Performance of our proposed sleep faster program. (a) Statistical distribution of deviation of sleep onset latency (SOL) estimation between Earable and PSG. (b) The structure of stimulation audio/voice used in our stimulation protocols. (c) SOL results of the 2-day nap protocol using PSG. Stimulation is used on Day 2 and not used on Day 1. (d) SOL results of a 3-day nap protocol using PSG. Stimulation is used on Days 2, 3 and not used on Day 1. (e) SOL results of the 4-day nap protocol using PSG. Stimulation is used on Days 3, 4 and not used on Days 1, 2. (f) Example of Probability of Being Asleep (PoAs) of a user at the beginning of 3 sleep sessions Day 1, 2, and 3. Closed-loop stimulation is used on Days 2 and 3. The solid arrows indicate the SOL measured by sleep staging. The dashed arrows indicate the occurrence of content switching (CW) during the closed-loop stimulation on Days 2 and 3. (g) SOL results of a 2-day nap protocol using Earable. Stimulation is used on Day 2 and not used on Day 1. (h) SOL results of 3-day full night sleep protocol using Earable. Stimulation is used on Days 2 and 3 and not used on Day 1.
