The researchers found that using WIO improved a device's speed and distance calculations dramatically. For example, devices using WIO calculated distance with a margin of error ranging from 5.9% to 10.5%. Without WIO, the devices calculated distance with a margin of error from 40% to 49%.
"We envision WIO as having applications in everything from indoor navigational tools to fitness tracking to interactive gaming," Venkatnarayan says.
"We are currently working with Sony to further improve WIO's accuracy, with an eye toward incorporating the software into off-the-shelf technologies," says Shahzad.

The paper, “Enhancing Indoor Inertial Odometry with WiFi,” by Raghav H. Venkatnarayan and Muhammad Shahzad, North Carolina State University will be presented at UbiComp 2019, being held from September 11-13 in London, U.K. The work was done with support from the National Science Foundation, under grant 1565609.
