HeadMaster Plus is a head pointing system which provides full mouse control of computers to persons who cannot use their hands but who have good head control. Moving one's head moves the cursor on the screen. Activating the puff switch or other external switch makes selections. On-screen keyboards such as WiViK allow for word processing and other text entry.

HeadMaster Plus can emulate the most popular mouse input systems:

	Apple Desktop Bus for MacintoshTM and Apple IIGSTM
	MicrosoftTM mouse for IBMTM and compatibles with an RS232 serial port
	PS/2TM for IBMTM and compatibles equipped with the PS/2TM mouse port
	Sun MicrosystemsTM/Unix

You can change the HeadMaster Plus from Apple to IBM compatibility just by flipping a switch. There is no additional hardware required. Full support for one-, two-, and three-button mice is built in. You can operate the mouse button with the puff switch mounted on the headset or plug other switches into the back of the control box.
