Abstract
Abstract The invention is meant to be used on the thigh above the knee. The innovative idea is a concave bottom (FIG. 2 a), which corresponds to the shape of the thigh and a flat surface (FIG. 2 b). Thus, the upper limb can rest on the thigh. In addition, the wrist is more solidly placed in this work position. The upper limb stays better in its position. There is no need to make an unnecessary movement with it or flex it. The upper limb acts as a weight to the ergonomic mouse pad.
