The main concern derived from our design freeze presentation was that we hadn't focussed on the tangible interaction from the users. We needed to include an aspect of information that acted as a level of communication between the users. The reading of exercise was an automatic input that was shared between the users. In class we began considering what useful information could be communicated for the design.
Our most successful idea was to transfer user goals back and forth to each other. IE. if your friends fish beat you today, you can communicate through the tank display that tomorrow you intend to beat there fish by so much etc. I began looking at possible ways this could be shown through the tank. I firstly considered having two fish for each user (one to display your goal for tomorrow, and one to display your exercise achievement for that day)
After trying different designs for the two fish display, I decided it would get too confusing, as the user would need to manually adjust one of their fish, and evidently would mean each fish would need to be labeled. We discussed the use of lasers in class and how that would be possible for this design. I mocked up some sketches of how I believed this to be possible..
Initial inspiration for the magnet laser design came from a similar system that I used to have with my actual fish tank years ago. It was to clean the glass of the tank on the inside. They were magnetised and had a mesh grip material on one side of the inner tank cleaner. (images below)
