CB7 Response Knob

The CB7 allows the subject or experiment supervisor to make precise parameter adjustments to stimuli presented by the ViSaGe or other visual stimulus generators.

The high quality aluminium knob connects directly to your PC via a USB interface. It can be pressed like a button as well as rotated, and detects six actions:

• knob press
• knob release
• clockwise with knob released
• anticlockwise with knob released
• clockwise with knob pressed
• anticlockwise with knob pressed

We designed the CB7 as part of our Metropsis Macular Pigment Optical Density test, and it is now supported by the CRS Toolbox for MATLAB so that you can integrate it easily into your own experimental setup.
