I have two concepts for the final project and both of them are mainly about dragging gesture.
The first one is a multitouch puzzle game which allows kids to learn Chinese characters through doing the puzzles made up by the strokes of Chinese characters. The goal for this game is to make the boring and difficult learning process more appealing for kids.
The second concept is a multitouch app which provides various characters, scenes and objects to help service designer quickly generate scenarios video of their design. Since I worked as service designer in previous course, I found it really tricky for designers to generate scenarios. It always required designer with the skills of sketching and video editing. And their is no tool in the market that worked for that specific purpose. So I think an app might be helpful.
