Comparison of all 4 devices

Comparisons

Purpose: Comparing all of the devices together, the devices were from different sectors. Amazon Alexa being from a home/entertainment sector, Smart watch being from a health and wellbeing sector, smart payment being industrial and transpiration sector and lastly motion tracking devices being from many sectors that can be considered such as retail and commerce, entertainment as well as industrial and transportation. When comparing all the different devices, the purpose for all of the device is different and specific to their sector in their own way meaning that a smart watch will have a health and wellbeing benefit as it measures the heartbeat of the user whereas an Amazon Alexa won’t be able to measure the user's heartbeat therefore it cannot be considered for the health and wellbeing sector. In the same sense, a smart payment system or a motion tracking device will also not be able to bring a health or wellbeing benefit due to their own purpose and difference in the job and purpose that specific system has. When comparing the devices, both Amazon Alexa and Motion tracking devices provide the same purpose which is solving existing problems, both of these devices have different execution however they solve existing problems. Amazon Alexa solves problems by being able to buy anything online without having to actually go to that place and the motion tracking allows companies to capture human movement more realistically without the need to draw the motion. The motion tracking devices also have additional similarities with the smart payment devices as both IoT devices increase efficiency and effectiveness, in the same way with the other devices, these devices have a specific execution in their purpose however they help the same cause of problems. The smart watch is the one device that is the odd one out as it doesn’t have any similarities, rather it’s a lot different as it doesn’t boost efficiency or effectiveness however it boosts productivity as it allows the user to check emails, messages and take phone calls with one press without the need to carry a mobile phone or a laptop. Amazon Alexa can also be considered the odd one out under one aspect of the device which is safety and security as Amazon Alexa allows the user to join with other devices/applications in order to help secure the house.

Applications: When comparing all of the devices together and their application, I have found out that all of the devices have different applications depending on their sector, due to all of the devices I have chosen being from 4 different sectors all of the applications are complete opposite of each other as an example, Amazon Alexa would usually be situated at home acting as a real time virtual assistant meaning that it couldn’t be used in the retail and commerce district as a smart payment method, some goes for a smart payment device, It wouldn’t be able to function correctly in a home environment as a virtual assistant. When comparing all of the devices, all of them have different applications however some of the have similar applications, one of these examples would be Amazon Alexa, Smart Payment devices and motion tracking devices, all of which have an application in same district however they have their own execution and their own purpose as an example the Alexa would be able to play music in a store whereas the smart payment device would be able to take care of the effortless payments and the motion tracking devices would be able to control automated doors, these would open if a person is close to them. As mentioned above again, the smart watch can be considered the odd one out as the watch has a perfect application in health and wellbeing as it is able to track different data of the body, in addition the motion tracking devices are also the odd ones out as they can be applied in entertainment whereas the other devices cannot.

Principles: When comparing the principles of all of the devices, I have found similarities and differences with each of the devices presented above. In comparison, all of the devices have the same application when collecting data meaning that all of the devices contain a sensor of some kind within the system/device that collect data and processes that data or compared data collected to a data base in order to apply the correct trigger and or correct action as an example, Amazon Alexa will be able to identify the voice of the user due to a sensor, that data will be processed and a correct trigger will occur in the same sense a motion sensor device will be able to identify the motion of a person, process that data and trigger an action. The devices have the same process of data collection however one thing that sets the devices apart is their data collection as well as the data they are based around meaning that a motion device will collect different type of data and using that data it will have a different trigger to a smart watch that would measure the heartbeat compared to a motion tracking device that will collect data about the motion displaying a different type of action e.g., showing the movement on a TV screen compared to a smart watch giving out a beep if the heartbeat has reached a certain point.

Characteristics: When comparing characteristics of all of the devices, I have found out that the characteristics of certain Internet of Things devices have a lot of similarities as well as differences. When comparing the 4 devices, I have found that Amazon Alexa, Smart Watch and Smart Payment Devices have the same technical characteristic which is Time Controlled, this is because all 3 devices work real time, both Alexa and Smart Watch can have a alarm set at a specific time whereas the smart payment device can’t set an alarm however due to payment transactions occurring it will require to draw money from the bank account in real time comparing, in addition the smart payment device have an additional technical characteristic which others don’t have, smart payment devices are low mobility due to them being in a specific district in a specific region such as check out tills. When comparing the motion tracking devices, this device does not have those technical characteristics, the only characteristic it has is location specific triggers. All 4 of the devices outlined above have one huge similarity between them all, all the devices have benefits. All the devices have different benefits however they still benefit the user that is using them. From these 4 devices, Amazon Alexa could be considered the odd one out as it has legal considerations that the user needs to be aware of as it is important to understand that Amazon Alexa is listening to the environment for a voice in order to react instantly.

When comparing characteristics of the 4 devices, I have found out that there are multiple similarities as well as differences. The smart watch and smart payment both have the same characteristic, which is legal consideration, this is because they are required to collect data that can be considered sensitive, in addition, smart payment also has ethical and privacy consideration due to certain views of certain people that think that using credit cards and smart payments is not ethical, comparing to other devices, no other devices listed have the same characteristics. The other characteristic involved is the risk of hacking that Amazon Alexa may encounter due to the security of the device allowing the intruder to access certain things in the home if it's connected to the Alexa lastly, in comparison to all devices, all of the devices have some kind of benefit to the user which can be considered as a characteristic. When it comes to technical characteristics the devices have their similarities and their differences, as an example, the Amazon Alexa and Motion Tracking would be similar as both of them have low mobility as the Alexa needs constant power and the Motion Tracking devices only work at a certain range before they are ineffective, in addition the smart watch and smart payment devices would be different to these 2 devices however would hold similarities between them as they are both low power consumption devices allowing them to work for extensive periods of time without the need to charge them or replace the battery.
