Collaborative Problem Solving in Mixed Reality: A Study on Visual Graph Analysis

This study involving 72 participants across three languages demonstrates that while nominal groups serve as a crucial benchmark for evaluating collaborative virtual environments, 3D graph representations in mixed reality do not inherently yield better collaborative problem-solving outcomes than individual performance.

"Who wants to be nagged by AI?": Investigating the Effects of Agreeableness on Older Adults' Perception of LLM-Based Voice Assistants' Explanations

This study of 70 older adults reveals that while high-agreeableness in LLM-based voice assistants generally enhances trust and likability, the preference for warmth over clarity shifts depending on the context (routine vs. emergency) and the user's own personality, highlighting the need for adaptive, personalized AI explanations.
