A computer mouse-mat, designed for use when attached to the thigh. The smooth surface of the mat allows efficient mouse-roller action, even when the working surface on the mat is rounded rather than flat. Barriers 4 at the sides of the working area ensure retention of the mouse 1 on the mat 3, even when not held by the hand. The knee mouse-mat allows users to be comfortably seated during operations, avoiding injuries due to repetitive strain (as are common after prolonged periods of usage). Many alternative surface and barrier designs are detailed for particular purposes in the specification. |
