Human-AI Interaction for Time-Critical Sensemaking in Missing Persons Investigations

Every year an estimated 200,000 people go missing in the UK alone. Missing persons investigations involve challenging time-critical sensemaking tasks based on fragmented data sources. This paper describes a mixed-methods participatory study evaluating data science and AI-driven techniques (summarisation, fact extracti…

Design Activity Simulation: Opportunities and Challenges in Using Multiple Communicative AI Agents to Tackle Design Problems

Large Language Models (LLMs) can enhance structured design thinking, yet existing copilot approaches integrate them into human workflows rather than exploring their autonomous potential. This paper investigates how LLM-based communicative AI agents can independently tackle open-ended design problems and how their stre…

Seeing and Touching the Air: Unraveling Eye-Hand Coordination in Mid-Air Gesture Typing for Mixed Reality

Mid-air text entry in mixed reality (MR) headsets has shown promise but remains less efficient than traditional input methods. While research has focused on improving typing performance, the mechanics of mid-air gesture typing, especially eye-hand coordination, are less understood. This paper investigates visuomotor c…
