EL-MAR's Fixation Analysis Software Technology (FAST) provides quantitative
information regarding the subject's fixation and scan-path patterns from
data recorded by EL-MAR's systems. FAST dramatically reduces the time
and effort required for data analysis and runs on a low-cost personal computer
under the Microsoft Windows operating system. With FAST, all input, analysis,
data management and reporting functions are accomplished through easy-to-use
graphical-user-interfaces. Standard reports include graphs and tables of
fixation data and pictorial views of the subject's scanning behavior.

Data Management
- Set-up, analysis and reporting functions are accomplished through easy-to-use
graphical user interfaces.
- The PARADOX relational-database software package is used to support data
entry, reporting and interactive query generation.
- The database allows the association of: multiple subjects with each study;
multiple tests with each subject; and multiple ojects-of-interest with each test.
Each test can be associated with a specific event or procedure.
Data Analysis
- Software control of VCR functions facilitates automated data analysis.
- Objects-of-interest are interactively selected from a video-image of the scene.
- Coordinates of objects-of-interest are calculated at a rate of 30 times/second.
- Eye-position and objects-of-interest coordinates are synchronized and recorded
to hard disk. Pupil-diameter, timeline information, event markers and data from
six digital channels are also simultaneously saved.
Reports
- Graphical, tabular and pictorial reports include:
- The distribution of fixation points in the field-of-view.
- The scan-path pattern within the field-of-view.
- The duration and frequency of fixation on each object-of-interest.
- The scanning order for each object-of-interest (relative to a specified event).
- For multiple subjects, statistical summaries of the duration and frequency of
fixation.
- Subject selection for statistical summaries is based on user defined classification
structure.
- Custom analysis and reports are easily generated.
- Data can be exported to ASCII files for use with other software packages.
