Google Glass Team: ‘Wearable Computing Will Be the Norm’


By Steven Levy

Even though I followed Google’s I/O Conference from across the country, the event made it obvious that a company created with a strict focus on search has become an omnivorous factory of tech products both hard and soft. Google now regards its developers conference as a launch pad for a shotgun spread of announcements, almost like a CES springing from a single company. (Whatever happened to “more wood behind fewer arrows”?)

But the Google product that threatened to steal the entire show probably won’t be sold to the public until 2014. This is the prosthetic eye-based display computer called Project Glass, which is coming out of the company’s experimental unit, Google[x]. Announced last April, it was dropped into the conference in dramatic fashion: An extravagant demo hosted by Google co-founder Sergey Brin involved skydivers, stunt cyclists, and a death-defying Google+ hangout. It quickly attained legendary status.

Even before people got to sample Glass, it was popping their eyes out.

Google wouldn’t provide a date or product details for Glass’ eventual appearance as a consumer product — and in fact made it clear that the team was still figuring out the key details of what that product would be. But Google made waves by announcing that it would take orders for a $1,500 “explorer’s version,” sold only to I/O attendees and shipped sometime early next year. Hungry to get their hands on what seemed to be groundbreaking new technology, developers lined up to put their money down.

Meanwhile, I just as hungrily bit at the opportunity to do a phone interview with two of the leaders of Glass. Google originally hired project head Babak Parviz from the University of Washington, where he was the McMorrow Innovation Associate Professor, specializing in the interface between biology and technology. (One relevant piece of work: a paper called “Augmented Reality in a Contact Lens.”)
The other Glass honcho, product manager Steve Lee, is a longtime Google product manager, specializing in location and mapping areas. Here is the edited conversation.

Wired: Where are you now with Glass as compared to what Google will eventually release?
Babak Parviz: Project Glass is something that Steve and I have worked on together for a bit more than two years now. It has gone through lots of prototypes and fortunately we’ve arrived at something that sort of works right now. It still is a prototype, but we can do more experimentation with it. We’re excited about this. This could be a radically new technology that really enables people to do things that otherwise they couldn’t do. There are two broad areas that we’re looking at. One is to enable people to communicate with images in new ways, and in a better way. The second is very rapid access to information.

Wired: Let’s talk about some of the product basics. For instance, I’m still not clear whether Glass is something that works with the phone in your pocket, or a stand-alone product.

Parviz: Right now it doesn’t have a cell radio, it has Wi-Fi and Bluetooth. If you’re outdoors or on the go, at least for the immediate future, if you would like to have data connection, you would need a phone.

Steve Lee: Eventually it’ll be a stand-alone product in its own right.

Wired: What are the other current basics?

Parviz: We have a pretty powerful processor and a lot of memory in the device. There’s quite a bit of storage on board, so you can store images and video on board, or you can just live stream it out. We have a see-through display, so it shows images and video if you like, and it’s all self-contained. It has a camera that can collect photographs or video. It has a touchpad so it can interact with the system, and it has gyroscope, accelerometers, and compasses for making the system aware in terms of location and direction. It has microphones for collecting sound, it has a small speaker for getting sound back to the person who’s wearing it, and it has Wi-Fi and Bluetooth. And GPS.

This is the configuration that most likely will ship to the developers, but it’s not 100 percent sure that this is the configuration that will we ship to the broader consumer market.
Wired: How much does it weigh?

Lee: It’s comparable to a pair of sunglasses. You can stack three of these up and balance a scale with a smart phone.



Wired: What was your thinking when you embarked on the project, and how did that thinking evolve?

Parviz: We did look at many, many different possibilities early on. One of the things that we looked at was very immersive AR [Augmented Reality] environments — how much that would allow people to do, how much could come between you and the physical world, and how much that can be distractive. Over time we really found that particular picture less and less compelling. As we used the device ourselves, what became more compelling to use was a type of technology that doesn’t come between you and the physical world. So you do what you normally do but when you want to access it, it’s immediately relevant — it can help you do something, it would help you connect to other people with images or video, or it would help you get a snippet of information very quickly. So we decided that having the technology out of the way is much, much more compelling than immersive AR, at least at this time.

'Tooth Tattoo' That Could Save Your Life



A 'tooth tattoo' made from silk strands and gold wires could be used to detect life-threatening illnesses, researchers have said.

The tiny wireless device sticks to dental enamel and transmits real-time updates on chemicals in the breath and saliva.

Engineers at Princeton University in America have used it to detect bacteria that causes surgical infections and stomach ulcers, and say it could also be used to recognise viruses.

The sensor is in the early stages of development, but the university’s researchers say it could one day be used to monitor human health with unprecedented accuracy.

During a demonstration, a volunteer breathed across a prototype sensor attached to a cow’s tooth.
It generated an instant response which was sent to a nearby monitor.

"The antenna coil is what transmits the signal," said Michael McAlpine, the team's principal investigator, “you don't need a battery."

Details of the invention were reported in the medical journal Nature Communications.
The researchers created the device by bundling the silk and gold with graphene - an extremely thin sheet of carbon.

Yet despite its complexity, it can be applied to a tooth's surface with water "like a child's transfer tattoo", the university said.

The sensor is currently too big to fit onto a human tooth, and needs further work to scale it down.
The team also plans to improve the sensor so that it can withstand eating and brushing over a long period of time.

"Ideally, you want something that would be there for a while. We have a way to go before we could master that," Mr McAlpine said.
