We should remember to evaluate interventions based on the cost and rate of false positive/negatives, vs. the benefit of true positive/negatives.<p>In this case, the pertinent benefit to weigh against is the benefit of fall detection, particularly for elderly people, but also for active folks e.g. falling while cycling.<p>Obviously we’d rather not make false emergency calls, all else being equal. But it could be worth it on its face, we need to analyze the benefits to know.
