Blink detection actuator switch

[unixunion]

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.

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.

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. /K

Hi Kegan, I've also downloaded Click2Speak as an alternative to ACAT. Check out the following, eye tracking may be an option for you. * http://www.click2speak.net/category/our-journey * https://tobiigaming.com/products/ 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!

@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.

• q to quit
• r to restart
• s to display the current aspect ratio of the left eye
• d to display the current aspect ratio of the right eye

the threshold ratio is currently set to 4.

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

[zelmon64]

@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.
