Abstract: A method and apparatus for generating touch blob angle orientation in a touch device are described. In one embodiment, the apparatus comprises a touch processing unit operable to analyze sensor data generated from touch inputs on a touchscreen and generate touch blob information for each detected touch blob; and a filter coupled to the touch processing unit operable to filter blob orientation information from a filter output in response to detection of a finger lifting event.

Abstract: Systems and methods for protecting a mobile device screen utilize a screen protector overlying the display screen lens, wherein the screen protector includes a conductive region. The device face includes a plurality of conductors underlying the screen protector at the conductive region. The conductors are capacitively coupled in the presence of the screen protector, and are capacitively decoupled when the screen protector is removed. This allows the device to detect removal of the screen protector and to perform a responsive action such as alerting a device user that the screen protector is not installed, instructing the user to install a screen protector, storing an indication that the screen protector is not installed and transmitting an indication that the screen protector is not installed.

Abstract: A touch sensitive display for an electronic device includes a display (201) for presenting information to a user and at least four infrared transceivers (202,203,204,205) disposed about the display (201). The four or more infrared transceivers (202,203,204,205) can be disposed about the display (201) such that infrared light (206,207,208,209) from each of the infrared transceivers (202,203,204,205) projects across a surface (303) of the display (201). A controller (214), which is operable with the infrared transceivers (202,203,204,205), is configured to detect which of the infrared transceivers (202,203,204,205) has the most reflected signal (702). The controller (214) can then correlate this and other information with one of a plurality of user modes of operation. A control menu (802) can then be presented on the display (301) in accordance with the user mode of operation to mitigate finger blockage.

Abstract: A method (100) and electronic device (700) for presenting user actuation targets (1101,1102,1103) on a touch sensitive display (701) includes a controller (805) configured to determine a user actuation target arrangement (1500) having a hierarchy of precedence (1501). A display driver (809) is then configured to present the user actuation targets (1101,1102,1103) on the touch sensitive display (701) in accordance with the user actuation target arrangement (1500). This can include presenting user actuation targets (1201,1202) having a higher precedence closer to a user's finger (1206) than user actuation targets (1203,1204) having a lower precedence, or by magnifying user actuation targets (1201,1202) having a higher precedence. Precedence can be determined by most frequently selected targets, most recently selected targets, or other factors.
