Research Summary

We pursue a number of related programs of research as follows:

Visually guided reaches-to-grasp: We study both feedforward and feedback control of reaches-to-grasp. The former entails investigation of calibration of space perception (i.e. perception of object distance, size and 3D shape), of 3D shape perception, and of the perception of affordances for grasping. The latter involves discovery of the visual information used to guide reaches online and modeling the dynamics of such control. We have most recently studied reaching in the context of walking-to-reach, a problem that entails coordination of nested actions. Most recently, we have studied the control of grasping in the context of a model of the affordances for grasping and adaptation to changes in grasp effectivities (naturally caused by growth, aging, or injury).

Developmental Coordination Disorder: We are working to develop automated means to train and improve manual control by children with Developmental Coordination Disorder, with the specific goal of improving their handwriting. We are using haptic force feedback devices coupled with computer graphics/virtual reality technology to create a manual task at which the children train with parametric levels of support that enables them to gradually improve their performance while maintaining high levels of self-efficacy.

Human bimanual and visual coordination: We have developed a nonlinear coupled oscillator (dynamical systems) model of rhythmic coordinated movement that incorporates perceptual information variables in the coupling of the coordinated movements. The research program entails investigation of these sources of information in visual and haptic control of these actions. The research has extended to the learning of new coordinated movements through perceptual learning (developing sensitivity to new information variables). Most recently, this latter effort has been extended to study of perceptuo-motor learning across the lifespan to discover how rates of learning change over the lifespan with applications to treatment of stroke and other related disorders.

Calibration: In the 1990's, we advocated that calibration should be investigated as the solution to problems in space perception. We have developed a theory of calibration as entailing a mapping among embodied units of perception and action. We have performed extensive studies investigating this theory and the resulting dynamics of calibration.

Affordances and long distance throwing: We have investigated the ability to perceive by hefting the optimal objects for throwing to a maximum distance and how the ability to do this is acquired in concert with acquiring throwing skill. We discovered that the affordance property exhibits the same functional relation between object size and weight as in the classic size-weight illusion. Accordingly, we have hypothesized that the classic illusion actually reflects uniquely human readiness to throw. The research program has now been extended to studies of targeted long distance throwing and visual guidance thereof.

Visual event recognition: We have investigated the visual information used to recognize events, performing extensive psychophysical studies testing sensitive to qualitative variations in trajectory forms. We have approached events as spatial-temporal objects of perception.
