2. 1. Glasses Review Problems Encountered Consequences 2. Points To Ponder

3.  Glasses too heavy ◦ Problem: Patient is uncomfortable ◦ Consequences:  Results are irrelevant (patient not on usual behavior)  Glasses too low (signal undetected on low sensors) ◦ Solution: Helmet

4.  Glasses still bit too low ◦ Problem: Magnet passes sensor height ◦ Consequence: “Horns”

6.  Glasses too low ◦ Problem: Magnet passes sensor height ◦ Consequence: “Horns” ◦ Solution: Nosepiece adjustment

7.  Glasses too far ◦ Problem: Signal too weak! ◦ Consequence: Can’t detect blinks

9.  Glasses too far ◦ Problem: Signal too weak! ◦ Consequence: can’t detect blinks ◦ Solution 1: Temple strengthening  Highly unpleasant ◦ Solution 2: Ski strap  Great improvement  Still uncomfortable in long sessions  Hard to calibrate

12.  New platform, comfortable to the patient is required!

13.  Eye movement vs. Blinks ◦ What’s the difference?

14.  Partial blinks ◦ First results are positive, but were “an accident” ◦ Need a volunteer with special abilities!

15.  For now, we’re stuck with horns…  With better glasses – the potential is huge!  We’re at home stretch… ◦ Better glasses ◦ Bigger database
