PVRT - Peripheral Visual Recognition Task for Python
====================================================
by Simon Schwab

PVRT (Peripheral visual recognition task) is opensource Python software
based on the PsychoPy framework to conduct visual experiments, in which
first a visual target is presented in the center and then in the periphery
of the visual field.

- Presentation of visual stimuli using OpenGL
- Recording of subject responses through parallel port using the PortIO library
- Eye and head calibration according to the requirements of the eye tracker
- Notification of the eye tracker (TTL signals)
- Well structured data files for further processing

A. Requirements
===============

- PsychoPy v1.60 or highter (http://www.psychopy.org/)
- Tk/Tkinter a Graphical User Interface Framework
- PortIO (http://portio.inrim.it/)
- OpenGL

B. Installation instruction for Ubuntu
======================================

a) Install PsychoPy requirements
  $ sudo apt-get install python-wxgtk2.8 python-numpy python-scipy python-pyglet

b) $ sudo apt-get install psychopy

c) Install Tkinter
   $ sudo apt-get install python-tk #if not already installed

d) PortIO
   Download PortIO from http://portio.inrim.it/ and unpack it
   $ tar xvf portio-0.4.tar.gz
   $ cd portio-0.4/
   But first, before we build it, you need python-dev
   $ sudo apt-get install python-dev #if not already installed
   Build and install PortIO
   $ sudo python setup.py install

f) $ sudo apt-get install python-opengl #if not already installed

g) Finally, install and run pvrtask
   Unpack the pvrtask package
   cd pvrtask/src
   $ sudo python pvrtask.py
