As suggested in the section on tactile output hardware, tactile output can take a number of forms. Current electronic games tend to favor causing players' joypads to rumble or shake.These often underline activities in the game at a low level, for example rumbling while a player controlled entity is near an explosion. Another popular form of tactile output is force feedback through a steering wheel while taking sharp turns in racing games, or similar feedback to reflect difficult turning or being struck in flight combat simulators. Gun kick is another popular form of tactile feedback, adding a sense of haptic realism to games such as Time Crisis [Namco, 1996].
Other forms of tactile feedback have become available that are less directly tied to player controlled game entities or actions, such as the vibratory actions of the Rez Trance Vibrator, which provides tactile feedback that mirrors the game's background music.
