Technical Field
[0001] This utility model relates to the field of wearable device technology, specifically a wearable electronic device capable of capturing and transmitting hand movement information. Background Technology
[0002] Data gloves provide real-time feedback to computers or other devices by sensing information such as the user's hand movements, postures, and pressure. Users can use simple gestures to control or interact with devices, allowing computers to understand human behavior. Data gloves have wide applications in virtual reality, augmented reality, robot control, and medical rehabilitation. Controlling corresponding functions through user gestures makes human-computer interaction more intelligent and natural.
[0003] Currently, most gesture recognition methods utilize visual sensors, such as structured light sensors, binoculars, or LiDAR sensors, which are easily affected by ambient light. However, with technological advancements, wearable devices capable of capturing human movements are evolving towards greater sensitivity, accuracy, adaptability, compactness, and intelligence. Data gloves offer numerous superior features in capturing hand movements and acquiring gesture information, such as being unaffected by ambient light and possessing strong anti-interference capabilities.
[0004] Existing data gloves typically employ multiple sensors, including inertial sensors, potentiometers, or joint sensors, to calculate finger flexion. These sensors are mounted on the upper part of each finger joint to calculate the angle and movement trajectory between the joint and the palm as the finger flexes. Compared to the sensors in existing data gloves, fiber optic sensors offer advantages such as high sensitivity, fast response speed, small size, light weight, and low power consumption. Applying them to gesture recognition technology would significantly enhance the advantages of gesture recognition. Utility Model Content

[0028] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.
[0029] Please see Figures 1 to 8 This embodiment provides a wearable electronic device capable of capturing and transmitting hand movement information, including the main body 1 of a data glove. For example... Figure 1As shown, the main body 1 includes a palm sleeve and five finger sleeves for wearing on the wearer's hand. The main body 1 is made of elastic fiber material to fit the wearer's hand. A clip 4 is fixedly attached to the finger sleeves of the main body 1, a clip 3 is fixedly connected to the palm sleeve, and a main unit 5 is also fixedly attached to the palm sleeve. When the main body 1 is worn, the clip 4 is attached to the wearer's fingers, the clip 3 is located on the back of the wearer's hand, and the main unit 5 is attached to the wearer's wrist.
[0030] The main body 1 is also equipped with a signal mechanism 2, which includes a light source 21, a receiver 22, and an optical fiber 23, such as... Figure 2 and Figure 3 As shown, the light source 21 and receiver 22 are fixedly connected to both ends of the optical fiber 23. A light-shielding layer 24 is sleeved on the outer wall of the optical fiber 23 to block external light from contacting the optical fiber 23. A sleeve 25 is sleeved on the outer wall of the light-shielding layer 24 to block external impacts and protect the optical fiber 23. Connectors 26 are fixedly sleeved on the outer walls of both the light source 21 and the receiver 22, and the two connectors 26 are fixedly connected to both ends of the sleeve 25. A protective layer 27 is fixedly sleeved on the outer wall of the connector 26 to protect the connector 26.
[0031] like Figure 4 and Figure 6 As shown, the signal mechanism 2 is configured with five components. The protective layer 27 on the outside of the light source 21 is fixedly connected to the outer wall of the sleeve 4. The upper end of the clip 3 has five sliding grooves, and the protective layer 27 on the outside of the receiver 22 is slidably installed in the sliding grooves on the clip 3. The upper end of the clip 3 is also fixedly connected to five mounting blocks 31. Springs 32 are installed inside the mounting blocks 31, and one end of the springs 32 extends out of the mounting blocks 31 and is fixedly connected to the connector 26 on the outside of the receiver 22. The springs 32 apply a pulling force to the connector 26 on the outside of the receiver 22 in the direction of the host 5, thereby ensuring that the optical fiber 23 fits on the wearer's finger after the main body 1 is worn. To prevent the optical fiber 23 from becoming crooked and detaching from the wearer's finger when the wearer's finger is bent, as shown in the figure... Figure 1 As shown, multiple limiting rings 11 are installed on the finger sleeve of the main body 1. The optical fiber 23 slides through the limiting ring 11, and the limiting ring 11 limits the optical fiber 23 to prevent the optical fiber 23 from becoming skewed.
[0032] The light source 21 is set as an infrared light-emitting diode or a miniature LED, preferably an infrared wavelength light source 21, such as a light source with wavelengths of 650nm, 850nm, or 940nm. Other wavelength light sources can also be selected according to actual usage requirements. The receiver 22 is set as an infrared receiving transistor or a photoresistor as the receiving end, and it is important to ensure that it matches the emitted light wavelength of the light source 21. The optical fiber 23 is made of 0.5mm diameter high-transmittance plastic optical fiber 23 after grinding and removing part of the fiber core. It has a certain degree of toughness and flexibility, and can be bent. Compared with ordinary optical fiber 23, it has less light loss, which can effectively reduce the power consumption of the product. Moreover, the specially treated optical fiber 23 has the characteristic of light loss when bent. The light emitted by the light source 21 can be conducted to the receiver 22 through the optical fiber 23. When the wearer's finger bends, the light flux received by the receiver 22 from the optical fiber 23 changes, causing a change in the electrical signal in the circuit. The change in electrical signal is then obtained by the acquisition circuit to obtain the sensor bending data.
[0033] The host 5 and receiver 22 are connected by a circuit. The host 5 contains an integrated PCB circuit board and power supply. The PCB board has three reserved interfaces: one for connecting to the signal mechanism 2 driver, one for connecting to the light source 21, and one for connecting to the receiver 22 for data acquisition. The host 5 also has multiple reserved interfaces to connect to multiple signal mechanisms 2. A communication interface is reserved, which shares the same interface as the power interface. The communication interface can be used to receive gesture data from the data glove. The power interface introduces power to the power management module, which provides reliable and stable power to each other module.
[0034] The circuit structure inside host 5 is as follows Figure 7 As shown, the communication module can be a USB port or an RS232 port, and simultaneously draws 5V DC power from it into the power management module. The power management uses a low-dropout linear regulator and selects different load capacitors according to the load to reduce voltage fluctuations at the load end. Multiple regulators power different modules. The sensor drive module, in addition to providing the current required by the light source 21, can also adjust its luminous power to improve the differences between multiple fiber sensors. The data acquisition module, besides acquiring the raw data from the signal mechanism 2, can also adjust the voltage in the circuit connected to the signal mechanism 2 to change the magnitude of its raw data. The data acquisition module, in conjunction with the sensor drive module, can adjust the sensitivity of the receiver 22. The data acquisition module can be connected to a resistor to convert the current variable in the signal mechanism 2 circuit into a voltage change, then obtain a digital value through an analog-to-digital converter chip, and transmit the digital value to the data processing and control module within the host 5.
[0035] like Figure 8As shown, the data processing and control module is a programmable control chip, which can be a microcontroller or a programmable gate array. The control module works in conjunction with the sensor driver module and the data acquisition module to power the receiver 22, acquire data, and then disconnect the power. Since the main body 1 has five signal mechanisms 2 installed, this sequential acquisition reduces circuit power consumption. Each time data is acquired from signal mechanism 2, it is stored in the chip. After all signal mechanisms 2 in the data glove have acquired data once, the data is processed, packaged, and awaits reception at the communication port. When the communication port receives a data request, the complete processed and packaged data is sent to the requesting device through the communication port.
[0036] To increase the stability of the main unit 5 when mounted on the wearer's hand, an elastic cord 51 is provided between the locking strip 3 and the main unit 5. The elastic force of the elastic cord 51 pulls the locking strip 3 and the main unit 5 closer together, thereby further securing the main unit 5 to the wearer's wrist. To prevent the locking strip 3 from flipping due to the contraction force of the elastic cord 51, an elastic band 34 is fixedly connected to the lower end of the locking strip 3. The locking strip 3 and the elastic band 34 are combined into a ring structure, which further limits the locking strip 3.
[0037] When the hand is clenched into a fist, a contraction arc will occur above the palm. In order to ensure that the clip 3 fits the back of the wearer's hand, the clip 3 is set as a three-segment structure, with connecting blocks 33 rotating between each segment. The clip 3 is bent by two connecting blocks 33, thereby keeping the clip 3 fit the back of the wearer's hand.
[0038] Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the appended claims and their equivalents.
