  • Patent number: 8994670
    Abstract: A method includes detecting a first touch at a first touch location on a touch-sensitive display, detecting a second touch at a second touch location on the touch-sensitive display, and when a first distance from the first touch location to the second touch location meets a distance threshold and a second distance from the previous touch location to the first touch location does not meet the distance threshold, identifying the second touch as a new touch.

  • Patent number: 8859971
    Abstract: An optical navigation device, such as an optical navigation joystick or mouse, includes an internal redirector which may be separate or formed from material of a touch surface of the optical device. The redirector is disposed at an angle with respect to a plane of the touch surface, operative to reflect light which would otherwise strike the touch surface at a low angle and be internally reflected. The light may be reflected in a direction away from a light sensor of the device, reducing sensed internally reflected light, or may be reflected into the touch surface at a higher angle, potentially increasing a quantity of good signal. The redirector may also include portions which block light directly emitted from a light emitter, or reflected off other surfaces of the navigation device.

  • Patent number: 8736564
    Abstract: Methods and apparatus are provided related to proximity detection between a mobile device and a related object, such as a holder, holster, pocket liner, support surface, or the like. A pattern is associated with the related object or device, for example printed on a surface thereof, the pattern being discernable by a mobile device input module, such as a touch surface or optical navigation module. When the pattern is presented to the input module, the mobile device detects the pattern and may respond accordingly, for example by shifting to a standby mode or suppressing mobile device inputs.

  • Patent number: 8736559
    Abstract: A method includes determining first respective values representative of forces applied by a plurality of actuators to a touch-sensitive input device of an electronic device, controlling the actuators to cause the actuators to change the forces applied to the touch-sensitive input device, determining second respective values representative of the forces applied by the actuators to the touch-sensitive input device, and determining when there is a fault based on a change from the first respective values to the second respective values.

  • Patent number: 8669946
    Abstract: A method includes detecting a first touch at a first location and a second touch at a second location on a touch-sensitive display, determining a first force value by a first sensor and a second force value by a second sensor, wherein the first force value and the second force value are determined at a time when the first touch and the second touch are both detected, and determining a first applied force value for the first touch and a second applied force value for the second touch based on the first force value and the second force value and based on the first location and the second location.

  • Patent number: 8390569
    Abstract: An optical trackpad module is described herein. The module includes a light source and a trackpad that is optically coupled to the light source such that light from the light source can reach the trackpad. The trackpad is configured to receive an input object. The module also includes a sensor array that receives at least some of the light from the light source that is reflected off the input object. The sensor array is divided into sub-sections, and each sub-section corresponds to a portion of the trackpad. In addition, each sub-section detects at least translational movement of the input object on the corresponding trackpad portions to enable detection of rotational motion of the input object on the trackpad.
