This blog is all about science and technology (with occasional math thrown in for fun). The goal of this blog is to try and pass on the sense of excitement and wonder I feel when I read about these topics. I hope you enjoy the posts.

Virtual/Augmented Reality News

Posted May 28, 2015 9:45 AM by Bayes

The Elusive Virtual Reality

For years now we have been hearing about the Oculus Rift, a virtual reality head-mounted display. Finally it appears it will be coming to market with a consumer version priced around $1500 becoming available in the first quarter of 2016. The reviews have been good, though the devices look like something millennials' kids will mock 25 years from now.

Meanwhile Microsoft is getting into the game with an augmented reality device, the Hololens.

Here is the the Microsoft Presentation

As you can see, it is a different approach as is indicated by "augmented reality" as opposed to "virtual reality". Here is an interesting article on the Hololens:

Microsoft's HoloLens Will Put Realistic 3-D People in Your Living Room

Demonstrations of augmented-reality displays typically involve tricking you into seeing animated content such as monsters and robots that aren't really there. Microsoft wants its forthcoming HoloLens headset to mess with reality more believably. It has developed a way to make you see photorealistic 3-D people that fit in with the real world. With this technology, you could watch an acrobat tumble across your front room or witness your niece take some of her first steps. You could walk around the imaginary people just as if they were real, your viewpoint changing seamlessly as if they were actually there. A sense of touch is just about the only thing missing.

That experience is possible because Microsoft has built a kind of holographic TV studio at its headquarters in Redmond, Washington. Roughly 100 cameras capture a performance from many different angles. Software uses the different viewpoints to create a highly accurate 3-D model of the person performing, resulting in a photo-real appearance. The more traditional approach of using computer animation can't compare, according to Steve Sullivan, who works on the project at Microsoft. He demonstrated what Microsoft calls "video holograms" at the LDV Vision Summit, an event about image-processing technology, in New York on Tuesday. More details of the technology will be released this summer. "There's something magical about it being real people and motion," he said. "If you have a HoloLens, you really feel these performances are in your world."

I find the idea of these devices fascinating, but I have certain practical questions I have yet to see answers to. As in the picture above, all the different devices I've seen are fixed firmly to the head.

How are those of us who wear glasses accommodated?

I wonder about people tripping over furniture, family and pets that are also in the real room when you try to peer around something in the virtual room. The earlier versions of 3D- Virtual Reality displays I remember seeing always had either a spotter for the one in the VR or some other way to limit the motions of the one blinded to reality.

What I would like to try is tele-presence (if that's the term), where the attitude of the goggles drives pan/tilt controls of a remote set of cameras.

What if you had the cameras mounted on top of a car or aircraft so that the driver or pilot could have a totally unobstructed view of the surroundings (just thinking).
