Abstract
In a method of input sensing and exclusion, an input is detected within a sensing region of an input device. It is determined that the input is along an edge of the input device. It is then determined whether the input satisfies exclusion criteria. Responsive to satisfaction of the exclusion criteria, the input is excluded from consideration as valid input.
Claims16
A method of input sensing and exclusion comprising:
- detecting a first input within a sensing region of an input device;
- determining said first input is along an edge of said input device;
- determining whether said first input, in and of itself, satisfies exclusion criteria;
- responsive to satisfaction of said exclusion criteria, excluding said first input from consideration as valid input;
- detecting a second input within said sensing region;
- determining an orientation of a major axis of said second input;
- and
- responsive to determining that said major axis of said second input points toward said first input, excluding said second input from consideration as valid input.
