The HeadZmouse has been developed using gyroscopic technology to increase the computer accessibility for persons with physical disabilities. Demonstration will be included.

For persons with physical disabilities who have difficulty accessing computer using hands, the most important tool for accessing computer is the interface which assist input. Thus, it is important to consider alternative input methods of accessing computer other than standard input methods.

For people who are unable to access computer using standard mouse, they also have difficulty controlling mouse such as left and right click, double click, drag and drop, and wheel function. They may also have difficulty accessing standard keyboard when pressing one key or two keys at the same time. Therefore, HeadZmouse has been developed for those who have difficulty using standard mouse and keyboard.

In Korea, most of the head-controlled mouses have been imported from abroad and there was a need for the development of a domestic versions of head-controlled mouse. Since the devices have been imported from abroad, it is very difficult to get repair and maintenance services.

The disadvantages of existing head-controlled mouses are: heaviness, the head set puts pressures on the head, it is difficult to move head around, and the design is not very ergonomic, and so on. Considering these factors, the head set of the HeadZmouse has been designed very ergonomically to alleviate these problems so that it sits on the head comfortably with less fatique. The user can control the cursor on the screen precisely and freely using only head movement.

Applying the gyroscopic technology, HeadZmouse has been developed to simulate left and right mouse click, double click, drag and drop, and even a wheel function for navigating web. This device was designed to work on both PC and Macintosh environments using a USB cable. The first time you use this device, you'll find out how much freedom it offers to someone who can`t use his or her hands freely. Rather than being tied to your computer, simple manipulation such as blowing an air (breathing) into a sonic sensor can simulate all the functions which standard mouse has, even including a wheel function. By accessing computer this way, the user can operate computers for education, rehabilitation, employment, and playing games.

The functions of each part of the device are explained as follow:
1. Mouse click on left button by blowing air into the sonic sensor #1
2. Mouse double click by blowing air twice into the sonic sensor #1
3. Mouse drag and drop by blowing air long (long breathing) into the    sonic sensor #1
4. Mouse Click on right button and click wheel button by blowing air for 1 second into the sonic sensor #2.
5. Reset button.
6. Cursor movement sensitivity control switch.

Compare to other head-controlled mouses, some of the advantages of using HeadZmouse are as follow:
1. Enhanced ergonomic design makes the head set sit on the head more comfortably and can control head movements more easily.
2. You can freely control cursor movements without any receiving and transmitting parts involved.
3. By blowing air into a sonic sensor, you can click, double click   drag and drop, and do the wheel function of the standard mouse.
4. It is inexpensive compared to other head-controlled mouses.
5. It is compatible with both Window and Macintosh environments as long as there is a USB port and a USB cable.
6. No extra software setup is necessary. You can use it right after connecting the USB cable directly into a USB port.
7. You can easily navigate web pages and read textbooks with wheel function.
8. You can adjust the sensitivity of the cursor movements by yourself with a cursor movement sensitivity control switch
