HeadMaster Frequently Asked Questions
What is HeadMaster? HeadMaster controls the mouse by head movements. It allows someone who cannot use their hands or arms to operate a personal computer. The mouse button is operated by a puff switch mounted on the headset or by other switches plugged into the back of the control unit. Back to Top There is no movement of the cursor even though the HeadMaster is on. What should I do to make the cursor operated by the HeadMaster? When you first connect the HeadMaster to a computer you must indicate which mouse you are using. On the side of the control unit there are three small gray switches. On the bottom of the control unit there is a label that identifies these switches. Tell the control unit which mouse you are using by setting according to the positions for your mouse on the label. Set the three buttons on the left of the HeadMaster Control Unit like this: down, up, up (left to right from the front.) To get back to the normal position, change these buttons to any other position. Back to Top How do I place the HeadSet? Place the headset over the head above the years. Sensors should be pointing forward as shown below:  Back to Top How do I plug in the Puff switch and Mouth tube? The black end of the puff switch has a phone jack attached to it. Plug this into the connector on the bottom of one of the headpiece sensors. The puff switch is delicate, so gently insert the tube by slowly twisting it back and forth into the switch. Remove it the same way. Back to Top Should I discard the mouth tube after use? For Hygenic reasons, you should replace used mouth tubes frequently. Discard the used tubes. Dont try to wash them out. Please contact the Lab Aide to get a new tube. Back to Top How do I select the sensitivity of the cursor? The HeadMaster Plus turns head motion into cursor motion on the computer screen. You can deciede how much cursor motion results from a given amount of head motion by selecting a SENSITIVITY setting of LO, MED or HI from the back of the control unit. "Sensitivity" refers to how fast or how slowly the cursor moves when you move your head. It is recommended to start with the sensitivity set to LO. Back to Top How do I "Click" on a screen icon? Point with your head to move the cursor until it resets on top of the icon or window till you wish to click. Slightly increase the air pressure inside your mouth and then immediately release the pressure -- the idea is to create a short "pressure pulse." There is no need to let air escape around the edges of the mouth tube as you release the pressure. Try to maintain the seal with your lips. When you do this correctly, the icon will switch from a light color to a dark color to indicate that you have selected it. Back to Top How do I "double-click" a screen icon? Double-clicking is an easy way to open disk drives or different programs. To double click with the puff switch, make two air pulses quickly, one right after the other. Remember, an air pulse is when you slightly increase and then release the air pressure inside your mouth. Try to keep your head perfectly still when double-clicking. Back to Top How do I "drag" a screen icon? Point the icon or window you want. Increase the air pressure in your mouth until the icon switches from light to dark. Without relaesing the air pressure, move your head. The icon or window should follow your head movement. Stop moving your head and release the air pressure in your mouth to let go of the screen object. Back to Top |
