Computer Display Object Controller

摘要

A display object controller includes a sensor elevated above the keys of a keyboard. The sensor is directed to view and monitor a user's first hand in a typing position on the keyboard. The controller includes a switch positioned adjacent the spacebar of the keyboard. The sensor and switch are connected to a processor which is connected to a computer system. The switch is arranged to enable or disable display object control. When the switch is engaged by the thumb of the user's second hand, the processor is responsive to the sensor to track hand motion for controlling display objects. When the switch is disengaged by the thumb, the processor communicates with the computer system to disable tracking hand motion so the fingers may type on the keyboard without controlling the display objects. In another embodiment, a switching means is provided in software, wherein the sensor is arranged to detect the second hand performing or ceasing to perform a predetermined gesture as a command to enable or disable display object control mode.

主权项

1. A computer display object controller, comprising:
a sensor for being directed toward a keyboard for sensing movement of a first hand in the air directly over and in close proximity to the keyboard; switching means responsive to operation by a second hand; and a processor connected to the sensor and the switching means; wherein when the switching means is operated by the second hand, the processor is responsive to the sensor for communicating with a computer system to control display objects by movement of the first hand in the air directly over and in close proximity to the keyboard; and when the switching means is ceased to be operated by the second hand, the processor is arranged for communicating with the computer system to disable controlling the display objects by the movement of the first hand, so that the first hand may type on the keyboard.
