One of the least intrusive methods for assessing cognitive load is measuring pupil diameter change using remote eye tracking. Because of the effect of task evoked pupillary response (TEPR), the pupil will dilate when a person is faced with a challenging cognitive task. But the pupil’s diameter will also change due to change in lighting …

In most of our experiments here at Project54 we incorporate eye tracking. It is useful, not only to be aware of where a subject is looking, but it can also measure pupil diameter which is an indicator of cognitive load. Over the years we have simply discounted unreliable data. Most of that unreliable data is …

Alongside other Project54 members in November I visited the 2010 AutomotiveUI Conference held at Carnegie Mellon University in Pittsburgh, PA. This time I presented a poster about our research on the effects of illumination and cognitive load on pupil diameter. The abstract to this poster can be found here. The poster session was very successful. …

Amongst the many metrics that an eye tracker generates, pupil diameter as a metric has grabbed the attention of many eye tracking researchers. It is well known that the pupil diameter changes with respect to stimuli such as pain, arousal, auditory signals, cognitive demands and illumination etc. As an intern at the Project54 lab at …

In a world where technology is everywhere – from the common uses of cell phones, driving electric powered vehicles (Hypercar),space exploration, and even having an operation performed solely by robotic arm – machines have become dominant in society. At the turn of the century, Eye Tracking became the leading invention in technology. Now Eye tacking is …
