Lou

System interaction within the Lou ecosystem
App, vehicle, and parking meter in dialogue
Concept
What would a parking process look like if it was designed entirely around the user?
Lou represents a visionary user interface for an external parking assistant, offering a forward-thinking response to the challenges of urban parking.

The concept not only enables early identification of optimal parking spaces but also facilitates smart management of parking durations and automated payment processes. In doing so, Lou takes into account key stakeholders – including local authorities, residents, and visitors alike.
The ultimate goal of Lou is to make up-to-date parking information effortlessly accessible to anyone seeking a stress-free parking and payment experience. Through thoughtful communication between the user, the device, and the parking meter, Lou transforms parking into a pleasant and seamless process. Welcome to a future where parking is smarter and smoother than ever before!

As the driver moves away from the parked vehicle, Lou connects to the smartphone within a defined range.
When returning to the vehicle, the interaction seamlessly shifts back to the in-car interface.
Challenge
Urban parking is a daily challenge shaped by limited space, unclear regulations, and inefficient communication between drivers and parking infrastructure.

Through research and field observation, it became clear that current systems focus mainly on individual transactions – finding a spot, buying a ticket – while neglecting the overall user journey and interconnected stakeholders such as residents, visitors, and city authorities.

Prototyping
Lou
To better understand how the gadget would function inside the vehicle, we built a series of physical prototypes during the design process. Working with tangible models helped us explore the device’s size, placement and tactile qualities in a realistic setting.

By placing the prototypes inside a car, we were able to observe how drivers might reach for the device, how visible it would be within the interior, and how the interaction could feel during the parking process. These explorations helped refine the form and interaction of the gadget.
Early sketches explored how the physical interface of Lou could communicate parking information in a simple and intuitive way.
Different form studies investigated how the device could tilt, rotate and provide visual feedback.

By positioning the assistant, the interface becomes a subtle yet accessible touchpoint that connects the vehicle with the user’s smartphone and the surrounding parking infrastructure.

Concept
The smart parking terminal presents itself as a minimal, display-based interface that visualizes the surroundings and highlights parking availability through color-coded feedback.

This seamless integration of digital and physical systems creates a smooth and efficient parking experience. The streamlined design focuses on essential functions while leaving space for future extensions and administrative use, such as automated reporting of parking violations.
