ABSTRACT
Predictive systems can determine where things are heading and can give fair warning, and, in some cases, automatically change course to avoid danger. Logically, the value of a predictive system depends on its accuracy. Avoiding false positives and, perhaps more importantly, avoiding false negatives is key. Products should give forewarning so users have a chance to prevent or avoid hazardous situations before they can occur. Even with the aid of predictive systems, humans might be too slow or unreliable to avoid certain hazards effectively, leading some designers to consider automation as a means to compensate for our shortcomings. Airline warning systems issue a ground proximity warning, “Woop Woop” Terrain Terrain,” if the current fight path will lead to a crash. Automobile collision avoidance systems can detect hazards and automatically apply the brakes to avoid a collision.
