Key input method and apparatus for portable apparatus
First Claim
1. A key input apparatus for a portable apparatus, comprising:
- a display unit configured to display a key selected by a user input;
a light sensor comprising;
a plurality of light emitting elements disposed at predetermined intervals on a border of a first side of the display unit, anda plurality of light receiving elements disposed on a border of a second side of the display unit to face the light emitting elements, wherein the light emitting elements are configured to generate first light signals at a predetermined angle from a direction in which the light emitting elements face the light receiving elements and wherein the light sensor is configured to output light signal information of at least one of the light emitting elements and the light receiving elements; and
an input detection unit configured to;
receive the light signal information from the light sensor,detect at least one of the light receiving elements that receive the first light signals using the light signal information, anddetect a user'"'"'s space input position using the at least one of the light receiving elements that receive the first light signals if the at least one of the light receiving elements that receive the first light signals are detected.

Abstract
A key input apparatus for a portable apparatus includes a display unit that displays a key selected by a user input. The apparatus includes a light sensor comprising a plurality of light emitting elements and a plurality of light receiving elements. The respective light emitting elements generate first light signals upward at a predetermined angle from a direction in which the light emitting elements face the light receiving elements. The apparatus also includes input detection unit that detects the light receiving elements that receive the first light signals, and detects a user'"'"'s space input position using the light receiving elements that receive the first light signals if the light receiving elements that receive the first light signals are detected.
