1. An apparatus, comprising:
- a processor;
a touch sensing device coupled to the processor;
a force determining module operative on the processor to;
receive a detection signal from a first portion of the touch sensing device;
determine a first contact area of the first portion at a first instance based upon the detection signal;
map the first portion to a target operation;
determine a second contact area at a second instance;
determine a difference in the first and second contact areas; and
send control instructions to perform the target operation based on the determined first contact area and at an operation rate proportional to a difference in the first and second contact areas.

Abstract
An apparatus may include a processor and a touch sensing device coupled to the processor. The apparatus may further include a force determining module operative on the processor to receive a detection signal from a first portion of the touch sensing device, determine a contact area at the first portion based upon the detection signal, map the first portion to a target operation, and send control instructions to perform the target operation based on the contact area.

11. An article comprising a non-transitory computer-readable storage medium containing instructions that when executed by a processor enable a system to:
-
receive a signal indicating a contact event in a first portion of a touch sensing device; map the first portion to a target operation; determine a first contact area of the contact event at a first instance; determine a second contact area at a second instance; determine a difference in the first and second contact areas; and send control instructions to perform the target operation at an operation rate based upon the determined first contact area and at an operation rate proportional to a difference in the first and second contact areas. - View Dependent Claims (12, 13, 14, 15, 16, 17, 18)

19. A method, comprising:
-
detecting a signal at a first instance that exceeds a threshold in a first portion of a touch sensing device; determining a first contact area associated with the signal at a first interval after the first instance; determining a second contact area at a second instance, the second contact area being greater than the first contact area; comparing the first and second contact areas; mapping the first portion to a target operation; determining a first operation rate based on a difference between the first and the second contact areas or based on a proportional ratio of the first and second contact area; and sending control instructions to perform the target operation at the first operation rate in accordance with the comparison. - View Dependent Claims (20, 21, 22, 23, 24)
