Mood lighting system reflecting music mood

Abstract

The emotional impact of music or color can be maximized if they are used together. This article presents a mood-lighting system that automatically detects the mood of a piece of music and expresses the mood via synchronized lighting. To do this, the relationship between mood words and colors was analyzed via a web questionnaire (n 5 202) on moods associated with music and colors. Data analysis generated lighting scenarios reflecting changes in the mood of music. Each piece of music was divided into several segments using structural analysis, with the mood of each segment detected by the mood classification module using the neural network. A matching color was then assigned. The best performance of our mood classification module was <70%, which is not sufficient for commercial use; however, this figure is high enough to show the potential of this approach.

Colour Coded Emotion Classification in Mental Health Social Media

“…NLP is only one aspect of the project, with the display of mood colours being the other. Mapping certain colours to moods will be different for each user so groups of colours will have to be assigned to each mood using the most common colours as a starting map (Moon, Kim, Lee, & Kim, 2013).…”

“…In a study to display the mood of music via coloured lighting, Moon, et al, (2013) used Thayer's emotion model to determine the emotion. The Thayer emotional model is a 2D grid of emotions plotted against arousal and tension (Thayer, 1990).…”

“…The Thayer emotional model is a 2D grid of emotions plotted against arousal and tension (Thayer, 1990). Because this model doesn't just use emotion adjectives, there is less ambiguity (Moon, Kim, Lee, & Kim, 2013).…”

The discussion of the relationship between lighting and music in a lighting show

“…16 Music that evokes positive emotions is associated with bright colors. 17 Current research shows that the phenomenon of sound-light synaesthesia is universal. However, few studies have investigated the fusion of sound and light.…”

“…For example, the middle “C” key on a piano might represent red, but notes three octaves higher than it may be green; a sharp knock on the table may cause a faint but clear narrow flash 16 . Music that evokes positive emotions is associated with bright colors 17 …”
