NoldusHub: A novel measurement tool for behavioral research in the lab

The NoldusHub product is a behavioral science tool with aim that the user can focus on the experiment: not the technology. When inviting multiple participants, each participant is given sensors such as eye tracker and wearable devices, It is challenging for a testleader to ensure that all sensors are charged and correctly attached, cameras pointing the right direction etc. Because of too many failed experiment sessions, existing behavioral science today restricts itself to single session, single participant and scientists avoid the so called emerging measures that modern technology provides.

One server in a LAN acquires, synchronizes and stores the collected data. Local Client participant PC's equipped with wearable devices, eye tracker, screen capture, webcam generate data. The test leader can check the correct working of all sensor devices per participant from a local tablet. Once all is ready, a simple "Start Recording"" starts all relevant stimuli and synchronizes all received data. The testleader is notified of failing datastreams so these can be given attention as and when they happen - avoiding surprises after the event. Annotation of worthwhile events can be done by assistant testleaders during Acquisition. Replay of crew of single participant is available immediately after the test. The system currently works with 3 commercial eye trackers of different vendors and wearable psychophysiological devices from Shimmer PLC and camera/webcam. Internal algorithms calculate HeartRate HeartRateVariability, Tonic- and phasic response to ElectroDermal Activity and emotions and cognitive load are recognized from the camera view, resp. instantaneous pupil diameter. All this in sync with screen capture of the stimulus and facial video of each participant.
