Technical Field

[0001] This utility model relates to the field of gesture recognition equipment technology, specifically a flexible gesture recognition glove that can be used for human-computer interaction. Background Technology

[0002] In the field of human-computer interaction technology, gesture recognition gloves, as a tool that can directly capture human hand movements and convert them into interactive commands, are widely used in various scenarios. Their core requirement is to achieve effective recognition of hand movements through a stable wearing structure to meet users' needs for intuitive and convenient interaction methods. These gloves typically need to balance fit and comfort while ensuring the ability to recognize movements from different parts of the body, such as the wrist, palm, and fingertips, thereby achieving accurate command transmission and supporting the normal operation of human-computer interaction functions.

[0003] Current gesture recognition gloves have shortcomings in terms of wearing experience and adaptability: some products lack an effective flexible cushioning structure, which can easily cause friction and wear against the skin after long-term wear, and it is difficult to relieve fatigue; some products have poor breathability design, which can easily cause stuffiness when worn; at the same time, the fixing and adjustment structure of most products has a limited range of adaptation, which cannot meet the wearing needs of users with different wrist sizes and hand sizes at the same time, and cannot achieve a stable fit. This results in an incomplete overall gesture recognition range, large data acquisition errors, and difficulty in accurately transmitting interaction commands, affecting the stability and reliability of human-computer interaction. To address these issues, a flexible gesture recognition glove for human-computer interaction is proposed. Utility Model Content

The embodiments of this utility model will be described below based on its overall structure.

[0021] Reference Figures 1 to 4 In this embodiment of the invention, a flexible gesture recognition glove for human-computer interaction includes: The wrist-wearing mechanism 1 provides a housing support and motion recognition for the user's wrist and palm, and provides space and plane for the sensor to be installed. Fingertip interaction mechanism 2 is disposed above wrist wearing mechanism 1 and is used to provide wearing and motion recognition for the fingertip in use. The flexible inner liner 3 is located on the inside of the wrist wearing mechanism 1. The flexible inner liner 3 is used to provide flexible support for the user's wrist and palm, reduce shell wear and reduce user fatigue.

[0022] The above scheme employs the following: the wrist-wearing mechanism 1 provides stable support for the user's wrist and palm through its own shell structure, and performs wrist and palm motion recognition using this structure. The space and plane formed by the wrist-wearing mechanism 1 also provide a stable support foundation for sensor installation. The fingertip interaction mechanism 2 adapts to the user's fingertips through its own structure, achieving fingertip wear adaptation and completing fingertip motion recognition. The flexible inner liner 3 conforms to the inner skin of the user's wrist and palm, providing cushioning support for the wrist and palm through its own flexibility, reducing wear and tear on the skin caused by the wrist-wearing mechanism 1 during glove use, and reducing fatigue caused by prolonged wear.

[0023] The wrist-wearing mechanism 1 includes a wrist protective shell 11, a first Velcro strap group 12 fixedly connected to the lower part of the wrist protective shell 11, a rotating connecting plate 13 rotatably connected to the upper part of the wrist protective shell 11, and a palm protective shell 15 rotatably connected to the outer side of the rotating connecting plate 13. Ventilation holes are provided on the upper part of both the wrist protective shell 11 and the palm protective shell 15. A first angle sensor 14 is fixedly connected to the upper part of the rotating connecting plate 13, and a second angle sensor 16 is fixedly connected to the side of the palm protective shell 15. The rotating head of the first angle sensor 14 passes through the rotating connecting plate 13 and the wrist protective shell 11 and is fixedly connected to the rotating axis of the rotating connecting plate 13. The rotating head of the second angle sensor 16 passes through the palm protective shell 15 and the rotating connecting plate 13 and is fixedly connected to the rotating axis of the palm protective shell 15. Each first Velcro strap group 12 and the second Velcro strap group 17 consists of two elastic bandages with hook and loop fasteners installed.

[0024] The above-described solution provides the core support for the wrist-wearing mechanism 1. The first Velcro strap group 12 below it, through the cooperation of two elastic bandages with Velcro fasteners, allows the glove to be detachably fixed to the user's wrist, and the elastic bandages are adaptable to wrists of different sizes. The rotating connecting plate 13 above the wrist protective shell 11 can rotate around its axis of rotation with the wrist protective shell 11, and the palm protective shell 15 outside the rotating connecting plate 13 can also rotate around its axis of rotation with the rotating connecting plate 13. Ventilation holes on the wrist protective shell 11 and the palm protective shell 15 allow for airflow during wear. The first angle sensor 14 is fixed at the rotation axis of the wrist protector 11 through the rotating head that passes through the rotating connecting plate 13. When the wrist protector 11 and the rotating connecting plate 13 rotate relative to each other, the first angle sensor 14 can accurately detect the rotation angle between the two, thereby identifying the rotation movement of the wrist. The second angle sensor 16 is fixed at the rotation axis of the rotating connecting plate 13 through the rotating head that passes through the palm protector 15. When the rotating connecting plate 13 and the palm protector 15 rotate relative to each other, the second angle sensor 16 can accurately detect the rotation angle between the two.

[0025] The fingertip interaction mechanism 2 includes a hook-shaped sliding seat 21, which is fixedly connected to the upper part of the palm protective shell 15. A positioning threaded hole 22 is provided on the upper part of the hook-shaped sliding seat 21. An upper sliding plate 23 is slidably connected above the positioning threaded hole 22. A screw sliding groove 24 is provided on the upper part of the upper sliding plate 23. A horizontal fixing plate 25 is fixedly connected to the lower end of the upper sliding plate 23 away from the hook-shaped sliding seat 21. A fastening screw 26 is provided on the upper part of the upper sliding plate 23. The positions of the screw sliding groove 24 and the positioning threaded hole 22 correspond. The width of the screw sliding groove 24 is slightly larger than the threaded part of the fastening screw 26 but smaller than the screw head part of the fastening screw 26. The fastening screw 26 and the positioning threaded hole 22 are compatible. The device is equipped with five sets of tension sensors 27 located below the horizontal fixing plate 25. The detection end of the tension sensor 27 is fixedly connected to a connecting rope 28, and the other end of the connecting rope 28 is fixedly connected to a fingertip positioning sleeve 29. The inner wall of the fingertip positioning sleeve 29 is provided with anti-slip texture. The anti-slip texture is a continuous wave-shaped structure with a texture depth of no more than 0.5mm. The edges of the palm protective shell 15 are all rounded with a radius of 1-2mm. The edges of the wrist protective shell 11 are consistent with the rounded corner specifications of the palm protective shell 15. The outer surface of the connecting rope 28 is covered with a layer of silicone anti-slip coating with a thickness of 0.1-0.3mm and no obvious protrusions or depressions on the surface of the silicone anti-slip coating.

[0026] The above scheme is adopted: the hook-shaped sliding seat 21 is fixed above the palm protective shell 15, providing a stable mounting base for the fingertip interaction mechanism 2; the upper sliding plate 23 can slide along the direction of the positioning threaded hole 22 above the hook-shaped sliding seat 21, thereby adjusting the position of the upper sliding plate 23 to fit the palm size of different users; the screw sliding groove 24 on the upper sliding plate 23 corresponds to the position of the positioning threaded hole 22, and the threaded part of the fastening screw 26 can pass through the screw sliding groove 24 and be threadedly connected to the positioning threaded hole 22. The width of the screw sliding groove 24 is smaller than the screw head of the fastening screw 26. When the fastening screw 26 is tightened, the upper sliding plate 23 can be firmly fixed on the hook-shaped sliding seat 21 to prevent displacement during use. The horizontal fixing plate 25 provides an installation carrier for the five sets of tension sensors 27. The fingertip positioning sleeve 29 is adapted to and fixed to the user's fingertip. When the user's fingertip makes bending, stretching or other movements, it will drive the connecting rope 28 to generate a change in tension. The tension sensor 27 detects the change in tension in real time, thereby realizing accurate recognition of the fingertip movement.

[0027] The working principle of this utility model is as follows: First, the glove-wearing operation is performed by placing the user's wrist and palm inside the wrist protective shell 11 and palm protective shell 15 of the wrist wearing mechanism 1. At this time, the flexible inner lining 3 will fit the skin and form a cushioning support through its own flexible properties. Then, the first Velcro strap group 12 (composed of two elastic bandages with hook and loop fasteners) below the wrist protective shell 11 is wrapped around the wrist and glued in place, so that the gloves can be detached at the wrist and adapted to different wrist sizes. At the same time, the ventilation holes on the wrist protective shell 11 and palm protective shell 15 will allow air circulation during the wearing process, reducing the stuffiness caused by wearing for a long time, thus completing the basic wearing and comfort guarantee. When the user moves their wrist, the wrist protector 11 and the rotating connecting plate 13 connected above will rotate relative to each other. Since the rotating head of the first angle sensor 14 fixed above the rotating connecting plate 13 passes through the rotating connecting plate 13 and is fixed at the rotation axis between the wrist protector 11 and the rotating connecting plate 13, this relative rotation will drive the rotating head of the first angle sensor 14 to rotate synchronously. The first angle sensor 14 will then accurately detect the rotation angle between the two, thereby recognizing the rotation movement of the wrist. When the user moves their palm, the rotating connecting plate 13 and the palm protector 15 connected to the outside will rotate relative to each other. The rotating head of the second angle sensor 16 fixed on the side of the palm protector 15 passes through the palm protector 15 and is fixed at the rotation axis between the rotating connecting plate 13 and the palm protector 15. This relative rotation will drive the rotating head of the second angle sensor 16 to rotate synchronously. The second angle sensor 16 will then accurately detect the rotation angle between the two, thereby recognizing the rotation movement of the palm. Before performing fingertip motion recognition, the fingertip interaction mechanism 2 needs to be adjusted according to the user's hand size: Loosen the fastening screw 26 above the upper sliding plate 23. Since the upper sliding plate 23 is slidably connected to the hook-shaped sliding seat 21, and the width of the screw sliding groove 24 of the upper sliding plate 23 is slightly larger than the threaded part of the fastening screw 26, the upper sliding plate 23 can be pushed to the appropriate position along the direction of the positioning threaded hole 22. Then, the threaded part of the fastening screw 26 is passed through the screw sliding groove 24 and threadedly connected to the positioning threaded hole 22 of the hook-shaped sliding seat 21 and tightened. The upper sliding plate 23 is fixed by tightening the head of the fastening screw 26 to complete the size adaptation of the fingertip interaction mechanism 2. Then, the user's five fingertips are respectively put into the fingertip positioning sleeves 29. When the fingertips make bending, stretching or other movements, they will pull the connecting rope 28 fixedly connected to the fingertip positioning sleeve 29, causing the connecting rope 28 to produce a change in tension. The tension sensor 27 connected to the other end of the connecting rope 28 will detect the change in tension in real time, thereby accurately recognizing the fingertip movements, and finally realizing complete gesture recognition of the wrist, palm and fingertips to meet the needs of human-computer interaction.

[0028] The above description is only a preferred embodiment of the present utility model, but the protection scope of the present utility model is not limited thereto. Any equivalent substitutions or changes made by those skilled in the art within the technical scope disclosed in the present utility model, based on the technical solution and the inventive concept of the present utility model, should be included within the protection scope of the present utility model.
