Abstract: A method for remote operation of a computer having a cursor, via a wireless optical device, comprising projecting a computer output display onto a projection surface via a projecting means, generating an optical point at a desired cursor position on the projected image via the wireless optical device, capturing the image and optical point and transmitting this data to the computer, positioning the cursor on the projected image within a predefined distance of the position of the optical point, measuring a dwell time and executing a computer command when the dwell time exceeds a predefined length of time. The invention may also comprise the step of performing a calibration process to correct imperfections that can occur in the captured or projected image.
