Collecting subject responses with standard PC keyboards is beridden with many problems. The keyboard response timing accuracy is questionable at best, the keys are small which makes entry error prone and the layout is maximally unergonomical for experimental response acquisition.
Cedrus brand new Riponda series response pads addresses all of the above issues optimally, and as Cedrus' 6th generation of response pads, the also build on the long history of the successful RB response pads.
The Riponda series response pads are microprocessor controlled and contain own timing logic to guarantee millisecond response time accuracy under all circumstances. In addition to the market leading features of their predecessors, the RB pads they also now incorporate a voice key, thus adding in the feature set of the now discontinued Cedrus SV-1 Voice Key system.
The four available key pads with their layouts in star shape, line,shape, box shape and also ergonomically curved shape offer you all the freedom to implement exactly the response terminal you need for your experiments. The ergonomic key sizes, easy to trigger button caps and the possibility to use (included) color key caps directly support your experimental paradigm.
If your task is a spatial one, chose a spatial pad orientation. And if you need accurate bimanual responses, choose a slanted (ergonomically curved) pad design. It is that simple, it should be ...

Riponda Response Pads
- Why Use a Response Pad? - There are a number of reasons for using a response pad instead of a keyboard, mainly:
* Resolution
Cedrus' response pads offer 1 millisecond reaction time resolution. By contrast, the Mac keyboard (pre iMac) offers 4 milliseconds or (iMacs and later) 10-12 milliseconds. The PC's resolution ranges between 20 and 35 milliseconds for PS2 keyboards and 10-12 milliseconds for USB keyboards.
* Simplicity
A typical keyboard has 105 keys. This can be confusing to participants and might render the reaction time data meaningless if they spend a lot of time looking for the correct key. This factor is particularly important for certain groups such as children, participants with Alzheimer's Disease, and novice computer users.
* Customizable
Every response pad includes, free, color and clear key tops. This makes it even easier for participants to follow instructions (e.g. press green key if correct or red if incorrect) and helps improve further the quality of the collected reaction times.
RB Series Response Pad Featuresand Benefits:
