  ABSTRACT • Project Soliis a new technology that uses radar to enable new types of touch less interactions. • The movements of gestures from a human can be captured using a radar sensor, and by detection of theses gestures, some special task on a device can be done.

  INTRODUCTION • Project soliof Google ATAP(Advanced technology and project group) • Our hands and fingers are the best way we have to interact with smart devices. • One of the reasons is also the decreasing size of the screens.

  Project soli chip
• 5.
  • Can easilybe used in even the smallest wearable’s that fits with in a tiny chip. • It is capable of accurately detecting your hand movement in real-time. • Its like motion and other gesture-tracking controllers.
• 6.
  • The soliis small in size of a 5×5 mm. • It has a sensor which capture sub millimeters of motions of fingers in 3D space. • It capture motions of fingers at a phenomenal rate of 10,000 frames per second

  What a radaris …? • Radar is an object-detection system that uses radio waves to determine the range, angle, or velocity of objects. • It is used by Army and Defense agencies to track movements of enemy. • Sends radio waves towards the target and its receiver intercepts the motion.

  Types of Radars •Google developed two modulation architectures: a) Frequency Modulated Continuous Wave(FMCW) radar. b) Direct Sequence Spread Spectrum(DSSS) radar. • Both chips integrate the entire radar system into the package ,that enable gesture recognition
• 10.
  Features of Radar Insensitive to the light  Can transmit over plastic materials like polycarbonate  3D gesture recognition possible  Recognition of overlapping fingers

  Working • Soli sensortechnology works by emitting electromagnetic waves in a broad beam. • object with in the beam scatter this energy, reflecting some portion back towards the radar. • Properties of the reflected signal, such as energy, time delay and frequency shift capture rich information about the objects.
• 12.
  • Such asits characteristics and shape , size , material , distance and velocity.etc. • It then uses machines-learning to translate these movement to pre-programmed commands. • Doppler effect to detect speed • Virtual tools are used as a key to identify gestures.
• 13.
  What is machinelearning..? • Machine learning is subfield of computer science that evolved from the study of pattern recognition and computational learning theory in artificial intelligence
• 14.
  What is Dopplereffect? • It is named after the Austrian physicist Christian Doppler, who proposed it in 1842 in Prague. • The Doppler effect is the change in frequency of a wave (or other periodic event) for an observer moving relative to its source.
• 15.
  Virtual Tools • Theconcept of virtual tool is key to soli interactions • Virtual tools are gestures that familiar interactions with physical tools. • This make it easy to communicate, learn and remember soli interactions.

  Virtual tool Gestures Eg.(1) Imaginean invisible button between your thumb and index finger- you can press it by tapping your finger together
• 17.
  Using Google-Map byGestures Eg.(2) If you turn by rubbing thumb against index finger

  Controlling device functionalitiesusing Gestures
• 19.
  APPLICATIONS • In medicalfield.
• 20.
  • For playinggames
• 21.
  • Smartphones canbe controlled by using Gestures.
• 22.
  • In smartwatches.
• 23.
  • Gadgets
• 24.
  ADVANTAGES • Replace allkinds of buttons and switches and make the devices operable remotely • Most of the existing motion sensor technique uses camera based motion sensing • Allows to control Gadgets with gestures. • Allows free hand typing. • Good Accuracy over control . • Need not to carry gadgets while using them.
• 25.
  DISADVANTAGES • It hasa limited radar range. • Multiple gestures could not be possible at a time. • Highly Expensive. • Security Threat.
• 26.
  CONCLUSION • One ofthe big problems with wearable devices right now is inputs, there's no simple way to control these devices. • Therefore gestures will be used by individuals to carry out certain functions with electronic machines such as Smartphone's and desktops.
