Riponda

Riponda is a compact, configurable response pad developed by Cedrus for research applications requiring precise and reliable reaction time measurement. With over 30 years of design experience, Riponda offers millisecond-level timing accuracy, customizable key layouts, and broad compatibility with stimulus presentation software. It is well suited for cognitive psychology, neuroscience, and other experimental paradigms where participant response timing is critical.

Riponda is the sixth-generation response pad from Cedrus and has been built from the ground up with a modern interface and integrated support for key software packages. Whether used in Keyboard mode for wide compatibility or with dedicated software libraries for jitter-free performance, Riponda adapts to both current and evolving experimental needs.

System Features

• Reliable and consistent timing
  Custom-built electronics and firmware provide response times of less than 500 microseconds when used with compatible software.
• Software flexibility
  Riponda works natively with SuperLab, Inquisit, E-Prime, Presentation, and others. For custom workflows, Python and C++ libraries are available. It can also be used in Keyboard mode with any software.
• Four model options
  Available in Model C, L, S, and E configurations to suit various experimental designs, including spatial orientation tasks, Likert scales, or ergonomic requirements.
• Voice and light sensor inputs
  Connect an optional microphone for vocal response onset detection or a light sensor to mark stimulus onset visually.
• Digital event marking
  Compatible with Cedrus m-pod and StimTracker for accurate TTL event output to EEG, NIRS, and eye-tracking systems.
• USB-C connection with switchable modes
  Operates in Keyboard (HID) or Standard (Serial) mode. Select data formats and baud rates via DIP switches.
• Upgradeable firmware
  Built on Cedrus’ XID 2.0 platform for long-term expandability and precise control.
