Abstract
A temporal data control system that uses a hand held, mobile scrubwheel that includes two position indicators and an activation switch. As a user moves the scrubwheel about on a surface of a position sensing tablet a computer controls the movement of a cursor on a display. The computer also displays one or more temporal sequences, such as video sequences, on the display. Movement of the scrubwheel is detected by the computer allowing the user to position the cursor on a sequence to be controlled which the computer interprets as selecting the sequence. The computer detects rotation of the scrubwheel and controls the forward and backward motion (and speed) of the sequence responsive to the rotation. By moving the device to another location on the surface the user can select another sequence to control. The user can 'point-and-scrub' temporal sequences.
