Thematic design and efficiency in virtual environments using metaphors

The use of metaphors in designing virtual environments unifies design elements and improves efficiency and interaction. Metaphors informing VE design relate visual and sonic cues and structural elements using a connecting theme. Thematic design based on metaphor capitalises on iconic familiarity and existing user experience. The design metaphor affects relational and virtual reality perception of directedness, enclosure, engagement, navigation, and presence. The design metaphor relates semantic-based construction processes and agent behaviours.
