For applications that share an eye gaze to work together, they need to cooperate.
Two common issues that occur are:
- Some eye gaze cameras can only have one process reading the eye gaze data at a time (e.g. EyeTech DS TM5 Mini, Irisbond Duo & Hiru, Alea Intelligaze, etc.). When one app takes over, the previous app needs to release the camera
- Mouse emulation toolbar can overlay an app that doesn't need mouse emulation, because it processes eye gaze directly rather than through mouse clicks
Here is a sample proposal of how eye gaze apps can be aware of each other so they can coordinate handoff:
