Description

Technical Field

[0001] The present invention belongs to the technical field of blind guide equipment, and in particular relates to a wearable blind guide equipment for barrier-free travel and a method of using the same. Background Art

[0002] With the development of society, the travel needs of visually impaired people are increasing. As an important tool to assist visually impaired people in traveling, the importance of guide devices is self-evident. However, existing guide devices still have many inconveniences during use and are in urgent need of improvement and perfection.

[0003] 1. The headphone and data cable interface designs of the guide devices currently on the market are often unreasonable. The headphone interface is fixed and difficult to plug in. Visually impaired people often need to fumble for a long time to correctly insert the headphones when using them. This not only reduces the efficiency of use, but may also cause damage to the headphones due to improper operation. The data cable interface also has similar problems. The protective measures at the interface are insufficient. During the charging process, it is easy to loosen or even be damaged due to external force collision or misoperation, affecting the charging stability of the device. This inconvenient interface design has brought many troubles to the daily use of visually impaired people and limited the convenience and practicality of the guide devices.

[0004] 2. The cover design of guide equipment is one of the key factors affecting its inspection and maintenance. The covers of traditional guide equipment usually adopt a more complicated fixing method, such as screw fixing. Although this design ensures the sealing of the equipment to a certain extent, when inspection and maintenance are required, the process of removing the cover is cumbersome and easy to damage the equipment. It is difficult for visually impaired people to complete the removal of the cover independently. Once the equipment fails, professional personnel are required to repair it, which not only increases the maintenance cost and time cost, but may also cause the equipment to be unusable for a long time, seriously affecting the travel safety and convenience of visually impaired people.

[0005] 3. The camera of the guide device is one of its core components, used to monitor road conditions in real time and provide navigation information for the visually impaired. However, the camera angle adjustment function of existing guide devices is obviously insufficient. The camera installation position is fixed and cannot be flexibly adjusted according to the wearing posture of the visually impaired person and the actual road conditions, resulting in a limited monitoring range and an inability to fully and accurately capture road conditions. In addition, the operation button design of the device is not user-friendly and lacks an automatic reset function. During use, the visually impaired person needs to manually restore the button status after pressing the button, which increases the complexity of operation and easily affects the normal use of the equipment due to misoperation, reducing the user experience and reliability of the guide device.

[0006] In summary, existing guide devices have problems that need to be solved in terms of use and charging, inspection and maintenance, camera angle adjustment and ease of operation. These problems seriously affect the use effect of guide devices and the travel experience of visually impaired people. Therefore, developing an improved wearable barrier-free travel guide device and its use method to solve the above problems has important practical significance and broad application prospects.
