Google Glass to gain local apps, but not cellular connection

Google Glass will eventually gain the ability to run local apps from the device itself, Glass creator Babak Parviz told a conference audience on Monday.

Parviz, speaking at the Hot Chips conference at Stanford University, charted the evolution of Glass as packing more computer power into progressively small former factors, from mainframes to PCs to smartphones, and on to wearables.

Google has a “few thousand” of Glass devices available in the wild, through its Explorer program, Parviz said. The glasses use either a Bluetooth or Wi-Fi connection to pull in data, which is projected onto the surface of the clear plastic of the Glass lens. So far, Google Glass wearers can record video, take pictures, launch Hangouts, navigate, and search for information. However, Google continues to add new features to Glass via periodic updates; some recent additions include the ability to view YouTube videos, pausing playback while orienting a “cursor” over the appropriate button.

Third-party apps for Glass are also beginning to take shape, with The New York Times, among others, rolling out services for what Google hopes is a new platform, Parviz said. “We still have a lot of data centers, a lot of computers, a lot of smartphones, and a lot of notebooks,” he said. “So even though these new platforms appear, the previous platforms don’t totally disappear.”

For now, however, those services run in the cloud. In fact, everything runs in the cloud, Parviz said. “In the next generation of the platform, we may allow people to run things from here,” he said, gesturing to the Glass itself.

The problem, of course, is that adding anything to the Glass device—whether it be more storage, a faster processor, or other capabilities, may have implications on the device itself. The majority of power consumed by smartphones is due to both the display and the cellular radio; while Parviz did not explicitly connect the two, Glass lacks a cellular radio, and “there is no plan to put a cellular radio immediately in Glass right now,” Parviz said. The assumption, of course, is that doing so would pare down the Glass battery life.

A version of Glass for prescription lenses is also on the way, as Google executives have said before, “In the next few months we’ll integrate it into glasses,” Parviz said.

But don’t expect it to go much farther than that. Parviz said that his work at the University of Washington involved trying to project images onto the curved surface of a contact lens—a project that proved incredibly difficult for even a single pixel.

Numerous audience members asked Parviz about the societal elements of Glass, from its impact on security to just wondering whether they could avoid being recorded by Glass. Parviz slid by the question, noting that in the late 1880s the rise of portable cameras prompted concerns that anyone would take a picture of another person in a public place, something that is legal under U.S. law. “The user will have to have some judgement,” he said.

Google blocks Chromecast app that streams local media files

You can stream a lot of content to a Chromecast dongle, but one thing you can’t do is stream your personal files from an Android device—and according to one developer, Google's actively working to keep it that way.

A beta version of an Android application called AllCast has lost the ability to stream content to Chromecast from Android apps such as the photo gallery, Dropbox, and Google Drive.

“Google's latest Chromecast update intentionally breaks AllCast,” said Android developer Koushik Dutta in a recent Google+ post. The company removed a developer option called “video_playback,” which as its name suggests, allowed any application to support video playback.

Dutta believes this is a sign that Google will not be friendly toward third-party developers of Chromecast apps compared to the relative openness Android developers enjoy on Google Play. “The Chromecast will probably not be indie developer friendly,” Dutta said in his post. “The Google TV team will likely only whitelist media companies.”

“We’re excited to bring more content to Chromecast and would like to support all types of apps, including those for local content,” Google said in a statement when we reached out to them for comment. “It’s still early days for the Google Cast SDK, which we just released in developer preview for early development and testing only. We expect that the SDK will continue to change before we launch out of developer preview, and want to provide a great experience for users and developers before making the SDK and additional apps more broadly available.”

Indeed, in its Chromecast developer documentation, Google says that all functionality is subject to change.

Regardless, Google certainly hasn’t made it easy for Chromecast users to stream their own video files to their TV—an obvious feature deficit. Competitors such as Apple TV already allow you to stream content from your PC or iOS device; however, Apple restricts video formats to h.264 and a specific type of MP4.

Many critics suspect that Google left out the ability to stream personal videos to make its new Web-meets-TV platform more attractive to movie and television studios concerned about piracy. Instead of buying approved content from Google Play or Amazon, the argument goes, users could just download a pirated copy of Sunday night’s Breaking Bad episode and send that to Chromecast.

If the speculation is accurate, it’s rather unfair to limit obvious functionality on Chromecast just to make sure Hollywood doesn’t get spooked, especially since Apple TV could broadcast pirated video to your TV right now. Plus, anyone with the technical know-how to download a pirated video (especially via torrents) likely figured out how to put that content on their TV long before Chromecast showed up.

If you’re absolutely dying to stream personal videos to your Chromecast, one workaround for now is to try casting from your PC. Our recent primer on seven Chromecast tips and tricks shows you how to easily access a PC’s file system from an open Chrome tab.

Facebook eyes making local connections with mesh networks

Facebook has designed a system that would allow individuals and advertisers to make direct connections to those physically nearby that share similar interests or are open to receiving certain advertisements.

The company’s work was outlined in a U.S. patent filing for a “wireless social networking” system that was published this week and represents a further step towards advertising and communication that is locally targeted.

Under the envisaged system, a wireless device would establish a connection with other wireless devices nearby. The communication wouldn’t run via the Internet but would be based on a direct link between the devices. Each device might be linked to one or many other devices, depending on the density of people in a certain area, and each would be open to sending, receiving and relaying messages as part of the mesh network.

Because the network is based on direct connections, the approximate location of users can be determined. For example, if a device has a 100-meter-range then all other devices it is in direct contact with could be determined to be within 100 meters. If those devices acted as relays, then a second level of devices could be determined to be within 200 meters and so on. The number of relays, or “hops,” lies at the heart of the envisaged system.

The system outlined in the patent application envisages users setting preferences for receiving or communicating with others based on interest and proximity. Facebook calls the combination of these two factors an “interest metric.”

“In general, the wireless device may enable messaging communications with wireless neighbors that have higher interest metrics and avoid enabling messaging communications with wireless neighbors with lower interest metrics,” the application said.

Users would categorize themselves as individuals, businesses and advertisers with further sub categorize for finer distinctions.

“In one example, the neighbor type ‘restaurant’ may be sub-divided into multiple sub-groups, such as ‘Italian,’ ‘Thai,’ ‘French,’ and others. In another example, the neighbor characteristics depend on the content advertised by the neighbor, such as the specific value of store discounts. In addition, the neighbor characteristics may indicate a neighbor’s interests or social activities, such as interests in poker, science fiction, or kung-fu movies,” the application said.

“The user may assign different interest metrics to different neighbor characteristics. Hence, the user may set the interest metrics to the highest value for the individuals interested in poker, the medium value for the stores advertising free pizza, and the smallest value for stores advertising discounts on winter clothes that are less than 20 percent off. As a result, the wireless device may prevent messaging communications with the stores advertising discounts on winter clothes, because these stores’ have interest metrics that are too low for the user.”

Businesses are continually trying to refine their advertising so it only reaches consumers that might become customers. That’s especially true of local businesses, which often have limited advertising budgets.

That’s where the mesh networking trumps an Internet connection, according to the patent application.

“Finally, enabling communications based at least in part on network proximity may also assist businesses in identifying potential customers. In one example, the owner of a pizzeria may only want to advertise a ‘7:30 special’ to the customers who are close-by to the pizzeria to avoid advertising to customers who are too far away to take advantage of the ‘7:30 special.’ In another example, a department store with a large number of diverse products may tailor its promotional advertisements to the customers shopping within specific store sections. Hence, customers shopping in a ‘Women’s Shoes’ section may receive advertisements that are different from advertisements received by customers shopping in a ‘Men’s Suits’ section.”

The system wouldn’t be totally focused on advertising—and that might be key if users were ever to sign on should such a system launch. The interest list would also enable users to find others nearby that shared similar interests and hobbies or act as a filter for discovering existing friends that are in the area.

Details are included in U.S. patent application 20130208714 that was published on Thursday. It was filed with the U.S. Patent and Trademark Office on March 14 this year.

Patent applications provide insight into the types of projects that companies are working on. They are typically filed early on in the development process and the appearance of a patent application doesn’t necessarily mean a future commercial product.
