Problems solved by technology

[0005] However, such digital devices are too small to have a pointing device, and therefore use screen touch methods to configure them as user interface (UI) systems, or at least operate cellular phones using a keypad through which letters can be entered
[0006] Therefore, a portable digital device having UI functions like a notebook personal computer (PC) with a built-in pointing device has not been developed due to its small size.

Embodiment Construction

[0066] The present invention realizes a virtual keyboard together with a two-dimensional pointing device, controls the position of the pointer in the relative coordinate system when performing the original pointing function of the pointing device, and inputs letters into the virtual keyboard in the absolute coordinate system when performing the text input function middle.

[0067] The virtual keyboard input system according to the present invention can be used as an input device of a conventional desktop computer. But its main use is for inputting letters, numbers, etc. into portable digital devices such as cellular phones, personal digital assistants (PDAs), or remote controls.

[0068] figure 1 is a block diagram of a virtual keyboard input system using a pointing device according to an embodiment of the present invention.

[0069] see figure 1 , the virtual keyboard input system includes a sensor unit 110 , a switch unit 120 and a control unit 130 .

[0070] The sensor ...

Abstract

Provided is a virtual keyboard input system using a pointing device in a digital de vice. The virtual keyboard input system includes: a sensor unit sensing a contact and a two-dimensional contact position; a switch unit; and a control unit dividing a contact sensitive region of the sensor unit into multiple division regions according to XY coordinates, assigning virtual keys of a virtual keyboardto the division regions, and when the switch unit is turned on, controlling an input of information for a virtual key assigned to a division region which is contacted among the division regions.

Description

technical field [0001] The present invention relates to a virtual keyboard input system using a pointing device in a digital device, and more particularly, to a system for setting a virtual keyboard as a two-dimensional pointing device (such as a touchpad or a touch screen) using an absolute coordinate system and passing A virtual keyboard input system for inputting letters using the two-dimensional pointing device. Background technique [0002] Computers are used with graphical user interface (GUI) systems via a mouse, which moves a pointer that points to commands and indicates locations on the computer monitor. [0003] Nowadays, as the size of computers has become smaller, touch pads and pointing sticks have been developed as built-in pointing devices to replace mice and improve user convenience. [0004] Current portable digital devices (eg, personal digital assistants (PDAs), portable multimedia players (PMPs), and even cellular telephones) are becoming more and more l...
