After gathering additional field experience, the following ideas emerged:
Context: Falls occur often by the bedside in the bedroom and in bathroom. Both of these are private, space constrained areas with suboptimal visibility. Makes it hard to gather good training data for fall detection.
Possible solutions:
Short time window (10-15 second) time series that capture a sequence of pose detection keypoints and feed them to an anomaly detection model for acute problems such as falls.
Longer time window (24 hour) that compares time series from the most recent 24 hour and the historical 24 hour data distribution to detect anomalies and predict potential upcoming complications that are signaled by change in daily routines.
Experiment with even longer term time windows to learn about weekly, monthly, seasonal, annual cycles that might relate to health and wellbeing.
This issue has been automatically marked as stale because it has not had recent activity. It will be closed if no further activity occurs. Thank you for your contributions.
Most people and especially elderly have a recurring daily pattern of movement around their home.
An AI sequence model could learn to predict movements and detect anomalies. Examples:
