The field of human-robot collaboration is moving towards more effective and intuitive communication between humans and robots. Research is focusing on the development of adaptive, context-aware avatar interactions and multimodal communication cues to enhance team coordination and reduce workload. Personalized communication and task assistance are also being explored as key factors in improving human-robot collaboration. Noteworthy studies include one that found verbal communication to be more effective than non-verbal cues in reducing mental demand and effort in high-stakes environments, and another that highlighted the need for multimodal strategies beyond linguistic pluralization in group-sensitive conversation design.
