Description

Remote computer terminal control device {Remote Control Device of Computer}

The present invention relates to a small size and light weight housing of a remote computer terminal control device having an additional function of receiving a function key value of a computer terminal wirelessly from a remote location and having an additional function that can be used for presentation.

In recent years, with the development of information processing and data communication technology, computer terminals such as personal computers (PCs) and work stations (Work stations) have gone beyond the concept of exclusive possessions of some specialists, and thus, general life and work of the general public. It is an essential element to perform its functions.

In particular, the personal computer is high performance and low price in line with the popularization of information, and is used in various fields such as communication means and information storage means of the general public.In the enterprise, most of the presentation, general office work, graphic work, etc. Personal computers are used for work.

In general, a computer terminal uses a keyboard composed of character keys, numeric keys, special keys, and function keys to receive unique characters such as letters, numbers, special characters, and control means as input devices. The cable is connected via the keyboard input port of the computer terminal.

Therefore, in order for a user to perform a presentation in an enterprise, the user should execute a presentation file written in MS Office, Hunminjeongeum, etc., display it on a board through a displayer, and perform screen switching through a keyboard.

However, in general, since the keyboard is connected to the main body of the computer terminal through a cable as mentioned above, when the board and the main body of the computer terminal are remotely located, a third party performs control such as screen switching according to a user's signal. Each time the screen is switched, the user must move to the keyboard of the computer terminal.

In this case, there is a disadvantage in that the presentation progress can be inhibited and the concentration of the user can not be maximized, resulting in a maximized presentation effect. A screen switch in which a cable having a predetermined length of is connected to an input terminal of a computer terminal is used.

However, such a screen switcher also needs to be connected to the input port of the personal computer through a cable, which may interfere with the presentation. If the user needs to perform the presentation at a distance from the board, the cable distance is limited. There is a problem that can not be used.

In addition, during the presentation, the user typically uses an indicator or indicator rod using a light beam such as a laser to indicate a portion corresponding to the currently described portion of the displayed content.

Therefore, in order for a user to perform a presentation in a company or the like, the user needs to switch the screen to a wired screen switcher while instructing the content displayed on the board through an indicator, and thus cannot completely solve the factors that hinder the performance of the presentation.

Recently, a wireless keyboard for computer terminals has been developed. However, such a wireless keyboard has limitations in its size and weight for portable use, and its number of keys is so complicated that it is not suitable for presentation. There is a problem.

Therefore, there is a demand for development of a remote computer terminal control apparatus having additional functions that can be used for presentations and the like while switching or controlling a screen displayed on a computer terminal at a remote location without using a cable.

The present invention has been made in the background, by providing a function key value of a computer terminal from a remote location wirelessly, by providing a small, lightweight remote computer terminal control device having an additional function that can be used for presentation, The purpose of the present invention is to provide a presentation additional function such as a laser pointer, and to control the screen switching and the like displayed on the computer terminal at a remote location.
