Final answer:
In an IoT healthcare monitoring system, sending an alert to the patient's device for acknowledgment signifies an interactive notification within a real-time monitoring framework.
Step-by-step explanation:
In an IoT healthcare monitoring system, when the system sends an alert to the patient's device which he/she must acknowledge, it exemplifies an interactive notification. This type of system employs sensors and devices that collect data about the patient's health status, which is then analyzed. Upon detecting any anomalies or concerning patterns, the system generates an alert to notify the patient. The requirement for the patient to acknowledge the alert ensures that the patient has received and recognized the potential issue, triggering appropriate follow-up actions. It demonstrates the real-time monitoring and responsiveness capabilities integral to IoT-based healthcare solutions.
