L+R’s Ivan Leider, Gautier de Lataillade, and Kelvin Harron announced as speakers for xr & mobile game developerCon

xr & mobile game developerCon at next.app will bring XR creators, mobile game developers, designers, and platform builders to CityCube Berlin from October 7-9, 2026. Produced by Mobile Seasons, the team behind developer communities including flutterCon and droidCon, the conference is positioned as a new forum for the mobile-born practitioners shaping spatial computing. Ivan Leider, Gautier de Lataillade, and Kelvin Harron have been announced as speakers for the inaugural event.

The conference arrives at a consequential moment for the industry. Wearables, smart glasses, XR headsets, game engines, mobile frameworks, and AI-native interfaces are beginning to converge into a more coherent developer ecosystem. For L+R, that convergence is not theoretical. It reflects a body of work across spatial computing development, smart-glasses software, mobile infrastructure, and privacy-aware interaction design.

Gautier will speak about Media View, L+R’s open-source spatial media viewer for Meta Quest. Built with Meta and launched alongside Meta’s Spatial SDK at Meta Connect 2024, Media View uses Kotlin and the Meta Spatial SDK to show how mobile development patterns can extend into immersive Quest experiences. Gautier will also share a case on how L+R extended Media View into a media player platform for a to-be-announced special new app, demonstrating how a focused Quest application can evolve into reusable infrastructure for spatial media experiences.

Ivan, Gautier, and Kelvin will bring perspective from L+R’s recent practice in this space, including smart glasses application infrastructure, Ephemeral Perception, and applied development with Meta’s Device Access Toolkit and Ray-Ban Display glasses web apps. Together, those efforts point to the same underlying shift: spatial computing is becoming less of a standalone category and more of a practical extension of mobile product strategy, design systems, and software engineering.

That mobile foundation is central to the conference’s premise. next.app describes xr & mobile game developerCon as a place for developers to move beyond the rectangular screen and build the next generation of XR and spatial computing experiences for smart glasses and headsets. The first announced speaker lineup includes practitioners across XR, mobile games, spatial software, and developer tooling, with Ivan, Gautier, and Kelvin representing L+R’s hands-on approach to building in the field.

The announcement also extends the work behind Meridian Meetups, L+R’s community initiative for mobile developers, designers, and technologists exploring spatial computing. Through Meridian, L+R has focused on giving the mobile ecosystem a practical path into XR: not as a speculative frontier, but as a new application layer for teams already fluent in mobile product design and engineering. The community’s recognition as a Lovie Award-winning initiative underscores the importance of building shared knowledge around emerging platforms.

As wearables become more capable and XR platforms mature, the next generation of computing will be shaped by the people who can connect hardware, software, privacy, and human context. L+R is proud to contribute to that conversation in Berlin, alongside the developers and designers building the tools, interfaces, and experiences that will define what comes next.
