TLDR
In this article, a method of user command or data acquisition in a processing system that allows to analyze human hand and finger motions is described, and the activities are then interpreted as operations on a physically non-existent input device.Abstract:
A method of user command or data acquisition in a processing system is described that allows to analyze human hand and finger motions. The activities are then interpreted as operations on a physically non-existent input device. The resulting optical user/computer interface complements the visual screen-to-user path with a hand-to-image data acquisition link from the user to the processor unit. It allows to emulate different types of manually operated input devices (mouse, keyboard, etc.). Mechanical input units can be replaced by virtual devices, optimized for the current application and for the user's physiology. The speed, simplicity and unambiguity of manual data input will be maintained. Sensing of finger motions can generate feedback to reduce the hazard of repetitive strain injury (RSI) syndrome.read more

Method and apparatus for integrating manual input
TL;DR: In this paper, a simple proximity transduction circuit is placed under each electrode to maximize the signal-to-noise ratio and to reduce wiring complexity, and segmentation processing of each proximity image constructs a group of electrodes corresponding to each distinguishable contacts and extracts shape, position and surface proximity features for each group.

Real time perception of and response to the actions of an unencumbered participant/user
TL;DR: In this paper, a method for using an image of the human body to control real-time computer events is presented, where data regarding a participant are acquired through any means of imaging without marking the participant or requiring that he or she use or wear a stimulus source, sensing device or special clothing.
Patent
Touch screen form entry system
TL;DR: In this article, a form entry system is adapted to display a predefined form and to automatically display a pre-defined tool, such as a keyboard, menu, calculator, etc., to facilitate inputting information in a respective field of the form or chart.
Patent
Video image system for personal identification
TL;DR: In this article, a video image system for rapidly (in a few seconds) recording a person and his identification (ID) card makes video images of the person's hand palm and face along with the ID card presented by the person that may be a badge, card, drivers license, passport, or other item issued by some authority.
Patent
Real-time recognition of pointing information from video
TL;DR: In this article, an occurrence of a predefined object in an image is recognized by receiving image data, convolving the image data with a set of predefined functions to analyze the image features into occurrences of pre-defined elementary features, and examining the occurrences for an instance of a combination of the elementary features that is characteristic of the predefined objects.
Patent
Video computational shared drawing space
TL;DR: In this paper, a display unit (10) which displays a composite image (38), a stylus (24) which is used to "write" on the composite image, a way of detecting (20) the position of the stylus and a video camera (12) mounted a short distance away from the video display (11) and aimed at the image, and a light (23) which provides uniform illumination to the image.
