Apparatus and method for inputting keys using biological signals in head mounted display information terminal
First Claim
1. An apparatus for inputting keys using biological signals in an HMD (Head Mounted Display) mobile information terminal having an HMD, the apparatus comprising:
- a micro-display for displaying a virtual screen;
a memory unit having a key information storage unit for storing key-map information of the virtual screen displayed by the micro-display;
a biological signal sensing unit for sensing biological signals that include voltages produced from a face of a user;
a recognition unit for recognizing the sensed biological signals and key information according to the recognized biological signals; and
a control unit for recognizing the key information according to the biological signals as an input of a specified key.

Abstract
Disclosed is an apparatus and method for inputting keys using biological signals in an HMD (Head Mounted Display) mobile information terminal. The apparatus provides a virtual screen that includes a key map and a preview window to a user through a display unit having a micro-display, recognizes and inputs a key selected according to the user'"'"'s biological signals sensed through a biological signal sensing unit having an EOG (Electrooculogram) input unit and an EMG (Electromyogram) input unit for sensing and receiving the biological signals as key inputs. The apparatus recognizes through a recognition unit the key selected according to the user'"'"'s biological signals sensed through a biological signal sensing unit. The user can freely use the HMD mobile communication terminal without using his/her hands because the user can input his/her desired key to the HMD information terminal only by the movement of the user'"'"'s eyes and the biting of his/her right and left back teeth.
