Eye Tracking Benefits Study of Coordination
The visual system has been called the “queen of the senses” due to its supervisory role over whole body coordination. The analysis of eye movement is important when dealing with body movement tasks.
The new ETMobile eye tracking glasses solution with its sleek and comfortable design is the perfect choice when participants must be able to move freely with an unobstructed view. The entire system fits into the ETMobile canvas bag for easy transportation.
Your participant wears the lightweight eye tracking glasses and recorder/transmitter. The ETMobile software is intuitive with automated steps. Within minutes you are viewing real time gaze information. The adjustable eye tracking optics also include a microphone for audio collection.
The eye and scene images are wirelessly transmitted from the recorder/transmitter device to the ETMobile laptop. You can also store the data on an SD card which typically records about 90 minutes of data.
In real time, you can view the participant’s gaze over the scene image, providing immediate insight into the participant’s response. Synchronization with other devices, such as force plates, EEG, EMG, etc. is available.
Eye Tracking with Motion Capture
Perception and motor system interaction is especially important when studying task performance in balance impaired and/or visually impaired populations such as those with multiple sclerosis, Parkinson’s disease or cerebral palsy.
To assist in your analysis of such tasks, Argus Science has partnered with the leading 3D motion capture systems to provide accurate point of gaze location data in your lab coordinate system.
ET 3Space
Argus Science ET 3Space will receive real time, six degrees of freedom head position information from the selected motion tracker.
ET 3Space can calculate point of gaze on up to 20 surfaces of interest. Typical surfaces include treadmills, wall, floors, stairs and well as other stationary displays.
A simple procedure, using the ET 3Space and environment mapping tools, quickly defines each surface in your environment.
Using data from a motion capture sensor attached to the eye tracker head gear, the ET 3Space will actually solve the 3 dimensional problem of finding the line of gaze vector in space and solving for its intersection on each of your defined surfaces.
Valuable Data Analysis
The ET 3Space data include identification of the scene surface being viewed, coordinates of the gaze point on that surface, head position and orientation, the distance of the eye from the spot being fixated, position of the eye in space, direction of the gaze vector, and pupil diameter. This digital data can be exported as a text file or to Excel. Using Argus Science analysis software with the ETMobile and ET 3Space data, each of your identified surfaces can be processed to match fixation data with your specified areas of interest.
Argus Science offers the a wide selection of graphical displays of gaze including: total engagement times within an area of interest, time to first fixations in an area of interest, number of fixations within an area, and average pupil diameter in each area.
Capture a high quality digital image of your environment and have individual or multiple participant data applied over the image. Engagement data can be fixations, heat maps and gaze trails.
