CarVi is a handy stick-on gadget that lets you enjoy features such as collision warnings, lane change assistance and driving skill assessments even if your car doesn't actually have any of those features included.
Shaped like a disc, the CarVi is equipped with a 720p camera, three-axis accelerometer, microphone, speaker and a WiFi unit that allow it to connect to your smartphone wirelessly. As you drive along, the camera captures footage of what's happening in front of you and analyzes it in real time to provide feedback. For example, it will sound an alert if you're driving too close to the car in front of you or wandering out of your lane.
CarVi is a fine example of how you don't always need to spend top dollar to upgrade an existing product, in this case a car. Innovative technological interventions have made it easier than ever to enjoy newer high-tech features using simple upgrades and additions.
