In this paper we present a novel method to evaluate guidance systems and navigation solutions for public infrastructures based on an immersive virtual environment in combination with a mobile eye tracking system. It opens new opportunities for wayfinding studies in public infrastructures already during the planning phase. Our approach embeds an interface for natural locomotion in the virtual en...

This research describes an approach to objective assessment of mental workload, by analyzing differences in pupil diameter and several aspects of eye movement (fixation time, saccade distance, and saccade speed) under different levels of mental workload. In an experiment, these aspects were measured by an eye-tracking device to examine whether these are indeed indicators for mental workload. Pu...

Future technologies will enable carriers to collect additional flight data for Flight Operational Quality Assurance. This paper describes how analysis of these data using model-based activity tracking can automatically assess the causes of detected deviations to support safety-enhancement efforts. The paper describes the activity tracking methodology implemented in the Crew Activity Tracking Sy...

Monocular gaze estimation is usually performed by locating the pupils, and the inner and outer eye corners in the image of the driver’s head. Of these feature points, the eye corners are just as important, and perhaps harder to detect, than the pupils. The eye corners are usually found using local feature detectors and trackers. In this paper, we describe a monocular driver gaze tracking system...

The objective of the tutorial is to give an overview on how eye tracking is currently used and how it can be used as a method in human computer interaction research and especially in usability research. An eye tracking system records how the eyes move while a subject is completing a task for example on a web site. By analyzing these eye movements we are able to gain an objective insight into th...

Research has shown that when viewing still images, people will look at these images in a different manner if instructed to evaluate their quality. They will tend to focus less on the main features of the image and, instead, scan the entire image area looking for clues for its level of quality. It is questionable, however, whether this finding can be extended to engulf videos considering their d...

The locations of the eye pupil centers are used in a wide range of computer vision applications. Although there are successful commercial eye gaze tracking systems, their practical employment is limited due to required specialized hardware and extra restrictions on the users. On the other hand, the precision and robustness of the off the shelf camera based systems are not at desirable levels. W...

Tracked objects rarely move alone. They are often temporarily accompanied by other objects undergoing similar motion. We propose a novel tracking algorithm called Sputnik Tracker. It is capable of identifying which image regions move coherently with the tracked object. This information is used to stabilize tracking in the presence of occlusions or fluctuations in the appearance of the tracked o...

Intonation plays an integral role in comprehending spoken language. It encodes post-lexical pragmatic functions such as sentence modality and discourse contexts. The present experiment investigates how and when listeners integrate intonational information to anticipate reference resolution. While most work on the real-time processes of intonation-based intention recognition has utilized eye tra...

In this work we investigate building indoor location based applications for a mobile augmented reality system. We believe that augmented reality is a natural interface to visualize spacial information such as position or direction of locations and objects for location based applications that process and present information based on the user’s position in the real world. To enable such applicati...
