Heat pointer is great and I really hope Apple follows it up with building proper eye tracking hardware and software into Macs & iDevices. It's such a great opportunity to improve UX and reduce RSI for everyone by sharing the load among more input sources. I've tried the Tobii stuff but it's not great, no solution out there has quite nailed the calibration nor the UX yet, as it requires OS-level UX changes. Every input source has a point after which it causes fatigue or pain - hands, head, eyes, tongue, feet, etc. The more the load is spread out, the better! This MouthPad looks fantastic as another input method to share the load.
