Test (in Czech) - data acquisition module

Demo version of test and sample data (in English)

Data acquisition module - 3D scene visualization have to be turned on and off using the F2 key.
Connecting module - use sample data about virtual camera movement (as first step) and from eye-tracking system (raw data or fixations, as second step). You must choose right type of data from eye-tracker (EyeTribe in case of sample data) and right type of data (raw or fixations).
Connecting module for generic eye-tracking data. Generic data is simple CSV file (tab delimited, first row are contains names of columns) with three columns - time (in miliseconds) and screen coordinates (X and Y). Example of generic CSV file is available here. Use data about virtual camera movement from previous paragraph.
Calculating module for generic CSV data and raw data (from SMI Red or EyeTribe) and calculating module for fixations (both SMI Red and EyeTribe) - sample of connected generic data, raw data and fixations. These files are sources for calculation, they must be load in corresponding variant of calculating module. Same screen resolution as during the data acquisition, which was 1600 x 900 px, must be set for a correctly calculated result.

Data validation

Acquisition module for data verification - 3D scene visualization have to be turned on using the F2 key. 3D scene is displayed as an animation. Animation stops automatically at the end.
Calculating module for data verification. Same screen resolution as during the data acquisition must be set for a correctly calculated result.
