jsPsych is a JavaScript framework for creating behavioral experiments that run in a web browser.
Plugin Description
The canvas-button-response plugin allows for an experimenter to draw a stimulus on an HTML canvas element, allowing for dynamic, parametrically-defined graphics, and for controlling the position of multiple graphical elements on the canvas (such as shapes, texts, or images). This stimulus can be displayed until a response is given, or for a specified amount of time. The trial may also be ended automatically if the partipicant fails to respond in a certain time. One or more button choices will be displayed under the canvas, which can be styled with HTML formatting.
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.
