Universal Serial Bus HID Usage Tables 15right, and left.KeyboardKeypadMulti-axis ControllerCA – The primary computer input device. A Keyboard minimally consists of103 buttons as defined by the Boot Keyboard definition. For details, seeAppendix A of the HID Specification.CA – Any keyboard configuration that does not meet the minimumrequirements of the Boot Keyboard. Keypad often refers to a supplementarycalculator-style keyboard.CA - An input device used to orient eyepoints and or objects in 3 dimensionalspace. A Multi-axis Controller typically consists of six, variable axes (X, Y,Z, Rx, Ry and Rz) and is used by CAD/digital content creation applicationsfor model manipulation and visualization in 3D space. The device mayincorporate zero or more buttons.4.2 Axis UsagesFor X, Y, Z, Rx, Ry, and Rz, the declaration of Units is optional. If Units is None or not declared, thesevalues should be considered as dimensionless.XYZRxRyRzDV – A linear translation in the X direction. Report values should increase asthe control’s position is moved from left to right.DV – A linear translation in the Y direction. Report values should increase asthe control’s position is moved from far to near.DV – A linear translation in the Z direction. Report values should increase asthe control’s position is moved from high to low (Z).DV – A rotation about the X axis. Angular position report values follow therighthand rule.DV – A rotation about the Y axis. Angular position report values follow therighthand rule.DV – A rotation about the Z axis. Angular position report values follow therighthand rule.4.3 Miscellaneous ControlsSliderDialWheelHat SwitchDV – A linear control for generating a variable value, normally in the form ofa thumb slide in a slot. Report values should increase as controls are movedfrom near to far.DV – A rotary control for generating a variable value, normally in the form ofa knob spun by the index finger and thumb. Report values should increase ascontrols are spun clockwise. This usage does not follow the HID orientationconventions.DV – A rotary control for generating a variable value, normally rolled, unlikea dial. Report values should increase as controls are rolled forward, awayfrom the user. This usage does not follow the HID orientation conventions.DV – A specialized mechanical configuration of switches generating avariable value with a null state. The switches are arranged around aspringloaded knob. When the knob is tilted in the direction of a switch, itscontacts are closed. A typical example is four switches that are capable ofgenerating information about four possible directions in which the knob canVersion 1.1 April 8, 1999
