Investigating perceived emotions and affects of a scene, and the user satisfaction with motion effects in 4D movies

Abstract

The primary objective of this study was to investigate the intensity of perceived affect and emotion of a scene in relation to individual empathy ability and the rotation angle of a seat's motion caused by 4D movie motion effect. The secondary objective was to identify the causal factors that affected satisfaction with a motion effect. Although 4D movies have received increasing attention from the users of audiovisual content, user-centered research related to motion effects has rarely been conducted. Thirty-six participants who were grouped according to their empathy ability, viewed 10 4D movie clips and answered 2 questions related to 1) the perceived affect and emotion felt from the scenes and 2) satisfaction with the motion effects. The participants who had a high empathy ability indicated a stronger perceived affect and emotion during a scene than the participants who had a low empathy ability. A motion effect elicited different perceived emotions and affects between the two groups. The perceived temporal appropriateness, physical appropriateness, understandability, and disturbance of a motion effect affected the participants' satisfaction. This is a pioneering research related to the motion effects of 4D movie; therefore, these results could be helpful in providing insight for 4D effect designers of contents industry.
