Toss It!

Skills: Games


Toss It is an interactive installation serves the purpose of providing kids who are 5-10 years old with a healthier way of in-house entertainment and cool facts.
The installation is an innovative gaming device where players attempt to toss the balls into the corresponding buckets to earn respective points. It requires actual body movement as input control and provide educational purposes at the same time. With this installation, we hope that children can do bits of exercises as well as to learn useful knowledge while playing games.

Final Outcome

We developed a rapid prototype of our design including a application with graphic interface running on the computer and two buckets with sensors detecting the goal.


We offer two gaming modes: the timing mode and the learning mode.
TIMING MODE: Two player compete with each other to see who can toss more balls into the buckets in the limit time.
LEARNING MODE: Player should first determine the image of a kind of rubbish is recyclable or non-recyclable, then toss the ball the corresponding buckets to earn the score. There’s a time limitation for each round and about 10 images per game.


Initial Idea

As part of my course ‘Human Computer Interaction’, we were assigned a course design to develop a multi-mode interactive system. We brainstormed and the inspiration comes as a finding that some people love to shot the wads of paper or cans into the wastebasket as if playing the basketball. We thought intuitively that this kind of habitual movement might be turned into a type of entertainment. We choose the college students as our target users as teenagers are energetic and competitive. Living together in the dorm providing them with a special environment to play this kind of game with roommates.


Setbacks and Adjustment

However, we experienced setbacks at the beginning when we started with the user analysis. The teenager interviewee generally expressed little interest towards our idea. They felt it’s too much trouble to pick up the balls after the game. Whereas, a professor said that this might be attractive to his 7-year-old son. We were inspired and decided to change our target users to kids and added educational features.


We came up with two typical scenario and draw the storyboards.



Application with graphic interface running on the computer is implemented using Processing in JAVA. I designed the user interface in a colorful  art style, emphasizing the environmental elements in accordance with our game theme.


The detection of the goal is implemented by the infrared distance sensors on the buckets. The signal will be delivered and processed by the Arduino.
