CAPACITIVE SENSORS FOR GRIP SENSING AND FINGER TRACKING
First Claim
1. A capacitive sensing apparatus usable with an electronic device for grip sensing and/or finger tracking, wherein the capacitive sensing apparatus comprises:
- first capacitive sensors comprising first strips spatially arranged substantially along a first line, the first strips having respective lengths and spacing(s) between the first strips; and
second capacitive sensors comprising second strips spatially arranged substantially along a second line substantially parallel to the first line, the second strips having respective lengths and spacing(s) between the second strips.

Abstract
Mobile devices are increasing aware of the environment surrounding the mobile devices. In many applications, it is useful for the mobile device to be able to sense different types of hand grips and/or where fingers are positioned with respect to the mobile device. The present disclosure describes a capacitive sensing apparatus particularly suitable for sensing hand grips and/or finger tracking along edges of a mobile device. The capacitive sensing apparatus comprises strips arranged along two lines, and the respective lengths and spacing are designed to allow optimal response behavior for sensing hand grips and/or tracking fingers.
