My name is Ivan Poupyrev  and I work for advanced technologies and projects  group at Google. The hand is the 1.__________________ input device. It's extremely 2.________________, it's extremely fast and it's very natural for us to use it right. Capturing the possibilities of the human hand was one of my 3.__________________. How could we take this incredible capability, the 4._______________ of human actions and finesse of, of using our hand but apply it to the virtual world? We use radio frequency spectrum which is radars to track human hand. The 5._______________ have been used for many different things, to track cars big objects satellites and planes. We're using them to track micro motions, twitches of the human hand and then use that to interact with wearables and internet things and other computing devices.

 

Our team is focused on taking radar hardware and turning it into a 6.___________ sensor. Radar is a technology which 7.________ a radio wave towards a target and then the receiver of the radar intercepts the reflected energy from that target. The reason why we're able to 8._________ so much from this one radar signal is because of the full gesture recognition pipeline that we've built. The various stages of this pipeline are designed to extract specific gesture information from this one radar signal that we receive at a high frame rate.

From these strange foreign range doppler signals we're actually interpreting human intent.

 

Radar has some unique properties when compared to cameras for example. It has a very high positional acuracy, which means that you can sense the tiniest motions. We arrived at this idea of virtual tools because we recognized that there are certain 9._______________ of controls like a volume knob, or a physical slider, a volume slider. Imagine a button between your thumb and index finger  and the button's not there but pressing this is a very clear action and there's an actual haptic feedback that occurs as you perform that action. The hand can both embody a virtual tool and it can also be, you know acting on that virtual tool at the same time, so if we can recognize that action we have an interesting direction for interacting with technology.

 

So when we started this project you know, me and my team, we looked at the project idea and we thought " are we gonna make it or not? Eh we don't know." But we have to do it because unless you do it, you don't know. What I think I'm most proud about our project is we have pushed the processing power of the electronics itself further out to do the sensing part for us.

 

The radar has properties which no other technology has. It can work through materials, you can 10._____________ it into objects, it allows us to track really precise motions and what is most exciting about it, is that you can 11._____________ the entire radar and put it in a tiny chip. That's what makes this approach so promising. It's extremely reliable, there's nothing to break, there's no moving parts, there's no lenses, there's nothing just a piece of sand on your board.

 

Now we are at a point where we have the hardware where we can 12.___________ these 13.___________________ and we can put them to work. We can explore how well they work and how well they might work in products. It blow's your mind usually when you see things people do and that I'm really looking forward to. I'm really looking forward to releasing this to the development community and I really want them to be excited and 14._________________ to do something cool with it, right?
