The headset type remote controller according to an embodiment of the present invention includes a speaker function and can provide a remote control function.

When the headset is mounted on the head, the headset may generate a control signal for controlling the external device by sensing the movement of the head for the remote control of the external device. However, the daily head movement of the user and the head movement for external device control can not be distinguished. Therefore, a safety biosignal is utilized to distinguish the daily head movement of the user from the head movement for external device control. The safety signal is a vital signal generated by the movement of the eyeball. The user generates a safety signal according to routine eye movements. Therefore, when the head movement and the safety signal are simultaneously used, a control signal for controlling the external apparatus can be generated.

The headset type remote controller according to an embodiment of the present invention can be applied to a smart TV. Smart TV can be used not only for broadcasting but also for applications that can utilize various contents. Accordingly, the headset-type remote controller according to the present invention can detect the biometric signal (safety degree, brain conduction, body temperature, pulse wave signal) of the viewer and transmit it to the smart TV. Accordingly, the smart TV can provide contents using the received bio-signals.

Smart TV can provide screen division function. Split-screen TVs can provide multiple channels simultaneously on a single TV. When the first viewer watches the first broadcast channel and the second viewer watches the second broadcast channel, one of the first viewer and the second viewer can not hear the desired broadcast channel. Therefore, a wireless headphone is required for one of the first viewer and the second viewer to hear the desired broadcast channel sound. However, when a wireless headphone is used, a viewer who wears a wireless headphone requires a separate headset type remote controller for changing a broadcasting channel. In this case, a headset-type remote controller according to an embodiment of the present invention can be used.

The smart TV may be a dual screen TV providing a specific screen to the wearer of the special glasses. In this case, a headset-type remote controller according to an embodiment of the present invention can be used.

When the reference setting mark is located at the center of the screen and then moves downward at a predetermined position vertically and then returns to the center of the screen, the minimum safety signal level is set as the second safety level reference signal. The time for returning the reference setting mark may be between 0.1 second and 1 second. The second sound safety reference signal can be obtained once at the beginning when the headset type remote controller 100 is used. If necessary, the value of the second sound safety reference signal can be secured through the initialization process. In order to obtain the second negative stability pulse signal, the second channel safety signal should be smaller than the second negative safety signal.

The second amount of stability reference signal is obtained when the external device 200 is a TV or a computer screen and the pupil tracks a reference setting mark presented on the screen while the head is fixed. When the reference setting mark is located at the center of the screen and moves up and down at a certain position and then back to the center of the screen, the maximum safety signal level is set to the second safety level reference signal. The time for returning the reference setting mark may be between 0.1 second and 1 second.
