Abstract:
We investigate verbal learning and cognitive map development of simulated layouts using a non-visual interface called a virtual verbal display (VVD). Previous studies have questioned the efficacy of VVDs in supporting cognitive mapping (Giudice, Bakdash, Legge, & Roy, in revision). Two factors of interface fidelity are investigated which could account for this deficit, spatial language vs. spatialized audio and physical vs. imagined rotation. During training, participants used the VVD (Experiments 1 and 2) or a visual display (Experiment 3) to explore unfamiliar computer-based layouts and seek-out target locations. At test, participants performed a wayfinding task between targets in the corresponding real environment. Results demonstrated that only spatialized audio in the VVD improved wayfinding behavior, yielding almost identical performance as was found in the visual condition. These findings suggest that learning with both modalities led to comparable cognitive maps and demonstrate the importance of incorporating spatial cues in verbal displays.

Although this chapter was
Although this chapter was published before the ACM- TAP paper (above), it reflects work which is a follow-up to that research. It addresses the problem with environmental transfer found in the previous work and clearly demonstrates that adding spatial information to the verbal signal, e.g. hearing “left” from the listener’s left side, improves cognitive map development. Unexpectedly, this simple addition led to reliably better results than including ideothetic cues via real rotation in the VVD. These results have significant relevance to the design of both virtual and real-time verbal interfaces and definitively demonstrate the efficacy of virtual verbal displays (VVDs) for spatial knowledge acquisition and pre-journey learning of virtual layouts and environmental transfer to accurate navigation of the corresponding physical spaces.
