Defining attributes of an immersive microcar configurator for exploring user requirements

Abstract

Light electric vehicles (LEV) present a promising solution for sustainable urban mobility but currently occupy a small share of the market. To better understand user preferences and decision-making processes, we developed a Mixed Reality Configurator (MIRCON) for Microcars. Mixed Reality (MR) provides an immersive, interactive environment that allows users to visualize and experience the vehicle customization process—particularly given the compact size of Microcars. MIRCON is designed to present users with a set of configuration options, including seating arrangements, powertrain choices, safety features, and general comfort and design elements. This contribution describes the development of a structured set of attributes and corresponding user guidance for configuring an LEV. The methodology involves literature review, expert workshops, and usability testing to refine the MIRCON's user interface (UI). As a result, key insights led to a structured sequence of categories and selection options, ensuring clarity and ease of navigation.
