  The human-centered artificial intelligence (HCAI) design approach, the
user-centered design (UCD) version in the intelligence era, has been promoted
to address potential negative issues caused by AI technology; user experience
design (UXD) is specifically called out to facilitate the design and
development of human-centered AI systems. Over the last three decades, user
experience (UX) practice can be divided into three stages in terms of
technology platform, user needs, design philosophy, ecosystem, scope, focus,
and methodology of UX practice. UX practice is moving towards the intelligence
era. Still, the existing UX paradigm mainly aims at non-intelligent systems and
lacks a systematic approach to address UX for designing and developing
human-centered AI products and systems. The intelligence era has put forward
new demands on the UX paradigm. This paper proposes a "UX 3.0" paradigm
framework and the corresponding UX methodology for UX practice in the
intelligence era. The "UX 3.0" paradigm framework includes four categories of
emerging experiences in the intelligence era: ecosystem-based experience,
innovation-enabled experience, AI-enabled experience, and human-AI
interaction-based experience, each compelling us to enhance current UX practice
in terms of design philosophy, scope, focus, and methodology. We believe that
the "UX 3.0" paradigm helps enhance existing UX practice and provides
methodological support for the research and applications of UX in developing
human-centered AI systems. Finally, this paper looks forward to future work
implementing the "UX 3.0" paradigm.
