Description

　Automatic lighting control and anti-sleeping stand with visual fatigue measurement}

This invention is related to the automatic lighting adjustment stand, and it is equipped with a device to measure the degree of visual fatigue and drowsiness together with the electric stand manual control unit, and prevents the change of lighting or the prevention of drowsiness to mitigate the visual fatigue according to the user's purpose. It is about how to use the system for “automatically use” functions.

An electric stand is a tool that is often used in cases such as studying or reading. As a result, the existing stand is well-equipped as a mechanism that provides bright lighting, but it does its job well, but it lacks the ability to provide the necessary brightness by tailoring the intensity of the lighting or brightness. Depending on the user's environment or usage, the required illumination or color temperature may differ, and the brightness that should be provided according to the user's fatigue may not be provided according to the different brightness, and the user may feel fatigue when using the product for a long time. And, in a situation where the user is “sleepy” and in a situation where there is no change, it is impossible to return the user to the “required state” for the operation. In this regard, this technology attempts to solve the problem by measuring the degree of fatigue and drowsiness at the time of vision to provide “light” in a suitable “stay” condition, or by providing a method to prevent “sleepiness”.

In order to solve the above problems, in the present invention, in addition to a basic stand capable of manually adjusting brightness, a cpu for comparing information with an infrared and motion-sensing camera is mounted, and the user's eyeball and face temperature information is captured to determine the user's real-time status. Provide adequate lighting.

In order to achieve the above-mentioned purpose, the “lighting” change through the “visual” fatigue measurement and the “prevention of drowsiness” “electric stand” according to the present invention are controlled by the power supply, manual brightness control, mode selector and lighting position control for light and operation providing light. The above object is achieved by configuring a rotating part, a length adjusting part, a photographing part for photographing user's eye and face information, and a data processing part for lighting control based on the photographing information.

As described above, this technology ensures that the user can receive illumination from an appropriate position through the “position” adjustment of the stand, and can be used to measure the user's “eye blink” and “face temperature” measurements when using the light. It has the effect of inducing “enhancement of concentration” and “preventing sleepiness” through the “functionality” that can adjust the lighting by measuring the “state of fatigue” and “sleepiness” by positioning.

FIG. 1 is a block diagram showing a method of changing illumination by measuring visual fatigue through data of the eye blink measurement unit and the face temperature measurement unit of the present technology,
Figure 2 is a block diagram showing a method of measuring the state of drowsiness through the data of the eye blink measurement unit and the facial temperature measurement unit of the present technology and applying a sleepiness prevention system,

The role of the stand described in the present invention is to measure a user's eye fatigue and drowsiness in real time and to perform appropriate lighting output. To this end, the stand comprises a photographing device that measures the user's eye and face information, and a data processing device that outputs illumination based on the measured information.

In this case, as an objective index for measuring the user's eye fatigue, a method of measuring the eye and face temperature information of the normal user and comparing the real-time measurement information with the normal measurement information is used.

Hereinafter, embodiments of the present invention will be described with reference to the accompanying drawings.

Fig. 1 is a method of constructing data that changes the illumination through “visual” fatigue measurement in this technology. This is composed of the "back part 100" of FIG. 3, "the first shooting part 400", "the second shooting part 410", and the "data processing part 600".

In the above-mentioned “first photographing unit 400”, “a user's “eye” is measured.

It consists of a “super high speed” camera.

In the above-mentioned “first photographing unit 400”, “information” about the “state” of the user's “eyeball” is measured and input.

The second photographing unit 410 measures the temperature of the user's face.

It consists of a “thermal image” camera with “infrared” capability.

In the above-described second photographing unit 410, information about “surface” temperature of the user's “face” is measured and input.

The above-described “data processing unit 600” plays a role of “adjusting the lighting” based on the “data”.

The above-described data processing unit receives and stores the data of the first recording unit 400 and the second recording unit 410, and then stores and receives the data once again after a certain period of time, and then compares it with the previously stored data and compares it with the previously stored data. Determines and plays the role of adjusting the lighting in real time according to the change of the inputted value.

Based on the above-described configuration, the principle of outputting predetermined lighting information to the back using the mechanism of FIG. 1 by analyzing and using normal user information and real-time user information on the stand is used.

Fig. 2 is a method of structuring the data representing the system that measures the degree of drowsiness in this technology and prevents drowsiness through illumination. This is composed of the “back part 100” of FIG. 3, “first photographing part 400”, and “data processing part 600”.

The above-mentioned “first photographing unit 400” measures the “eye” of the user and “motion of the face”.

The above-mentioned “first photographing unit 400” measures “the number of times the user's eyes are closed and the range of the movement of the face”.

The above-described “data processing unit 600” plays a role of “adjusting the lighting” on the basis of “data”.

The above-mentioned “data processing unit 600” determines whether the user is “sleepy” by determining whether the “face movement” of the user has shifted out of the “set” range “on the basis of the “blinking data” passed by the measurement unit, or whether the number of “closed eyes” for a certain time exceeds the “standard” When it is determined that it is drowsy, it plays the role of “light” to blink.

The above-mentioned “lighting part 100” plays a role of providing “lighting” and plays a role of blinking “lighting” when the “lighting” state is determined through the “signal” signal from the data processing unit 600 to “exit” the user's “sleeping” state.
