摘要:
The present invention provides a touch sensor track point (and methods) for a computer such as a laptop or portable device (e.g., PDA, cellular phone, etc.). The touch sensor track point includes a shaft (e.g., typically positioned on a keyboard) and a set (at least one) of directional sensors positioned over a top surface of the shaft. The set of directional sensors can detect manipulations in three dimensions (up-down, left-right, and in-out). In a typical embodiment, the touch sensor track point will cause a computer cursor to move in a direction that corresponds to a location on the set of directional sensors at which a vertical touch is applied. With such a capability, the touch applied to the set of vertical sensors can optionally be substantially horizontally motionless.
