BrushMouse has been designed to resolve the problem of sweat building up on the mouse surface, making it sticky. Heat is naturally released from our palm to the empty space among the bristles. Clammy hands are thus avoided. As the contact surface between BrushMouse and the palm changes from a cohesive face to dots, the pressure from the mouse surface to the palm is diminished and distributed. Palm fatigue from using mouse for a long time can therefore be reduced too. The flexible bristles massage the user’s palm while they work.
