Abstract
A computer input device includes a housing in the shape of a magnifying glass having a lens portion and a handle portion extending from the lens portion. The device also includes a detector mounted in the housing and operable to detect an element displayed on a computer display and to generate a corresponding detection signal and an actuator mounted on the housing. Circuitry mounted in the housing is operable to receive the detection signal, generate an actuation signal in response to actuation of the actuator, and transmit the detection signal and the actuation signal to a computer. The housing may include a partially reflective, angularly disposed beam splitter such that a user can observe an image on a computer screen through the beam splitter, and the image can be reflected to the detector. The computer may have software operable to control an image displayed on the computer monitor in response to the detection signal.
