Neurocognitive investigations of human eye movements: Interaction between levels Current Research Interests TWO VISUAL SYSTEMS AND THEIR EYE MOVEMENTS Parameters of eye movements as a means of identifying processing in ambient and focal modes. Modes of processing in static and dynamic stimuli. two visual systems 1. Theoretical and Basic Research

Neurocognitive investigations of human eye movements: Interaction between levels Functional differences of fixations 1. Ambient Processing is related to simple visual properties such as motion, contrast and location Processing is characterized by short fixations within long saccades 2. Focal Processing is responsible for object identification and its semantic categorisation Processing is characterised by long fixations within short saccades

Neurocognitive investigations of human eye movements: Interaction between levels PERCEPT –European NEST PATHFINDER project (led by our team) Objectification of how we perceive complex visual material. Integrate information from fMRI, NIRS, EEG/ERP and MEG and new approaches in parallel eye movements analysis using EFRP and FIBER techniques. Attentive, intentional and emotional states are visualised as an interpretation map.

Neurocognitive investigations of human eye movements: Interaction between levels visual distractors - visual change leads to a prolongation of fixation duration Distractor effect – occulomotor reflex or orienting response?

Neurocognitive investigations of human eye movements: Interaction between levels Eye Movements and Social Interaction Virtual characters are capable of inducing physiological reactions and emotional experience in human observers. Visual attention was more intensely allocated to direct gaze and potentially threat-relevant facial configurations. Relationship between the character’s expression, the observers facial movements and their subjective feeling suggests an empathic response.

Neurocognitive investigations of human eye movements: Interaction between levels Investigation of individual differences and eye movements Individual differences in eye movements in the normal population Eye movements of clinical groups, Williams Syndrome. Levels of processing in Williams Syndrome. Physiological evidence of two visual systems and their eye movements.

Neurocognitive investigations of human eye movements: Interaction between levels 2. Practical Applications of Eye Tracking Therapeutic applications; COGAIN, Amblyopia. Amblyopia; In conjunction with AIF. –using eyetracking while viewing a 3D environment –Shutter glasses to present visual information selectively to each eye –Therapeutic effect for sufferers of Amblyopia

Neurocognitive investigations of human eye movements: Interaction between levels Industrial Partners BMW – Investigation of attention in dynamic environments; attention and hazardous events. Daimler-Chrysler – virtual environment for video conferencing Daimler Chrysler

Neurocognitive investigations of human eye movements: Interaction between levels Are there changes in eye movement parameters relative to hazard events? Two visual systems in dynamic environments

Neurocognitive investigations of human eye movements: Interaction between levels Videoconferencing Gaze based selection Joint attention Daimler Chrysler

Neurocognitive investigations of human eye movements: Interaction between levels ZOOM Future Optical Microsystems Development of a gaze controlled, see-through Head Mounted Display based on a CMOS-OLED Interface - HMD by Microvision and the EyeLink I eye tracker Development of a simulation system integrating commercially available HMD and Eye Tracker specify hardware and software requirements of gaze controlled HMD and assess usability

Neurocognitive investigations of human eye movements: Interaction between levels Collaborative Research Possibilities We are open to collaboration on all basic research in the theoretical aspects of attention and cognition both in the normal population and in clinical groups. We also welcome collaboration on practical applications of eyetracking technology, particularly to usability and human-computer interfaces. We particularly invite COGAIN partners to collaborate with us on the establishment of a TC within CIE to investigate safety issues in eyetracking.
