Researchers reduce VR sickness by letting your eyes focus
Virtual reality has unlimited potential, but it could make you sick. Stanford researchers are trying to solve that problem by tapping another new tech, light-field cameras. You see, VR devices can cause fatigue and nausea because of the "flat plane" 3D images they produce. Since those images don't contain any depth information, your eyes can't focus on near and far objects like you would in real life. Our brains want physical actions (like focusing) to jibe with what we see, so any disconnect can make us sick. And if companies can't solve this "VR sickness," the tech may go the way of 3D TVs.
'Light Field' 3D maps take VR broadcasting to the next level
Ever since I experienced a live 3D virtual reality broadcast for the first time, I've been giving demos of the technology to anyone who will sit still long enough for me to put a Gear VR on their head. Across the board, the reactions have included at least two things: "This is amazing," and, "Can you move around like you're really there?" Now, NextVR says the answer to that question is yes, since it's adding "Light Field" (aka plenoptic) capture technology to existing rigs (like this 6K unit shown above) that will let viewers look around the scene with full six degrees of freedom. This is similar to the tech Lytro uses for its cameras that lets you change focus after a picture is taken -- and just got a $50 million investment to implement on VR. According to NextVR, its patented approach creates a 3D geometric model of the scene (shown after the break) ready for headsets like the Oculus Rift, Sony's Project Morpheus or even augmented reality units like Microsoft's HoloLens or Magic Leap's... whatever it is.
Lytro to get Perspective Shift and Living Filters for more focus-shifting fun (video)
Lytro has just announced a software update that expands upon the multidimensional elements of the little light-field point-and-shoot. The Lytro Desktop software will get two new features, dubbed Perspective Shift and Living Filters, both of which expand upon the device's focus-shifting capabilities. Perspective Shift lets you change the photo's center of perspective, while Living Filters are interactive image effects that range from cool to kooky. We had a chance to get an early look at these features, so join us after the break for our impressions and video of them in action.
Lytro camera getting parallax effect and 3D display support, lands in Hong Kong (video)
Lytro isn't done extending the usefulness of its light field camera just because we have manual controls. Another update due by the end of the year will take advantage of that focus-independent sensor to allow a parallax-based 3D effect in photos: invoke a 'full' focus in reviewing shots and you can start poking around the scene in a limited way without having ever touched a dual-sensor camera. Appropriately, we're also getting support for examining photos on 3D monitors and TVs that emphasize the added depth. The promised features come hand-in-hand with Lytro's immediate availability in Hong Kong, where 8GB blue and gray cameras are selling for $3,888 HKD ($502 US) and the 16GB red model goes for $4,688 HKD ($605). Check out our Chinese crew's eyes-on look at the parallax effect in a video after the break.
Lytro camera gets manual controls, new colors and accessories for exacting light-field fans
A frequent gripe of Lytro camera owners has been the hands-off nature of the photography, with that signature infinite focus about the only real fine-tuning that's on tap. As of a fresh firmware upgrade, the light-field camera is much friendlier to demanding shooters. The unconventional point-and-shoot now lets owners manually adjust the ISO sensitivity (80 to 3,200) and shutter speed (1/250th of a second to 8 seconds) as well as lock the exposure or invoke a neutral density filter. Regardless of their precision demands, anyone who was already sold on the concept still gets a few perks with today's refresh: the 8GB model now comes in Seaglass green and a Target-exclusive Moxie Pink, and there's both a $30 sleeve as well as a $60, accessory-friendly case for those who've fully committed to the Lytro lifestyle. Neither upgrade will bring higher resolutions or video, but they'll go a long way towards accommodating those who were at least on the fence. Check out an interactive sample of the shutter speed control's benefits after the break.
How would you change the Lytro?
Few products make everyone here at Engadget quite as giddy with excitement as Lytro's light-field camera. Given how regularly we need to photograph things, we were desperate to know if this was going to revolutionize the way we snapped pictures. It had more than a few things going for it, innovative product design, great engineering, it was fast, responsive and had a great UI. However, the pictures themselves were of a low resolution, and the depth-of-field trickery only works with extreme close-up-and-background shots where you can mess around with your bokkeh. As nice as it is in theory (and practice, on a well-lit day), it's certainly not going to replace your DSLR any time soon -- but given that the company's presumably working on version 2.0 of the device, what would you suggest they tweak?
Lytro's light field camera captures 'unprecedented' images, lets you choose focus later
A Silicon Valley start-up called Lytro claims it's working on a consumer camera that uses light field technology to radically change the way we take, edit and experience photographs. Whereas a normal digital camera captures a snapshot of light hitting a sensor, a light field camera first separates rays of light in order to individually record their color, intensity and direction. This extra information opens up a world of possibilities, including the ability to focus on any depth of field within a taken photo, observe a 3D-type effect even without specs, and boost images taken in extremely low light. Although light field cameras have been around for some time, they haven't been commercially viable. Now though, Lytro has secured backing worth $50million to bring a "competitively priced" camera to market "later this year" -- we'll see if they can beat similar plenoptic technology from Adobe to market. Can't wait that long? Check out the interactive photo (click on Elvis to re-focus) after the break, plus a video that also shows off the 3D effect. Both are the definition of mind-blowing.
