NVIDIA Research's near-eye light field display prototype eyes-on (video)

Source: http://www.engadget.com/2013/07/24/nvidia-research-near-eye-light-field-display-prototype/

A quick stroll through the Emerging Technologies section of SIGGRAPH usually reveals a collection of university projects and the latest Disney Research endeavor. However, we don't usually see the likes of NVIDIA amongst the fold there. This time around, though, the component maker is showing off an undertaking from its Research sector: near-eye light field displays. To show the project off, a pair of OLED mircodisplays were installed on a glasses-like frame with a box for the electronics stashed up top. Those Sony ECX332A panels measure 15.36 x 8.64mm wield a resolution of 1,280 x 720 through 24-hit color pixels (which equates to a smidge over 83 pixels per millimeter). The diminutive displays open up the door for thinner and lighter head-mounted units that can sort "accurate accommodation, convergence and binocular-disparity cues."

The light field that's constructed directly over the pupil allows the viewer to focus at multiple depths and create a field of view of about 70 degrees. Both of those aspects were quite apparent to our peepers upon getting locked in for a quick demo. Despite being situated so close to the eye, the unit still provides some sharp images that we witnessed first hand. Of course, the close proximity causes some pixel loss at the hands of a decreased spacial resolution. One pretty neat aspect to this whole system is that software tweaks can be made to account for someone's glasses or contacts prescription -- software that's powered by NVIDIA GPUs and OpenGL, of course. Without having to modify the hardware, changes to the microdisplays are sorted sans the need to switch to another set or make physical adjustments. For a bit more explanation of the unit, check out the video that resides just past the break and full findings that were presented here in Anaheim at the coverage link that follows.

Lenovo's first Snapdragon 800 phone leaked as the K6 or X910

Despite the fact that Lenovo hasn't yet embraced the Snapdragon 600 SoC, it looks like the Chinese company's finally giving Qualcomm a proper chance with the latter's more powerful Snapdragon 800. Starting yesterday, several cheeky images of an unannounced dual-SIM Android phone -- codenamed K6 or X910 -- popped up in Lenovo's official Chinese forum. The photo after the break shows AnTuTu indicating the presence of the relatively new MSM8974 chip (with Adreno 330 GPU) plus a 1,920 x 1,080 display (which looks like a 5-inch panel to us); so unless the app made a mistake, what we have here could be Lenovo's upcoming flagship device.

While not much else has been said about the phone, one of the leaksters described it as thin and light, and that it felt good in hand. But to be honest, we're not too thrilled with the design ID here, especially with that K860-inspired back. What's interesting, though, is that according to a source of ours, the "X" in X910 may be a wildcard that depends on the kind of deal Lenovo made with Qualcomm. At this point, we've been told to assume it'll eventually become the K910, which would, sadly, make this phone an uglier successor to the Intel-powered K900. Either way, chances are we won't be seeing many of these outside China, anyway.

The new Nexus 7 vs. last year's model: what's changed?

Source: http://www.engadget.com/2013/07/24/nexus-7-whats-changed/

Google's second-generation Nexus 7 hasn't been the company's best kept secret -- we've seen leak after leak, after leak and, well, you get the point. Still, now that the revamped 7-inch slate is officially out the bag, we can finally leave speculation behind and attach some formal specifications to the thing. As expected, the new Nexus 7 brings a number of internal upgrades to the table, while its outer shell has seen a few minor aesthetic changes. All signs point toward it being a worthy successor to Mountain View's popular tablet, but how big of an upgrade are we talking about, exactly? Those answers await after the jump, where we break down the specs and spell out what's different between the old and new Nexus 7.

Google introduces Chromecast, a $35 HDMI streaming solution for televisions (video)

Source: http://www.engadget.com/2013/07/24/google-chromekey/

Google's Chromecast is Mountain View's next foray into the television market. In brief, it's a $35 HDMI dongle that mirrors content being played nearby on a tablet, smartphone or computer. Hrm, that sounds familiar. The 2-inch device runs "a simplified version of Chrome OS" and requires separate USB power; connect it to your local WiFi network and similarly connected devices work with Chromecast. It can be ordered right now on Google Play and will apparently ship in one to two days. Of note, the device seems US-only for now, as our UK colleagues are showing a "not available in your country" prompt. Early buyers get three months of free Netflix with the purchase. Additionally, it's also heading to retail (read: Best Buy) on July 28th. Google ended its presentation with a quick word that Chromecast functionality will eventually come embedded in various other devices, and that it's working on getting other countries access "as quickly as possible." No specs were given during the presentation, but its Google Play page lists the device as HDMI-CEC compatible, and it uses 2.4GHz 801.11 b/g/n WiFi. Given the separate USB power required, the $35 nets you a Chromecast device, an HDMI extended, a USB power cable and a separate power adapter.

Apps that work with the device include a "Cast" button that allows users to push video to their televisions and control various aspects remotely (volume, play, pause, etc.). "Once Chromecast is plugged in, you just go to YouTube on your smartphone," Google reps said. "You'll see the cast button in your UI and you press it -- Chromecast will pull the info you requested from the cloud and play it on your TV." Meanwhile, an on-stage demonstration showed YouTube video being pushed "via the cloud," thus enabling other apps to be used while a video is being viewed on a television screen. Netflix was up next, and it has similar remote control functionality. Google Play movies and television (expectedly) also work with Chromecast, and Google delightedly demonstrated it with Vin Diesel vehicle Fast Five. Finally, Google demoed full Google Chrome projected on a TV and controlled remotely with a "standard $500 Windows 8 laptop." The feature is "still in early days," but a promise has already been made: that users will be able to easily project content to televisions via their web browser.

Update: We've added Chromecast's first commercial (which demonstrates much of the device's functionality) just after the break, and a source link with Google's formal announcement.
