We've gone through a minor branding and logo updating exercise to enhance our brand and image. Here's the new Gazepoint logo. Hope you like it!
The latest update to the Gazepoint software is out. This version fixes a few minor bug and implements cursor click tracking in screen capture mode. To date we've been able to track clicks within Gazepoint Analysis (images, video, web pages) but were unable to track left click/right click in other programs (such as screen capture). We are happy to announce we've upgraded the tracking capability to capture left clicking and right clicking (both mouse down and up). In the Gazepoint API the cursor state value CS now corresponds as follows: 1 = left mouse button down 2 = right mouse button down 3 = left mouse button up 4 = right mouse button up. In Gazepoint Analysis, visualization of left mouse button data is highlighted with a green square centered on the click location and visualization of right mouse button data is highlighted with a red square centered on the click location.
Blink tracking has been added to the latest release of the Gazepoint software (V3.0.0), both to Control via the Open Gaze API (all versions) and to Analysis visualizations (UX). In Control you can access the blink tracking metrics by enabling the ENABLE_SEND_BLINK setting which adds a blink counter BKID, blink duration for the last blink BKDUR and the average blink rate over the last minute BKPMIN. In Analysis simply click the Enable display button for the Blink Rate to turn on the overlay.
The Gazepoint Remote Viewer provides the ability to transmit the images shown in the Gazepoint Analysis software, over a network, to a remote computer for unobtrusive observation of the experiment underway. The core features of Remote include: Transmission of Analysis images to remote computers over a TCP/IP network High quality images and low bandwidth requirements Control of experiment underway (Start / Stop / Next media item) Remote chat between multiple Remote clients Real-time event logging in the experiment by Remote clients Full screen viewing We quietly introduced the Gazepoint Remote Viewer late last year and over the last months collected feedback on the performance of the system. We originally provided the ability to tune the quality of the image (low to high) to vary the level of bandwidth required. The feedback was a resounding, "Give us the highest quality images at the maximum frame rate with minimum bandwidth!", so we completely redesigned the underlying video feed protocol. The latest release is able to transmit high quality images at 10 frames per second (fps), using approximately 20 Mbps, easily within a 100 Mbps local area network. The bandwidth/frame rate will depend somewhat on the content being shown to the user (how much image compression is possible) and the underlying network speed. While a LAN (100/1000 Mbps) connection is best, the system will still operate over a lower bandwidth connection such as WiFi or the Internet (WAN), the frame rate may just be lower. Remote provides the ability to remotely start the recording of the experiment, move the recording to the next media item to be tested, as well as to stop the recording. This can allow the experiment subject full control of their computer (keyboard and mouse), while the [...]
I recently looked back at our blog and the last post was in February! It's been quiet on the website but we have not been idle, we have a whole set of new features and products we'll be rolling out over the fall. We've just posted V3.0 of the Gazepoint Software suite, I'll take you through a few of the new features in the next set of blog posts.
Gazepoint has been covered in the news a fair amount recently. After coverage in the local Vancouver Sun newspaper, Dr. Hennessey has given interviews on CKNW radio (SoundCloud link below) as well as CTV on eye-tracking applications and even given a sneak peak at our head mounted prototype system. We have also added another 3 citations of the Gazepoint GP3 in academic papers to the publications page.
Gazepoint's affordable and easy-to-use GP3 means you can outfit an entire classroom with eye-trackers! Leading eye tracking expert Dr. Andrew Duchowski of Clemson University, set-up a classroom with a GP3 eye tracker and Gazepoint Analysis software on each desk for the Fall 2014 school term. Dr. Duchowski teaches eye tracking from the low level systems to end-use applications, and found that sharing a limited number of devices between students really limited their exposure and first -understanding of how eye trackers works and are best used. With the help of Gazepoint, problem solved! With an entire laboratory facility instrumented with eye trackers and eye tracking software tools, it became much faster and easier to teach core concepts and have the students gain practical hands-on experience with running eye tracking studies. A total of 20 workstations were instrumented with GP3 desktop eye trackers attached to 22" displays with the VESA mount adaptor. The VESA mounts ensure the GP3 is solidly affixed to the workstation, while also properly positioning the eye tracker with respect to the viewer. Each workstation ran a full version of the Gazepoint Analysis UX software. "Teaching the class with 20 eye trackers, with one per student, was liberating. Contention issues were all but eliminated. A portable eye tracker on a tripod in front of the lectern with the instructor's display projected on the screen allowed a hands-on demo where each student ran their own calibration and their own first mock study with an image as stimulus. Prior to the instrumented classroom, students would often procrastinate with this kind of experimentation, jeopardizing their potential for success later in the semester. The in-class hands-on demo allowed each student to quickly grasp how to calibrate the device, record data, and then immediately see how scanpaths and heatmaps correspond to what they had [...]
A New Year is upon us and we're happy to unveil a faster, improved website! We heard from many of our valuable customers that they were experiencing trouble with our online shopping cart, so we went to work and we now have a much faster site and a new cart which should work much better. In the process of updating the site, we also reorganized the shop to greatly simplify the discount bundles. You can now customize a bundle with exactly the products and accessories you'd like while still getting the discounted price! If you notice any issues with the new system or have any difficulties, please let us know. Wishing all of you a happy, successful, and productive 2015! From the whole team at Gazepoint
We are frequently asked if we can point to academic papers that illustrate the use of the GP3 eye-tracker and Gazepoint Analysis. Academic papers take a considerable time to go from experimentation to publication, but we are very happy to have the first set of published works using our system available for reference (listed below). We will maintain an up to date list of these external publications HERE, along with our own historical and future publications (yes we use the Gazepoint system in our own research!).

Once again another software update! And this time with more features! And yes more bug fixes too! The browser bar of the integrated browser has been minimized, the age/gender sort selection improved, and by popular demand we have added the ability to mask off low viewed data when visualizing large datasets to the data visualization control. We were hearing that when very large numbers of recordings were aggregated (100's) it turned out there were gaze views at pretty much ALL portions of the screen. And while technically correct, the visualization ended up covered in blue with a few 'hotter' regions. The data visualization dialog box now lets you threshold off low viewed regions, highlighting the regions of the image viewed most by the aggregate of viewers. This thresholding technique can also be used on fixation maps to hide fixations with small durations. Heat Map with most of image viewed Heat Map with highest viewed regions emphasized Fixation Map with all fixations Fixation Map with fixations of small duration removed Summary of updates: - Improved multi-recording selection based on gender and age - Added ability to hide low viewed regions of heatmap (Outlier Filter) - Added ability to hide low duration fixations in fixationmap (Outlier Filter) - Reduced size of browser controls for web browser experiments - Bug fix for use of browser forward / back buttons if there is no browser history created yet - Bug fix in preventing all data records from being deselected when a recording setting is changed - Bug fix in reset of CNT and TIME variables when switching to next media item - Bug fix in audio recording setup of Thinkaloud - Bug fix in recording web media, escape button [...]
