Technical Field

[0001] This utility model relates to the field of smart wearable device technology, and in particular to a wearable device. Background Technology

[0002] Despite the existence of various assistive devices for the blind on the market, despite the continuous development of technology, these devices generally suffer from problems such as fragmented processing of sensory information, insufficient interactive intelligence, and low accessibility. For example, traditional assistive devices rely on a single sensory method (such as sound or touch), making it difficult for users to obtain sufficient and comprehensive information in complex environments. Furthermore, most existing devices cannot effectively adapt to different usage scenarios, such as failing to avoid obstacles in dynamic environments in real time, or failing to provide sufficient assistance in daily life.

[0003] Existing assistive devices for the blind, such as guide canes and guide dogs, cannot allow users to observe the environment from the height and direction of their eyes, and cannot accurately match environmental information with directions, thus failing to provide better assistance to the blind. Utility Model Content

[0004] To address the aforementioned problems, this utility model provides a wearable device that, by wearing an assistive device on the eyes, enables the user to obtain environmental information in actual direction, specifically including:

[0005] A wearable device includes a first housing and a second housing;

[0006] The first housing and the second housing are detachable. When the first housing and the second housing are fastened together, the first housing and the second housing form an eyeglasses-style case, and the eyeglasses-style case is provided with storage space.

[0043] Existing assistive devices for the blind are mostly in the form of canes, where the actual visual direction is not closely related to the direction perceived by the wearer. Therefore, this application provides a wearable device that is not only lightweight and hand-held, but also comfortable to wear. Furthermore, it can simulate the human eye, transmitting environmental factors in the visual direction to the wearer, enabling the wearer to align their orientation with the environment in that orientation. The specific details are as follows:

[0044] like Figures 1 to 7As shown, a wearable device includes a first housing and a second housing; the first housing and the second housing are detachable, and when the first housing and the second housing are fastened together, the first housing and the second housing form an eyeglass-style case, and the eyeglass-style case has a storage space inside; the second housing has buckles on both sides for installing elastic bands; the first housing has an oblong groove for holding a binocular camera; the second housing has a mounting bracket on the side facing the first housing, the bracket being positioned corresponding to the oblong groove, and the mounting bracket is used to install the binocular camera; the bottom middle section of the first housing and the bottom middle section of the second housing have corresponding recesses, the recesses being ergonomically designed and adapted to fit the bridge of the nose.

[0045] The mounting bracket includes a support pile and a fixing plate. One end of the support pile is vertically installed on the side wall of the second housing, and the other end of the support pile is installed with the fixing plate. The support pile and the fixing plate are arranged perpendicularly. When the first housing and the second housing are fastened together, the oval groove of the first housing is adapted to the position of the fixing plate. The binocular camera is installed on the fixing plate (the fixing plate faces the surface of the first housing) and the binocular camera is placed in the oval groove. The shape and size of the oval groove are exactly the same as those of the fixing plate and are adapted to it.

[0046] In one specific embodiment, the first housing is rectangular, and the oblong through groove is located on the surface with the largest surface area of ​​the first housing. An opening is located opposite the surface of the oblong through groove. Four mounting posts are provided on the inner wall of the surface with the largest surface area of ​​the first housing. The mounting posts are perpendicular to the inner wall and have threads on their inner walls. The four mounting posts are distributed at four right angles on the surface of the first housing. The second housing has four through holes, and the positions of the mounting holes correspond one-to-one with the positions of the mounting posts. When the first housing and the second housing are fastened together, bolts are connected to the mounting posts through the mounting holes to fix the first housing and the second housing together. The second housing is rectangular, and the surface with the largest surface area of ​​the second housing faces away from the surface with the largest surface area of ​​the first housing. The surface of the second housing that abuts against the first housing is open, and the opening of the second housing is contained within the opening of the first housing.

[0047] In addition, the volume of the first shell is slightly smaller than that of the second shell, making the structure lighter and less bulky to wear, without affecting the wearing experience.

[0048] In one specific implementation, the first housing has a square side opening structure. The opening of the first housing is for docking with the second opening. An oval through groove is set on the largest surface of the first housing. A recess (corresponding to the nose bridge recess) is set in the middle of the oval through groove. The oval channel is used to carry a binocular camera. The binocular camera can be an Intel D415 depth camera, which supports the acquisition of conventional images and depth maps. It is connected to the processor (which is generally the main controller) via a USB interface and is responsible for capturing environmental images and spatial depth information.

[0049] To prevent this device from being easily bumped or knocked, all edges of the overall outer casing of this device have been rounded, and the four corners of the first casing and the second casing are rounded.

[0050] In one specific embodiment, the second housing also has a side-opening structure, except that the opening of the first housing is designed to mate with the opening of the second housing. When the two are installed, the boundary between the opening of the first housing and the opening of the second housing forms a single unit with internal storage space. Additionally, two opposite outer walls of the second housing are provided with clips, each clip including a mounting plate and a locking hole. The clips are an integral structure, with the mounting plate fixedly installed on the side wall of the second housing. From the first housing to the second housing, the locking holes of the clips protrude from the surface of the second housing and extend towards it, facilitating assembly via an elastic band when wearing the wearable device.

[0051] All boundary lines of the second and first housings are rounded, including the recessed area that adapts to the bridge of the nose, thus adhering to ergonomic comfort. Mounting holes are provided on the surface of the largest area of ​​the second housing to correspond to mounting posts. When the first and second housings are engaged, bolts are inserted through the mounting holes into the mounting posts to secure the first and second housings.

[0052] In one specific implementation, the storage space includes a microphone, a power supply, a main controller, and a Wi-Fi module. The binocular camera, the main controller, and the Wi-Fi module are each connected to the power supply. The microphone supports receiving commands and is connected to the main controller. Based on the commands, the output audio volume can be adjusted, or the desired image information can be repeated. Furthermore, the main controller's built-in program is existing technology. For example, the main controller supports an image-to-audio conversion program to achieve audio-visual interaction, converting images into sound (SST technology), which is existing technology. It can also be equipped with an intelligent obstacle avoidance program, such as the YOLOv8 intelligent obstacle avoidance program. Furthermore, LLM intelligent interaction and emotion analysis can be programmed into the main controller as needed to provide assistance to the blind.

[0053] The main controller is connected to the binocular camera; the main controller supports signal connection with the terminal device via a Wi-Fi module; the microphone supports collecting sound information of the current scene and transmitting the sound information of the current scene to the main controller. The device also includes an audio output unit, which is a stereo headset; a Bluetooth module is installed in the storage space, and the stereo headset is connected to the main controller via the Bluetooth module; when the main controller outputs image and sound information as audio information, the audio information is output through the stereo headset.

[0054] The first and second housings can be fabricated using 3D printing equipment.

[0055] This device enables blind people to experience visual comfort. Fitted around the patient's eyes, the device's binocular cameras record environmental information as the patient rotates their head. This allows the patient to align the direction of their eyes with the surrounding environment, better simulating the visual environment and thus providing greater assistance to the blind. Furthermore, the device is lightweight and easy to wear. The bottom of the first and second housings features recesses that conform to the patient's nose, enhancing comfort. The edges of the first and second housings are rounded to reduce scratches to others or objects. The device is also detachable for maintenance. Additionally, the housings can be 3D printed, allowing for adjustments to the overall dimensions of the first and second housings for individuals with specific facial features (larger or smaller heads).
