Abstract

The deployment of human gaze has been almost exclusively studied independent of any specific ongoing task and limited to two-dimensional picture viewing. This contrasts with its use in everyday life, which mostly consists of purposeful tasks where gaze is crucially involved. To better understand deployment of gaze under such circumstances, we devised a series of experiments, in which subjects navigated along a walkway in a virtual environment and executed combinations of approach and avoidance tasks. The position of the body and the gaze were monitored during the execution of the task combinations and dependence of gaze on the ongoing tasks as well as the visual features of the scene was analyzed. Gaze distributions were compared to a random gaze allocation strategy as well as a specific "saliency model." Gaze distributions showed high similarity across subjects. Moreover, the precise fixation locations on the objects depended on the ongoing task to the point that the specific tasks could be predicted from the subject's fixation data. By contrast, gaze allocation according to a random or a saliency model did not predict the executed fixations or the observed dependence of fixation locations on the specific task.

Each is checked against this paper’s own text: does it say what the citing paper says it does?

  • The value of an eye movement lies in reducing uncertainty and increasing the expected reward (probability of success) of a future action.

    “An alternative explanation however emerges from studies of eye movements in natural behaviors, which suggests that the value of an eye movement lies in reducing uncertainty and increasing the expected reward (probability of success) of a future action (Ballard and Hayhoe, 2009; Hayhoe et al., 2012; Rothkopf et al., 2007; Tatler et al., 2011).”

  • A model-free prediction error mechanism can be prohibitively slow in complex tasks and may erroneously assign credit to irrelevant steps.

    “Such a mechanism can be prohibitively slow in complex tasks, and may erroneously assign credit to irrelevant steps (e.g., value the earlier decision to study for a final exam less than the more recent decision to wear a white shirt) (Rothkopf et al., 2007).”

About these checks

Registry, retraction, Cites and statistics results are computed, not judged, with one exception: a printed reference that no index lists is read once by a model before it counts as a citation error. Claims are extracted by a model and kept only when their quote appears verbatim in the text; each cited source is then checked, with a model’s help, for whether it says what the claim relies on. Those verdicts can be wrong — read the claim’s quote and the cited source before relying on one.

Statistics and arithmetic are recomputed, not judged.

Confidence bands are shown only for fields calibrated on our annotated test set. None is calibrated yet, so no band is shown.
