Input device having a dimensionally configurable input area
First Claim
1. A user input device, comprising:
- a first capacitive area defined by a first electrode;
a second capacitive area defined by the first electrode and a second electrode; and
a processing unit operatively connected to the first electrode and the second electrode;
wherein the user input device is configured to;
determine a predicted input accuracy for a touch input on the user input device, the predicted input accuracy based at least in part on two or more successive prior touch inputs applied to the first capacitive area;
define a dimensionally variable input area within the second capacitive area based on the predicted input accuracy; and
execute an operation in response to receiving the touch input within the dimensionally variable input area.

Abstract
Embodiments are directed to a user input device and methods for expanding an input area in response to an estimation of the accuracy of touch input or the likelihood that a series of touches will hit an intended touch target area. In one aspect, an embodiment includes a first capacitive area defined by a first electrode and a second capacitive area defined by the first electrode and a second electrode. The embodiment further includes a processing unit that may be configured to, in a first mode, execute an operation in response to a touch received in the first capacitive area. The processing unit may be configured to, in a second mode, execute the operation in response to the touch received in the second capacitive area.
