Multi-resolution pointing system

摘要

A user control input system for a host with a display. A controller establishes a communication link with the host and includes a first motion sensor. At least a second motion sensor is also in communication with the host. First user movement induces the first motion sensor to generate a first signal that is communicated to the host such that the host induces movement of a cursor on the display to move with respect to control objects at a first resolution. Second user movement induces the second motion sensor to generate a signal that is communicated to the host such that the host processing unit induces movement of the cursor at a second coarser resolution. The cursor can include first and second indicia such that the second indicium is moved proportional to the second motion at a finer resolution than movement of the first indicia.

1. A user control input system comprising:
a host processing unit; a display in communication with the host processing and configured to graphically display data and control objects; a controller processing unit, a communication link between the controller processing unit and the host processing unit; a first motion sensor, coupled with the host processing unit, configured to provide a first signal for inducing movement of a first cursor portion of a composite cursor displayed on the display at a fine resolution for representing a first movement; and at least a second motion sensor, coupled with the host processing unit, configured to provide a second signal for inducing movement of a second cursor portion of the composite cursor at a second resolution coarser than the fine resolution with the second resolution for representing a second movement, the second cursor portion encompassing the first cursor portion with the first cursor portion moving relative to and within the second cursor portion, wherein the first cursor portion is for selecting a desired enlarged control item within the second cursor portion.
