Zusammenfassung: | The visible orientation of human eyes creates some transparency about
people's spatial attention and other mental states. This leads to a dual role
for the eyes as a means of sensing and communication. Accordingly, artificial
eye models are being explored as communication media in human-machine
interaction scenarios. One challenge in the use of eye models for communication
consists of resolving spatial reference ambiguities, especially for
screen-based models. Here, we introduce an approach for overcoming this
challenge through the introduction of reflection-like features that are
contingent on artificial eye movements. We conducted a user study with 30
participants in which participants had to use spatial references provided by
dynamic eye models to advance in a fast-paced group interaction task. Compared
to a non-reflective eye model and a pure reflection mode, their combination in
the new approach resulted in a higher identification accuracy and user
experience, suggesting a synergistic benefit. |
