I looked through the api, stackoverflow and google, and didn't find anything. Is there a way in the API to access the camera that faces the eye? I would like to be able to tell if the user's eye is open or closed...is this possible with this version of the GDK?
Is that what the built in wink-to-take-a-picture app is doing?
AFAIK, you cannot currently determine open/closed, however there are some eye gestures that are supported, assuming that you have the latest version of Glass hardware.
From here, you can see the supported gestures:
BLINK("BLINK", 3),
DOFF("DOFF", 6),
DON("DON", 5),
DOUBLE_BLINK("DOUBLE_BLINK", 4),
DOUBLE_WINK("DOUBLE_WINK", 2),
NO_GESTURE("NO_GESTURE", 0),
WINK("WINK", 1);
Also, on that page, they explain how you have to listen to the com.google.glass.action.EYE_GESTURE
intent to receive the events:
If you are writing an app, the intent to listen for is
com.google.glass.action.EYE_GESTURE
. There is a public API to
enable/disable them in the undocumented package
android.glass.GlassGestureManager
. Get it via
Context.getSystemService("glass_gesture")
.
Check out winky's MainActivity.java for an example.
Here's another eye gesture example which interacts with eye gestures.
