Project Soli

Modern technology is simply an advancement of old technology. The impact of technology in modern life is unmeasurable. Modern technology increases human capabilities. With the advancement of technology, the whole world is becoming a gadget that we interact with, with software everywhere, which raises the question how can we react with the entire world?

Google has answered this question and gave us a technology so advanced, precise and small in size that it works even on the smallest of displays.
Forget touchscreens and buttons, Google’s Project Soli lets you control gadgets using hand gestures made in AIR.Called Project Soli, the system identifies subtle finger movements using radar built into tiny microchips to track our finger movements creating virtual dials, touchpads, and more.

Hand is the best method you have for interaction with devices, but not everything is a device. Project Soli wants to make your hands and fingers the only user interface you’ll ever need. Project Soli is really a radar that is small enough to fit into a wearable like a smartwatch. The small radar picks up on your movements in real-time, and uses movements you make to alter its signal.Moving the hand away from or side-to-side in relation to the radar changes the signal and amplitude. Making a fist or crossing fingers also changes the signal.

Rather than go hands-free, Project Soli makes your hands the UI — which may already  be cooler than voice control ever was. Project Soli is using radar to enable new types of touchless interactions — one where the human hand becomes a natural, intuitive interface for our devices. The Soli sensor can track sub-millimeter motions at high speed and accuracy. It fits onto a chip, can be produced at scale, and can be used inside even small wearable devices.

So, From Where, the idea came from?
The idea behind Soli is similar to Leap Motion and other gesture-based controllers: A sensor tracks the movements of your hands, which control the input into a device.But unlike other motion controllers, which depend on cameras, Soli is equipped with radar, which helps it track sub-millimeter motions at high speed and accuracy,

SO WHAT ACTUALLY IS PROJECT SOLI?
Project Soli was revealed during Google I/O 2015 on May 29, 2015.Project Soli is an input technology developed by Google ATAP. It utilizes radar to detect the movements and gestures of your hands and fingers. Shaped as a chip the size of a quarter, Soli can be embedded in most wearables and electronic devices. The initial applications for the radar system are smartphones and smartwatches.

How Does It Work?
Soli is a 60GHz RF transmitter that uses board beam radar to measure everything from spectrogram to doppler image to IQ. Using these information, The tiny circuit board is able to determine the hand size, motion and velocity. It then uses machine-learning to translate these movements to pre-programmed commands.

Features

1. Translates hand gestures and finger movements into commands for your smart devices.
2. The sensor can track sub-millimeter motions at high speed and accuracy.
3. Small gestures such as turning of a nub or sliding of a page work fine.
4. Works through materials such as fabric

At the end, it can be said that this type of technology can help us to interact with the real world more conveniently and easily.We can now say that an era is coming where human and technology in collaboration with each other can possibly do those things which are earlier very difficult to achieve for the humans alone.
