Jo is from my home town and she is doing really amazing things with Snap Core and infrared toys to elicit communication. Check it out.
Jo purchased a few infrared toys from her local drug store. Jo says: "Buy 2, get one free at Walgreens! Get you some fun creatures for your eye gaze kids! They have spiders too".
With the exception of the SC Tablet, every Tobii Dynavox device from the Indi-7 to the i16 eye gaze computer has infrared built into it. I'm sure you all will agree, this is high level ninjtsu!
