EHA is an idea to support chronically ill person's independent living. It is a technology to notify the relatives and caregivers of chronically ill person of an emergency situation, even if the patient is not able to call them or is not aware of the danger.

In addition to providing the call button option available in similar solutions, EHA acts based on patient's vital signals pattern and sends alarm to caregivers in case of observing dangerous anomalies in these signals. The system also collects continues data records of health signals in an operation center and use them as background information to provide caregivers guidance if required.
