Blink detection actuator switch #44

Closed unixunion closed 1 week ago

unixunion commented 7 years ago

I have a family friend who could use ACAT if it can do blink detection as a "switch". Is there any possibility to add "blink" as a actuator switch.

alexandre-mbm commented 7 years ago

You can use any switch (hardware or software) by binding it like a simulated keypressing for F12 key.

Did you manage to find a 'blink' actuator and configure it as an F12 trigger? I have an MS friend who may also have to rely on blinking as most of her other faculties are lost.

unixunion commented 7 years ago

No I didn't find any sw that could do the blink detection. :/ I reached out to many people but seems like it's not something anyone wants to build.

Hi Kegan,

I've also downloaded Click2Speak as an alternative to ACAT. Check out the following, eye tracking may be an option for you.

Cheers, Ralf

Hi, I have tried Emotiv Epoc+ but I cannot make it works with ACAT... Is there anyone who could give me any advice how to connect this...? I am looking for solution for woman who has MS... We think that blinking should be the best... I will be glad for any hint how to do it... Thank you indeed!

zelmon64 commented 7 years ago

@ahaleksandra I've made a blink actuator using OpenFace. It sends F22 so that it shouldn't conflict with any thing so add that as another trigger to the keyboard actuator.

OpenFace_Blink_Actuator_v0.0.1_x86 OpenFace_Blink_Actuator_v0.0.1_x64

You'll probably need to install the Visual C++ redistributable package.

the threshold ratio is currently set to 4.

LaurentBerger commented 7 years ago

@zelmon64 thanks for code sharing. I have read your code and to send a F22 do you use only boost only ?

zelmon64 commented 7 years ago

@LaurentBerger it uses SendInput. I'm not sure what you mean about using boost. I only copied an example I found. If there's a better way I'll happily change it.

Edit: for reference here's where I found the example I used: http://forums.codeguru.com/showthread.php?377393-Windows-SDK-User-Interface-How-can-I-emulate-keyboard-events-in-an-application

I added the pause before releasing the key because without it ACAT wouldn't get triggered.
