interaction systems in mobile devices. In addition to traditional capacitive touch systems, a stylus is becoming mainstream, which is a very useful feature for large-sized tablet PCs [1]. However, wearable devices, which are composed of inevitably small display panels, need a new interaction system for improved convenience. This paper presents a virtual rotating gesture-recognition IC (VRGR-IC) on a bezel area for a wearable device employing a circular display. For an implementation of the VRGR, the sensors should be placed below the bezel. However, the bracket to assemble the display and main body of a wearable device makes it unable to place any sensors in that position, as shown in the top of Fig. 26.2.1. To alternatively implement that function, two key features of this work include: 1) an integrated capacitive
