Description

Technical Field

[0001] The present invention relates to an intelligent wearable device, and in particular to an intelligent wearable headband for totally blind or semi-blind people. Background Art

[0002] Blind people refer to those who have lost one or both eyesight due to illness or accidental injury. Blind people can be divided into two categories: congenital blindness and acquired blindness. How to effectively help them achieve better autonomy in their studies, work and daily life has become a key issue of concern to society.

[0003] Visual impairment is due to congenital or acquired reasons, which leads to partial or complete loss of function of the visual system and inability to accurately identify external objects. According to relevant standards, people with visual acuity less than 0.3 or a visual field less than 20 degrees are considered visually impaired. Depending on the degree of impairment, visual impairment can be divided into two categories: those with visual acuity values ​​above 0.03 but less than 0.3, or a visual field less than 20 degrees are considered amblyopia; and those with visual acuity values ​​less than 0.03 are considered total blindness. Amblyopic patients can usually still rely on vision to carry out daily activities, but they will encounter certain difficulties in observing objects and usually need to use optical aids or special magnification devices to help identify them.

[0004] Compared with other visually impaired patients, the challenges faced by totally blind people in their daily lives are more severe. They cannot rely on vision at all and usually need to use other senses, such as touch or hearing assistive devices to replace visual functions. Although many information accessibility technologies and equipment have been applied to totally blind people, the second sample survey in my country shows that only 7.97% of visually impaired people have received assistive device services, including 14.49% in cities and only 5.82% in rural areas.

[0005] Wearable guidance devices refer to assistive devices that can detect the wearer's surroundings and help them cope with various situations in complex environments without relying on visual information through data analysis. Smart wearable headbands for people with total or partial blindness are non-visual assistive devices that make full use of senses such as hearing and touch to make up for visual defects and aim to improve the quality of life of the visually impaired. This type of equipment covers many aspects of daily life, work, study and entertainment for the visually impaired, such as mobile phones for the blind, talking clocks, canes, Braille books, etc.

[0006] In summary, smart wearable headbands are of great significance in improving the quality of life and work efficiency of people with total or partial blindness. However, there are many types of existing wearable guidance devices, but they often have single functions and poor scalability, and it is difficult to meet the requirements of ease of use, applicability, simple portability and scalability. Summary of the invention

[0007] The purpose of the present invention is to provide a smart wearable headband for totally blind or semi-blind people in order to overcome the defects of the above-mentioned prior art. The headband provides users with accurate navigation functions by connecting to a mobile phone. The system can receive the destination information input by the user through voice in real time, and accurately guide the user along the planned path in combination with the satellite positioning data of the mobile phone. Through the vibration motor and electronic compass, the user can sense the direction of travel and navigate based on tactile feedback.

[0008] The present invention provides an intelligent wearable headband for totally blind or semi-blind people, comprising: a headband body, an electronic compass, a vibration motor module, a control mainboard, a satellite positioning module, a Bluetooth communication module, and a battery; the electronic compass, the vibration motor module, the satellite positioning module, and the Bluetooth communication module are all connected to the control mainboard for communication;

[0009] A plurality of vibration motor modules are arranged inside the headband body to stimulate the wearer's skin and prompt the wearer's direction of travel through vibrations in different directions;

[0010] The electronic compass is arranged inside the headband and is used to detect the azimuth of the direction the wearer is facing in real time and transmit the signal to the control mainboard;

[0011] The control mainboard is the core processing unit of the entire system. The control mainboard is used to receive and process the azimuth information from the electronic compass and the direction of travel information from the satellite positioning module, and perform data processing according to a preset algorithm. The control mainboard communicates with the user's smartphone or other device through the Bluetooth communication module to obtain the destination information input by the user. The control mainboard controls the vibration mode of the vibration motor module according to the received azimuth data and destination information, thereby delivering direction instructions to the user; the Bluetooth communication module can also be used to receive update information from the mobile phone, such as road closures or route changes.

[0012] The satellite positioning module obtains the real-time location information of the wearer and determines the direction of travel; the satellite positioning module transmits data with the control mainboard, and transmits the direction of travel information obtained by the satellite positioning module to the control mainboard;

[0013] The battery is used to provide power support for the above-mentioned electronic components.

[0014] Furthermore, the headband body is made of skin-friendly material.

[0015] Furthermore, the vibration motor modules are evenly distributed in a ring shape on the inner side of the headband body, and there are eight of them, corresponding to eight directions respectively, to provide directional guidance for the wearer through vibration sensations in different directions.

[0016] Furthermore, the outer side of the vibration motor module is covered with a medical-grade anti-allergic silicone film.

[0017] Furthermore, the control mainboard is provided with a variety of mode selections, and the wearer can select different vibration prompt modes according to the environment, such as continuous vibration, intermittent vibration, intensity changes, etc., to adapt to different travel needs. The number and position of the vibration motors are optimized to provide clear vibration feedback in different directions. Each vibration motor is connected to the control mainboard and vibrates in a preset mode according to the received direction signal to prompt the user's current travel direction.

[0018] Furthermore, the Bluetooth communication module has a low power consumption design to extend the battery life of the device, and has the characteristics of being compatible with a variety of devices and is suitable for mobile phone devices of different models.

[0019] Furthermore, the headband body adopts an adjustable design and can be adjusted according to the wearer's head size to ensure comfortable wearing and improve the accuracy of vibration perception.

[0020] Furthermore, the data acquired by the mobile phone can be transmitted to the guardian through software, thereby achieving the purpose of remote monitoring.

[0021] Furthermore, the battery is a lithium-ion battery, which has a large capacity and is light in weight and is suitable for long-term use.

[0022] Furthermore, the battery is designed at the rear of the headband body to balance the weight distribution of the headband and improve the wearing comfort. The battery is connected to each component through internal wiring to ensure that the system can operate normally in any situation.

[0023] The smart wearable headband realizes accurate navigation for totally blind or partially blind people through the coordinated work of the above modules. When the user inputs the destination through voice, the system automatically calculates the optimal route and provides feedback on the direction of travel to the user through the vibration motor module. The electronic compass and satellite positioning module detect the user's direction and position in real time to ensure the accuracy of navigation. In addition, the control motherboard can also adjust the intensity and mode of vibration feedback according to different environmental conditions to further enhance the user experience.
