About:

Mary is a faculty member of both the Computer Science Department and the Brain and Cognitive Science Department where she serves as one of the heads of the Center for Visual Science. Mary's interests include the study of eye movements in natural tasks, visual memory, and the coordination of body movements in natural taks.

Research Interests:

Vision naturally occurs in the context of voluntary information gathering movements involving the eyes, head, and hand. However, much work in vision is dominated by trying to understand the events occurring within a single view of a scene, and we have only limited understanding of the consequences of eye and head movements for vision and visuo-motor coordination. The technology to look at performance in more natural circumstances now exists, and I am currently developing a human sensory-motor lab, in collaboration with Dana Ballard in Computer Science, for measuring unconstrained eye, head, and hand movements in the performance of natural tasks, and for developing a virtual reality display to allow controlled but visually complex stimulation. We also have the capability of providing force feedback for two finger grasping. The new instrumentation allows a large range of experiments not previously possible. My objective is to understand the demands placed on vision and motor systems by natural behavior and the nature of the representations that are required for visually guided tasks.

Projects:

Examining Task Context and Prior Knowledge During Naturalistic Tasks: Little is known regarding what visual information is selected and retained when guiding behavior. We test the hypothesis that acquisition and retention of visual information is governed by task relevance. Preliminary data suggests that immediate task demands govern the precise composition of visual working memory, the contents of which may be aggregates of task relevant features.

Behavioral Effects of Varying Eye, Head, and Hand Temporal Coordination Sequences in a Natural Task: This experiment seeks to examine the role of planning or "look ahead" fixations in natural tasks and how the scene information transferred across saccades may influence eye, hand, and head coordination.
