Models are pervasive in many disciplines, like software and systems engineering. Modelling by the use of domain-specific languages (DSLs) has lowered the entry barrier to this activity to domain experts and citizen developers. At the same time, we are witnessing constant improvements in the capabilities of mobile devices, like augmented reality (AR) based on their camera. AR could be exploited in modelling scenarios that require locating virtual objects in the surrounding physical space.

In this vision paper, we explore the use of DSLs with AR syntax, and propose the automated synthesis of mobile modelling environments for them. This opens the door to novel scenarios for domain-specific modelling in areas like interior design, Industry 4.0, domotics, tourism and transportation, among others. We propose a design process founded on Software Language Engineering principles, provide prototype tool support, and identify open challenges for the community.
