Lullaby: Capturing the Unconscious in the Sleep Environment

Research has shown that environmental factors can be one of the major causes of poor sleep quality and interrupted sleep [8], which can contribute to daytime sleepiness and fatigue. In particular, a room that is too warm [11], has improper lighting [10], or is noisy [1] can have a negative impact on sleep. While some of these environmental factors are observable, others may be subtle. Individuals who have poor sleep quality can often have difficulty evaluating the cause or severity of their sleep difficulties [3]. We present preliminary results of an ongoing study of Lullaby, a capture and access system for the sleep environment, and discuss some aspects of designing capture and access for unconscious experience.
