Towards Realism: Selection Techniques for Virtual Human Interaction

Virtual community simulation has been engaged on extensive research studies with rapid usage of virtual worlds. Realistic interaction with virtual humans is a complex research area in such kind of simulations since significant concern need to be devoted in order to simulate the social interactive phenomena. This research proposes a selection process for user interested virtual humans. The implemented selection techniques proposed to overcome limitations in existing virtual object selection techniques such as memory overhead and cognitive effort over the users. System prototype is integrated with multimodal interfaces to provide an immersive user experience in human computer interaction. Studying of the users has been conducted to comparatively evaluate proposed selection techniques with ray casting metaphor which is widely presented in games and simulations. Experiment has been conducted in order to evaluate both ideal and walking states of virtual humans. Results of the user study shows the suitability of proposed head oriented metaphors to interact in simulations which are related with virtual humans.
