes it, this is the same for the voice command on the smart TV. The smart TV also collects data through pressing buttons on a TV remote, once something has been clicked, the TV processes it and an output is done. The GPS collects data through viewing where a person is, the data is analyses and coordinates are outputted. Automation robots collect data through code being inputted into the system, the code is compiled, this does a process and then when the code is run this results in an action being outputted.

The Alexa and smart TV are reliant on internet as they are needed to fulfil the requirements that are set out, these include using Netflix, playing music and more. The GPS usually does not need internet however some may require it to view the GPS’ location, the same goes for automation robot, it depends on whether the programming language requires internet to be used.

Alexa, smart TV’s and GPS use real time data and analogue data. Alexa and the smart TV uses real time data and analogue data through voice commands. GPS uses both real time and analogue data through tracking where the GPS device is located. Automation robots only uses real time data as when a new product is placed in front of it needs to recognise this and reset the code.

Alexa, smart TVs and GPS use always on connectivity, this is so monitor data from the physical world, Alexa does this by fully being on when the wake word is said, smart TVs are fully on when the power button is clicked, GPS is always on so all movements can be tracked.

Comparing Characteristics

Risks are there for all these devices, one risk between the Alexa, smart TV and the GPS is that they are always on. With this it means data may be picked up the device without a person realising, this is an ethical and privacy concern, it could also result in legal concerns also, so it is important to turn off the device to avoid this. A risk that both Alexa and the smart TV is when searching the internet, it may bring false information, so it is important to cross reference the information. The biggest risk with the automation robot is they may malfunction, this could cause serious issues to the surrounding environment, it may even hurt or kill someone.

The only low mobility devices are the Alexa and the GPS, though the smart TV is easy to move only when it is unopened. The automation robots are quite big meaning they are not easy to move.

Alexa, smart TV and the automation robots can be time controlled, meaning they can be on for a certain amount of time before turning off, also the Alexa and smart TV’s can also have timers and alarms too.

Only three of the devices are able to monitor to detect an event, the Alexa does this through stating its wake word, the smart TV does not do this while the GPS does this through movement of the tracking device, finally the automation robot is able to do this when there is change in the product it is creating, this is done for safety reasons and to avoid anyone getting hurt.

The Alexa and smart TV use a little power consumption when in standby mode, however when fully off they use little to no power, so it is important to turn them fully off when not in use for long periods of time.
