- Device Tracking Technology – North Carolina State University (NCSU) researchers developed Wi-Fi-assisted Inertial Odometry (WIO), approach using software to improve accuracy of tracking devices in indoor environments
- Problem – Inertial measurement units (IMUs) in devices still tend to be inaccurate, which are usually resolved by global positioning systems (GPS), however GPS signals are unreliable or nonexistent in indoor locations
- How It Works – Uses Wi-Fi as velocity sensor and works with typical IMUs in devices to better track movement of objects with radio waves
- Improved Accuracy – Devices using WIO calculated distance of object with margin of error between 5.9% to 10.5%. compared to 40% to 49% without it
- Applications – Include indoor navigational devices, fitness tracking and interactive gaming
- Future Plans – Currently working with Sony to further improve accuracy, with plans to incorporate software in commercial devices
