In future, near-eye display devices will be commonly used by people with or without prescription glasses, with different eye topologies, and under different lighting variations. Gaze tracking is an important task for these near-eye devices. New robust gaze tracking methods should be explored for these sophisticated devices. The proposed method overcomes the problem of adaptability to eye topolo...

The detection of indoor landmarks remains a troublesome endeavour. The rise of more performant and user-friendly mobile eye tracking devices might offer a solution. A small-scale study was conducted in which a test population was given a navigational task and whereby eye movement measures and think aloud protocols were compared. The first results indicate that eye tracking has high potential fo...

Tracking the user’s eye-gaze information has been technologically possible for several decades. However, systems that track eye-gaze are still very expensive. The exorbitant price tag on commercial systems has resulted in limited use of eye-tracking technology. In this paper we examine the factors which contribute to the high costs of eye-tracking systems. We then propose several techniques and...

We present an independent, flexible, and easily programmable software program for generating a wide set of visual stimuli paradigms in eye-movement studies. The software, called ASTIDET (Advanced Stimuli Design for Eye Tracking), has been interfaced in real time with a high speed video-based eye tracking system in order to obtain a reliable measurement of saccades. Two saccadic paradigms have b...

In this paper, we use the optical-type eye tracking system to control powered wheelchair. The userís eye movements are translated to screen position using the optical-type eye tracking system. The pupil-tracking goggles with a video CCD camera and a frame grabber analyzes a series of human pupil images when the user is gazing at the screen. A new calibration algorithm is then used to determine ...

We describe an eye-tracking experiment that tested the effect of syntactic predictability on skipping rates during reading. We found that plural noun phrases were skipped more often than singular noun phrases, in syntactic contexts which induced a high expectation for a plural. We interpret this effect as evidence that the plural noun phrase has been predicted ahead of time. The results indicat...
