ABSTRACT
Games are interactive computer simulations, so the human player(s) need some way of providing inputs to the game. All sorts of human interface devices (HID) exist for gaming, including joysticks, joypads, keyboards and mice, track balls, the Wii remote, and specialized input devices like steering wheels, fi shing rods, dance pads, and even electric guitars. In this chapter, we’ll investigate how game engines typically read, process, and utilize the inputs from human interface devices. We’ll also have a look at how outputs from these devices provide feedback to the human player.
