Abstract
OBJECTIVE
Two experiments examined whether prior interaction within an immersive virtual environment (VE) enabled people to improve the accuracy of their distance judgments and whether an improved ability to estimate distance generalized to other means of estimating distances.
BACKGROUND
Prior literature has consistently found that users of immersive VEs underestimate distances by approximately 50%.
METHOD
In each of the two experiments, 16 participants viewed objects in an immersive VE and estimated their distance to them by means of blindfolded walking tasks before and after interacting with the VE.
RESULTS
The interaction task significantly corrected users' underestimation bias to nearly veridical. Differences between pre- and post-interaction mean distance estimation accuracy were large (d = 4.63), and significant (p < .001), and they generalized across response task.
CONCLUSION
This finding limits the generality of the underestimation effect in VEs and suggests that distance underestimation in VEs may not be a road block to the development of VE applications.
APPLICATION
Potential or actual applications of this research include the improvement of VE systems requiring accurate spatial awareness.
