Embodiment Construction

[0051] Radio Frequency Identification (RFID, Radio Frequency IDentification) positioning can be implemented using the NFC technology that is currently being promoted. NFC technology mainly involves NFC reading and writing equipment (including chips and antennas), RFID electronic tags (including chips and antennas) and related software; among them, NFC reading and writing equipment communicates wirelessly with RFID electronic tags through antennas; RFID electronic tags are composed of coupling elements (i.e. antenna) and chips, each RFID electronic tag has a unique electronic code (ID), RFID electronic tags are attached to objects to identify the target object; RFID is a non-contact automatic identification technology, RFID electronic After the tag enters the radio frequency electromagnetic field, it obtains the induced current as the working power supply, and sends the tag information to the NFC reading and writing device, and the identification work does not require manual int...

Abstract

The invention discloses a 3D (three-dimension) man-machine interaction method which comprises the steps of: configuring electronic tags with different IDs (identification card) for a hand part, configuring a radio-frequency electromagnetic field including a 3D virtual man-machine interface imaging space; obtaining related information of the electronic tags on the hand part after the hand part enters the radio-frequency electromagnetic field; obtaining position information, movement speeds, movement directions and movement tracks of different fingers and the palm in the 3D virtual man-machine interface imaging space according to obtained related information of the electronic tags; carrying out matching treatment on the position information and a control piece or hot spot displayed in the 3D virtual man-machine interface imaging space; judging whether an action of the fingers or palm accords with touch action definition of the control piece or hot spot in the 3D virtual man-machine interface imaging space, and triggering the operation of the control piece or hot spot in the 3D virtual man-machine interface imaging space. The invention also provides a 3D man-machine interaction system. According to the technical scheme disclosed by the invention, naked 3D man-machine interaction according with the accuracy control requirements can be achieved.

Description

technical field [0001] The present invention relates to the human-computer interaction technology of terminal equipment, in particular to a 3D human-computer interaction method and system. Background technique [0002] The interaction mode of traditional display and input devices, such as touch screens and keyboards, is still in the two-dimensional stage, and is limited by the specific plane area of ​​physical devices. On the one hand, as a physical display and input device, mobile terminals pursue slimness, compactness, and portability; these two needs. For traditional two-dimensional display and input devices on mobile terminals, the amount of information displayed, the accuracy of touch points, and the convenience of operation are all different from those of desktop computers. It is necessary to have the display and input capabilities of desktop computers. The display and touch input methods will be able to overcome the limitations of the physical devices of the mobile ...
