Welcome to the ExpLib homepage!

ExpLib is a code library and accompanying project written in Microsoft Visual C++ and using DirectX that allows for easy experiment generation and execution with good timing under the Windows environment.

Why should I use ExpLib?

• ExpLib is easy to use. Much easier than you may think. Yes, you need to know a little C++, but people with almost no programming experience have created fairly complicated experiments very quickly.  Just follow the examples...
• Compared to other similar programs ExpLib is inexpensive, heck, it's free!
• We believe ExpLib is the most versatile experiment generation program.  Not only do we provide you with vast functionality, but you have all the power of C++ behind your programs.
• ExpLib allows you to easily use Windows BMP files and Wav files as stimuli, so you can basically display anything.
• But, ExpLib also allows the display of stimuli that change over time. For example, you can create stimuli involving bouncing balls, changing colors, increasing volume. Almost anything you can think of.
• ExpLib allows stimuli to change over time based on user input from the keyboard, mouse, or up to two joysticks.  All of the input devices are treated in the same way, so they are easy to implement. 
• If you have a large number of stimuli that you don't want to create a priori, just create a stimulus class and let ExpLib do all the work for you. 
• ExpLib runs in Windows, so no more messing around with DOS.
• ExpLib gives you excellent control over timing of stimulus presentation and user input.
• ExpLib can also output when stimuli were actually presented, so you can make sure you are getting the timing you want.
• ExpLib allows you create complicated designs easily using very flexible branching, including probabilistic branching.
• ExpLib gives you control over the output of your experiments.
