Book reading has numerous positive side effects, yet the amount of time that people spend reading is decreasing. Science has proved that the neurological processes of generating mental images, e.g. when reading, are similar to those of perceived images, thus visual perception may affect visual imagery - and vice versa.The present study investigates how reactive light can enhance text-based experiences, herein audio- & e-books, and ultimately make people spend more time on such media. A design framework was developed based on ‘motivated lighting’ principles, used in stage lighting, in which light qualities are selected based on text cues.
 
An experiment was developed, with the initial aim of getting a brief understanding of how light and stories correlate, and to evaluate if light has an effect on imagery, emotions and motivation. In the experiment, subjects were presented to different types of ambient light, while listening to audio-stories of different moods. Qualitative and quantitative data was collected from self-assessment and heart rate.The combination of experiment findings and literature reveal that darkness is best utilized to improve imagery, whereas reactive lighting may enhance experiences by increasing motivation and emotional response - if used correctly. 
 
The conclusion of this investigation supports light as a tool to enhance story experiences, while opening up for more questions that deepen the understanding of the relationship between visual imagery and visual perception.
