There are a number of important differences. One is that it is a system optimized for the car, unlike the smartphone voice assistants. Chris proactively supports the driver, cancelling out distraction by a glanceable display and offers linear, easy to process information. The combination of voice, hand gestures and glanceable display solves the issues that current voice assistants have, and make the overall interaction more intuitive and easy to use. The final key difference to other in-car systems is that it works in all cars, including vehicles up to 15-year-old, and with all recent smartphones based on iOS or Android.
