Research Description

If we are to successfully interact with the world around us, our visual system must do two important things : recognize objects and assist in the programming and control of actions directed at those objects.

Dr. Marotta's research goals are directed at offering a better understanding of the functional architecture of visual perception and the visual control of action. By utilizing a multi-disciplinary approach that includes neuropsychological patient investigations, fMRI, traditional cognitive and psychophysical methodologies and advanced 3D visuomotor paradigms, Dr Marotta's research has helped address one of the fundamental questions in Cognitive Neuroscience - how sensory information is transformed into perceptions of the world and useful motor acts.

Public/Media (Non-Technical) Description

While great strides have been made in the study of the human visual system, we still have a long way to go in our understanding of object recognition and visuomotor control. The specification of a detailed model of the visual control of human grasping will not only provide us with critical insights into the functional architecture of this important human skill, but will also assist in the development of more efficient control systems for robotics, tele-operations, and tele-assistance. This is particularly true when the relevant features of a goal object or task have to be specified without assistance from the operator (i.e. devices for the blind or physically impaired). Ultimately, this research will lead to the development of neuro-prosthetic devices capable of restoring vision or mobility.
