Psychological Evaluation for Images/Videos Displayed Using Large LED Display and Projector
2020
Display of images/videos on a big screen/display, such as digital signage, projection mapping, etc., is becoming popular in the area of entertainment, advertisement, and so on. A comparison of the usage of an LED display and a projector is important for such applications. We have prepared an experimental environment where two types of projection/display using a 200 inch LED display and a 200-inch screen and a projector. Also, two brightness conditions, light-on and light-off, and two types of contents, art content and text content were used for the experiment. Under a total of eight types of environments, we carried out a psychological experiment using 24 participants. Each subject filled a questionnaire based on a five-point semantic differential scale. Based on the analysis of the result, it was revealed that the combination of art content, light-off, and LED display gives far better results than other combinations.
