  • I promised myself that the Visualist will be a far broader forum than a traditional “corporate blog”, but this one I have to share.  We recently released a new version (2.1) of our flagship display auto-calibration software, Sol, and it contains a feature worth mentioning – wide field of view lens correction. To automatically align a cluster of projectors into a single display palette, you need to use a sensor of some kind. In the case of our software, we use a camera. Point the camera at the display, start our software, and after a few minutes, any overlapping set of projected images ...Read More »

  • How much of a display is physics and how much of it is computation? Certainly some parts are physical hardware components. Broadly, the minimum requirements of a display are a light source of (even if that light source is ambient), a mechanism for modulating the intensity and color of that source. For example, the tiny mirrors of a DLP chip that control how much light reaches the viewer’s eye and a spinning color wheel, and optics to direct the colored rays of light to the viewer.  However, beyond these foundational components, other aspects of display are based on computation and those can be ...Read More »

  • Welcome to the Visualist. The Internet is already full of technology-oriented blogs that vary in sophistication from angry rants about consumer electronics to insightful commentary about the ongoing technology dialog. So, why another blog? I work in an area known by a variety of names including computer vision, visualization, human-computer interaction, and computer graphics. Surprisingly, other than academic journals, there is very little generally available that covers these fields. It is also something I am really passionate about. There are plenty of exciting, innovative, and surprisingly impactful developments in the world of visualization and interactive graphics that fly under the ...Read More »
