Abstract

Disclosed is a system that uses two sensors, one for sensing motion and one for detecting eye movement, which are already built into many cellular phones, to determine when a driver is talking, texting, or using applications on a cellular phone while driving.

System to prevent phone usage while driving

For a driver to use a mobile phone while driving to send text messages, play games, use applications, or place a phone call is extremely dangerous and illegal in many jurisdictions. Existing systems can monitor and prevent texting and driving, but these require specialized equipment and do not prevent general phone usage.

The novel contribution is a system that uses two sensors that are already built into many phones to detect phone usage while driving: a Global Positioning System (GPS) or other sensor that detects the phone is in motion, and a front facing camera to track eye movement, which indicates that a driver is using the phone. Using eye movement patterns to determine whether a cell phone user is a driver or a non-driver is not trivial or obvious.

The first part of the system attempts to detect whether a phone is in a moving vehicle . To detect if a car is in a moving vehicle, the phone's GPS or other sensors can be used to determine if the phone is in motion , and a (configurable) range of speed (e.g., 10km/h to 200km/h) can be used to determine if it is in a moving car. Another way of determining that a cell phone is in a moving vehicle is with triangulation via cell phone towers.

Once the system determines that the phone is in a moving vehicle, the second part of the system tracks a user's eye movement via the front-facing camera. A driver has a unique pattern when using a cell phone than a passenger does. S...
