These can be used as pointing devices, but are generally used in ways that don't involve pointing to a location in space, such as the control of a camera angle while in 3D applications . These kinds of devices are typically used in virtual reality systems (CAVEs), where input that registers six degrees of freedom is required . </P> <P> Input devices, such as buttons and joysticks, can be combined on a single physical device that could be thought of as a composite device . Many gaming devices have controllers like this . Technically mice are composite devices, as they both track movement and provide buttons for clicking, but composite devices are generally considered to have more than two different forms of input . </P> <P> Examples of types of composite devices include: </P>
