Interaction Design Master Thesis

Lagom is a system that allows users to access most of the information and functions of the car through simple gestures in three levels of gestural interaction. First small gestures over a tangible display in the steering wheel, second a combination of larger gestures in the central console and the third level the car recognizes gestures from users enhancing the communication between car and users by including sound, touch, and visual graphic user interfaces. This project was design based on an experience design methodology, including techniques such as experience prototyping and user studies.

The design process for this concept started like any other design project with a sketching process, but to be able to do hardware sketching, the process has to narrow to a specific element that will be prototyped. In this case, the element that was designed was the steering wheel.

Lagom is a Swedish word meaning "just the right amount." The word can be variously translated as "in moderation", "in balance", "perfect-simple", and "suitable".

The design consists of 4 key elects to display a menu in the key interaction areas for easy access and safety.
It combines the tactile experience of a button or knob with a subtle gesture over the tangible interactive surface.
