Detect Eye blinks and Long looks up or down - Using CV/ML
Some clients we see have very small movements and usually in one body part. For example, we have had a number of clients who have had a brainstem stroke and have very limited physical/motor skills except at the eye (and sometimes eye brow). With these clients we are lucky if they can use eyegaze - but often - this technology is not suitable. So we need to look at "Switches". Switches are simply put, a switch, which turns something on or off - and we use a standard 3.5mm mono audio jack for these switches - so all sorts of equipment can be operated. On a computer based communication device the software can "Scan" to different elements on the screen. This is how Stephen Hawking used his communication system - by raising his cheek and with an on-screen scanner select the item/letter he was spelling out. Although slow - it can be very efficient.
So with these individuals we need a way of reliably detecting a look up - or a blink. Thes
