“…The first system of this kind was the commercial Tobii eye tracker [31]; it allows a head movement volume of 30 9 15 9 20 cm and a maximum head motion speed of 15 cm/s. Recently, several academic groups have built similar single-camera systems [11,13,20]. Guestrin and Eizenman's system [11] allows only small head movements, but it appears that their well-founded approach would allow larger head movements if the resolution of the camera was higher.…”

This paper presents a principled analysis of various combinations of image features to determine their suitability for remote eye tracking. It begins by reviewing the basic theory underlying the connection between eye image and gaze direction. Then a set of approaches is proposed based on different combinations of well-known features and their behaviour is evaluated, taking into account various additional criteria such as free head movement, and minimum hardware and calibration requirements. The paper proposes a final method based on multiple glints and the pupil centre; the method is evaluated experimentally. Future trends in eye tracking technology are also discussed.

“…In head pose estimation, many of the approaches proposed in the literature require more than one camera, or extra equipment [17][18][19][20][21], making the final system expensive, complex or intrusive. Furthermore, algorithmically, some methods require a set of facial features to be detected and tracked with a very high degree of accuracy [22,23].…”

This paper investigates the use of a gaze-based interface for testing simple shared attention behaviours during an interaction scenario with a virtual agent. The interface is non-intrusive, operating in real-time using a standard web-camera for input, monitoring users' head directions and processing them in real-time for resolution to screen coordinates. We use the interface to investigate user perception of the agent's behaviour during a shared attention scenario. Our aim is to elaborate important factors to be considered when constructing engagement models that must account not only for behaviour in isolation, but also for the context of the interaction, as is the case during shared attention situations.

Abstract. This paper briefly summarises our results on gaze guidance such as to complement the demonstrations that we plan to present at the workshop. Our goal is to integrate gaze into visual communication systems by measuring and guiding eye movements. Our strategy is to predict a set of about ten salient locations and then change the probability for one of these candidates to be attended: for one candidate the probability is increased, for the others it is decreased. To increase saliency, in our current implementation, we show a natural-scene movie and overlay red dots very briefly such that they are hardly perceived consciously. To decrease the probability, for example, we locally reduce the temporal frequency content of the movie. We here present preliminary results, which show that the three steps of our above strategy are feasible. The long-term goal is to find the optimal real-time video transformation that minimises the difference between the actual and the desired eye movements without being obtrusive. Applications are in the area of vision-based communication, augmented vision, and learning.
