Embodiment Construction

[0019] All gesture systems currently in use either require contact with a touch screen, or require visual capture and discrimination of the user's hand based on a camera system mounted to a display. Systems according to various embodiments instead base the user's proximity to a substantially horizontal sensor panel, which may, for example, be mounted generally perpendicular to the visual display. This removes gesture capture from the display system and makes it a separate peripheral adapted to easily interface with the computer.

[0020] According to various embodiments, disclosed herein is a method for detecting page up / down, zoom in / out, up / down / right / left movement, and rotation using a combination of multiple capacitive proximity sensors. method. The proposed gestures disclosed herein cover common document / image viewer controls, however they can be easily adapted for use in other human interface devices. The multiple possible gestures can be decoded using a simple data dr...

Abstract

A plurality of capacitive proximity sensors on a substantially horizontal plane and in combination with a microcontroller are used to detect user gestures for Page Up / Down, Zoom In / Out, Move Up / Down / Right / Left, Rotation, etc., commands to a video display. The microcontroller is adapted to interpret the capacitive changes of the plurality of capacitive proximity sensors caused by the user gestures, and generate control signals based upon these gestures to control the visual content of the video display.

Description

[0001] Related Patent Applications [0002] This application claims the title "Gesture Input System Based on Capacitive Proximity" filed December 14, 2011 by Keith Edwin Curtis and Fanie Duvenhage. (Capacitive Proximity Based Gesture Input System)", which is incorporated herein by reference for all purposes. technical field [0003] The present invention relates to methods and apparatus for proximity detection, and in particular, to capacitive proximity based gesture input systems. Background technique [0004] Current document viewing software requires shortcut key combinations or pull-down menus plus a mouse to control the display of documents. Keyboard and mouse interfaces are less intuitive than gesture-based systems because specialized knowledge about system operation and command structure is required. Gesture-based systems do not require special commands because they use almost the same gestures as paper hard copy processing. Contents of the invention [0005] Th...
