devcom 2025 – Speaker: UX Roundtable & Cross-Platform Design

As part of devcom 2025 in Cologne, I hosted a roundtable discussion on UX and cross-platform design in modern game development.

The session brought together designers, producers, and researchers from studios across Europe to exchange methods for improving player experience and UI coherence across different hardware and input systems.

Focus topics:

• UX pipelines for cross-platform titles

• Accessibility and interface scalability

• Emotional design consistency between PC, console, and mobile

• Knowledge-sharing between indie and AAA environments

The roundtable aimed to create an open, collaborative space where participants could compare production workflows, toolchains, and research-driven UX practices.

As a speaker and facilitator, I summarized the key outcomes for the community and documented them as part of my ongoing UX pattern research project.
