EyeLink Communication Boards (Lazer Cut or Printed)

in hardware

EyeLink is a partner supported communication method that allows an individual to communicate just through eye gaze. EyeLink is a simple and effective method of eye gaze communication which requires just an acetate or acrylic/Perspex sheet which is printed or engraved. EyeLink can be used with letters or symbols for communication. An EyeLink consists of a transparent frame with letters or symbols on, positioned between the person with communication difficulties and their conversation partner. Messages are generated by eye pointing to the relevant location on the frame and are recorded by the conversation partner.

Earswitch

in hardware

Ear switch as an assistive communication and control device / gaming switch and HCI In this hack I have used a USB otoscope camera to detect voluntary movement of a middle ear muscle (tensor tympani), to control assistive technology software (Grid3), the Microsoft On-Screen Keyboard , and as an "left-click" selection as an adjunct for eViacam head- tracking software. 75% of people recognise that they can contract their tensor tympani (a rumbling sound or muffling of the hearing eg when yawning/ tightly closing eyes etc). 17% could generate the contraction in isolation to other movements. I have shown with a USB auroscope from Amazon that this causes movement of the eardrum, and I have detected this movement with iSpy motion detection software and successfully used it to control (handsfree); asssistive software (Grid3), the On-Screen Keyboard and to function as a "left click" for head tracking. I hope this can help people to communicate
