Klingner The Pupillometric Precision Of A Remote Video Eye TrackerKalle
To determine the accuracy and precision of pupil measurements made with the Tobii 1750 remote video eye tracker, we performed a formal metrological study with respect to a calibrated reference instrument, a medical pupillometer. We found that the eye tracker measures mean binocular pupil diameter with precision 0.10 mm and mean binocular pupil
dilations with precision 0.15 mm.

Komogortsev Biometric Identification Via An Oculomotor Plant Mathematical ModelKalle
There has been increased interest in reliable, non-intrusive methods of biometric identification due to the growing emphasis on security and increasing prevalence of identity theft. This paper presents a new biometric approach that involves an estimation of the unique oculomotor plant (OP) or eye globe muscle parameters from an eye movement trace. These parameters model individual properties of the human eye, including neuronal control signal, series elasticity, length tension, force velocity, and active tension. These properties can be estimated for each extraocular muscle, and have been shown to differ between individuals. We describe the algorithms used in our approach and the results of an experiment with 41 human subjects tracking a jumping dot on a screen. Our results show improvement over existing eye movement biometric identification methods. The technique of using Oculomotor Plant Mathematical Model (OPMM) parameters to model the individual eye provides a number of advantages for biometric identification: it includes both behavioral and physiological human attributes, is difficult to counterfeit, non-intrusive, and could easily be incorporated into existing biometric systems to provide an extra layer of security.
Palinko Estimating Cognitive Load Using Remote Eye Tracking In A Driving Simu...Kalle
We report on the results of a study in which pairs of subjects were involved in spoken dialogues and one of the subjects also operated a simulated vehicle. We estimated the driver’s cognitive load based on pupil size measurements from a remote eye tracker. We compared the cognitive load estimates based on the physiological pupillometric data and driving performance data. The physiological and performance measures show high correspondence suggesting that remote eye tracking might provide reliable driver cognitive load estimation, especially in simulators. We also introduced a new pupillometric cognitive load measure that shows promise in tracking cognitive load changes on time scales of several seconds.
Ashtiani Blink Write2 An Improved Text Entry Method Using Eye BlinksKalle
Areas of design improvements for BlinkWrite, an eye blink text entry system, are examined, implemented, and evaluated. The result, BlinkWrite2, is a text entry system for individuals with severe motor impairment. Since the ability to blink is often
preserved, even in severe conditions such as locked-in syndrome, BlinkWrite2 allows text entry and correction with blinks as the only input modality. Advantages of BlinkWrite2
over its predecessor include an increase in text entry speed. In a user evaluation, 12 participants achieved an average text entry
rate of 5.3 wpm, representing a 16% increase over BlinkWrite and a 657% increase over the next fastest video-based eye blink text entry system reported in the literature.
Kammerer How The Interface Design Influences Users Spontaneous Trustworthines...Kalle
This study examined to what extent users spontaneously evaluate the trustworthiness of Web search results presented by a search engine. For this purpose, a methodological paradigm was used in which the trustworthiness order of search results was experimentally manipulated by presenting search results on a search engine results page (SERP) either in a descending or ascending trustworthiness order. Moreover, a standard list format was compared to a grid format in order to examine the impact of the search results interface on Web users’ evaluation processes. In an experiment addressing a controversial medical topic, 80 participants were assigned to one of four conditions with trustworthiness order (descending vs. ascending) and search results interface (list vs. grid) varied as between-subjects factors. In order to investigate participants’ evaluation processes their eye movements and mouse clicks were captured during Web search. Results revealed that a list interface caused more homogenous and more linear viewing sequences on SERPs than a grid interface. Furthermore, when using a list interface most attention was given to the search results on top of the list. In contrast, with a grid interface nearly all search results on a SERP were attended to equivalently long. Consequently, in the ascending trustworthiness order participants using a list interface attended significantly longer to the least trustworthy search results and selected the most trustworthy search results significantly less often than participants using a grid interface. Thus, the presentation of Web search results by means of a grid interface seems to support users in their selection of trustworthy information sources.
