Abstract
With the gradual lowering of technological threshold and the increasing penetration rate of virtual reality and augmented reality devices, virtual humans (VHs) are increasingly intermediating users and information systems in various contexts. As a projection of VH's anthropomorphic stability, a set of personality traits is used to present contents and guide the generation of human-like behaviors. The large variety of VHs poses a challenge to their systematic design. This paper tries to establish an approach to practising a personality-centred design with consideration of other accompanying components. At first, the integrity of the VH personality is constructed, along with a personality model of VHs different from those of real humans. Then two studies are carried out to reveal the correspondence between personalities and roles of VHs, and between personalities and VH behaviors. Study 1 provides design cards for VH roles in specific contexts, as a set of proper personalities and typical behaviors accordingly. The perception experiment of Study 2 provides clues for utilizing multimodal signals in certain behaviors and enriches the design cards. This paper aims to lay specifications and references when designing for digital experience, with VHs as the main human-computer interface.

A personality-centred design approach for virtual humans on correspondence with roles and behaviors
With the gradual lowering of technological threshold and the increasing penetration rate of virtual reality and augmented reality devices, virtual humans (VHs) are increasingly intermediating users and information systems in various contexts. As a projection of VH's anthropomorphic stability, a set of personality traits is used to present contents and guide the generation of human-like behaviors. The large variety of VHs poses a challenge to their systematic design. This paper tries to establish an approach to practising a personality-centred design with consideration of other accompanying components. At first, the integrity of the VH personality is constructed, along with a personality model of VHs different from those of real humans. Then two studies are carried out to reveal the correspondence between personalities and roles of VHs, and between personalities and VH behaviors. Study 1 provides design cards for VH roles in specific contexts, as a set of proper personalities and typical behaviors accordingly. The perception experiment of Study 2 provides clues for utilizing multimodal signals in certain behaviors and enriches the design cards.
