Virtual reality's new technology and theory makes it somewhat expensive and puzzling to practitioners. Effectively using its inherent characteristics requires understanding VR's terms and its variations.
Realism debates whirl around what levels of realistic detail are needed and affordable.
This is a manipulable 3D object that enables viewers to observe the structure of an atom from all perspectives. Some instructional contexts depend on specific realities, i.e., contexts that never vary. Scientists seeking medical cures must observe atomic particles in specific places and with specific behaviors when manipulated. Explorers encounter unspecified variations ranging from air quality to zoological specimens. VR's range of realities enables instructional designers and practioners to increase contextual complexities as learners transition from novices to experts.
