VR Scaling Experiment

Analyzing the effects of contextual cues and display medium (HMD vs Screen Display) on spatial perception in virtual environments.

Step 2

Scale Virtual Chair

This experiment is a two by two between-subjects factorial design. Each subject will be given 6 objects (3 pieces of furniture and 3 amorphous shapes) to study for 3 minutes each. After studying the object, the subject will be asked to scale a virtual version of the object six times. Each time will start with a random scale. The two variables are the level of contextual cues in the environment, and the medium of interaction (HMD vs Computer Monitor).

The following hypotheses guided the data analysis.

  1. VR is more accurate than Computer Displays at translating scale in virtual environments
  2. Presence is a mediating factor in spatial scale perception in virtual environments
  3. Higher levels of contextual cues will lead to more accurate perception of scale
  4. Subjects with better spatial ability will more accurately scale the objects in the virtual world.
