At long last I had the opportunity to try out the CastAR, a glasses-based Augmented Reality system developed by Technical Illusions. The hardware has been in the works now for a couple of years, but every time we have come across a demo we were thwarted by the long lines that accompany them. This time I was really lucky. [Jeri] gave us a private demo in a suite at the Palazzo during CES 2015. Reflecting on the experience, CastAR is exactly the type of Virtual Reality hardware I’ve been longing for.
[Jeri, Rick and the Technical Illusions crew] have taken the castAR to Kickstarter. We’ve covered castAR a couple of times in the past, but the Kickstarter includes a few new features just ripe for the hacking. First, castAR is no longer confined to a retro-reflective surface. In fact, it’s no longer confined to augmented reality. An optional clip on adapter converts castAR into a “free” augmented reality or a full virtual reality system.
[Jeri] has also posted a video on her YouTube channel detailing the entire saga of castAR’s development (embedded after the jump). The video has a real “heart to heart” feel to it, and is definitely worth watching. The story starts with the early days (and late nights) [Rick] and [Jeri] spent at Valve. She goes through the split with Valve and how the two set up a lab in [Rick’s] living room. [Jeri] also outlines some of the technical aspects of the system. She explains how the optics have been reduced from several pounds of projectors to the mere ounces we see today.
Another surprise addition is the lower level tier rewards of the campaign. The castAR tracking system is offered. The campaign page says the tracking system can be mounted to anything from robots to other VR headsets. The possibilities for hacking are almost endless. We’re curious about setting up our own swarm of quadcopters similar to the UPENN Grasp Lab. The RFID tracking grid is also offered as a separate option. In the gaming system this will be used for tracking tabletop game pieces. Based upon the Kickstarter page, it sounds as if the grid will not only use RFID, but a camera based tracking system. We’re definitely curious what possibilities this will hold.
As of this writing, the castAR Kickstarter campaign is already well past the halfway mark on its way to a $400,000 USD goal.
If there was one sentence heard over and over at Maker Faire NY, it was “Did you see castAR yet?” The Technical Illusions team was at Maker Faire in full force. [Jeri Ellsworth], [Rick Johnson,] and team brought two demos: the tried and true Jenga simulator, and a newer overhead shooter based on the Unity 3D engine. We didn’t see any earth shattering changes from the previous demos of castAR, as [Jeri] has moved into optimization of the Hardware, and [Rick] toward even more immersive demos of the software. Optimization and preparing for market are considered the “hard yards” of any product design. This is the place where a huge amount of work goes in, but the changes are subtle to the layperson.
In addition to her development of castAR’s ASIC, [Jeri] has been hard at work on the optics. The “old” glasses used a solid plastic optical path. The newer glasses use a hollow path for the twin 720p projectors. This makes them even lighter than the previous generation. Weight on the castAR glasses can’t be overstated. They feel incredibly light. There was no perceptible pressure on the nose or ears when wearing them. Also missing was the motion sickness people often experience with VR. This is because castAR doesn’t replace the user’s vision field, it only augments the vision. Peripheral motion cues are still there, which makes for a much more comfortable experience.
