TH12950A3 - Wireless hand gesture control of electronic devices Via bluetooth signal - Google Patents

Abstract

The wireless hand gesture control of electronic devices via Bluetooth signal consists of 2 main parts: cuff and hand cuff. In the armband there is a control box inside which contains no one controller as a processor. Bluetooth communication module Polymer lithium battery DC voltage amplification module USB battery charger board Display of LED (OLED) LED lamp to show the working status. On-off switch And switches for entering commands and in the thimble there is a variable resistor (Variable resistor) acts as a motion detector. Of the knuckles in each finger are the thumb, forefinger, middle finger and little finger, with a variable resistor installed on two fingers each, a total of 8, and an Inertia measurement unit module. ) Which contains an accelerator detector (Accelerometer) and gyroscope (Gyroscope) for detecting rotation. And hand movements This electronic control unit can operate without hand gestures. The cable is via bluetooth independently and naturally according to the movement of the wearer's hands and fingers, convenient to wear and easy to learn and use.

Claims (3)

1. Wireless hand gesture control of electronic devices via bluetooth signal. It consists of two main parts: a cuff (1) for fitting into the user's arm and a cuff (10) for fitting into the user's hand. In the main part, the first part, the sleeve (1), contains the control box (2), inside of which the control box (2) contains a microcontroller. Bluetooth wireless communication module Lithium polymer battery Usb battery charger module And a DC voltage amplification module Which the microcontroller will do the processing and analyzing the voltage And signs Obtained as a control signal for the electronic devices that are connected to this controller through It communicates wirelessly with a Bluetooth communication module with (3) displays that display messages, operating status and results. Analyze various hand gestures Obtained from the algorithm There are (4) indicator lamps and a signal indicator lamp. It is connected to electronic equipment (5), there is a command selection switch (6) and a confirmation switch (7), and a power switch (8) and a USB port (USB) (9) for welding. Connect the controller to the computer or Used to charge the battery of the operating controller. There is an elastic strap on the armband (11) and the elastic hook on the armband (13) for adjusting the fit level. As with the main part, the second part, the thimble (10), is adjustable from the elastic strap, the thimble (12), and the elastic thimble hook (14). The thimble (10) consists of a thimble (16) for inserting the fingers of each finger: the thumb, forefinger, middle and little finger, and the thimble area (16) of each finger there is an elastic thimble (17). To increase flexibility and fit in stretching the fingers For detecting finger movement, it will be located On the part of the finger axis of each finger Which is made up of three finger axes, namely the finger core (18) is attached to the right angle device attached to the thimble (10). Can slide in - out To accommodate different finger lengths of each wearer And the tip finger axis (20) is the thimble core (16) of each finger. There is a variable resistor (21) installed at the end of the axis. The foremost finger (18) and the middle finger (19) axis are used to measure the degree of rotation of each knuckle. An inertia measurement unit module (22) is installed behind the thimble (10). Inside the inertia measurement unit (22) contains an acceleration detector. (Accelerometer) and gyroscope (Gyroscope) used for detecting the rotation and movement of the hand. 2. Wireless hand gesture control of electronic devices via bluetooth signal. According to claim 1, where an elastic wrist band (15) is connected between the sleeve (1) and the sleeve (10) to allow movement and rotation. The wrist is flexible. 3. Wireless hand gesture control of electronic devices via bluetooth signal. According to claim 1, where the algorithm converts and analyzes the motion of the hand and fingers Is the processing of pressure values that Measured by all variable resistors (21) And the signal value measured from the acceleration detector (Accelerometer) and Gyroscope (Gyroscope) located inside the inertial measurement module (22), starting from the operating mode setting (23) to set the controller whether it is for left hand or right hand. It is then sent to detector calibration section (24) for reading all of the current readings from the variable resistor (21) and sent to the changing angle section (25) for the rotation angle reading. Each hand and finger in the x (x), y (y) and z (z) axis to be sent to the processor and analysis (26) to take all readings to the directional pattern. Various hand and finger gestures are designed and sent to the gesture status display (27) for displaying the gesture status of the hand and finger movements. To send a control signal through a Bluetooth wireless communication module (28) for controlling electronic devices connected to the controller.
