Sleep induction device and method for inducting change in sleep state

Abstract

The invention relates to a sleep induction device for inducing changes during a sleep session of a user, wherein the sleep induction device comprises at least one sensor for detecting a physiologicalcharacteristic of the user, a stimulator which is configured to provide successive stimuli to the user to anticipate on the detected physiological characteristic, which successive stimuli define a guidance path, and which guidance path is to be followed by the user to induce a change during the sleep session of the user, a memory which is arranged to store values of detected physiological characteristics, and provided stimuli during the sleep session, and a processing unit including a control programme which is programmed to determine a current sleep state of the user, which current sleep state is based on at least one detected physiological characteristic measured by the at least one sensor and which control programme is programmed to generate an initial guidance path to induce a change from the determined current sleep state to another sleep state, wherein the control programme comprises a tracking programme which is programmed to track during the sleep session a deviation of a detected physiological characteristic from an expected physiological characteristic which expected physiological characteristic is based on the initially provided guidance path and a tailoring programme which is programmed to tailor the initially provided guidance path during the sleep session of the user to an updated guidance path when the tracked deviation exceeds a pre-determined margin.

Description

technical field [0001] The present invention relates to a sleep inducing device for inducing changes during a user's sleep period and a method for inducing a user's sleep state change during a user's sleep period. Background technique [0002] US7,041,049 discloses a method and device for obtaining efficient sleep and using sleep time more effectively. By monitoring the physiological characteristics of selected sleepers, it is possible to determine which sleep stage the sleeper is in, when the sleeper transitions to a different sleep stage, and whether the sleeper follows the sleep guidance system. Sleep guidance systems provide sensory stimuli to induce changes in sleep. Before the device can be used effectively, it must be calibrated to determine a sleeper's physiological responses to sensory stimuli during sleep periods and sleep pattern responses. Beginning with this calibration step, a personalized sleeper profile is built. The profile includes stimulus settings to i...
