Canada based Aegis Mobility has introduced a software to prevent mobile phone users from making telephone calls or text-messaging while driving.
The software DriveAssist uses advanced call management technology to detect when phones are moving at automobile speeds and then tells callers that the person they are trying to reach is driving. Callers are then invited to leave messages or call-back numbers. They can bypass the service and be connected to drivers by indicating calls are emergencies.
DriveAssist also comes with functionality for parents or employers to tell where the person they are trying to reach is located by using satellite navigation technology in devices or orienting based on cell signal towers being used. [yahoo]
