Good NEWS!
Our immo-RRB product portfolio has been updated!
New firmware, new program, new features but the same ease of use and the same price!
Take a look here!

The immo USB Reaction Response Box (immo-RRB) is the hardware you need if you want to measure reaction time with accuracy, without having to struggle with PC drivers.
Have you always made this type of measurement with a simple keyboard, but you are dissatisfied with accuracy and latency time? With RRB you can improve the performance and accuracy of your experiments.
The RRB doesn't need dedicated drivers, it is just a plug&play device!

You can connect the RRB directly to your pc with the provided USB cable, no extra hardware is required (i.e. USB to serial converter, which can introduce latency time and make your measure inaccurate).
It only takes five minutes to setup the RRB to suit your needs.
You can then simply connect your preferred input button to one of the two 3.5mm audio jack inputs and start measuring.
Simple PC software
With our user-friendly software interface you can easily configure the label response character to any key (default L and R), so you don't need any special modifications in your test programs.
You can also choose from three types of response: on press, on release or continuous.
Ultra low-latency keyboard replacement
If your test software can be used with a standard keyboard, then they will also work with the immo-RRB.
For each input you can choose the corresponding character to be sent to your pc.
The response type can also be configured to one of the following options:
  • on press: the character is sent when the button is pressed
  • on release: the character is sent when the button is pressed and released
  • on continuous: the character is continuously sent as long as the button is pressed

“At the University of Bern, Department of Developmental Psychology, the Reaction Response Box (RRB) are in use for experimental work concerning the cognitive development of children in the age range of 3 to 12 years. There, between 400 and 800 children a year are tested with computerized tasks measuring among other psychological constructs their attention and/or their working memory.”
