Abstract
A method and apparatus of detecting user initiated movement by an input element handled by a user is disclosed. The method may include performing a calibration procedure that is initiated by the user via a physical movement performed by the user. The method may also include positioning at least one sensor to dynamically adjust a size of an effective workspace range capable of detecting the user's movement of the input element.
Claims20
A calibration apparatus, comprising:
- exactly one sensor capable of detecting movement of an input element;
- a tangible button coupled to the sensor and movable from a stored position inaccessible to the input element to a known calibration position selectable using the input element;
- wherein the sensor is adapted to sense the position of the input element when the input element is on the button;
- and
- wherein the calibration apparatus is configured to perform a calibration procedure that includes comparing the known calibration position of the button relative to the sensor with a sensed position of the button as detected by the sensor when the input element is placed on the button.

A method of calibrating a sensor capable of detecting movement of an input element, comprising:
- moving a tangible button from a stored position inaccessible to the input element to a calibration position that is known relative to the sensor and where the button is selectable using the input element,
- selecting the button with the input element;
- sensing, by the sensor, the position of the input element when the input element is on the button;
- and
- responsive to the selecting the button, calibrating the sensor by a calibration apparatus performing a calibration procedure that includes comparing the known calibration position of the button relative to the sensor with the sensed position of the button as detected by the sensor when the input element is placed on the button.
