Influence of the reduction test device of limits to gesture action demonstration, the wearing experience effect of user is preferable.
3rd, each detection means is designed as a MANET function processor and connects an athletic posture sensor, uses
Processor and the man-to-man mode of operation of sensor greatly improve processor and carry out data acquisition and information processing to sensor
Efficiency.
4th, wireless network transmissions information is relied between each detection means, it is not necessary to come by Electric Wires ＆ Cables or communication line
Realize mutual connection, it is to avoid some gesture postures are due to detection means circuit in itself and appearance design and wearing mode
Limitation and can not accurately show, or displaying gesture posture is due to detection means circuit in itself and appearance design and wears
Wearing the limitation of mode accurately can not be detected and be recognized, improve accuracy, the integrality of Hand gesture detection.
5th, each detection means independent detection gesture posture, each subordinate computer node device independently leads to host node device
Letter, it is possible to achieve the diversity of whole Hand gesture detection system constructing, has expanded the scene of test application.According to different tests
The real needs of application design different solutions, the quantity of the detection means flexibly used needed for rational determination, true
Under the premise of guarantor's certain gestures attitude detection data are complete and accurate, test resource and cost can be saved to greatest extent.
6th, on the basis of communication pattern of the data transfer based on wireless self-networking between each detection means, except main frame section
Point device can not arbitrarily change outer, and other subordinate computer node devices can arbitrarily be added to the network of host node device foundation
Exit in group or out of group of networks without extra configuration operation, so flexible active configuration mode enhances whole hand
The integrality and reliability of gesture attitude detection system, reduce the maintenance cost of system.If event occurs for subordinate computer node device
Barrier, easily can be replaced with a new subordinate computer node device very much；If host node device breaks down, also only need
New host node device is first replaced, all subordinate computer node devices are then restarted, all subordinate computer node devices are allowed certainly
It is dynamic to add in the group of networks that new host node device is set up.
It is understood that specifically described above with respect to of the present utility model, be merely to illustrate the utility model and not
The technical scheme described by the utility model embodiment is limited to, it will be understood by those within the art that, do not departing from
In the case of the spirit and scope that claim is limited, the utility model can be modified or equivalent substitution, to reach
Identical technique effect, but all within protection domain of the present utility model.
