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

SAW - Special Access to Windows - is a programmable on-screen keyboard. It is a powerful tool for providing Access to the Windows operating system for people who need alternative Switch or Pointing device input options.
The new SAW 6 version - supported by the AEGIS project (http://www.aegis-project.eu/) - is now available. It is fully Windows 7-10 compatible, supports Unicode, includes its own "Blade" word prediction and abbreviation expansion engine, can interact with the CCF-SymbolServer for graphic symbol support (http://www.conceptcoding.org/), and adds several other features to make creating interfaces easy for those who use alternative inputs.
