iTrace directly supports many software engineering tasks by providing the following features.
The iTrace Core is responsible for managing all aspects of the physical eye tracking devices. It also maintains the session state and maintains any gaze related data files produced during the study. Lastly, the core assists with plugin management indicating when to start and stop recording information in the IDE. The most current release supports Tobii Pro and 4C (with pro upgrade) eye trackers, GazePoint trackers, and the Smarteye trackers. It is designed to add new tracker support fairly easily. The core also is able to display a recticle of your current gaze to check calibration accuracy.
The current plugins supported are Visual Studio, Eclipse, Atom, and the Google Chrome web browser. The Plugin in capable of converting screen gaze positions supplied by the core to specific text and interface elements contained with the IDE. The plugin also features the ability to enable an on-screen gaze cursor to show where a participant is looking within the IDE.
When a session is finished the core and plugin will both produce a set of recorded data about the study in XML format. The response records are joined by the event-id field in each gaze response record.
iTrace presently supports three fixation filtering algorithms performed as an offline post processing phase using iTrace Toolkit The current fixation algorithms supported are:
Output from iTrace is intended to be generic enough for any type of task. To support researchers working in specific areas such as program comprehension, iTrace Toolkit supports mapping raw gazes and fixations to syntactic and token information derived from source code written in C, C++, C#, or Java. iTrace toolkit provides the complete toolchain for generating the fixations and the token mapping from the raw gaze generated from the plugins. iTrace Toolkit is not a statistical application. You can export the fixation data you need and perform statistical tests in your favorite statistical package.
