description A computer mouse or pointing device has a roller 24 with a concave peripheral surface 28. The central of the concave surface 28 lies below the edges of the surface. The surface is arcuate, is 6-15mm wide (wider than a conventional scroll wheel), and is patterned (eg. striations, rhombus, triangle) to increase friction with a user's finger. Stress on a finger is reduced with this shape by improved posture.
