Joystick 4-Point Contact Switch Device - SI-11

For (With Whom)

People with upper limb functional impairment or reduced finger dexterity.

Why

We thought a switch device that makes use of the remaining finger function, and that allows multiple switches to be operated easily and enjoyably by finger, was necessary, so we made this.

How

We designed a controller that is easier to grip and operate for playing with remote-controlled toys. When operating an RC toy with both hands, controlling speed and direction, operation suited to the specific demands was needed, such as buttons that must be held down constantly.

Outcome

We found that, beyond RC operation, combining it with our own toy battery assist tap makes it possible to move several kinds of toys at the same time. Toy play became lively all at once, which led to initiative in the activity and intrinsic motivation.
