I created sketches to bring the ideas to life and help me to focus on how I could implement and develop them.
I chose the wrist mounted "watch" phone idea to develop as I believed it had the most potential to be a useful product but then incorporated the other features into it in order to make it more advanced than the current generation of smart phones.
The phone is roughly 5cm by 4cm, which is significantly smaller than current models. This allows the option for it to be attached to a wrist strap in order for it to be work like a watch. This gives the user easy access as they no longer have to take the phone out of their pocket, also freeing up pockets for other items. The phone is held onto the strap by a system of locking pins which can only be unlocked by the user. This is achieved via a fingerprint recognition system which identifies the owner of the phone. This adds to the security of the device as it makes theft more difficult.
The screen projection feature is my solution to the need to pick up and unlock a phone to see notifications. Instead, the use of voice command allows the contents of the screen to be projected onto a nearby wall in mere seconds. This makes it much less effort to check text messages and emails. A benefit of this is the option to change the size of the projection. A large image will allow videos to be watched comfortably without requiring a phone with a large screen. Once the image size is set, in real time the angle of the projection will be adjusted so that the image remains the same size, even if the distance between the device and the wall changes. Likewise if the angle of the device from the wall changes, the projection will adjust so that the image remains parallel with the correct aspect ratio. The projector is located on the top side of the device so that the function still works when the phone is worn on the wrist.
Access to memory cards will be performed wirelessly, meaning that they do not need to be inserted into the device, or be anywhere closer than 10m from it. This means that they can be left in bags or pockets and so do not get lost as easily. Access to the data will be authorised by the fingerprint recognition system, meaning that someone whos fingerprints do not match the ones assigned to the memory card will not be granted access. The use of cloud network storage systems will allow the device to work seamlessly with a home PC, meaning that file access and transfer can occur from anywhere with an internet connection.
The device will be able to work with home appliances such as cookers, washing machines, fridges and heating sytems in order to manage their operation away from home. For example, if the user wanted to turn the heating on before they got home in order to warm the house up, they could set the time and duration for the boiler to come on and the levels of the thermostats. Energy usage and efficiency would also be presented to the user as well as advice on how to save energy by turning off unused devices. A barcode scanning system implemented in the fridge would record the contents, allowing the user to see what food they had so that they could make a shopping list without physically checking the fridge. Suggestions for meals based on the fridge contents would be created and sent to the user if wanted.
Retina scanning would make quick and easy transactions of money for online shopping. Used in conjunction with the fingerprint recognition system, users could purchase goods online without requiring a debit or credit card. Because each individual has a unique retina and fingerprint then fraud would be near impossible and so the system would be much more secure than the current one. This system would take much less time than inputting card numbers and so the user would feel happier about online shopping, especially on their phone.
