On the next day, I tweaked the design and made sure to make everything fit perfect. To prevent the side part for falling apart from the body, I added hinges to make the folding part more steady...and it worked really well :) Inspired by the family sound memory project, I also added a simple tangible dial interface that can help navigate between different time period. When the user dials the wheel, he/she can see and hear the memory of people from different years.
Is this a good/useful/informative piece of content to include in the project? Have your say!
