PROBLEM TO BE SOLVED: To provide user input devices that accept complex user input including a combination of touch and push (or pick) input.SOLUTION: Embodiments of the invention enable selective ignoring or rejection of input received from such devices in order to avoid interpreting unintentional user actions as commands. Furthermore, some input signals can be modified. The selective rejection or modification can be performed by the user interface device itself or by a computing device that includes or is attached to the user interface device. The selective rejection or modification may be performed by a module that processes input signals, performs the necessary rejections and modifications and sends revised input signals to higher level modules.

PROBLEM TO BE SOLVED: To provide a touch sensor panel used as an input device of a computer system.SOLUTION: There is provided use of a plurality of stimulation frequencies and phases for generation of a contact image on a touch sensor panel. A plurality of sense channels can be coupled to columns in the touch sensor panel, and can have a plurality of mixers. The respective mixers in the sense channels can use a circuit capable of generating a specific demodulation frequency. In a plurality of stages, rows of the touch sensor panel can be simultaneously stimulated using selected frequencies of various phases, and the plurality of mixers in the respective sense channels can be set to demodulate signals received from the columns connected to the respective sense channels using the selected frequencies. After all the stages, demodulated signals from the plurality of mixers can be used for calculation for determining a contact image to the touch sensor panel at each frequency.

PROBLEM TO BE SOLVED: To provide a touch sensor panel used as an input device of a computing system.SOLUTION: The use of multiple stimulation frequencies and phases for generating an image of touch on a touch sensor panel is disclosed. Each of a plurality of sense channels can be coupled to a column in a touch sensor panel and can have multiple mixers. Each mixer in the sense channel can utilize a circuit capable of generating a demodulation frequency of a particular frequency. At each of multiple steps, various phases of selected frequencies can be used to simultaneously stimulate rows of the touch sensor panel, and the multiple mixers in each sense channel can be configured to demodulate a signal received from the column connected to each sense channel using the selected frequencies.

PROBLEM TO BE SOLVED: To maximize the functionality of a touch sensor panel by providing certain exceptions to rejection of edge contacts.SOLUTION: The selective rejection of touch contacts in an edge region of a touch sensor panel is disclosed. In addition, by providing certain exceptions to the rejection of edge contacts, the functionality of the touch sensor panel can be maximized. Contacts in edge bands around the perimeter of a touch sensor panel can be ignored. However, if a contact in the edge band moves beyond a threshold distance or speed, it can be recognized as a part of a gesture. To accommodate different finger sizes, the size of the edge band can be modified based on the identification of the finger or thumb. Furthermore, if contacts in the center region of a touch sensor panel track the movement of contacts in the edge band, the contacts in the edge band can be recognized as a part of a gesture.

PROBLEM TO BE SOLVED: To increase effective spatial resolution and/or to expand a physical range of a sensitive device using the limited number of sensors by optimizing the shape and arrangement of a capacitive sensor electrode. SOLUTION: There is disclosed a capacitive touch sensitive device. One aspect of the touch sensitive device is a reduction in the number of sensor circuits needed for circular or linear capacitive touch sensitive devices while maintaining the same resolution and absolute position determination function for a single object. A related aspect of the touch sensitive device is a coding pattern that allows each sensor circuit to share multiple electrodes at specially chosen locations in a sensor array such that the ability to detect the absolute position of a single object over the sensor array of capacitive touch sensitive device is not compromised.
