Embodiment 1

[0047] VR (Virtual Reality, virtual reality) and AR (Augmented Reality, augmented reality) technologies are more and more widely used, compared with traditional PC (Personal Computer, personal computer) and mobile terminals, the biggest feature is immersion. From the perspective of physical psychology, immersion comes from three aspects: the visual authenticity brought by the 3D scene; the authenticity of the user's own sense of substitution; and the authenticity of the user's interaction with the virtual world.

[0048] In the prior art, immersive scenes created by VR and AR technologies can simulate various actual scenes. In order to meet people's higher-level needs, gesture recognition devices are used to detect user gestures to better interact with users. It can make VR or AR more realistic. Due to the relatively small range of finger movements, the current gesture recognition devices are difficult to recognize, and most devices have the problems of small recognition range...

Embodiment 2

[0072] This embodiment proposes a gesture recognition method, including the gesture recognition device described in the first embodiment. The processing module compares the opening degree of the first arm 11 and the second arm 12 with the diameter of the virtual object, and judges the grasping according to the comparison result. The state of the virtual object. That is, when the opening degree of the first arm 11 and the second arm 12 is not greater than the diameter of the virtual object, it is determined that the object is grasped; otherwise, it is not grasped.

[0073] like image 3 As shown, L1 is the length of the sliding element 132 , L2 is the length of the second boom 121 , L3 is the length of the upper first link arm 112 , L4 is the length of the second link arm 122 , and L5 is the length of the first boom 111 Length (lower limit position), L5' is the length of the first boom 111 (upper limit position), a is the projection of node o to the first half distance of L1, ...

Abstract

The invention discloses a gesture recognition device and method, and the device comprises a grabbing recognition mechanism which comprises a first arm which is configured to move along with an index finger; the second arm is hinged to the first arm and is configured to move along with the thumb; the offset detection mechanism is used for detecting the movement offset of the first arm relative to the second arm; and the processing module is in communication connection with the offset detection mechanism and is used for receiving the movement offset sent by the offset detection mechanism and calculating the opening degree of the first arm and the second arm according to the movement offset. The invention discloses a gesture recognition device. According to the human engineering principle, when fingers execute grabbing actions, finger postures can be changed, the arms capable of moving along with different fingers are arranged, the opening degree between the fingers is reflected, finger actions can be accurately recognized, the influence of accumulative errors of a sensor is avoided, and the detection accuracy is higher.

Description

technical field [0001] The invention belongs to the technical field of intelligent wearable devices, and in particular, relates to a gesture recognition device and a recognition method. Background technique [0002] At present, immersive display devices such as VR glasses are developing rapidly, but gesture recognition devices, which are a sub-part thereof, are still not popularized and cannot meet people's higher-level needs. The gesture recognition devices for interacting with immersive display devices are limited, and most devices do not involve the recognition of finger parts. [0003] In addition, the current devices involving finger motion capture still have the problems of small recognition range and accumulated sensor error. SUMMARY OF THE INVENTION [0004] Aiming at the problems in the prior art that smart wearable devices cannot perform finger movements or have large capture errors, the present invention proposes a gesture recognition device, which can solve th...
