Texting While Walking Draws Safety Concerns—And An App (WGBH)

By releasing an app that prevents pedestrians from getting hit by traffic, Dartmouth’s Smartphone Sensing Group has joined a growing debate about “distracted walking.”

The group, led by Computer Science Professor Andrew Campbell, has developed a free application for Android phones called WalkSafe. It uses the Android’s camera to detect oncoming cars and alert the phone’s user.

“Smartphones are getting smarter,” Campbell said. “They have a number of in-built sensors. … These sensors allow the phone, for the first time, to mimic human perception.”

Dartmouth Smartphone App Targets Driver Safety

Joseph Blumberg

“CarSafe” is a driver safety app that detects dangerous driving behavior using dual-cameras on smartphones. This is the latest smartphone app to come out of Dartmouth and is featured in the September 25 NewScientist. The Android app was developed by Professors Andrew Campbell and Lorenzo Torresani in the Department of Computer Science, and Dartmouth’s Smartphone Sensing Group.

The new app offers safety features typically found only in top-of-the-line cars. Simply mount the phone on the windshield with one camera facing the driver and the other facing the road. It operates with navigation apps and monitors the driver and the road while calling attention to dangerous conditions.

The video below, produced by Giuseppe Cardone of the University of Bologna, provides more details on the app and its operation. Cardone was a visiting PhD student working with Campbell and has since returned to Bologna.
