Abstract

There are provided an optical pointing device and a personal portable device employing the same, the optical pointing device in which a horizontal optical path is formed, thereby minimizing the thickness of an optical system and providing a sufficient depth of a focus. The optical pointing device includes a cover glass directly contacting an object, a light source unit emitting light to the cover glass, and a light receiving unit reflecting the light reflected by the object in a predetermined direction via the cover glass and condensing the light in the predetermined direction, and picking up an image of the light. According to the present invention, pointing is possible by using the surface of a finger and a horizontal optical path is formed such that the thickness of an optical system is minimized, and a sufficient depth of a focus is provided, thereby keeping a beautiful exterior of an ultra slim personal portable device and performing convenient pointing.

Description

technical field [0001] The present invention relates to a user interface device, and more particularly, to an optical pointing device mountable on a compact personal portable device such as a mobile phone and a personal portable device using the optical pointing device. Background technique [0002] Typically, personal portable devices such as mobile phones and personal digital assistants (PDAs) employ a user interface using a keypad. Specifically, a conventional personal portable device includes a keypad formed of a plurality of buttons for inputting numbers or letters, so that a user can push a button of the keypad to input a phone number or a sentence. [0003] Recently, since wireless Internet services such as wireless broadband (WIBRO) services are widely used, Windows operating systems supporting a Graphical User Interface (GUI) are adopted in personal portable devices. Windows CE as an operating system (OS) is available for personal portable devices. In addition, wi...
