The AR project for Mercedes-Benz is an augmented reality application that lets users configure a car's appearance, features, and equipment without leaving the showroom. Users can select colors and shades from the Mercedes collection, visualize them on a real car through their device's screen, and customize wheels, design, interior layout, upholstery, seat materials, features, and additional functions. The app also includes a voice assistant that highlights the car's advantages and answers user questions, integrating seamlessly with the sales department's CRM system for booking test drives and connecting with sales.
