Mobile eyetracking is a recent method enabling research on attention during real-life behavior. With the EyeSeeCam, we have recently presented a mobile eye-tracking device, whose camera-motion device (gazecam) records movies orientated in user's direction of gaze. Here we show that the EyeSeeCam can extract a reliable vergence signal, to measure the fixation distance. We extend the system to determine not only the direction of gaze for short distances more precisely, but also the fixation point in 3 dimensions (3D). Such information is vital, if gaze-tracking shall be combined with tasks requiring 3D information in the peri-personal space, such as grasping. Hence our method substantially extends the application range for mobile gaze-tracking devices and makes a decisive step towards their routine application in standardized clinical settings.
