The sensor game is an app where teenager between 12 to 16 years can explore the sensors in their phone. In our app, we implemented the light as well as the proximity sensor. According to the amount of light the sensor registered, the mood of the doll changes. The doll has 4 different moods: Sad, Neutral, Smile and Dance. Every mood has a different background music as well. The proximity sensor knows only the two moods Sad and Dance as the phone can meassure only two different states.
