System and kit for stress and relaxation management
First Claim
1. A system for stress and relaxation management, comprising:
- at least one cardiac activity sensor for measuring a heart rate variability (HRV) signal of a user,at least one respiration sensor for measuring a respiratory signal the user (109),a user interaction device comprising an input unit for receiving user specific data and an output unit for providing information output to the user, anda processor adapted to assess the stress level of the user by determining a user related stress index, the user related stress index being determined based on a first and a second HRV parameter value associated with a first posture and a second posture, respectively, where a difference between the HRV parameter values is used as an indicator to determine the user related stress index, the stress index being used as an input in triggering commands instructing the output unit to provide the user with a message indicating the stress level of the user,the processor further being adapted to monitor the user during a relaxation exercise by means of determining a relaxation index based on the measured HRV and respiratory signals by means of calculating an index of coherence between the HRV signal and the respiratory signal during the relaxation exercise, the relaxation index being continuously adapted to the incoming measured signals and based thereon the processor instructs the output unit to provide the user with biofeedback and support messages,the processor further being adapted to use the user specific data as an input in generating a first set of rules defining an improvement plan for self-management of stress and relaxation, said first set of rules being adapted to trigger commands instructing the output unit to provide the user with motivation related messages.

Abstract
This invention relates to a system and a kit for stress and relaxation management. A cardiac activity sensor (101) is used for measuring the heart rate variability (HRV) signal of the user and a respiration sensor (102) for measuring the respiratory signal of the user. The system contains a user interaction device (103) having an input unit (104) for receiving user specific data and an output unit for providing information output to the user. A processor (106) is used to assess the stress level of the user by determining a user related stress index. The processor is also used to monitor the user during a relaxation exercise by means of determining a relaxation index based on the measured HRV and respiratory signals, the relaxation index being continuously adapted to the incoming measured signals and based thereon the processor instructs the output unit to provide the user with biofeedback and support messages. Finally, the processor uses the user specific data as an input in generating a first set of rules defining an improvement plan for self-management of stress and relaxation. The first set of rules is adapted to trigger commands instructing the output unit to provide the user with motivation related messages. Also, at least a portion of said user specific data is further used to define a second set of rules indicating the user'"'"'s personal goals.
