Professor Brett Story and a group of Garland High School students are putting smartphone data to work to identify cracks and foundation problems in bridges that could lead to serious damage over time.

By gathering information collected by smartphones in passing cars, Story and the students aim to check the bridge’s structural health.
The information Story needs is collected by the smartphone’s accelerometer. An accelerometer is generally used to measure how quickly something is moving.
