Chiasm vs OGAMA

Chiasm captures gaze data through participants’ webcams for remote online studies and research. It processes webcam frames in real time and produces timestamped gaze coordinates linked to study events, together with session metadata. Researchers can connect it to Qualtrics, jsPsych, or custom web studies through a JavaScript library. Chiasm says studies can include hundreds of participants at once. Researchers can download gaze data from Chiasm or stream it to their own server; when used with platforms such as Qualtrics, data is held on Chiasm’s servers for later export. Webcam video is not stored by default, though limited calibration or validation recordings may be retained with explicit opt-in consent. The service supports Google Chrome on laptops and desktop computers with webcams. Flex has no monthly minimum and costs €0.25 per minute. Starter is €199 per month with 900 participant-minutes included, and Pro is €499 per month with 3,000 participant-minutes included. A 7-day trial is listed.

OGAMA is Windows freeware for recording and analyzing eye-tracking and mouse-tracking data in slideshow experiments. It supports direct recording with Tobii, alea and SMI systems, along with the open-source ITU Gazetracker solution. Gazetracker can use infrared-ready webcams or a modified PlayStationEye camera. OGAMA can also import ASCII recordings from eye-tracking and presentation software or hardware. Its analysis tools include database-driven preprocessing and filtering, attention maps, areas of interest, saliency calculations, Levenshtein distances, and replay with AVI recording. Output can be used directly with statistical software packages. OGAMA is an open-source project written in C#.NET, and users can adapt its code. The maintainer announced in May 2016 that they had stopped supporting the project because they no longer had time for support and feature requests.
