After analysing each of our prototypes we have produced a list of the hardware requirements that takes what we feel are the best parts of each design.
Tris - With the combination of all of our designs, we could refine our specification a tad more for the hardware side of our device. After discussing it as a group i soon realised why an all-in-one device had so many advantages. One of the only advantages of having the gun was that it would be easier to hold rather than the PDA. I also feel the need for force feedback to play with the senses was an important point bought up. Some points were left out as we felt that didn't satisfy the user-centered design approach and were consistent with other age groups too. I was also pretty keen on the doctor interface, although a bit sceptical at first about it. It could help doctors identify what parts of a diet a client lacks, without them actually realising themselves. I also still feel there is room for the state of the art scales that simon mentioned in his post. Even if its not entirely necessary, its nice to step out of the realms of technology for the product.

Simon - i can see the usefulness of force feedback, like used in the phone, rumble pack or something, however if theyre using the actualy device theye gonna see a box pop up, they dont have to feel the thing rumble to see it. However, if we included a reminder or something in the device then it could work well, for example people with diabetes need to have food at certain time intervals or people who take medication need to have it at a certain time and if the device was kept in the pocket then the rumble would make them aware of the programmed reminder. The scales could be an add on which makes a huge difference in the functionality of the device as saying your eating cabbage could vary in amounts, however, indicating how much your eating would allow analysis of just how much nutrition your actually getting.
