NUX Characters - interaction with voice assistants in Virtual Reality

NUX Characters is a Virtual Reality environment designed for testing different voice assistants. We prepared five environments covering various styles and personas of the assistants: a virtual human, a virtual animal, a cartoon-like character, a non-humanoid robot and a humanoid robot. The common feature of the environments is the mechanics of the user's task - to collect the items hidden in the location while the assistant helps in this quest by giving verbal hints. The environment can be used for the investigation of user experience, impressions and preferences towards virtual assistants as well as the traits attributed to them, which can be applied to optimize design decisions for the VR environments supporting voice user interface.
