Multifunctional scroll sensor
First Claim
1. A method comprising:
- dividing an annular touch pad into a plurality of regions;
assigning each of the plurality of regions to one of a plurality of control functions;
receiving a touch on the touch pad initiated at a given point on the touch pad; and
if the given point falls within one of the regions, selecting the control function assigned to the one of the regions and receiving the touch as parametric control input for the selected control function;
wherein selecting the control function requires that the touch has rotational motion initiated at the given point.

Abstract
An apparatus and method for using a scroll sensor providing a touch sensitive control input surface for a plurality of control functions is provided. The input surface is divided into a plurality of regions. Each region is assigned to one of the plurality of control functions. At least one of these control functions accepts parametric control input. A first touch is received at one of the regions on the input surface. The control function assigned to the touched region is selected. If the selected control function is one of the control functions accepting parametric control input, a second touch on the input surface is received as parametric control input during an activation period for the selected control function. The second touch may be received as parametric control input at any point of the input surface.

17. An apparatus comprising:
-
a scroll sensor having an annular touch sensitive control input surface, the scroll sensor providing an output signal indicative of a touch on the input surface initiated at a given point on the input surface; and a controller in communication with the scroll sensor, the controller operative to (a) receive the output signal from the scroll sensor, (b) select one function from a plurality of control functions based on the given point on the input surface only if the touch has rotational motion initiated at the given point on the input surface, and (c) provide control input for the selected function based on the touch. - View Dependent Claims (18, 19, 20, 21)

22. A remote control for use with an entertainment system, the remote control comprising:
-
a scroll sensor having an annular touch sensitive control input surface, the scroll sensor providing an output signal indicative of a touch on the input surface initiated at a given point on the input surface; a transmitter for transmitting a remote control signal; and a controller in communication with the scroll sensor and the transmitter, the controller operative to (a) divide the input surface into at least two regions, each region corresponding to one of a plurality of remote control functions, (b) receive the output signal from the scroll sensor, (c) if the given point falls within one of the regions, select the remote control function corresponding to the one of the regions only if the touch has rotational motion initiated at the given point and receive the touch as parametric control input for the selected remote control function, and (d) control the transmitter to transmit a signal specifying the parametric control input for the selected remote control function.
