Proposal of a Home Aquarium Using Change Viewpoints

The aquarium market is growing and becoming popular. Many aquariums and zoos attempt to satisfy the visitors’ new experiences based on considering the characteristics of each animal and fish. For example, the Asahiyama Zoo has designed a water tank to allow visitors to see seals moving up and down and penguins swimming like flying in the sky. We focused on a home aquarium in this research. Because there are only a few studies aimed at enjoying a home aquarium. When we enjoy a home aquarium, the existing one-sided viewpoint method of seeing the inside of the aquarium from the outside of it has a blind spot and cannot be seen. That means the one-sided viewpoint method from outside limits the various information inside the aquarium. Therefore, we experimented with the effect of changing viewpoints when we see a home aquarium. In the experiment, participants saw the movie recorded inside a home aquarium with four different viewpoints. One existing viewing point and three new viewpoints. Next, they evaluated these four movies using the SD method. After that, we conducted Factor Analysis using the evaluated results of the SD method. As a result, we extracted the following three factors: 1) Novelty factor, 2) Dynamism factor, and 3) Unity factor. However, the factor scores differed depending on the home aquarium’s viewpoints. That means we feel these three impressions when we see the home aquarium. Based on the results, we created a new device for a home aquarium with the keyword ‘changing viewpoints.’
