HMD information apparatus and method of operation thereof
First Claim
1. An assembly of an information terminal including an HMD (head mounted display) and a key input apparatus, the assembly comprising:
- a micro display for displaying a virtual screen;
a key information storage unit for storing key map information of the virtual screen displayed by the micro display;
a detection signal generation unit for generating detection signals for identifying a user motion within a sensing distance set by a user;
a detection signal sensing unit having a reflection signal sensing unit for sensing detection signals reflected by the user'"'"'s body;
a recognition unit for recognizing the user motion based on reflected detection signals and key information based on the user motion; and
a control unit for displaying the key map information, sensing the user motion based on detection signals, and recognizing the sensed motion as specific key input.

Abstract
An apparatus and method for inputting a key input in an information terminal integrated with an HMD. The user is provided with a virtual screen, including a key map and a preview window, as a display screen via a display unit having a micro display. A detection signal generation unit generates signals, which are sensed by a detection signal sensing unit and recognized by a recognition unit, so that a telecommunication terminal can recognize the user'"'"'s motion without any separate HMD input device. Therefore, the user can input a desired key to an information terminal simply by moving their hands without any separate input device. This further improves the portability of the information terminal.
