Or maybe the system could be designed in such a way that requires the lifeguard to stay attentive, such as requiring the lifeguard to input the current headcount. I too worked as a lifeguard and I think only a really bad implementation can have a counter-productive effect. Spontaneously, I can think of sunglasses with AR-overlay and a feedback loop: * mark all people in field of view, color coded * let lifeguard acknowledge/ignore problems * allow for "problem"-handover to next post (e.g. if busy or if it is a swimmer in a current) What definitely does not help is to have lifeguards behind monitors because they'd miss out on 99% of the real daily "action": dealing with littering, violence, ordinance violations, answering questions, pointing new arrivals towards safe zones....
