Tactile user interface for an electronic device
First Claim
Patent Images
1. A method of detecting a touch input in an electronic device, the method comprising:
- generating a first signal in response to a touch input that is pivotal about an axis normal to a surface of a pliable portion of the electronic device with a first sensor embedded in the pliable portion of the electronic device;
generating a second signal in response to the touch input at the surface of the pliable portion of the electronic device with a second sensor removed from the pliable portion of the electronic device; and
detecting the touch input that is pivotal about an axis normal to the surface of the pliable portion of the electronic device based on a difference between the first sensor signal and the second sensor signal.

Abstract
A tactile interface for an electronic device includes a compliant portion, a first input sensor embedded in the compliant portion and a second input sensor. The first and second sensors produce differential output signal in responsive to tactile input forces applied in at least a common dimension or about a common axis. A processor detects and interprets the differential output signals as a tactile input at the touch input device.

2. An electronic device comprising:
-
a processor disposed within a housing of the electronic device; and a touch input device coupled to the processor, the touch input device comprising a compliant portion with a touch input surface, a first input sensor embedded in the compliant portion of the touch input device, and a second input sensor, the first and second sensors are coupled to the processor, the first input sensor pivotal about an axis normal to the touch input surface in response to a touch input at the touch input surface of the compliant portion of the touch input device, the processor configured to detect relative pivotal movement between the first and second sensors in response to the touch input at the touch input surface of the compliant portion of the touch input device, wherein the relative pivotal movement between the first and second sensors is proportional to an input of the touch input device. - View Dependent Claims (3, 4, 5)
