A substantially flat control device which a user pushes with two or more fingertips to generate an input, the input being associated with the direction and strength of the combined force applied to the device. The device may be a platform which fingertips rest on and push against, or a platform with a shallow edge which the fingertips grip and push. The device may be positioned on the wrist rest area in front of the keyboard of a laptop computer. |
