ET-seminar 2012-02-10: Damon Tutunjian about his plans to record reading data on implicit agent activation in adjectival vs. verbal passives.
At todays ET-seminar, Damon Tutunjian presented an upcoming experiment for using eye-tracking to study implicit agent activation in adjectival vs. verbal passives. Understanding the purpose of this study requires an example, and Damon gave us the following:
(1) a. The new technology was very efficient to get ahead of the competitors.
b. The new technology… »
ET-seminar 2012-02-03: Kerstin Gidlöf about how stages in decision making can be seen in eye movement data
At today’s ET-seminar, we discussed how to detect cognitive states such as ’search’, ‘evaluation’ and ‘decision’ in eye-movement data. Although Kerstin examines decisions in supermarkets, the underlying question about cognitive processes is the same for all search tasks: radiology, psycholinguistics, visual search etc: it is clear that even if we see changes in eye movement… »
ET-seminar 2012-01-27: Ignace Hooge about search of small objects near borders
Today Ignace Hooge talked about visual search for specific, known targets - such as searching for a contact lens on the floor, a particular village in a map, or a tumor in a mammography image. It is known that the border of the object may masked by neighbouring borders, degrading the perceived contrast around the… »
ET seminar 2012-01-20: Kick-off, planning and form
At today’s seminar, we planned the spring semester. The interest in seminar slots promises that this can be another productive year in the eye-tracking group. There are still a few slots left, however. Contact us if you run eye-tracking projects and would like to present at the seminar.
The second half of the seminar focussed on… »
ET-seminar 2011-12-09: Using Multiple Instance Learning for Event Detection in Eye Movement data
At today’s seminar Henrik Blidh presented his master thesis in mathematical statistics entitled ‘Using Multiple Instance Learning for Event Detection in Eye Movement data’. Like Linnea Larsson’s seminar a few weeks ago, Henrik’s thesis targets the detection of blinks, fixations, saccades, smooth pursuit, and glissades, but, unlike Linnea, Henrik approaches the problem from a machine… »
ET-seminar 2011-12-02: Detection of lesions in zoomable microscopes using eye tracking
At today’s seminar, Thomas Jaarsma and Halzska Jarodzka presented a planned study where the eye track physicians who diagnose lesions from x-rays using a zoomable microscope. Most eye-tracking studies of the medical diagnosis process have worked with still images, often x-rays of chests or mammograms. Working with zoomable images introduce many new challenges, just like… »
ET-seminar 2011-11-25: Detection of saccades and glissades in ET data
Todays seminar discussed event detection in eye-movement data, a topic that is of extreme importance to all research that uses the durations, amplitudes, velocities etc. of fixation, saccades and all the other events. Contrary to popular belief, the detection and measurement of these events is far from a solved issue, and all current commercial algorithms have… »
ET-seminar 2011-11-21: Watching you watch movies: Using eye tracking to inform film theory
Tim Smith gave a very inspiring talk about how film editors already had established the principles for editing in the 1920s. Now we can examine these conventions and rules of thumb, and surprisingly Tim found that they were basically all correct. Film editors know how to manipulate viewer gaze to make sense of continuity. This feeling… »
ET-seminar 2011-11-18: Visual segmentation of images. Can we test semiotic theories with eye-tracking?
Today, Jana Holsanova, co-editor of Visual Communication, presented the draft of a paper that compares the semiotic analysis of how an image is read to eye-movement data. Previous studies from the eye-tracking group have shown that semiotic theories can be tested, and today’s discussion focussed on how the two theoretical frameworks compare, and whether further… »
Eyetracking on the science show of national Swedish Radio
