Development of metaphor-based interface design for VR manipulator

Abstract

This research aims to establish a systematic approach to the development of metaphor and corresponding user models for VR interface design. Metapho rs have been used in various domains as means to extend the user’s mental models. Current research effort regarding VR interface design is mainly concentrated on static objects or visual information. In contrast, this research focuses on more integrating and dynamic aspects of VR interface such as interaction activities, task sequences, and operational motions. Finding principles for the selection and composition of appropriate metaphors is crucial for systematical dealing with this problem. User observation and task analysis were conducted to identify the cognitive difficulties that users face in performing the operations on VR objects. A VR manipulator that spatially provides the dynamic information and history was designed to mitigate those difficulties and cognitive load.
