Embodiment Construction

[0016] The shape of the two wheels of the measuring sensor is shown in figure 1 . This is an enlarged front view, 3 and 4 are concentric wheels connected by a fixed shaft; 1 and 2 are two short arms connected with 4 and 3 respectively to control the rotation of the wheels. 1 and 2 can be fixed on the fingers on both sides of the joint, so that the bending of the fingers can drive the relative rotation of 1 and 2. The data glove is composed of multiple measurement sensor devices, which are respectively fixed at each joint of the hand, see figure 2 .

[0017] image 3 It is a schematic diagram of the internal structure of the two runners. Place 1 LED light at 3 places, the signal is generated by the LED light. The receiving ends of N fiber optics arranged in an arc are placed at the 4 places corresponding to the LEDs, and the density of the fiber distribution determines the accuracy of the measurement. 1 and 2 are when the two arms rotate at a certain angle, the LED light...

Abstract

The invention provides a data glove based on a CCD sensor, which adopts digital idea, and uses the mode of digital information to directly realize signal measurement, signal transmission, signal collection, signal processing and other links. A set of novel angular measurement sensor is designed to complete the measurement for a bending angle of a finger. Action information for the hand can be obtained by using a mechanical light-selecting part to complete identification and measurement to a turn angle. The information is transmitted in front of a CCD camera which directly collects and reads digital image information, and then is transmitted to computer software for processing. The novel digital data glove gets rid of the defects of complicated method and structure for processing analog quantity, high cost and the like, and has the advantages of simple structure, convenient application, low cost and the like. A virtual interactive system which uses the novel data glove as input equipment has wider range for popularization and application in virtual assembly, long-range operation and other fields, thereby being the input equipment for the virtual interactive system in the technical field of virtual reality.

Description

technical field [0001] The invention relates to a sensing device for motion measurement, especially a data glove used as an input device for a virtual interactive system. Background technique [0002] With the development of virtual reality technology, virtual hands, as a natural and efficient way of human-computer interaction, have been widely used. In the virtual environment, the data glove is an important human-computer interaction device, which can obtain hand movement information in real time, and complete functions such as capture, manipulation, and communication in the virtual environment. Some traditional optical fiber data gloves or mechanical data gloves work by converting hand movements into analog electrical signals through various sensors. circuit system to support. The existing optical data gloves based on image processing also have disadvantages such as complicated structure and working method, difficult operation, and high cost. Contents of the invention ...
