Evaluation of a radio tuning task on Android while driving

Year: 2015

Authors: M Krause, C Angerer,K Bengler

We implemented the AAM reference radio tuning procedure with some modifications for Android and tested it against a hardware radio on a tablet and on a smartphone. The used measurement methods involved an AAM track with driving metrics and eye tracking, a Lane Change Test (LCT) and occlusion testing. The metrics are reported and compared. The glance metrics seem to be potentially influenced by a carry-over effect from a training task toward longer glance durations. Nevertheless, the results are promising for further testing and validation experiments. Due to the easy setup, more uniform hardware (Android tablet) and a procedure without experimenter announcements, the open source application could be a valuable tool in experiments.

Evaluation of observers’ sensitivity to lens distortion discrepancies in stereoscopic moving pictures

Year: 2015

Authors: N Hottong, S Becker, S Beuck

One potential factor of distorted stereoscopic perception of a 3D movie may be slightly different lens aberrations between the two lenses of the stereoscopic camera. We considered typical lens distortions discrepancies of several stereoscopic camera types ranging from cine to small action cameras. The determination of a detection threshold of different groups of observers with respect to gender, stereoscopic ability, media affinity, etc. was a main research topic. In one of our subjective assessments we used a gaze tracking system by which the eye movement of the observers could be roughly determined. We found out that image texture and content-driven gaze sequence had a strong impact on observer's detection of stereoscopic aberrations. Minimal lens distortion discrepancy was already detected by at least 15.4% of the participants. The number of irritation statements increased with the magnitude of discrepancy. Observers showed highest sensitivity in still images or smooth camera travelling presenting many simple geometric objects. Still, up to 29% of the participants seemed to be quite immune against lens distortion discrepancies in spite of good stereo acuity as proven in Randot Stereo Vision test.

Excuse: Robust pupil detection in real-world scenarios

Year: 2015

Authors: W Fuhl,T Kübler,K Sippel,W Rosenstiel

The reliable estimation of the pupil position is one the most important prerequisites in gaze-based HMI applications. Despite the rich landscape of image-based methods for pupil extraction, tracking the pupil in real-world images is highly challenging due to variations in the environment (e.g. changing illumination conditions, reflection, etc.), in the eye physiology or due to variations related to further sources of noise (e.g., contact lenses or mascara). We present a novel algorithm for robust pupil detection in real-world scenarios, which is based on edge filtering and oriented histograms calculated via the Angular Integral Projection Function. The evaluation on over 38,000 new, hand-labeled eye images from real-world tasks and 600 images from related work showed an outstanding robustness of our algorithm in comparison to the state-of-the-art.

Exploiting the potential of eye movements analysis in the driving context

Year: 2015

Authors: C Braunagel, W Stolzmann,E Kasneci

Driving is a complex and highly visual task. With the development of high-end eyetracking devices, numerous studies over the last two decades have investigated eye movements of the driver to identify deficits in visual search patterns and to derive assistive, informative, and entertainment systems. However, little is known about the visual behavior during autonomous driving, where the driver can be involved in other tasks but still has to remain attentive in order to be able to resume control of the vehicle. This work aims at exploiting the potential of eye movement analysis in the autonomous driving context. In a pilot study, we investigated whether the type of the secondary task in which the driver is involved, can be recognized solely from the eye movement parameters of the driver. Furthermore, we will discuss several applications of eye movement analysis to future autonomous driving approaches, e.g., to automatically detect whether the driver is being attentive and – when required – to guide her visual attention towards the driving task.

Eye glance analysis of the surrogate tests for driver distraction

Year: 2015

Authors: L Hsieh,S Seaman, RA Young

The purpose of this study was to examine the eye glance patterns of Detection Response Tasks (DRTs) for assessment of driver distraction during simulated driving. Several types of DRTs across visual, tactile and haptic modalities were used to investigate driver distraction by the ISO Driving Distraction working group. As part of the working group, we conducted a simulated driving study examining driver performance while engaging the primary driving task with visual-manual or auditory-verbal secondary tasks. Results of eye glance analysis showed that the visual DRTs increased visual load in driving more than the tactile DRT. Subsequently, the visual DRTs marginally increased the total glance time for forward view by 6.27 seconds and significantly increased the detection response time by 135.79 ms than the tactile DRT. As for the secondary tasks, the visual-manual secondary task yielded significantly longer total eye-off-the-road time (effect size = 50.75 ms), as well as DRT response times than the auditory-verbal ones time (effect size = 55.85 ms). This study allowed us to examine the relationships between rated situational awareness, DRT performance, and glance patterns, yielding insights into the relationship between objective task performance measures and subjective ratings.

Eye movement synthesis with 1/

Year: 2015

Authors: A Duchowski,S Jörg, A Lawson, T Bolte

Eye movements are an essential part of non-verbal behavior. Non-player characters (NPCs), as they occur in many games, communicate with the player through dialogues and non-verbal behavior and can have a strong influence on the player experience or even on gameplay. In this paper we propose a procedural model to synthesize the subtleties of eye motions. More specifically, our model adds microsaccadic jitter and pupil unrest both modeled by 1/ f or pink noise to the standard main sequence. In a perceptual two-alternative forced-choice (2AFC) experiment we explore the perceived naturalness of different parameters of pink noise by comparing synthesized motions to rendered motion of recorded eye movements at extreme close shot and close shot distances. Our results show that, on average, data-driven motion is perceived as most natural, followed by parameterized pink noise, with motion lacking microsaccadic jitter being consistently selected as the least natural in appearance.

Eye Tracking Devices to Combat Distracted Driving

Year: 2015

Authors: R Garrett

Distracted driving has become an issue that occurs on a national scale. Particularly, in the state of California, which houses numerous motorists, distracted driving has a higher probability to occur. Regardless of location, distracted driving is becoming a growing and popular topic of discussion in public policy due to the dangers associated with it and the potential deadly effects it can have on the lives of many. For such reasons it is a noteworthy issue to be addressed. Many individuals may be familiar with the concept, to some degree, and the hazards that are involved, however, this epidemic continues to be ever-growing. As efforts have been made to deter the action of distracted driving through legal interventions, such efforts are not producing satisfactory results as statistical findings illustrate that the numbers of citations being issued to the public by law enforcement and traffic collisions are increasing year by year since the passing of the distracted driving laws. Additionally, the current laws only apply to a portion of some forms of distracted driving while other forms of it continue to be legal. This study will enlighten the reader of other forms of distracted driving, the frequency at which it occurs and the devastation it incurs. This study will also raise the question if California’s current method of combating this issue is deemed effective and propose an alternative to more effectively address the issue. While some motorists recognize and respect the dangers associated with distracted driving and do not engage in the activity, too many other individuals do not hold such regard for it and continue in their practices. Regardless, there must be a new approach in addressing this issue using eye tracking technology integrated for automobiles as a tool to ensure that all motorists, regardless of outlying factors, avoid the activity and incorporate responsible driving habits in order to better preserve the lives of all individuals.
