Welcome to PsyPad!

PsyPad is an open source platform for facilitating visual psychophysics experiments on an iPad. PsyPad was created by Prof Allison McKendrick and Prof Andrew Turpin to facilitate their vision research and to share with the world. We also appreciate acknowledgement for the same, so if you use PsyPad for your research, please cite: Turpin A, Lawson D, McKendrick AM. “PsyPad: A platform for visual psychophysics on the iPad”. Journal of Vision, 2014 Mar 11;14(3):16. doi: 10.1167/14.3.16.

The accompanying iPad app (available in the App Store) can run staircase or MOCS procedures using a library of images that you create to determine visual stimuli. Your image library can be built using a tool of your choice (eg R, MATLAB, etc), and uploaded through this server. Alternately you can download image sets that have been created by other users, and share your own, as part of the Public Gallery on the server, or just use the Demo Mode. The server can also be used to configure tests, and process logfiles from tests that have been conducted on the iPad. If you want help creating your images, contact Andrew Turpin.

You can create an account at the PsyPad Server. Note that non-academic affiliations are not encouraged, and may result in your account being deleted.
