A computer mouse comprises left and right function buttons for operation by a users index and middle fingers and further comprises extra function buttons 2, 3. The extra buttons are preferably located on the underside of an arc or bracket 1 and are positioned over the left and right buttons for operation by the user raising their index or middle finger. Operation in this manner does not compromise the users grip on the mouse. The mouse may be used with a virtual reality device. |
