jsPsych is a JavaScript framework for creating behavioral experiments that run in a web browser.
Plugin Description
The browser-check plugin measures and records a requested set of features from the participant's browser. An inclusion function is evaluated afterwards to determine if the participant's browser meets the requirements of the experiment. If they do, the trial ends and the experiment continues, otherwise the experiment will end immediately. If a minimum width and/or minimum height are desired, the plugin will optionally display a message to smaller browsers to give them an opportunity to make their border window larger.
To see the list of the features the plugin can check, see the documentation.
Examples
Several example experiments and plugin demonstrations are available in the /examples folder.
After you've downloaded the latest release, double-click on an example HTML file to run it in your web browser, and open it with a programming-friendly text editor to see how it works.
Documentation
Documentation for this plugin is available here.
