ShutEye is a research application that was developed by Intel Labs Seattle and the University of Washington for Android-based mobile phones. The intent of ShutEye was to help improve people's awareness about healthy sleep hygiene—that is, the practices that are believed to promote improved quality of sleep.
A glanceable display on the wallpaper of an individual's mobile phone provided recommendations about common activities that are known to impact sleep relative to sleep and wake times: consuming caffeine, napping, exercising, eating heavy meals, consuming alcohol, ingesting nicotine, and relaxing. For example, the individual could quickly glance at their phone to see if having a cup of coffee or doing vigorous exercise at the current moment would likely impact their sleep later that night. ShutEye’s display appeared on the phone's lockscreen as well as its live wallpaper when the phone was unlocked. Icons for the phone's other applications—for example, “Gmail,” “Camera” or “Settings”—could sit on top of ShutEye’s wallpaper display.
ShutEye’s display used a timeline metaphor with colored horizontal bars that corresponded to activities that could impact sleep. Thin bars represented times when the activity was not recommended, while thick bars indicated that the activity was either unlikely to negatively affect sleep (e.g., having a cup of coffee) or likely to improve sleep (e.g., relaxing or exercising). The vertical bar indicated the current time on the timeline. The intersection of the activity’s bar with the vertical bar showed the current recommendation—if the activity’s bar was thin, the activity was not recommended; if it was thick, it was probably okay.
ShutEye was evaluated in a 4-week field study with 11 participants who were recruited from the general population.
ShutEye's Glanceable Display
Colored horizontal bars in ShutEye's display correspond to activities that could impact sleep. Thin bars represent times when the activity is not recommended, while thick bars indicate that the activity is either unlikely to negatively affect sleep (e.g., having a cup of coffee) or likely to improve sleep (e.g., relaxing or exercising). The white vertical bar indicates the current time. The intersection of the activity’s bar with the vertical bar shows the current recommendation—if the activity’s bar is thin, the activity is not recommended; if it’s thick, it’s probably okay.
