This study presents PsyPad, an open-source iPad application for creating and running visual psychophysics experiments. Researchers can easily configure experiments and collect data without coding, making psychophysical testing more accessible.
Area of Science:
- Psychology
- Computer Science
- Neuroscience
Background:
- Conducting visual psychophysics experiments traditionally requires specialized software and coding expertise.
- Mobile devices offer potential for accessible and portable experimental platforms.
Purpose of the Study:
- To introduce PsyPad, a customizable, open-source platform for visual psychophysics experiments on iPads.
- To enable researchers to configure and conduct experiments without requiring iPad-specific coding.
Main Methods:
- PsyPad utilizes an image library for stimuli, configured offline.
- Experiments employ customizable staircase or method of constant stimuli procedures.
- On-screen buttons and response matching are configurable via image file names.
Main Results:
- PsyPad allows for the creation and execution of visual psychophysics experiments directly on iPads.
- Data logging and secure server upload are integrated features.
- The platform is open-source, allowing for custom server-side implementations.
Conclusions:
- PsyPad provides a user-friendly, code-free solution for visual psychophysics research on iPads.
- The open-source nature promotes accessibility and customization in experimental design.
- This platform can streamline data collection and analysis in psychophysical studies.
