psychopy.iohub- ioHub event monitoring framework¶
ioHub monitors for device events in parallel with the PsychoPy® experiment execution by running in a separate process than the main PsychoPy® script. This means, for instance, that keyboard and mouse event timing is not quantized by the rate at which the window.flip() method is called.
ioHub reports device events to the PsychoPy® experiment runtime as they occur. Optionally, events can be saved to a HDF5 file.
All iohub events are timestamped using the PsychoPy® global time base (psychopy.core.getTime()). Events can be accessed as a device independent event stream, or from a specific device of interest.
A comprehensive set of examples that each use at least one of the iohub devices is available in the psychopy/demos/coder/iohub folder.
