2. Description of the Related Art Recently, users of various products tend to prefer products that not only provide physical convenience but also satisfy the user's sensitivity. One of the easiest ways to do this is to pursue the variety and variety of product designs. However, as a more active method, the function of the product can be automatically adjusted according to the current physiological state of the user. Here, the physiological state includes a physical state and a psychological state.

[0003] In modern society, not only business hours but also leisure time, the time for viewing a display device, for example, a television or a monitor, is increasing. Nevertheless, a typical display device has its use environment set regardless of the physiological state of each user. Of course, the user adjusts the use environment to the optimum conditions for himself, but the accuracy and precision are limited. It is the general view that the display device is not good for the user's health.

[0004]

SUMMARY OF THE INVENTION Accordingly, an object of the present invention is to provide a display system which can protect the user's health and improve convenience.

[0005]

According to the present invention, there is provided an automatic adjustment display system including a display device, a physiological controller, and a variable adjustment unit. The display device processes an externally input image signal according to an adjustable display variable and displays an image. The physiological controller generates a physiological control signal according to a physiological state of the user. The variable adjuster adjusts the display variable according to a display state of the display device and a physiological control signal from the physiological controller.

According to the automatic adjustment display system of the present invention, since the display device is automatically controlled by the physiological controller and the variable control unit, the display state can be automatically adjusted according to the physiological state of the user. Thereby, the health of the user is protected, and the convenience can be improved.

Preferably, the physiological controller includes a physiological state detector, a detection level calculator, an adjustment value calculator, and a signal transmitter. The physiological condition detector generates a detection signal corresponding to the physiological condition of the user. The detection level calculator generates a data signal corresponding to the level of the detection signal from the physiological condition detector. The adjustment value calculator processes the data signal from the detection level calculator to generate an adjustment signal for the display variable. The signal transmission unit transmits the physiological control signal corresponding to the adjustment value signal from the adjustment value calculation unit to the variable adjustment unit.

[0008]

Preferred embodiments of the present invention will be described below in detail with reference to the accompanying drawings.

Referring to FIG. 1, an automatic adjusting display system according to the present invention comprises a display device 3 provided with a fragrance device 4, a remote controller 5 provided with a physiological controller 1, an audio device 6, and A variable adjustment unit 2 is included.

The display device 3 displays an image by processing an externally input image signal according to an adjustable display variable. The remote controller 5 directly controls the display state of the display device 3 and the sound generation state of the sound device 6 by a user's operation. The physiological controller 1 provided in the remote controller 5 generates a physiological control signal according to the physiological state of the user of the display device 3.

The variable control unit 2 controls the display state of the display device 3 and a display variable of the display device 3 according to a physiological control signal from the physiological controller 1.
The sound variable of the sound device 6 and the scent variable of the scent device 4 are adjusted. The display variables of the display device 3 determine the output levels of hue, saturation, brightness, brightness and contrast of the entire screen.

The variable adjuster 2 operates as follows. If it is determined that the user is nervous, the display variables are adjusted to provide a relatively soft visual and audible feeling. At this time, in order to obtain a soft hearing, the amplitude of the low frequency is relatively increased. On the other hand, when it is determined that the user is in a sleepy state, a relatively high luminance is applied so that the user can perceive. Further, the amplitude of the high frequency and the output level of the fragrance device are further increased to stimulate the sense of hearing and smell. As a result, the user can confirm that he or she is in a sleepy state and take a desired action.

Referring to FIGS. 2 and 3, the physiological controller 1 is provided in a general remote controller 5. Here, the physiological condition detecting unit 11 is provided at a portion where the user's finger is most frequently contacted outside the remote controller. The physiological controller 1 includes a physiological state detector 11, a detection level calculator 12, and an adjustment value calculator.
13 and a signal transmission unit 14.

The physiological condition detector 11 generates a detection signal corresponding to the physiological condition of the user.

The detection level calculation unit 12 includes a physiological state detection unit 11
And generates a data signal corresponding to the level of the detection signal.

The adjustment value calculation unit 13 processes the data signal from the detection level calculation unit 12, and displays the data signal (3 in FIG. 1).
Display variables of the acoustic device (6 in FIG. 1),
And generating an adjustment value signal for the odorant variable of the odorant device (4 in FIG. 1).

The signal transmission unit 14 transmits a physiological control signal corresponding to the adjustment value signal from the adjustment value calculation unit 13 to the variable adjustment unit (2 in FIG. 1).

The detection signal from the physiological condition detector 11 is a signal corresponding to at least one of the electrical conductivity of the skin, blood pressure, pulse, brain wave, heart rate and respiratory cycle.
The electrical conductivity, blood pressure and pulse of the skin are proportional to the user's tension. The amplitude of alpha waves as brain waves is inversely proportional to the degree of user tension. The difference between the maximum heart rate and the minimum heart rate for a certain period of time is proportional to the user's tension. This difference in heart rate can be easily calculated using FFT (Fast Fourier Transform). The difference between the maximum respiration cycle and the minimum respiration cycle for a certain period of time is proportional to the user's tension.

On the other hand, when the display device (3 in FIG. 1) is a personal computer, the physiological controller 1 is provided on a keyboard of the personal computer. At this time, the physiological condition detecting unit 11 is provided for a key to which the user's finger most frequently contacts among the keys of the keyboard. For example, the middle finger and the index finger touch frequently. "
K "," L "," D "and" S "are provided on keys, etc. In addition, the physiological condition detecting unit 11 may be provided on a mouse of a personal computer.
When the panel type includes a user input unit, the physiological condition detecting unit 11 may be provided in the display device 3 in some cases.

[0020]

As described above, according to the automatic adjustment display system according to the present invention, the display device, the sound device, and the fragrance device are automatically controlled by the physiological controller and the variable control unit. The display, sound and scenting state can be automatically adjusted according to the physiological state of the subject. As a result, the health of the user is protected and convenience can be improved.
