Line 1: A '''behavior-shaping constraint''', also sometimes referred to as a [['''forcing function~~]],~~''' or [[poka-yoke]], is a technique used in [[error-tolerant design]] to prevent the user from making common [[error]]s or mistakes. One example is the reverse lockout on the transmission of a moving [[automobile]]. Another example from [[interaction design]], although not strictly a forcing function, is how software programs usually give a visual indication of what selection has been made by highlighting it with [[reverse video]] to aid in preventing [[description error]]s, where an intended action is performed on an object that isn't the one intended. ==External links==
