SYSTEMS AND METHODS FOR CONTROLLING COMPUTERS AND DEVICES

摘要

Devices, systems and methods for providing input to a computer may include a body, first and second reflective elements that have at least a first configuration and a second configuration, and a movable member coupled to the body. The movable member may be configured to move from a first position to a second position under an applied load and then return to the first position. The movable member moves such that the reflective elements change from the first configuration to the second configuration. The methods may include the steps of emitting light from a registered light source, reflecting a first pattern of reflected light emitted by the registered light source from at least first and second reflective elements, moving a movable member with respect to the body to create a second pattern of reflected light from the reflective elements, and detecting a change from the first pattern to the second pattern.
