Abstract:
1. An input device, comprising: a touchpad having a touch sensitive surface, wherein the touch sensitive surface has at least one part comprising a topological feature, wherein the topological feature differs from topological features in other parts of the touch sensitive surface, wherein the touch sensitive surface has at least a continuous surface with demarcated parts representing zones; a switch disposed under the touchpad; and wherein the topological feature in the at least one part and the topographical features in the other parts of the touch sensitive surface are surface textures on the touch sensitive surface, the surface textures giving a user an indication of locations of the at least one part and the other parts when a user's finger touches the touch sensitive surface, wherein the surface textures are one of matte surface causing the user's finger to slide easily thereon due to low friction between the matte surface and the user's finger and glossy surface causing the user's finger to stick thereon due to high friction between the glossy surface and the user's finger, and wherein the at least one part of the touch sensitive surface comprises the glossy surface and the other parts of the touch sensitive surface comprise the matte surface.
