Feb. 28 (Bloomberg) –- MIT Mechanical Engineering Professor John Leonard discusses the technology Google is working on to take a 3D perception of our physical environment and bringing it to your phone. He speaks to Cory Johnson on Bloomberg Television’s “Bloomberg West.” (Source: Bloomberg)

That is so very different.

Great to talk to you -- what google is doing is taking technology that has been around a while, localization and mapping developed primarily for robots and sticking it on a smart phone.

What's exciting is ringing 3-d perception of our physical environment onto a phone.

Opportunities like indoor gps and the ability to build 3-d maps in real time and localized people or devices and then add on information about the world like the location of objects and behavior of people, it's a really exciting space and will bring search into the physical everyday environment.

Let's break this into two things -- one is the technology and the other is the data.

Let's start with technology.

What is the technological innovation that is very different that we are seeing with this?

A key difference is bringing it all together, the level of integration.

Some of the things they have been doing with laptops or more computing but in terms of packing it in such a small device, that is the key innovation.

It is challenging because as you move a device through the world, it accrues uncertainty.

If you had a map, you could localize yourself but we don't have a map in our house.

The key trick of this simultaneous localization of mapping is to localize the mapping.

It's called slam?

Simultaneous localization and mapping.

I have dedicated my academic career to this for over 20 years.

The google self driving car project inventor was one of the key proponents of slam.

A lot of this academic work is getting into real physical devices that can be deployed in people's houses.

I started slam magazine but it was about basketball.

What about the data?

There seems to be a common thread through all these projects at google.

The opportunity to capture so much data about the physical world and register it and remove the uncertainties and stitch it all together -- it opens pretty amazing possibilities.

Imagine going through a shopping mall or through a big warehouse store or a big office environment and being able to determine the physical locations of objects and register that together.

You could have the equivalent of what i call robot googleor google for the physical world to locate object and the possibility to combine them with the cloud, things like where are my car keys -- it could be like search but for the physical world.

John leonard, thank you very much.

It is time for the "
