Wake IQ: Using a smartphone to reduce sleep inertia

This paper presents Wake IQ, a smartphone program to reduce sleep inertia. Wake IQ aims at waking its user with proper timing so as to reduce or eliminate sleep inertia and increase overall alertness, while maintaining a convenience conducive to everyday use. It is constructed based on machine learning techniques, phone accelerometer data sampled during slumber, and user alertness test scores. Tests of the system have demonstrated a gradually increasing average response speed to reaction time tests over a period of a number of weeks, indicative of a trend towards reduced sleep inertia arising from use of the smartphone application.
