De kunst van sociale media. Ondanks dat zo langzamerhand iedereen wel een Hyves of LinkedIn-account heeft, hebben veel professionals geen idee welke mogelijkheden een social media als Hyves eigenlijk biedt. Als er een ding duidelijk is geworden door deze presentatie van Wouter te Winkel en Roos Simons van Hyves tijdens mondayatvakzuid, dan is het wel dat de mogelijkheden zo ongeveer eindeloos zijn, dat het aantal mogelijkheden groeit en dat het einde van deze groei nog niet in zicht is.
Wastlund What You See Is Where You Go Testing A Gaze Driven Power Wheelchair ...Kalle
Individuals with severe multiple disabilities have little or no opportunity to express their own wishes, make choices and move independently. Because of this, the objective of this work has been to develop a prototype for a gaze-driven device to manoeuvre powered wheelchairs or other moving platforms. The prototype has the same capabilities as a normal powered wheelchair, with two exceptions. Firstly, the prototype is controlled by eye movements instead of by a normal joystick. Secondly, the prototype is equipped with a sensor that stops all motion when the machine approaches an obstacle. The prototype has been evaluated in a preliminary clinical test with two users. Both users clearly communicated that they appreciated and had mastered the ability to control a powered wheelchair with their eye movements.

We propose a new way of analyzing pupil measurements made in conjunction with eye tracking: fixation-aligned pupillary response averaging, in which short windows of continuous pupil measurements are selected based on patterns in eye tracking data, temporally aligned, and averaged together. Such short pupil data epochs can be selected based on fixations on a particular spot or a scan path. The windows of pupil data thus selected are aligned by temporal translation and linear warping to place corresponding parts of the gaze patterns at corresponding times and then averaged together. This approach enables the measurement of quick changes in cognitive load during visual tasks, in which task components occur at unpredictable times but are identiable via gaze data. We illustrate the method through example analyses of visual search and map reading. We conclude with a discussion of the scope and limitations of this new method.
Daugherty Measuring Vergence Over Stereoscopic Video With A Remote Eye TrackerKalle
A remote eye tracker is used to explore its utility for ocular vergence measurement. Subsequently, vergence measurements are compared in response to anaglyphic stereographic stimuli as well as in response to monoscopic stimulus presentation on a standard display. Results indicate a highly significant effect of anaglyphic stereoscopic display on ocular vergence when viewing a stereoscopic calibration video. Significant convergence measurements were obtained for stimuli fused in the anterior image plane.
Eye tracking scanpaths contain information about how people see, but traditional tangled, overlapping scanpath representations provide little insight about scanning strategies. The present work describes and extends several compact visual scanpath representations
that can provide additional insight about individual and aggregate/multiple scanning strategies. Three categories of representations are introduced: (1) Scaled traces are small images of scanpaths as connected saccades, allowing the comparison of relative fixation densities and distributions of saccades. (2) Time expansions, substituting ordinal position for either the scanpath’s x or y-coordinates, can uncover otherwise subtle horizontal or vertical reversals in visual scanning. (3) Radial plots represent scanpaths as a set of radial arms about an origin, with each arm representing saccade counts or lengths within a binned set of absolute or relative angles. Radial plots can convey useful shape characteristics of scanpaths, and can provide a basis for new metrics. Nine different prototype scanning strategies were represented by these plots, then heuristics were developed to classify the major strategies. The heuristics were subsequently applied to real scanpath data, to identify strategy trends. Future work will further automate the identification of scanning strategies to provide researchers with a tool to uncover and diagnosescanning-related challenges.
Nagamatsu Gaze Estimation Method Based On An Aspherical Model Of The Cornea S...Kalle
A novel gaze estimation method based on a novel aspherical model of the cornea is proposed in this paper. The model is a surface of revolution about the optical axis of the eye. The calculation method is explained on the basis of the model. A prototype system for estimating the point of gaze (POG) has been developed using this method. The proposed method has been found to be more accurate than the gaze estimation method based on a spherical model of the
cornea.

Als communicatieprofessional kun je er eigenlijk niet meer omheen: de koppeling tussen on- en offlinecommunicatie. Maar waar begin je nu eigenlijk?
Aan de hand van inspirerende praktijkvoorbeelden nemen wij je mee in de wereld van pr anno 2011. In een vogelvlucht gaan we door de basis heen. Vervolgens verkennen wij de huidige mogelijkheden op het gebied van (online)communicatie. En hoe zet je deze in? Hoe creëer je een synergie tussen de verschillende middelen? Graag laten Nieke Kempen en Erik Janson je kennismaken met de nieuwste ontwikkelingen op het gebied van on- en offlinecommunicatie. Zij willen je vooral zelf laten ervaren hoe jij - vanuit jouw expertise - gebruik kunt maken van de beschikbare middelenmix.
