Seebright is currently inviting coders to apply for its developer competition, which will kick off in the fall with a low-cost developer version of the device priced about $100.
Meanwhile, Innovega was another exhibitor at the show with an even bolder idea: It is working on building a high-tech contact lens that would sit directly on top of the user's eye to "enhance" normal vision by super-imposing certain images on top of a user's regular field of vision. The applications of the technology are still being worked out, but Innovega is looking to partner with the U.S. Department of Defense for military uses, the company said.
Innovega's proposition is that devices like Google Glass, which align flat-panel displays in the frame with other optical components to focus the image, result in a small-scale viewing experience with bulky hardware. Therefore, the company is eliminating optics entirely from its device, "enabling higher performance and better style," Innovega says.
Augmented reality is a small field still in its early days. The basic idea behind most products with that label is to provide additional information or content to "augment" or improve people's daily experiences.
As opposed to virtual reality, which typically creates a new simulated world for the user, augmented reality works with what people can already see, the thinking goes.
But because the field's aims are so vague, there is some debate over whether it is its own market at all, or just a sub-domain of products build around mobile devices like smartphones and existing social media. Many features on the current form of Google Glass, for instance, are built around letting wearers quickly record and then share content with their contacts on Google+.
Using Augmented World Expo, now in its fourth year, as a barometer, interest in the field is at last growing. The more than 1,000 attendees at this year's event represent a 40 percent increase in attendance over last year, organizers said.
And there are plenty of other players looking to make waves in augmented reality that aren't using glasses-based products to do it. ChatPerf, also exhibiting at the show, is a Japanese company that makes an iPhone adaptor that emits perfume scents. Users of the adaptor can "receive" scents by text.
And then there's ARPool, or augmented reality pool, developed by students at the Robotics and Computer Vision Lab at Queen's University in Ontario, which uses custom computer algorithms and a projector-camera system to display ball trajectories onto the table as the player lines up a shot. Its developers were hoping to attract a commercial partner at the trade show to take the technology further.
Even Honda is getting involved in augmented reality. At the Honda Research Institute, researchers are working to make people better drivers by using computer-generated sensory information like GPS data and video to give drivers more information about their surroundings as they drive, possibly by displaying it directly on the windshield.
