NILoc (Neural Inertial Localization) enables precise indoor positioning through smartphone motion sensors alone, operating without additional hardware, privacy intrusions, or significant battery consumption — a major advance over GPS, which fails indoors.
The problem and solution
While GPS excels outdoors, indoor environments like airports and shopping centers leave users without navigation guidance. NILoc leverages existing phone sensors to fill this gap, offering accurate positioning in any building without infrastructure requirements from businesses.
Key advantages
The technology offers continuous privacy protection since it avoids camera or WiFi tracking, minimal battery impact compared to alternative positioning methods, and universal compatibility across building types without special installation.
Technical foundation
An AI model interprets motion patterns and builds location models specific to each building, processing movement data nearly instantaneously and outperforming traditional methods even without detailed architectural blueprints.
