Combining wearable eye-tracking with 4π light-field measurements: towards controlling all bottom-up and top-down factors driving overt attention during real-world tasks

For improvement of office space design, we intend to capture the full (4π) light-field of an office space, while measuring gaze, head direction, body position, blink rate, and pupil size along with task performance and subjective well-being during a variety of office tasks. Besides the immediate application aspects this will allow for the first time to have full control over task and visual input in a fully unconstrained real-world setting. In the study reported here, 52 participants performed office tasks that varied in the tools used (phone, computer, paper ) as well as in their mental load – input, output, reflection and interaction – and were recorded under various experimentally controlled lighting conditions and outside views. We analyze gaze allocation during these tasks, with a particular emphasis on the distinct roles of eye and head, as well as on the effects of discomfort glare.
