Patent ID: 7986304

Claim:
A computer input device, comprising: a sensor configured to sense movement of the input device and, for each sensed movement, generate a respective first signal indicating the respective sensed movement; and an input element configured to generate a second signal when operated; wherein: the computer input device is adapted for transmitting to a processor data for instructing the processor to move a graphical object in a direction corresponding to a direction of the movement indicated by the respective first signal; in response to the generation of the second signal, correspondence of movement of the graphical object to the movement indicated by the first signal is reversed, such that, in response to subsequent sensed movement of the device, the processor moves the graphical object in a direction that is opposite to a direction that corresponds to the subsequent sensed movement; the input device is a computer mouse; and the input element is a button positioned on a side of the mouse that extends perpendicular to a surface on which the mouse rests when the mouse is in position for causing the movement of the graphical object in the direction corresponding to the direction of the movement indicated by the first signal, at a front half of the mouse.
