Intelligent system will exist widely in the future life and work. This work aims to analyze key issues in human-intelligent system collaboration from both technology-centric and experience-centric perspectives, to deal with the challenges in interactions between human and intelligent system. This work combed the evolution and research scope from human-computer interaction to human-intelligent system collaboration, and put forward a comprehensive research framework from both technology-centric and experience-centric perspectives. From the features of intelligent system, emerging problems brought by human-intelligent system collaboration were proposed, and the ways for promoting hu-man-intelligent system collaboration were discussed from experience-centric perspective. Future trends of hu-man-intelligent system collaboration were summarized on this basis. A three-stage framework of human- computer inter-action evolution is proposed. Key issues in human-intelligent system collaboration from technology-centric perspective are concluded, including degree of agency, adaptive learning and correction, context-sensitive and proactive interaction. Experience-centric issues like explainability, trust, affective interaction, fairness and accountability are discussed. Trends of human-intelligent system collaboration are described as comprehensive, diverse, and systematic.
