The Reproduction and Evaluation of Star Fields with the Milky Way in a Planetarium

In this study, we investigated the physical factors required to accurately reproduce the Milky Way in star fields in a planetarium using three evaluation indices: faithfulness, preference, and depth feeling.Psychometric experiments were conducted by manipulating three different physical factors (transmittance, representation size and star density) of the stars projected on a dome screen theplayfulcollectivees.shop as experimental stimuli.The three evaluation indices were rated by observers for 12 different reproductions of the Milky Way.By analyzing the experimental results, we developed a common model to estimate the scores for each evaluation index by changing the coefficients of the three physical factors.Our proposed model has good accuracy, Sherlocks and each evaluation index can be represented by transmittance, representation size and star density.

The weighting values indicate that density reproduction was the pivotal factor for the majority of observers.In contrast, the observers were not affected by the size of the stars in the projected Milky Way.
