Taprav (Task Aligned Pupil Response Analysis and Visualization) is a visualization tool that enables the exploration of a hierarchical task model representation aligned with pupillary response data.
Software packages that ship with commercial eye trackers fall far short of what researchers need to analyze pupillary response data for interactive tasks. Existing analysis software does not provide a tightly synchronized view of the user task model, video of on-screen interaction, and pupillary response. We offer a pragmatic visualization solution that fulfills these needs along with a user interface that encourages exploration with focus and context perspectives. In addition, although designed with pupil response analysis in mind, the architecture of Taprav has been designed to support any temporal coherent dataset measured during task execution.
Taprav will run on any system where the Java Runtime Environment is installed. The application itself is built on J2SE 1.4.2. The most recent JRE can be downloaded Here.
Although not necessary for the various basic visualization features of Taprav, if you intend view video synchronized with the pupil and task model data you will also need to have QuickTime for Java installed on your machine. Currently, this means that only systems running Windows or MacOS will be able to play video through TAPRAV. Instructions for installing QuickTime for Java can be found here.
