Afraid I don't know about that, but as far as I can tell windows recognizes it as a normal webcam. So I'd expect it'd work for any program that utilizes a webcam.

You look around with the mouse and otherwise just follow the story. There are two situations where you can trigger something by blinking. One, something has an eye-symbol and can be activated by blinking and two, there is a metronome at the bottom of the screen indicating that blinking will conclude the scene. Well, thirdly, a lot of scenes might have neither for a bit, so you don't actually have to stare nonstop.

The first one doesn't really matter and could just as well be a mouse click. The second one seems to be more of the kicker, because you want to see how the scene plays out ("hold on to the memory") but it can be longer than you would normally keep your eyes open, so you do have to deal with a bit of a real life struggle to hold on to the memory (and maybe you blink, and the scene concludes).

I haven't tried using the mouse option yet, but if every scene just stays up till you click, you are missing out on this sense of physically struggling to stay in the scene, which feels like a bit of the point here.

Thanks for the detailed answer, appreciated.
So it basically does come down to one's capability of emulating your blinking behaviour and translating that into mouse clicks, as closely to the real thing as possible.
Well, I've never been someone not welcoming any additional challenge, no matter the way, shape or form.

That's a unique controller for sure.
If you have almost any laptop, you most likely have a webcam too. I think it might also be theoretically possible to use your mobile phone camera, but that might take some tweaking to do.

You can get started from this, if you want to get adventurous with it:

EDIT: I now see that it has been discussed already, somehow I missed those messages even though I scrolled through the thread.

that's actually very cool.

thanks for the detailed answer. :)
