Human-computer interaction finger ring and implementing method

Abstract

The invention relates to a human-computer interaction finger ring and an implementing method. The human-computer interaction finger ring comprises a finger ring casing with an annular structure, wherein a rectangular casing is arranged on a ring of the finger ring casing, a microprocessor MSP430F2X1, an acceleration sensor MMA7455, a radio-frequency circuit, a battery, a flexible circuit board and a UHFPCB (ultra-high frequency printer circuit board) printed antenna are arranged in the rectangular casing, and the antenna is covered with a cover plate which allows electromagnetic wave to pass through and is made of an ABS (acrylonitrile butadiene styrene) material; and the acceleration sensor MMA7455 in the finger ring is used for detecting hand movement of a wearer, the microprocessor MSP430F2X1 is used for performing movement calculation, the action type is calculated, the corresponding action type code is modulated to a UHF carrier wave through the radio-frequency circuit according to the EPCClass1Gen2 protocol standard, sent out by the antenna and can be received by a computer through an RFID (radio frequency identification) label reader of a UHF band, the action code can be received, the human-computer interaction purpose is achieved, the cost is low, and the identification accuracy is not affected by the environment.

Description

technical field [0001] The present invention relates to electronic circuits and motion recording equipment, in particular to a human-computer interaction ring circuit and its implementation method. Background technique [0002] At present, the common human-computer interaction is mostly realized through methods such as mouse, remote control, and image recognition. The mouse needs to be operated on an operating surface, and the remote control needs to be picked up when using it, which occupies the function of hand grasping. The image recognition method is complex and costly, and the recognition accuracy is greatly affected by the environment. Contents of the invention [0003] The purpose of the present invention is to overcome the deficiencies of the prior art, and to provide a human-computer interaction ring and its implementation method for the above problems. A ring that can be worn directly on the finger for human-computer interaction. [0004] The present invention ...
