Project soli
- 1. PROJECT SOLI BHAVIN B S5 MCA-B KVM CE & IT
- 2. ABSTRACT • Project Soli is 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.
- 3. INTRODUCTION • Project soli of 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.
- 5. • Can easily be 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 soli is 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
- 7. What a radar is …? • 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.
- 8. Simulation of wave recognition
- 9. 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
- 11. Working • Soli sensor technology 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 as its 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 machine learning..? • 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 Doppler effect? • 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 • The concept 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.
- 16. Virtual tool Gestures Eg.(1) Imagine an invisible button between your thumb and index finger- you can press it by tapping your finger together
- 17. Using Google-Map by Gestures Eg.(2) If you turn by rubbing thumb against index finger
- 18. Controlling device functionalities using Gestures
- 19. APPLICATIONS • In medical field.
- 20. • For playing games
- 21. • Smartphones can be controlled by using Gestures.
- 22. • In smart watches.
- 23. • Gadgets
- 24. ADVANTAGES • Replace all kinds 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 has a limited radar range. • Multiple gestures could not be possible at a time. • Highly Expensive. • Security Threat.
- 26. CONCLUSION • One of the 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.
