Wayfinding is the cognitive component of moving around in an environment. It is a decision making process which needs clarity and metaphors can be useful. Wayfinding needs high level thinking, planning and decision-making related to user movement. It involves:
spatial understanding (see chapters about spatial dimensions).
planning tasks, such as determining the current location within the environment, determining a path from the current location to a goal location and building a mental map of the environment.
Environment legibility: think of paths (linear), edges (enclosing), districts (quickly identifiable), nodes (gathering points), landmarks (static objects).
Landmarks: for directional cues and local for decision-making by providing information.
Compasses: provide directional cues, great for implementation in maps.
Signs
Trails: helps users to retrace their steps.
Reference Objects:well-known objects like chairs and human figures to determine size in virtual reality.
User-Controller-Centered
There are several strategies that designers and developers can handle to support the challenges that the human perceptual system and VR-hardware will keep on facing.
Field of View (FOV): larger FOV (> 40-80 degrees) reduce head movement. Small FOV's lead to cyber sickness.
In virtual worlds, way finding can be crucial, an efficient travel technique needs to be combined with an overview of routing and knowing where to go.
Maps: most common in daily life, but very complex to design for in virtual environments. Needn't necessarily be a spatial representation, but can also categorise and place hierarchical structure at its core. vs
Motion Cues: - the peripheral vision provides strong motion cues (direction, velocity, orientation during movement), - additional vestibular cues ( & balance, which usually are related to embodied self-motion cues) are necessary as well.
Multi-sensory Output: - (a map which contours are raised so they can be sensed by touch as well as sight.) Tactile cues can aid in the formation and usage of spatial memory. - Audio use can be used as well.
