SimplePhy

SimplePhy facilitates online psychophysical perception experiments by presenting stimuli and recording behavioral responses together with display and timing metrics.

Key Features:

• Behavioral response recording: Logs participant responses via mouse clicks and button presses.
• Viewing-distance estimation: Estimates the viewing distance between participants and their monitors.
• Display metrics: Records screen sizes and related display information.
• Timing metrics: Tracks experimental trial timings.
• Stimulus presentation configuration: Accepts uploaded stimuli and predefined experiment settings for presentation.
• Data collection and management: Backend processes handle data collection and management.

Scientific Applications:

• Psychophysics experiments: Measurement of perceptual responses in psychophysical and perception studies.
• Remote behavioral research: Collection of behavioral and display-related data from online participants.
• Display-dependent studies: Experiments requiring estimation of viewing distance and screen characteristics.

Methodology:

Researchers select predefined experiment settings and upload stimuli; the system presents stimuli, records mouse clicks and button presses, estimates viewing distance, records screen sizes, tracks trial timings, and the backend processes handle data collection and management.
