Choosing the right Aspect Ratio

Choosing the correct aspect ratio for the viewing surface is very important. Originally we decided we wanted to use a wide screen 16:9 ratio so we built our second prototype to these dimensions.

We soon became aware that this would cause some serious usability issues. Not only with one user be disadvantaged by being on shortest side but will allow have difficulty of reaching the far side of the screen.

Another issue was related to our Benq projector, its native aspect ratio is 4:3 and the quality decreases substantially when switched to 16:9.

For our final prototype we first thought about using a perfect square as it would allow users equal access to the table, but we thought this would be a serious compromise in the design so we choose to use an 4:3 aspect ratio .
