Description

External input method and device using keypad of user equipment {METHOD AND APPARATUS FOR EXTERNAL INPUT BY USING USER DEVICE}

The present invention relates to a user device having an input means, and more particularly, to an external input method and apparatus using a keypad of a user device suitable for using a user device having a character and numeric input means as an input device of another system.

The present invention is derived from a study conducted as part of the IT new growth engine core technology development project of the Ministry of Information and Communication [Task Management Number: 2005-S-065-03, Task Name: Wearable Personal Station Development].

In recent years, when a user has a large number of intelligent information devices, it has become possible to significantly reduce the size of the device itself due to the development of hardware technology, but the input / output devices that directly interface with the user's body are too large. If it is small, it is rather inconvenient to use, which has been an obstacle to miniaturization of the device. In the ubiquitous computing era, there is still a need for character input for information devices everywhere, but configuring hardware devices for character input usually affects the physical size of the device and is used in kiosk devices in public places. In this case, if the I / O device is composed of one system, only one user can use it at a time, which reduces the availability.

If personal handheld devices such as mobile phones, which are carried by most people today, can be commonly used as text input tools for various information devices, the physical size of the device can be reduced by not having to configure a physical device for text input. Although it is not very fast, the user can already input text using a familiar input method anytime, anywhere without any additional learning.

For this purpose, there are several prior arts for utilizing a personal digital assistant as an input device of another system. Related prior art "How to use the touch screen of a mobile phone as an external input device of the computer (application number: 2004-0022002)" proposes a method to use by transmitting the coordinate value of the touch screen of the mobile terminal to the computer. Although many personal portable terminals provide a text input method using a touch screen and an on-screen keyboard, the preceding patent merely suggests an application of a coordinate level to transmit the touch screen coordinates of the terminal to a computer. It does not explain any specific details for this.

In another prior patent "Mobile Phone with Wireless Keyboard Function (Application No .: 2002-0041051)", the mobile phone has a built-in short-range wireless communication function such as Bluetooth, and utilizes the numeric and Korean-English keyboard functions of the mobile phone. Although a method of using the device as an input means of the present invention is presented, it does not present a specific embodiment or description for use as an input means of another device.

Another prior patent "Wireless terminal system and method for sharing an input device with another network-connected wireless terminal (application number: 2004-0083099)" can be used as a mutual input device between the two terminals, the current mobile phone terminal is each producer Different character input systems are used by each user, so that the input side can identify them, and if the receiving side uses a different input system, it informs the user with an appropriate interface so that they can input characters according to the method. It shows how to construct a string of strings, store it, and pass it on.

However, if the two devices are terminals produced by different producers, and the system for character input is different from each other, even if the input method of the counterpart device to be input is identified and inputted, the additional information is different from the actual physical device configuration. This may cause inconvenience to the user in that it should be used with reference.

In a system using a keypad of a user device according to the prior art operating as described above as an external input module of another device, the device may be connected to an external input module of another device through a keypad or a touch screen of the user device through a wired or wireless connection between the devices. Although the basic concept of using is suggested, in order to receive a character input method of a user device using a different technology from another device, there is a problem in that the user can use the same character method or only a user device registered in advance.

Accordingly, the present invention provides an external input method and apparatus using a keypad of a user device that can use a user device having a character and number input means as an input device of another system.
