We are witnessing a fundamental shift in how humans interact with technology, as voice-based interactions become not only common, but often the primary user experience. From voice notes to smart devices and AI assistants.
Over the last twenty years Graphical User Interfaces (GUIs) have been dominant, but we are now seeing the rapid emergence of Conversational User Interfaces (CUIs) enabled by Large Language Models (LLMs). These new AI-powered conversational experiences are transforming the potential of voice and natural language as an interaction method, creating an open-ended, adaptive, and conversational user experience.
This shift moves beyond the "visual templates" model of the past to a new era of responsive, context-driven interactions with apps and services. We have new opportunities to improve the user experience, build on all that we’ve learned over the past few decades of designing Transparency & Control moments in visual GUIs, and explore new opportunities and challenges in adapting those experiences through the addition of a conversational, voice-first approach.
This report presents the feedback and discussions from a series of global workshops exploring these new opportunities and challenges. The workshops engaged academics, civil society, industry, legal professionals and other policy stakeholders in Berlin, Madrid, Seoul, Brasília, San Francisco, and Delhi.
Participants engaged in Design Jam workshops to evaluate scenarios across a range of Transparency & Control moments, with a focus on voice as the input, to what a great user experience might look like in these moments.
The insights from these Design Jams are shared here as early insights into this area. As the program evolves, we intend to explore and publish additional insights on this topic.
