Abstract: Group coherence is facilitated in a group environment, such as a gaming, competitive, cooperative or collaborative environment. In one embodiment, a graphical representation of a scenario may be presented to a plurality of individuals. A physiological measure for each of the plurality of individuals may be sampled and used to track the individuals' heart rhythm patterns. A current group coherence level for the plurality of individuals may then be determined, where the group coherence level corresponds to a collective degree to which said plurality of heart rhythm patterns exhibit a sine waveform. In one embodiment, an appropriate modification to the scenario may be determined, where the modification is based on the current group coherence level. The updated graphical representation of the scenario may then be presented to the plurality of individuals.

Abstract: A portable electronic device monitors the pulse or electrocardiogram of a person by integrated, attachable or wireless sensors. The portable device evaluates this data in real-time to assess heart rate variability coherence, and provide feedback through a variety of sounds and an array of LEDs. The feedback may be in the form of a breathing indicator or pacer usable as a respiratory cycle training system to indicate to the subject when the next breath should be taken. Such feedback may be correlated to the level of coherency the subject achieves. A coherence indicator may be used to provide the subject with real-time information relating to the level of coherence achieved.

Abstract: A coherence value or category for an animal subject is calculated, and a corresponding coherence indication is provided to a human subject. In one embodiment, the beat-to-beat changes in the animal subject's heart rate is monitored, and used to calculate a coherence value, which may be representative of a coherence category. The coherence value may be determined by the power distribution of the heart rate variability data for the animal subject. In another embodiment, the degree of synchronization between an animal subject's coherence and an associated human subject's coherence may be determined and provided as feedback.

Abstract: Method and apparatus for determining the state of entrainment between biological systems which exhibit oscillatory behavior such as heart rhythms, respiration, blood pressure waves and low frequency brain waves based on a determination of heart rate variability (HRV) and an evaluation of the power spectrum thereof. Entrainment reflects a harmonious balance between the two branches of the autonomic nervous system within the body. This internal state of heightened physiological efficiency enhances health and promotes optimal performance. According to one embodiment a method is used to determine the entrainment level based on an entrainment parameter related to HRV. The method first determines the power distribution spectrum (PSD) and then calculates an entrainment parameter (EP), which is a measure of the power distribution in the HRV spectrum.

Abstract: Systems and methods for electrophysiological detection and measurement of intuition are disclosed. In one embodiment, one or more electrophysiological properties of one or more individuals are monitored and used as an indication of a future event. In one embodiment, the electrophysiological property may include heart rate variability, brain wave activity, respiration pattern, skin conductance level, etc. In another embodiment, a signal averaging technique is used to generate a waveform that may be used as an indicator of future events.

Abstract: Systems and methods for facilitating physiological coherence using respiratory training are disclosed. In one embodiment, an optimal respiratory cycle and/or RSA pattern is determined. A subject is then trained to adhere to this optimal respiratory level using one or more breath indicators. In another embodiment, the timing sequence of the breath indicators is optimized for a given subject's reaction time and/or atypical breathing events. In yet another embodiment, a subject's respiratory rhythms are used to detect their emotional state and corresponding feedback provided.

According to one embodiment a method is used to determine the entrainment level based on an entrainment parameter related to HRV. The method first determines the power distribution spectrum (PSD) and then calculates an entrainment parameter (EP), which is a measure of the power distribution in the HRV spectrum. High EP values occur when this power is concentrated within a relatively narrow range of frequencies, and lower values when the power is distributed over a broader range of frequencies.
