Participants learned the layout of large-scale "virtual buildings" through extended navigational experience, using "desk-top" (i.e., nonimmersive) virtual environments (VEs). Experiment 1 recreated a study performed in a real building (P. W. Thorndyke & B. Hayes-Roth, 1982). After overcoming initial disorientation, participants ultimately developed(More)
During navigation, humans combine visual information from their surroundings with body-based information from the translational and rotational components of their movement. Theories of navigation focus on the role of visual and rotational body-based information, even though experimental evidence shows they are not sufficient for complex spatial tasks. To(More)
The following abstracts are from recent issues and the forthcoming issue of ACM's <i>Transactions of Computer Human Interaction</i> (ToCHI). They are included here to alert <i>Interactions'</i> readers to what research is being done in the field of Computer Human Interaction. The complete papers, when published, can be found in ACM's Digital Library at(More)
Books listed below that are marked with a † have been selected for review in a future issue, and reviewers have been assigned to each. Authors and publishers who wish their publications to be considered for review in Computational Linguistics should send a copy to the book review editor,evant books received will be listed, but not all can be reviewed.(More)
Navigation is the most common interactive task performed in three-dimensional virtual environments (VEs), but it is also a task that users often find difficult. We investigated how body-based information about the translational and rotational components of movement helped participants to perform a navigational search task (finding targets hidden inside(More)
The effect of proprioceptive information and environmental characteristics on spatial learning was investigated when participants repeatedly navigated complex three-dimensional (3D) virtual mazes. Proprioceptive information, provided by viewing the mazes using a head-mounted display, was found to have little effect. The primary environmental characteristics(More)
Data is presented from virtual environment (VE) navigation studies that used building-and chessboard-type layouts. Participants learned by repeated navigation, spending several hours in each environment. While some participants quickly learned to navigate efficiently, others remained almost totally disoriented. In the virtual buildings this disorientation(More)
Participants used a helmet-mounted display (HMD) and a desk-top (monitor) display to learn the layouts of two large-scale virtual environments (VEs) through repeated, direct navigational experience. Both VEs were ''virtual buildings'' containing more than seventy rooms. Participants using the HMD navigated the buildings significantly more quickly and(More)
Two experiments investigated components of participants' spatial knowledge when they navigated large-scale ''virtual buildings'' using ''desk-top'' (i.e., nonimmersive) virtual environments (VEs). Experiment 1 showed that participants could estimate directions with reasonable accuracy when they traveled along paths that contained one or two turns (changes(More)
