We recommend that a measure of pupil dilation be kept as meta-data for every iris code. Also, the absolute dilation of the two images, and the dilation difference between them, should factor into a confidence measure for an iris match....
One area of the eyes that cannot be faked is pupil dilation. When stressed, your pupils may naturally dilate as part of the body'sstress response. Blinking frequently can also subconsciously occur. In this way, the eyes may be a clue about a person's true thoughts or feelings that are n...
For the first part, the robot guessed which one of the six cards a person described deceptively. The robot successfully detected the card described deceptively with an accuracy of 88% by computing the mean pupil dilation during each card description and then choosing the card with the highest di...
Measures of pupil dilation and reaction time to the probes were also obtained. In Experiment 1, we found that subjective ratings of presence increased ... T Troscianko,TS Meese,S Hinde - i-Perception,3,7(2012) 被引量: 22发表: 2012年 Reaction Injection Molding: Filling of a Rectangular ...
The pupil-dilation times of participants assigned hard tasks fell off significantly as the experiment progressed.During the experiment the scientists used a technique called magnetic-resonance spectroscopy to measure biochemical changes in the brain. In particular, they focused on the lateral prefrontal ...
Epinephrine is known to activate the central nervous system, increasing the heart rate, causing pupil dilation, and creating an overall more activated state (if you’ve ever had an “adrenaline rush” then you know what the effects are like). The participants were then placed in a waiting roo...
It’s important to remember that cursor movement doesn’t always align perfectly with where users are looking, which can lead to misleading insights. Eye-tracking website heatmaps Eye-tracking heat maps user sensor technology to track users’ eye movements, blinking, and even pupil dilation as ...
engineering graduate students to assess two building facades while wearing Tobii eye-tracking glasses. The glasses have two cameras to measure movements and positioning simultaneously. One camera faces the object, and the other is trained on the user's eyes to measure pupil dilation and gaze ...
Here we used an associative threat learning task in a relatively large sample (n = 144), to assess the relationship between self-reported IU and exposure experience on safety-learning and safety-retention. We measured skin conductance responses, pupil dilation and expectancy ratings whilst participant...
