Hand gesture detection device on basis of wireless ad-hoc network modes

Abstract

The invention relates to a hand gesture detection device on the basis of wireless ad-hoc network modes. The hand gesture detection device comprises at least one detection device. The detection devices comprise movement gesture sensors, ad-hoc network function processors, backplane circuits and power sources, each detection device can be in two working modes, can be a detection device in a host mode and a detection device in a slave mode and is arranged at a hand back or palm location of a user, the detection devices are respectively arranged at locations corresponding to the distal phalanxes or middle phalanxes or proximal phalanxes of the five fingers of the user, and the user can wear the detection devices by means of gel adhesion or binding band fixing or buckle fixing. The hand gesture detection device has the advantages that the ad-hoc network function processors can be communicated with one another without electric cables or communication lines, accordingly, the wearing experience can be greatly improved for the user, and the hand gesture detection accuracy, integrity and reliability can be greatly improved; the quantities of the detection devices required to be used can be flexibly and reasonably determined, and accordingly test resources and the test cost can be saved to a great extent.

Description

technical field [0001] The invention relates to the field of gesture and posture detection, in particular to a gesture and posture detection device based on a wireless ad hoc network mode. Background technique [0002] So far, the way for human beings to disseminate knowledge is mainly through the way of text, graphics and language description, which is the way of "speech" in the so-called "precept and deed". However, another way of "teaching by example" has not been vigorously promoted. The main reason is the serious shortage of teaching resources. For example, a piano training teacher can only focus on training a small number of students at the same time. If a large-scale collective teaching mode is adopted, the quality of teaching will be deteriorated due to the inability to provide one-on-one instruction to each student. decline. Imagine using a device that can collect human body language in real time and convert it into a data format, and then use the data of the trai...

AI Technical Summary

Problems solved by technology

[0006] 1. Limited by the constraints of gloves, the user's wearing experience is not very good

[0007] 2. Each sensor relies on electrical cables or communication lines to achieve mutual communication, and all sensors are connected to the same data processing device. Using a single processing device for data collection and information processing of multiple sensors is inefficient.

[0008] 3. Due to the existence of electrical cables, some gestures cannot be accurately displayed due to the limitations of circuit and appearance design and wearing methods, or the displayed gestures cannot be accurately detected and recognized, and the accuracy and integrity of gesture detection are relatively low. weak

[0009] 4. After the above-mentioned piano playing hand shape detection device is worn in the form of gloves, it is not flexible enough to use as a whole, and it is inconvenient when only a single finger gesture detection is required

[0011] 6. Once a certain motion posture sensor fails, the detection device of the piano playing hand shape needs to be repaired or replaced as a whole, and the maintenance cost is high
