ABSTRACT:
A status sensing mechanism is disclosed, which comprises: a post, and a sleeve, ensheathing the post for enabling the post to slide up and down therein; wherein the post is abutted against a side of the sleeve as the inertial cursor-control device is subject to a first movement while the post is separated from the side of the sleeve as the inertial cursor-control device is subject to a second movement. By the use of the aforesaid status sensing mechanism, an improved cursor-control device can be provided, in which a sensor is used to detect and determine whether the status sensing mechanism is subjecting to the first movement or the second movement so as to issue different electrical signals corresponding to the detection to an inertial cursor processor arranged inside the cursor-control device for directing the inertial cursor processor to perform one of the following operation: (1) to perform a two-dimensional or three-dimension operation with respect to the received electrical signal for controlling the switching of the sensing capabilities of the cursor-control device, that is, the cursor-control device is controlled to be in a mode of two-dimensional detection or in a mode of three-dimensional detection; and (2) to perform either a displacement locking operation for freeing the cursor from the control of the cursor-control device, or a calculation of displacement for directing the cursor to move accordingly.
