Over the past few decades, the research focus of wireless communication
technology has been shrinking in terms of coverage area. Wireless
positioning/location services present a perfect analogy to wireless
communication services. It started with the use of Global Positioning
System (GPS), and is trending towards Local/Body Area Positioning System
This research talk focuses on the development of a low-latency positioning
system for Personal Area Tracking (PAT), which uses AC magnetic field to
locate the position and orientation of its sensor in real-time with sub-mm
accuracy. The system consists of a low-power antenna (transmitter) and one
or more sensors (receivers). The sensor module consists of a tri-axial RF
(radio frequency) field sensor, an orientation sensor, a micro-controller
and a communication unit. The system achieves a precision of 1mm in
position with 0.1 degree in at 1m from the antenna. The transmitter and
the receiver consume 1W and 0.4W of power, respectively, providing 400
updates/sec with only 5ms of latency. The system is robust to multi-path,
low-power, low-cost and provides complete location privacy to its users.
The system is developed to provide an intuitive and easy-to-use interface
for VR and AR applications. This technology can also be applied in the
field of 2D-gaming, media entertainment, security, robotics, bio-medical,
motion-capture and home-automation. This technology was awarded 3rd place
in ‘Best Live Demo’ category at IEEE Sensors conference in 2016.

Mohit Singh is a Ph.D. candidate at Purdue University working with Prof. Byunghoo Jung on 3D positioning technology since 2012. He has a year of product design experience as an Analog Design Engineer at Intel India Pvt. Ltd, Bangalore. He received his Master's in Microelectronics in 2011 from IIT Bombay working with Prof. Shalabh Gupta, during which he worked on the development of efficient methods for testing communication links using Pseudo Random Sequence Generators (PRSGs), and DAC design. In 2016, Singh cofounded AccuPS Inc. (www.accups.com) for commercializing the 3D-positioning technology. Singh has participated as an Entrepreneur Lead (EL) in NSF's i-corps program for start-ups and has also been through Applied Management Principles (AMP) training at the Krannert School of Management. Team lead by Singh has won prizes in Burton D Morgan Business Competition and Schurz Innovation Challenge for their positioning technology.
