Users attach the device to their windscreen along with a single lens video camera that they install on the dashboard. CarVi then synchs with the driver’s smartphone, gathers data and provides real time audible and visual hazard warnings to improve their road safety. The co-pilot device provides the driver with an extra set of eyes, monitoring their position on the road, warning them if they get too close to other drivers and helping them change lanes safely. It learns their driving patterns and records them, enabling the driver to monitor problem areas and see improvements through video footage and data reports on the CarVi app.
