Claims

1. A handheld rehabilitation control device for hand sensory re-education and motor function training, connected to a display device for displaying a game interface, the handheld rehabilitation control device comprising: a housing; a controller disposed within the housing; an inertial measurement unit disposed within the housing and electrically connected to the controller, for detecting a wrist movement to generate sensory data; a joystick module disposed on the housing and electrically connected to the controller; a first tactile brain-guided array module disposed on the joystick module and electrically connected to the controller; a second tactile brain-guided array module disposed on the front side of the housing and electrically connected to the controller; a power supply module disposed within the housing and electrically connected to the controller; and a wireless communication module disposed within the housing and electrically connected to the controller, wherein... The wireless communication module is wirelessly connected to the display device to transmit the sensing data to the display device. The display device is used to determine, based on the sensing data, that the wrist movement corresponds to one of a plurality of predetermined movement types, and to execute a corresponding game action corresponding to the first movement type on the game interface. The controller is further used to drive the first haptic brain-guided array module or the second haptic brain-guided array module to generate a haptic feedback signal.

2. The handheld rehabilitation control device for hand sensory re-education and motor function training as described in claim 1, wherein the predetermined movement types include ulnar wrist deflection, radial wrist deflection, wrist extension, wrist flexion, wrist pronation, and wrist supination.

3. The handheld rehabilitation control device for hand sensory re-education and motor function training as described in claim 1, wherein the game interface includes a plurality of game stages, which sequentially include a bait preparation stage, a casting stage, a waiting-for-bite stage, a reeling stage, and a catch inspection stage.

4. The handheld rehabilitation control device for hand sensory re-education and motor function training as described in claim 3, wherein the bait preparation stage includes: displaying a plurality of bait options on the game interface; receiving a wrist pronation or a wrist supination, the wrist pronation and the wrist supination corresponding to a bait selection operation; generating a first texture tactile feedback corresponding to one of the selected baits through the first tactile brain-guided array module or the second tactile brain-guided array module when receiving the wrist pronation or wrist supination; and attaching the selected bait to a virtual fishing line.

5. The handheld rehabilitation control device for hand sensory re-education and motor function training as described in claim 4, wherein the casting stage includes: displaying a plurality of target fish at different positions on the game interface; receiving a wrist ulnar deflection action corresponding to the casting action; calculating a casting distance based on the amplitude and speed of the wrist ulnar deflection action; and displaying on the game interface that the virtual fishing line has moved to a target position corresponding to the casting distance.

6. The handheld rehabilitation control device for hand sensory re-education and motor function training as described in claim 5, wherein the waiting-for-bite phase includes: entering a waiting state after the virtual fishing line reaches the target position; generating a random waiting time; triggering a fish bite event after the random waiting time ends; and generating a vibration tactile feedback through the first tactile brain-guided array module or the second tactile brain-guided array module to prompt the user when the fish bite event occurs.

7. The handheld rehabilitation control device for hand sensory re-education and motor function training as described in claim 3, wherein the thread-rolling phase includes: displaying a thread-rolling progress bar on the game interface; receiving a plurality of thread-rolling actions, the thread-rolling actions including a circular sliding operation through the first tactile brain-guided array module, a radial wrist deflection action, and a ulnar wrist deflection action; updating a progress value of the thread-rolling progress bar according to the thread-rolling actions; performing a decay operation on the progress value when the progress value is not continuously updated; generating tactile feedback corresponding to the tension of a fish struggling through the first tactile brain-guided array module or the second tactile brain-guided array module during the thread-rolling phase; and completing the thread-rolling phase and entering the fish catch inspection phase when the progress value reaches a preset threshold value.

8. The handheld rehabilitation control device for hand sensory re-education and motor function training as described in claim 3, wherein the fish viewing stage includes: receiving a wrist extension action to display visual information of a caught fish on the game interface, the visual information including the appearance image, size information and species information of the caught fish; generating tactile feedback corresponding to the scale texture of the caught fish through the first tactile brain-guided array module and the second tactile brain-guided array module; receiving a wrist flexion action to place the caught fish into a virtual bucket; and storing the information of the caught fish in a fish encyclopedia database.

9. The handheld rehabilitation control device for hand sensory re-education and motor function training as described in claim 1, wherein the first tactile brain array module and the second tactile brain array module each include a plurality of tactile brains arranged in a 4×4 array, and the tactile brains are driven by piezoelectric actuators.

10. The handheld rehabilitation control device for hand sensory re-education and motor function training as described in claim 9, wherein the controller selects a corresponding tactile mode according to the corresponding game action and generates a drive signal, the drive signal including a voltage parameter and a frequency parameter, and the controller transmits the drive signal to the first tactile brain array module or the second tactile brain array module to drive the tactile brains to perform lifting and lowering movements according to the drive signal.
