Falls are by definition unintentional, and sensor algorithms perform poorly when attempting to detect falls in the wild. Algorithm development has been reliant on simulation, i.e. asking actors to throw themselves intentionally to the ground.
Unfortunately, there are substantial and irreconcilable differences between a fake fall and a genuine one. In this paper, paper, the author discusses the differences between falls, ‘intentional falling’ and simulations, and the balance between simulation and reality in falls research.
