THE EFFECT OF DYNAMIC RIM LIGHTING ON USERS VISUAL ATTENTION IN THE VIRTUAL ENVIRONMENT

We conducted a study in the virtual environment to explore the influence of three types of lighting (dynamic rim lighting vs. static rim lighting vs. no rim lighting) on users’ visual attention, and the lighting’s potential effects on the users’ preference/choice-making. We recruited 40 participants to complete a virtual grocery shopping task in the experiments, and after the experiment, the participants were given a survey to self-report their experience. We found that (1) the users do not prefer to collect virtual objects with dynamic rim lighting than virtual objects with static rim lighting; (2) the users do not prefer to collect virtual objects with rim lighting than virtual objects without lighting; (3) if the virtual object has a warm-colored texture, it’s more likely to be chosen when it has dynamic rim lighting compared with static rim lighting or no rim lighting; and (4) properties of the dominant color on the texture of a virtual object, such as the B value is a good predictor in predicting if the user tends to choose the object with rim lighting or without rim lighting, while R, B and Lightness values are plausible in predicting if the user tends to choose the virtual objects with dynamic rim lighting or static rim lighting.
