Initial idea and sketch
The idea is inspired by the traditional game catching. The catcher will wear shoes with red LED lights. The healer will wear shoes with yellow LED lights. The rest of the players will wear shoes with orange LED lights. All the shoes will have sound sensors attached to them. The catcher upon getting close to a player will stomp his/her shoes. If the shoes of the catcher and his/her victim are close enough, the sound sensors will be triggered. The LED lights of the victim will change. The healer can change the players that are caught through stomping his/her shoes near the affected players to “save” him/her.
After discussion, we decided to use slippers instead of shoes. We feel the use of slippers produces a more comical effect as compared to shoes. It adds to the fun in our proposed game. At the same time, we also decided to use light sensors instead of sound sensors to trigger the change in color of the LED lights. We realized if sound sensors are used there is a possibility of the catcher “committing suicide” by stomping his/her slippers near his/her victim. The sound he/she produced with his/her slippers will also trigger his/her own slippers. Therefore, we decided to use light sensors instead.
