Abstract: Natural User Interface (NUI) is the 4th paradigm in the user interface after Command Based Line (CBL), Graphic User Interface (GUI) and Windows, Icon, Menu &Pointer (WIMP). NUI allows users to make movements and displays on the virtual world resembling human movements in the real world. There are two components in NUI: surface gestures and motion gestures. Device development in surface gestures involves input in touch (taps, swipes, press and drag) and motion gestures (hand, arm, eye, body and head). Hand-tracking technology has been widely used in the field of Virtual Reality (VR).It allows users to use hand gestures to interact with the virtual environment. Research on acquiring the hand gestures of real user’s needs is still lacking and so is the implementation. This paper presents results of a guessability study of actual user hand-gesture movements in command development for virtual heritage. A total 312 gestures were obtained from 13 respondents for 24 selected tasks. This study proposes a list of specific gestures set by the actual users. The implication from the study is relevant to the design of hand gestures for virtual heritage interactions.
