For years, Google (NASDAQ:GOOGL) has walked the fine line between innovative and invasive. "Project Tango" continues the tradition in a way that's good for investors, Fool contributor Tim Beyers says in the following video.

What is "Project Tango"? Generally speaking, it's a phone. But it's also a motion-sensing device capable of 3-D-mapping a space in extraordinary detail. The idea, Tim says, is to give developers a platform for new apps that provide everything from indoor navigation to immersive gaming.

We've seen Google experiment with this sort of technology before. Remember "Ingress," the Google-developed game that used your smartphone to view enhanced images of the world around you? Think of it as the 1.0 version of the sorts of immersive gaming experiences Google wants to enable via "Project Tango."

But can it work? Sure, Tim says. Google already has experience blending the digital into our walkabout lives via Google Glass. "Project Tango" technology takes the idea a step further. Meanwhile, the virtual reality simulation Oculus Rift was a runaway hit at CES while researcher MarketsandMarkets projects 15.18% annualized growth in the market for VR and immersive games between now and 2018.

Now it's your turn to weigh in. What's your view of "Project Tango"? Please watch the video to get Tim's full take, and then leave a comment to let us know where you stand, and whether you would buy, sell, or short Google stock at current prices.
