摘要： Devices and method are provided that facilitate improved input device performance. Specifically, the systems and methods are configured to identify a portion of an image of sensor values as corresponding to at least one sensed object in the sensing region, determine a polygon corresponding to the identified portion of the image, and determine a contact characterization of the at least one sensed object based on the polygon. The determination of a polygon corresponding to a sensed object facilitates improved contact characterization of the sensed object. For example, the determined polygon may be used to determine if the sensed object is actually more than one object. As a second example, the determined polygon may be used to determine the orientation of the sensed object. In addition, determined polygons may be used to more accurately track changes in the position of the sensed object.

摘要： The embodiments described herein provide devices and methods that facilitate improved input devices. In one embodiment, an input device is configured to determine if a sensed object includes an occluded portion using an image representative of sensor values, determine a portion of the image corresponding to the sensed object, and approximate a boundary representation of the sensed object wherein if the sensed object does include the occluded portion, the boundary representation encompasses at least part of the occluded portion of the sensed object and at least part of a non-occluded portion of the sensed object. The determination of a boundary representation corresponding to a sensed object facilitates improved characterization of the sensed object. For example, the determined boundary representation may be used to more accurately track changes in the position of the sensed object as the sensed object moves out of the sensing region.

摘要： An input device is disclosed, including a first drive electrode comprising a resistive material and a first sense electrode disposed proximate to the first drive electrode. The input device further includes a processing system which is coupled with the first drive electrode and the first sense electrode. In one embodiment, the processing system is configured for electrically driving a first end of the first drive electrode and electrically driving a second end of the first drive electrode to cause a change in a voltage gradient along a length of the first drive electrode. In such an embodiment, the change in the voltage gradient generates a first electrical signal in the first sense electrode. The processing system also acquires a first measurement of the first electrical signal and determines positional information along the length of the first drive electrode based upon the first measurement, wherein the positional information is related to an input object.

摘要： The embodiments described herein provide devices and methods that facilitate improved performance. Specifically, the devices and methods provide the ability to determine object information for objects causing deflection of a surface of a capacitive sensor device. The devices and methods are configured to determine an estimated deflection response associated with a deflection of the at least one sensing electrode using a set of sensor values, where the deflection was caused by one or more objects in contact with the input surface. The estimated deflection response at least partially accounts for effects of capacitive coupling with the object(s) in contact with the input surface, Object information may then be generated using the estimated deflection response. Where the input device is used to direct an electronic system the object information may be used to facilitate a variety of interface actions on a variety of different electronic systems.
