This patch captures the video data coming from a given video input device and returns it as an image. The captured images will have the size of the video input device's native resolution. Note that depending on the circumstances, you might not be able to have more than one instance of this patch per video input device. more...

This patch analyzes the audio data coming from a given source of an audio input device and computes its frequency spectrum along with its peak value. more...

This patch returns the current state of the tablet pointing device. The pen position is expressed in units in the Quartz Composer coordinates system. The pen tilt on the X and Y axes is normalized to the [-1.0,1.0] range and the pen pressure is normalized to the [0,1] range. Note that this patch does not read the tablet state directly but is dependent on the proper information being passed to the composition. This information may not always be available, depending on the environment in which Quartz Com... more...

This patch returns the current state of the mouse pointing device. The mouse position is expressed in units in the Quartz Composer coordinates system. Note that this patch does not read the mouse state directly but is dependent on the proper information being passed to the composition. This information may not always be available, depending on the environment in which Quartz Composer is running. more...

This patch returns the current state of a customizable list of keys of the keyboard device. Each observed key is represented by a boolean output set to True when the key is down and False otherwise. Because the keys are actually observed through the character they produce, key modifiers (like [Shift], [Control]...) matter: for example, 'Q' is considered different than 'q'. Note that this patch does not read the keyboard state directly but is dependent on the proper information being passed to the compo... more...

This patch returns the current state of a list of observed elements of a connected HID compliant USB input device. more...

This patch returns the current state of the Apple Remote. Note that even if the host computer is compatible with the Apple Remote, the remote might not necessarily be accessible. more...
