Travel gaze? Re-examining gaze behavior during locomotion

On Foveated Gaze Control and Combined Gaze and Locomotion Planning

This chapter presents recent research results of our laboratory in the area of vision and locomotion coordination with an emphasis on foveated multi-camera vision. A novel active vision planning concept is presented which coordinates the individual devices of a foveated multi-camera system. Gaze direction control is combined with trajectory planning based on information theoretic criteria to pr...

Atypical Gaze Behavior in Children with High Functioning Autism During an Active Balance Task

Background. Unusual gaze behavior in children with autism spectrum disorder (ASD) was reported very early in the literature. Objectives. The current study examined gaze behavior in children with ASD and typically developing (TD) children while performing an active balance task on the Wii balance board. Methods: 8 children (male) diagnosed with high-functioning ASD and 9 TD children (3 female, ...

Influences of state anxiety on gaze behavior and stepping accuracy in older adults during adaptive locomotion.

OBJECTIVES Older adults deemed to be at a high risk of falling transfer their gaze from a stepping target earlier than their low-risk counterparts. The extent of premature gaze transfer increases with task complexity and is associated with a decline in stepping accuracy. This study tests the hypothesis that increased anxiety about upcoming obstacles is associated with (a) premature transfers of...

Gaze shifts and fixations dominate gaze behavior of walking cats

Vision is important for locomotion in complex environments. How it is used to guide stepping is not well understood. We used an eye search coil technique combined with an active marker-based head recording system to characterize the gaze patterns of cats walking over terrains of different complexity: (1) on a flat surface in the dark when no visual information was available, (2) on the flat sur...
