I do not have any experience with these, but here are some other ones to
look at:

(I do have experience with this switch, but never tried using it with
muscle activation only)

Hi Jackie,
I had one client who used the EMG switch from Tinkertron with a Tobii I
Series device for a while after she could no longer use eye tracking.
Dinal was willing to accept a return if it didn't work for my client but
it worked better than anything else.

Hello everyone,

I am trying to get a good comparison of different EMG switches to find
the best choice for a client.  Problem is, I only have experience with
the wired older Neuroswitch by Control Bionics and nothing more. I don't
believe Control Bionics is compatible with Windows products yet-just Mac
OS and now iPad's.  Looking for ANY feedback of any EMG switches
available on the market today.  I understand the switch might not be
appropriate for the client currently, but want to ensure I'm researching
this specific activation method as fully as possible (and for future
cases and knowledge).

Details:
Current Setup: Tobii I-12 using eyegaze, current activation method
gumball switch or dwell.
EMG potential location: Forearm (unknown yet whether anterior or
posterior), but plan to possibly move to locations above neck (?)

Here is what I found available that might work with the Windows OS
running on a Tobii I-series:
http://tinkertron.com/  (This one looks really similar as well:
https://www.gokeytech.com/products/emg-switch)
http://www.canassist.ca/EN/main/programs/technologies-and-devices/communication/headband-operated-emg-switch.html
(just head)
Questions:
1) Am I missing any EMG Manufacturer(s) from my online searches?
2) Has anyone used any EMG switch with the Tobii I-series device?
Feedback?

I appreciate any help in this, thank you!!  Please feel free to private
email me as well!!
