[0034] In order to make the purpose, technical solutions and advantages of the application clearer, the application will be further described in detail below with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are only used to explain the application and not to limit the application.

[0035] Referring to Figure 1 The application provides a method for improving learning efficiency based on table lamp projection, which comprises steps S1-S3, specifically:

[0036] S1, when the table lamp is turned on, start recording the learning time.

[0037] Specifically, for step S1, usually the user will turn on the desk lamp when starting to learn, so taking the moment when the desk lamp is turned on as the starting moment of recording the learning time is in line with the usual learning habit. The recorded learning time is used to detect the user's real-time learning state for timing, and the desk lamp projection mode is adjusted according to the learning state.

[0038] S2, when the learning time reaches the first preset time, the user's learning state is detected, and it is judged whether the user has the characteristics of learning fatigue and / or incorrect continuous sitting posture.

[0039] Specifically, for step S2, the first preset time can be set with reference to the length of the current learning task and the current state of the user. For example, from 8 am to 12 pm is a learning time, when the user is currently full of learning energy or has good learning habits in general, the first preset time can be set to every 1 hour to detect the user's learning state within 10 minutes; when the user is currently more sleepy or has often incorrect learning posture in general, the first preset time can be set to every half hour to detect the user's learning state within 5 minutes. If the learning time is from 9 pm to 10 pm, the first preset time can be set to every 10 minutes or 30 minutes to detect the user's learning state within 3 minutes. A camera can be provided on the desk lamp to determine whether the user has the characteristics of learning fatigue or incorrect continuous sitting posture. The judgment method of fatigue can be to detect whether the user's closed-eye time exceeds the preset time, and the number of eye blinks within the preset time. The judgment method of incorrect continuous sitting posture can be to collect the image of the user's sitting posture, compare the image of the user's sitting posture with the standard sitting posture, and determine that the user's sitting posture is incorrect when the deflection angle exceeds the preset threshold.

[0040] S3, after determining that the characteristics appear, a corresponding projection mode is executed to adjust the direction and position of the projection.

[0041] Specifically, for step S3, when the user has the characteristics of learning fatigue or incorrect continuous sitting posture, the projection mode is adjusted according to the actual situation. By intelligently adjusting the direction and position of the projection, the user's learning posture and learning state are guided to improve, thereby improving the learning efficiency.

[0042] In one embodiment, the step S3 of executing a corresponding projection mode to adjust the direction and position of the projection after determining that the characteristics appear includes:

[0043] S301, scanning the scene in the environment to obtain a plurality of regions suitable for projection in the scene, extracting a suitable projection region to obtain at least one projection region, and selecting a suitable projection region for projection.

[0044] Specifically, for step S301, when the user appears to be learning fatigue or the situation of continuous incorrect sitting posture, the projection position needs to be adjusted so that the user adjusts the learning state accordingly. Before adjusting the projection position, the scene in the environment suitable for projection is obtained, and the suitable projection area is extracted from the flatness, area, color, light reflection characteristics, and distance suitable for projection. The selection range is provided for subsequent projection movement, at least one projection area is obtained, and the suitable projection area is selected for projection (for example, in an embodiment, a comprehensive evaluation can be performed according to the above-mentioned parameters, and after priority ranking, the projection is selected).

[0045] In one embodiment, after the above-mentioned steps of scanning the scene in the environment, obtaining the scene in the environment suitable for projection, extracting the suitable projection area, obtaining at least one projection area, and selecting the suitable projection area for projection, step S301 includes:

[0046] S302, when the projection area is above the current projection direction, the projection area is set as the first projection area, the user's head is taken as the center, the horizontal plane where the eyes are located is taken as the reference, and the projection is moved upward in the longitudinal direction to the first projection area.

[0047] Specifically, for step S302, as the first adjustment of the projection area, the adjustment range is small based on the original projection area, and the projection is moved upward in the longitudinal direction of the original projection area combined with the projection scene to guide the user to look up or raise the eyes, adjust the sitting posture and learning state. It can be understood that appropriate head lifting is helpful for body posture adjustment, and at the same time changes the eye level environment and the brightness of the line of sight, and further fine-tunes the spirit and mood. Therefore, in the state of the initial adjustment of the projection area, the head lifting guide with a small adjustment range but improving the sitting posture and / or learning state is the preferred strategy. (Especially for the projection on the desktop, the user originally needs to learn with a low head.)

[0048] In one embodiment, after the above-mentioned steps of when the projection area is above the current projection direction, the projection area is set as the first projection area, the user's head is taken as the center, the horizontal plane where the eyes are located is taken as the reference, and the projection is moved upward in the longitudinal direction to the first projection area, step S302 includes:

[0049] S303, after the projection is displayed in the first projection area for a second preset time, when it is detected that the user's learning state still has the characteristics of fatigue and / or continuous incorrect sitting posture, the turning angle of the first projection area and other projection areas is calculated.

[0050] S304, selecting a second projection area corresponding to a steering angle based on the fatigue degree of the user, wherein different fatigue degrees correspond to different steering angles.

[0051] Specifically, for steps S303 and S304, the second preset time is a specified time after the projection area is adjusted to the first projection area. If the user's learning is still fatigued or the incorrect sitting posture state continues within the second preset time, the adjustment of the first projection area is not enough to improve the current learning state of the user. Therefore, the adjustment range needs to be increased. First, the appropriate projection area in other directions based on the first projection area needs to be obtained, and the steering angle of each appropriate projection area relative to the first projection area needs to be calculated. The greater the fatigue degree of the user, the greater the steering angle of the appropriate projection area selected corresponding to the steering angle, which is set as the second projection area. The greater the steering angle, the greater the change of the environmental characteristics, which can effectively stimulate the sensory changes of the user. At the same time, the body posture of the user changes dynamically corresponding to the projection area, which comprehensively adjusts the attention and spirit of the user to stimulate the attention and spirit of the user, adjusts the learning state or the sitting posture state, and thus improves the learning efficiency.

[0052] In one embodiment, after the step S304 of selecting a second projection area corresponding to a steering angle based on the fatigue degree of the user, the following steps are included:

[0053] S305, detecting the background color of the second projection area and adjusting the color of the projection itself.

[0054] Specifically, for step S305, since the adjustment range of the second projection area is larger than that of the initial projection area, the background color of the second projection area is more likely to change. Therefore, the background color of the second projection area needs to be detected, and the color of the projection itself needs to be adjusted to achieve the appropriate projection viewing effect of the second projection area. For example, in a white background projection area, the projection color is adjusted to be dark; in a dark projection area, the projection color is adjusted to be light.

[0055] In one embodiment, after the step S304 of selecting a second projection area corresponding to a steering angle based on the fatigue degree of the user, the following steps are included:

[0056] S306, after a third preset time of displaying the projection in the second projection area, if it is detected that the learning state of the user is still fatigued, prompting whether to project the ceiling.

[0057] S307, after detecting the instruction of converting the projection area into the ceiling, projecting the ceiling.

[0058] Specifically, for steps S306 and S307, when the user is still in the fatigue state after two adjustments of the projection area, increasing the adjustment range of the projection area should have little effect on improving the user's fatigue, and therefore the user is prompted to confirm whether the projection area needs to be converted to the ceiling. If the user confirms the conversion of the projection area, the projection area is converted to the ceiling. This facilitates the user to relax the body fatigue in a lying position, thereby concentrating on watching the projection learning and improving the learning efficiency.

[0059] In one embodiment, after the step S307 of projecting the ceiling, after detecting the instruction of converting the projection area to the ceiling, the method comprises:

[0060] S308, after the fourth preset time of projecting the ceiling, when it is detected that the user is still in the fatigue state, prompting whether to continue learning;

[0061] S309, if it is detected that the user selects to continue learning, detecting the learning content, and if the learning content is suitable for being played by sound, prompting whether to close the projection and output the learning content by broadcasting.

[0062] Specifically, for steps S308 and S309, after the fourth preset time of projecting the ceiling, when it is detected that the user is still in the fatigue state, the state of the user is not suitable for efficient learning, and therefore the user is prompted whether to continue learning. If the user selects to end the learning, the desk lamp projection is closed. If the user selects to continue learning, the learning content is detected, and if the learning content is suitable for being played by sound, such as reading learning or listening to lecture content, it is prompted whether to close the projection and output the learning content by broadcasting, so as to help the user improve the learning efficiency by changing the output mode of the learning content. If the learning content is only suitable for being output by projection, the projection playing can be paused for a period of time for the user to relax or freely move before continuing the learning. The pause time can be set by the user. The user can also select not to pause the projection, customize the selection of the appropriate projection area, or continue the learning by projecting the ceiling.

[0063] Reference Figure 2 is a structure block diagram of a device for improving learning efficiency based on desk lamp projection in an embodiment of the present application. The device comprises:

[0064] The time recording module 100 is configured to start recording the learning time when the desk lamp is turned on.

[0065] The state detection module 200 is configured to detect the learning state of the user when the learning time reaches the first preset time, and determine whether the user has the characteristics of learning fatigue and / or incorrect sustained sitting posture.

[0066] The projection control module 300 is configured to execute the corresponding projection mode to adjust the direction and position of the projection after determining that the characteristics appear.

[0067] Specifically, for the time recording module 100, generally, the user will turn on the desk lamp when starting to learn, so that the moment when the desk lamp is turned on is the starting moment of recording the learning time, which conforms to the usual learning habit. The recorded learning time is used to detect the user's real-time learning state for timing, and the desk lamp projection mode is adjusted according to the learning state.

[0068] Specifically, for the target sound control module 200, the first preset time can be set with reference to the length of the current learning task and the current state of the user. For example, from 8 am to 12 pm is a learning time, when the user is currently full of learning energy or has good learning habits in general, the first preset time can be set as every 1 hour to detect the learning state of the user within 10 minutes; when the user is currently more sleepy or has often incorrect learning posture in general, the first preset time can be set as every half hour to detect the learning state of the user within 5 minutes. If the learning time is from 9 pm to 10 pm, the first preset time can be set as every 10 minutes or 30 minutes to detect the learning state of the user within 3 minutes. A camera can be provided on the desk lamp to determine whether the user has the characteristics of learning fatigue or persistent incorrect posture. The judgment method of fatigue can be to detect whether the user's closed-eye time exceeds the preset time, the number of times the user blinks within the preset time, etc. The judgment method of persistent incorrect posture can be to collect the image of the user's posture, compare the image of the user's posture with the standard posture, and determine that the user's posture is incorrect when the deflection angle exceeds the preset threshold.

[0069] Specifically, for the projection control module 300, when the user has learning fatigue or persistent incorrect posture, the projection mode is adjusted according to the actual situation. By intelligently adjusting the direction and position of the projection, the user's learning posture and learning state are guided to improve, thereby improving the learning efficiency.

[0070] In one embodiment, the above-mentioned device for improving learning efficiency based on desk lamp projection further comprises:

[0071] The projection environment detection module is configured to scan the scene in the environment, obtain a plurality of regions suitable for projection in the scene, extract a suitable projection region, obtain at least one projection region, and select a suitable projection region for projection.

[0072] Specifically, for the projection environment detection module, when the user appears learning fatigue or continues to sit in an incorrect position, the projection position needs to be adjusted so that the user adjusts the learning state accordingly. Before adjusting the projection position, multiple regions suitable for projection in the scene need to be obtained, and the suitable regions are extracted by comprehensively considering flatness, area, color, light reflection characteristics, and distance suitable for projection. To provide a selection range for subsequent projection movement, at least one projection region is obtained, and a suitable projection region is selected for projection (for example, in an embodiment, a comprehensive evaluation can be performed according to the above-mentioned multiple parameters, and after priority ranking, the optimal projection is selected).

[0073] In an embodiment, the above-mentioned device for improving learning efficiency based on table lamp projection further comprises:

[0074] The first projection module is configured to, when the projection region is above the current projection direction, set the projection region as a first projection region, and in the longitudinal direction, move the projection upward to the first projection region with the user's head as the center and the horizontal plane where the eyes are located as the reference.

[0075] Specifically, for the first projection module, as the first adjustment of the projection region, the adjustment range is small based on the original projection region, and the projection is moved upward in the longitudinal direction of the original projection region in combination with the projection scene to guide the user to look up or raise the eyes, adjust the sitting posture and the learning state. It can be understood that appropriate head lifting is helpful for body posture adjustment, and at the same time changes the eye level environment and the brightness of the line of sight, and further fine-tunes the mental state. Therefore, in the state of initial adjustment of the projection region, the head lifting guide with a small adjustment range but capable of improving the sitting posture and / or the learning state is the preferred strategy. (Especially for the case where the user needs to look down to learn originally when the projection is on the desktop.)

[0076] In an embodiment, the above-mentioned device for improving learning efficiency based on table lamp projection further comprises:

[0077] The second projection module is configured to, after the projection is displayed in the first projection region for a second preset time, when it is detected that the user's learning state still has the characteristics of fatigue and / or continuous incorrect sitting posture, calculate the turning angle of the first projection region and other projection regions; based on the user's fatigue degree, select a second projection region corresponding to the turning angle for projection, wherein different fatigue degrees correspond to different turning angles.

[0078] Specifically, for the second projection module, the second preset time is a specified time after the projection area is adjusted to the first projection area. If the user's learning is still in a state of fatigue or incorrect sitting posture within the second preset time, the adjustment of the first projection area is not enough to improve the user's current learning state. Therefore, the adjustment range needs to be increased. First, the appropriate projection area in other directions based on the first projection area is obtained, and the turning angle of each appropriate projection area relative to the first projection area is calculated. The greater the fatigue degree of the user, the greater the turning angle of the appropriate projection area selected, which is set as the second projection area. The greater the turning angle, the greater the change of the environmental characteristics, which can effectively stimulate the sensory changes of the user. At the same time, the user's body posture changes dynamically with the projection area, which comprehensively adjusts the user's attention and spirit, adjusts the learning state or sitting posture, and thus improves the learning efficiency.

[0079] In one embodiment, the device for improving learning efficiency based on desk lamp projection described above further comprises:

[0080] The projection color adjustment module is configured to detect the base color of the second projection area and adjust the color of the projection itself.

[0081] Specifically, for the projection color adjustment module, since the adjustment range of the second projection area is larger than that of the initial projection area, the base color of the second projection area is more likely to change. Therefore, the base color of the second projection area needs to be detected, and the color of the projection itself needs to be adjusted to achieve the appropriate projection viewing effect of the second projection area. For example, in a white background projection area, the projection color is adjusted to dark; in a dark projection area, the projection color is adjusted to light.

[0082] In one embodiment, the device for improving learning efficiency based on desk lamp projection described above further comprises:

[0083] The third projection module is configured to, after the third preset time of displaying the projection in the second projection area, prompt whether to project the ceiling when detecting that the user's learning state is still in a state of fatigue, and project the ceiling after detecting an instruction to convert the projection area into the ceiling.

[0084] Specifically, for the third projection module, when the user is still in a state of fatigue after two adjustments of the projection area, increasing the adjustment range of the projection area should not have much effect on improving the user's fatigue. Therefore, the user is prompted to confirm whether to convert the projection area to the ceiling. If the user confirms to convert the projection area, the projection area is converted into the ceiling. This facilitates the user to relax the body fatigue in a lying position, thereby concentrating on watching the projection learning, and thus improving the learning efficiency.

[0085] In one embodiment, the device for improving learning efficiency based on desk lamp projection described above further comprises:

[0086] The learning mode adjustment module prompts whether to continue learning when detecting that the user is still in the fatigue state after the fourth preset time of projecting the ceiling. If it is detected that the user selects to continue learning, the learning content is detected, and if the learning content is suitable for being played in sound, the learning content is prompted whether to be closed for projection and output using broadcasting.

[0087] Specifically, for the learning mode adjustment module, when the projection area is converted to the ceiling for the fourth preset time, it is detected that the user is still in the fatigue state, at this time, the state of the user is not suitable for efficient learning, and therefore the user is prompted whether to continue learning. If the user selects to end learning, the desk lamp projection is closed. If the user selects to continue learning, the learning content is detected, and if the learning content is suitable for being played in sound, for example, reading learning or listening to lecture content, the learning content is prompted whether to be closed for projection and output using broadcasting, so as to help the user improve learning efficiency by changing the output mode of the learning content. If the learning content is only suitable for being output in the projection mode, the projection play can be paused to allow the user to relax or freely move for a period of time and then continue learning. The pause time can be set by the user. The user can also select not to pause the projection, customize to select a suitable projection area, or continue to project the ceiling for learning.
