Comfortable environment for human by IRT based adaptive and intelligent interface

Abstract

The purpose of this paper is to make an adaptive and intelligent human interface with wearable hardware. At first, we are trying to estimate human's state in sleep using wearable sensor device, with less physical movement than daytime. Next, we are trying to control human biological rhythm using the method to estimate human sleep state. We are considering about most simple way to control human's sleep is to control awakening timing and sleep time. Proposed system can estimate human sleep quality and rhythms, and stimuli to user at the timing easy to wake. The system uses only pulse wave to estimate sleep quality because pulse wave can be measured easier than PSG.
