Planetariums have been widely used for entertainment and astronomy education by using domes, projectors, and light sources to simulate the starry sky under physical and technical restrictions. What type of starry sky do visitors hope to see at a planetarium? They surely want to see an appealing starry sky, but is an appealing starry sky one that appears perceptually faithful to the actual night sky? Or is it sufficient if it simply looks favorable, even if it is not physically or perceptually accurate? This paper analyzes the relationship between fidelity and preference in planetarium starry skies, focusing on gender differences to determine the ideal star image that visitors seek.
Following our other study (submission No. : C000008), this experiment projected star images of the Orion region onto a 23-meter-diameter dome screen. Participants evaluated the fidelity and preference for nine projection patterns differing in star size, brightness, and color using a 5-point Likert scale in a psychometric experiment. A total of 47 observers (33 males and 14 females) ranging in age from young to elderly participated in the experiment.
For the fidelity evaluation, the observers compared the projected sky to their memory of the actual night sky. For the preference evaluation, no comparison was provided, and ratings were based solely on subjective judgment.
The results showed that fidelity ratings increased with projection patterns featuring smaller star sizes. For preferability ratings, darker luminance projection patterns significantly reduced the perceived preference. The results showed that while preferences for star reproduction differed between males and females, no significant gender difference was found in evaluations of faithful star reproduction. Male observers preferred faithful star reproduction. In contrast, female observers did not find faithful star reproduction preferable and instead evaluated brighter star reproduction as the preferred reproduction. Furthermore, these results were independent of astronomical observation experience.
