Final Project

Concept

Minds-On came from the tilt board game( people have a board with holes and a ball on it, then they need to tilt the board to let the ball go through the maze). Usually, people play it with their hands. But in Minds-On, people can play it with their heads which means when their are nod or shake, they can tilt the board remotely. To make this installation sustainable, I designed both the maze and holes to be customizable.

The first demo

To test my idea, I first made a demo with foam board and the walls of the maze could be plugged in.

Final version(2023)

Then I found this way look stupid and not easy to operate. As a result, the final version came with magnets. The board consists of two layers and I put magnets between them. Also I put magnets into the walls, so that it look like magic.
