Abstract: This document describes techniques and devices for occluded gesture recognition. Through use of the techniques and devices described herein, users may control their devices even when a user's gesture is occluded by some material between the user's hands and the device itself. Thus, the techniques enable users to control their mobile devices in many situations in which control is desired but conventional techniques do permit effective control, such as when a user's mobile computing device is occluded by being in a purse, bag, pocket, or even in another room.

In response to determining that the touch input traverses a distance that is greater than the threshold physical distance, the processor scrolls the plurality of scrollable items.

Abstract: A graph display system that represents graph nodes as grid cells in a two-dimensional grid. Graph edges are represented by placing the edge's nodes in adjacent grid cells, thus eliminating the entanglement of edges that are typically drawn as lines between scattered nodes. Relatedness of two nodes sharing an edge is indicated by the edge's weight. The display system prioritizes placement of higher weight edges such that more related information is grouped together in nearby grid cells. Any graph with n nodes and e edges can be displayed and browsed.

Abstract: A touch input device includes a touch sensor and a wake-up control unit. The touch sensor includes a piezoelectric sensor and a detection signal generating unit. The touch sensor outputs sensing signals corresponding to displacement amount of a push and relaxation of the push of an operation surface, and a displacement direction. The detection signal generating unit outputs a displacement detection signal from the sensing signal. The wake-up control unit detects a push from a change in a voltage of the displacement detection signal. The wake-up control unit starts clocking upon detection of the push, and generates and outputs a wake-up signal when detecting relaxation of the push based on the change in the voltage of the displacement detection signal within a detection time.
