Eye Tracking Data in Multimedia Containers for Instantaneous Visualizations

ETVIS16 - Demonstration Video and Datasets

Nowadays, the amount of gaze data records of subjects associated with video sequences increase daily. These eye tracking data are unfortunately stored in separate files in custom-made data formats, which reduces accessibility even for experts and makes the data effectively inaccessible for non-experts. Consequently, we still lack interfaces for many common use cases, such as visualization, streaming, data analysis, high level understanding, and semantic web integration of eye tracking data. To overcame these deficits, we want to promote the use of existing multimedia container formats to establish a standardized method of incorporating content videos with eye tracking metadata. This will facilitate instantaneous visualization in standard multimedia players, streaming via the Internet, and easy use without conversion. Using our prototype software, we embed gaze data from eye tracking studies and the corresponding video into a single multimedia container, which can be visualized by any media player. Based on this prototype implementation, we discuss the benefit of our approach as a possible standard for storing eye tracking metadata including the corresponding video.

Source code

VLC 3.0.0 patch

Modified version of the subsusf.c. Necessary for the playback of the USF files.

USF to ASS translation

XSL file for USF to ASS translation usf2ass.xsl.

Eye tracking data to USF converter

Currently, the eye tracking data to USF converter is only available as command line implementation. A version with a user interface is planned to release in the upcoming months. If you want to get the source code of the command line converter nevertheless, please write an email to Julius Schöning.

VLC Visual Analytics Plugins

To install the extensions under Linux, please copy the SimSub.lua and/or MergeSub.lua into ~/.local/share/vlc/lua/extensions/ for the current user or /usr/lib/vlc/lua/extensions/ for all users.

SimSub: Visualization of different eye tracking datasets in multiple windows
MergeSub: Visualization of different eye tracking datasets in a single window

Converted Eye Tracking Data Sets with Instantaneous Visualizations

The following data sets are provided for research purposes. By using these data sets in the proposed multimedia container format, please cite [S], [S1], [S2], or [S3] and also the original dataset [A], [B], [C], [K], or [R].

K7 07.png Kite
ASS
USF
Person on a meadow steers a kite. The kite repeatedly leaves the field of view. Follow the flight path of the kite if possible. Smooth pursuit if the kite is visible. Otherwise, the participants either tried to estimate the position of the kite, or focused on the person.
K8 08.png Case-Exchange
ASS
USF
Various persons crossing the field of view while a text ribbon in the lower part is showing further information. Task is provided by the text ribbon: Look for metal case. Attentional synchrony on the text ribbon until the metal case appears and the task is readable.
K9 09.png Ball Game
ASS
USF
Three players with orange shirts and one player with a white shirt pass a ball around. Task group A: Count ball contacts of the white player. Task group B: Count passes between orange players. Attentional synchrony often on the ball, independent from the task.
K10 10.png Bag Search
ASS
USF
Various persons carrying different bags are crossing the field of view. Look for a specfic bag. Two groups: two different search targets, presented before the video started. Switching focus on new bags in the scene. Depending on the group, the search targets attract more attention.
K11 11.png Person Search
ASS
USF
People with different clothing cross the field of view. Task group A: Find the person with a hooded sweater. Task group B: Find the person with a red shirt and a headgear. Switching focus on new persons. After identification, search targets become less important than new persons.
