The new calls have several advantages: - the polling is performed and timestamped asynchronously with the main thread so that times relate to when the key was pressed, not when the call was made - the polling is direct to the USB HID library in C, which is faster than waiting for the operating system to poll and interpret those same packets - we also detect the KeyUp events and therefore provide the option of returning keypress duration - on Linux and Mac you can also distinguish between different keyboard devices (see :func:`getKeyboards`) This library makes use, where possible of the same low-level asynchronous hardware polling as in `Psychtoolbox `_.

Psychtoolbox versus event.getKeys - On 64 bits Python3 installations it provides access to the `Psychtoolbox kbQueue `_ series of functions using the same compiled C code (available in python-psychtoolbox lib). #!/usr/bin/env python # -*- coding: utf-8 -*- '''To handle input from keyboard (supersedes event.getKeys) The Keyboard class was new in PsychoPy 3.1 and replaces the older `event.getKeys()` calls.
