Prototype V - Sofware

Note: About the button design elderly people "in today's society" generally will grasp the concept of clicking buttons from similar device like TV remotes, they are probably not used to fancy menus using combo boxes etc.

Comments on design:

The back button on the the screen is a good idea as the user will generally want to go back a step if they did something incorrect.
Generally there will be quite a lot of feedback so the user knows what to do next even if they have forgot from previous times it also shows the user what the system is actually doing at the current moment in time.
This is only a prototype so the colours haven't been finalised but i thought the food group colours were ideal other than fibre as it is hard to see the text.
