Description

Technical Field

[0001] This invention relates to an adjustment method and apparatus, and more particularly to a screen position adjustment method and apparatus that can adapt to the user's viewing posture. Prior Technology

[0002] Using computers to search for information, contact relatives and friends, and watch videos, and then displaying the results on the screen, has become a common way for modern people to use technology. However, users often focus on watching the screen content and neglect their own posture while using it, resulting in neck and shoulder pain or a turtle neck due to incorrect posture and eye position.

[0003] Currently, there are two ways to adjust the screen position: manual screen stand adjustment and automatic screen stand adjustment. Manual screen stand adjustment involves placing the screen on the screen stand, which allows the user to freely adjust the screen position according to their preferences. However, once adjusted, the screen remains in a fixed position. If the user experiences discomfort after prolonged use in an incorrect posture and with an unnatural gaze, they will have to manually adjust the screen stand again.

[0004] Automatic screen adjustment stands place the screen on a stand and automatically adjust the screen position based on the user's posture, height, or shoulder height using sensors. Although they have a dynamic automatic screen adjustment function, the main reason for incorrect posture is that the eyes are focused on looking at the screen content. Currently, automatic screen adjustment stands cannot automatically adjust the screen position based on the visual organs and the screen's horizontal line of sight.

[0005] In recent years, screen holders for adjusting screen position have been continuously developed and applied to reduce the discomfort of prolonged computer use in incorrect postures. While this is a good idea, the screen adjustment process has not been able to automatically adjust the screen based on the user's gaze. For example, manual screen holders allow users to freely adjust the screen position according to their preferences, but users still need to familiarize themselves with the mechanism and how to tighten the fasteners. Automatic screen holders, while dynamically adjusting the screen position according to the user's posture, still require time to detect and adjust the screen position each time they are used, and they have not been integrated with the deep learning technology that brings convenience. Therefore, this patent proposes a screen position adjustment method and device that automatically detects the visual organs and calculates their relative position to the screen using image recognition technology. Then, it automatically adjusts the screen position through edge computing. When the user's visual organs and the screen position meet the conditions, the screen position is automatically adjusted. In addition, users can manually save standard screen position modes.

[0006] However, existing screen stand devices have the drawback that adjustments must be made manually, which can lead to difficulties in making timely adjustments and requires familiarity with the device mechanism and the operation of the fasteners. Other manufacturers have developed automatic adjustment screen stand devices, but these devices still cannot adjust according to the relative position of the visual organs and the screen, and cannot store different user operating modes. This means that even if only two people take turns using the device, it still requires time-consuming adjustments from scratch.

[0007] In view of the above and other problems, there is a need to improve the prior art. Summary of the Invention

Implementation

[0030] To make the above and other objects, features and advantages of this invention more apparent and understandable, preferred embodiments of this invention are described below in detail with reference to the accompanying drawings. Symbols that are marked with the same symbols in different drawings are considered identical and their descriptions will be omitted.

[0031] Figure 1 is a perspective view of the screen position adjustment device for height and angle and the user in an embodiment of the present invention. Figure 6 is a perspective view of the screen position adjustment device for height, angle and distance and the user adjusting the height in an embodiment of the present invention. Figure 7 is a perspective view of the screen position adjustment device for height, angle and distance and the user adjusting the horizontal angle in an embodiment of the present invention. Please refer to Figures 1, 6, and 7. The screen position adjustment device of this embodiment is suitable for detecting and adjusting the position of a screen (M) based on detected values, so that the relative position with a visual organ (I) conforms to human ergonomics and has the expected health effect. The screen position adjustment device includes: a fixing unit (11), a height adjustment unit (12), an angle adjustment unit (13), a screen fixing unit (15), and an edge computing device (21). The fixing unit (11) is located at a fixed position (L), such as on a desktop; the height adjustment unit (12) is connected to the fixing unit (11) and has a first setting part (121), which can be electrically adjusted to a height (H) relative to the fixed position (L); the angle adjustment unit (13) is located on the first setting part (121), and its… It has a second setting part (131) which can be electrically adjusted to a horizontal angle (A) relative to the fixed position (L); a screen fixing unit (15) is connected to the second setting part (131) and the screen fixing unit (15) can be removably fixed to the screen (M); and an edge computing device (21) is provided on the screen fixing unit (15) and electrically connected to the angle adjustment unit (13) and the height adjustment unit (12). It can analyze and drive the height adjustment unit (12) and the angle adjustment unit (13) according to the presence of the visual organ (I) to adjust the screen (M) to the position corresponding to the visual organ (I) (i.e., the relative line of sight height and horizontal angle), or not adjust the position of the screen (M) and issue a message that it cannot be adjusted so that the user (U) can know.

[0032] Figure 2 is a perspective view of the screen position adjustment device for height, angle and distance of an embodiment of the present invention and the user. Figure 8 is a perspective view of the screen position adjustment device for height, angle and distance of an embodiment of the present invention adjusting the distance between the screen and the user. Please refer to Figures 2 and 8. The embodiment shown in Figure 2 is based on the embodiment in Figure 1 and further includes a distance adjustment unit (14). The distance adjustment unit (14) is disposed on the second setting part (131) and has a third setting part (141). The screen fixing unit (15) is connected to the third setting part (141) and can be electrically adjusted to a distance (D) relative to the fixed position (L). The edge computing device (21) is electrically connected to the distance adjustment unit (14) and can analyze and drive the height adjustment unit (12), the angle adjustment unit (13) and the distance adjustment unit (14) according to the presence of the visual organ (I) to adjust the screen (M) to the position corresponding to the visual organ (I) (i.e., the relative line height, horizontal angle and straight distance) or not adjust the position of the screen (M) and issue a message that cannot be adjusted to notify the user (U). For example, if any of the adjustment devices of the height adjustment unit (12) (H), the lateral angle of the angle adjustment unit (13) (A), or the straight distance (D) of the distance adjustment unit (14) malfunctions or the desired adjustment position exceeds the adjustable position limit, a message is sent to report the above reasons.

[0033] Figure 3 is a flowchart of a screen position adjustment method according to an embodiment of the present invention; Figure 4 is a side view of a screen position adjustment device adjusting the distance between the screen and the user and the height of the screen relative to the user's line of sight according to an embodiment of the present invention; and Figure 5 is a bottom view of a screen position adjustment device adjusting the shortest straight-line distance between the screen and the user and the horizontal angle between the screen and the user according to an embodiment of the present invention. Referring to Figures 3 to 5, the steps of the screen position adjustment method in this embodiment include: providing a screen position adjustment device to mount a screen and adjusting the relative position of the screen and a visual organ (S11); periodically triggering the visual organ with an edge computing device to perform an object detection algorithm (S21); the object detection algorithm detects the presence of the visual organ to activate and control the operation of the screen position adjustment device. The screen position adjustment device includes an angle detection algorithm and a height detection algorithm. The algorithm is used to detect the horizontal angle between the visual organ and the screen, and the height detection algorithm is used to detect the line-of-sight height between the visual organ and the screen (S31). The edge computing device continues to perform parallel processing of the calculations of several algorithms in the screen position adjustment device using distributed computing, so as to further determine whether the values ​​obtained by each algorithm meet their respective threshold values. If the threshold values ​​corresponding to each direction are met, the position of the screen is not adjusted. If there are any algorithm items that do not meet the threshold values, the values ​​are adjusted until they meet their respective threshold values ​​(S41).

[0034] Preferably, the screen position adjustment device further includes a distance detection algorithm to detect the straight-line distance between the visual organ and the screen (S32) to meet the distance adjustment between the screen and the visual organ within a certain range.

[0035] Please refer to Figures 2 and 3-5. The threshold values ​​in each example include height, angle, and distance thresholds. For example, the height threshold is the height of the user's (U) visual organ (I) plus a height tolerance range, such as ±15 cm; the angle threshold is the angle of the user's face facing forward plus a tolerance range, such as 30 degrees to the left or right; and the distance threshold is the tolerance range of the distance directly in front of the user's visual organ (I), such as 45-60 cm. When the object detection algorithm detects the presence of the visual organ (I), it then... When the edge computing device (21) calculates the relative visual height (Hh) between the visual organ and the screen, the relative lateral angle (Ah) between the visual organ and the screen, and the relative distance (Dh) between the visual organ and the screen, respectively, and they fall within the aforementioned height threshold, angle threshold, and distance threshold, the corresponding height adjustment unit (12), angle adjustment unit (13), and distance adjustment unit (14) of the screen position adjustment device will not operate. However, when any relative position exceeds the corresponding threshold, the corresponding adjustment unit will be activated to adjust the screen (M) to within the corresponding threshold.

[0036] Preferably, when there are algorithm items that do not meet the requirements and the values ​​cannot be adjusted to meet their respective threshold values, the edge computing device automatically sends a message to notify the user of the reason why the adjustment cannot be made. That is, if the height difference, angle difference, or distance difference between the user's visual organs and the screen exceeds the adjustable height (H), adjustable angle (A), or adjustable distance (D) range of the screen position adjustment device, the adjustment of that item is stopped, and the reason for stopping the adjustment is given, such as the screen position adjustment device malfunctioning or reaching or exceeding the adjustment position limit.

[0037] It's worth noting that when the object detection algorithm detects the absence of a visual organ, it enters a sleep mechanism algorithm, retaining only minimal detection operations, such as checking the presence of the visual organ and whether the sleep mechanism conditions are still met. Once these conditions are met, the object detection algorithm restarts. In other words, the object detection algorithm continuously detects the presence of the visual organ; if the user is in a gaze state, it determines the visual organ is present; if the user is not in a gaze state, it determines the visual organ is absent. When the visual organ is determined to be absent, no screen position adjustment is needed, but it still needs to continuously detect whether the user begins to gaze at the screen (M) to facilitate automatic screen position adjustment.

[0038] Please refer to Figures 2, 4 and 5. Preferably, the edge computing device (21) includes a microphone (211) and a voice recognition unit (212). The microphone (211) can capture the user's voice. The voice recognition unit (212) is electrically connected to the microphone (211) and can recognize voice commands from the user's voice. It can also control the corresponding height adjustment unit (12) to adjust the height of the screen (M), control the corresponding angle adjustment unit (13) to adjust the horizontal angle of the screen (M), and / or control the corresponding distance adjustment unit (14) to adjust the straight-line distance of the screen (M). Please refer to Figure 3. The screen position adjustment method of this invention may further include a voice control step (S42). The voice control step (S42) can capture the user's voice commands using the aforementioned edge computing device (21) and adjust the screen height, screen horizontal angle, and / or screen straight distance according to the recognized voice commands. For example, the aforementioned voice commands include correctly adjusting the screen (M) to a position suitable for the user's viewing, and also include the "move screen" command to move the screen (M) away from the user's line of sight. When the user calls (for example, the user gives the screen position adjustment device a voice command to "use screen"), the screen (M) will first return to the user's front and then automatically adjust the height, angle, and distance.

[0039] Preferably, the screen position adjustment device can store multiple sets of adjustment parameters to facilitate quick recall of these parameters for users who have already made adjustments, enabling rapid and customized automatic adjustments. In other words, the object detection algorithm includes storing the adjustment parameters of the screen position adjustment device for each use and providing the device with the ability to recall settings based on these stored parameters. Alternatively, it can incorporate facial recognition of the user's physiological characteristics to automatically recall the corresponding settings.

[0040] Please refer to Figures 6, 7, and 8. If the user maintains the same height but moves to the left, the angle detection algorithm detects that the relative lateral angle (Ah) between the user's visual organs and the screen exceeds the angle threshold range (as described above). However, the height detection algorithm detects that the relative visual height (Hh) between the user's visual organs and the screen does not exceed the height threshold range, and the distance detection algorithm detects that the relative distance (Dh) between the user's visual organs and the screen does not exceed the distance threshold range. Therefore, the screen position adjustment device will only adjust the screen's lateral angle until the relative lateral angle (Ah) between the visual organs and the screen enters the angle threshold range. Through the above process, the screen can be automatically adjusted to a standard position, allowing the user to maintain a healthy and comfortable posture when aligned with this standard position. When a user cannot maintain the posture for an extended period of time, causing their visual organs to deviate slightly from the horizontal angle of the screen, the eye level of the screen, or the straight-line distance from the screen to a value exceeding a threshold, the edge computing device drives the screen position adjustment device to make adjustments (i.e., adjust the screen position) until each value meets the threshold value, thereby automatically adjusting the screen to a more suitable position corresponding to the visual organs.

[0041] In summary, this invention utilizes a controllable screen position adjustment device fixed in a specific location such as a desktop. An edge computing device periodically triggers the presence of the visual organ; if the visual organ is not present, there is no need to adjust the angle, height, or distance between the screen and the visual organ. Furthermore, the adjustment principle of this invention is independent of screen size, thus it is not affected by screen size recognition. This invention employs deep learning image recognition technology to automatically adjust the screen position, reducing bottlenecks in mechanism adjustment and fastening operations, and preventing physical discomfort caused by poor posture when using a computer.
