An Atypical Mouse

4-finger computer mouse//Concept//Design//3D Printing

For a client born with four fingers and a fixed wrist, using a regular computer mouse was next to impossible. We developed a 4-finger-friendly, rounded, comfortable mouse form, with a custom-placed click wheel to allow for easy scrolling.

The challenge: My client was born with four fingers and a fixed wrist. It is extremely difficult for him to use a typical computer mouse.

The solution: A more rounded, comfortable form with a wheel on the side to allow thumb scrolling.

3D Scan- A series of images were merged together with Autodesk Remake to create a 3D model of the Client’s hand.

Sourcing internal components to most easily separate the scroll wheel from the circuit board.

Sculpting form exploratory to determine optimal hand fit.

3D printed forms to allow for comfort and usability testing.
