Think about data extraction when you program your experiment in Medialab.
How you program your experiment in Medialab impacts your data extraction procedure significantly. Below is an example of data extraction for a poorly designed experiment in MediaLab & DirectRT. The PDF has nine pages of instructions to extract the physiological data of a single participant and on average it took the research team about 20 to 30 minutes to extract this data for each participant. The most poorly thought out feature of the MediaLab program is that it sent event markers/ttl pulses for irrelevant data that was not going to be analyzed or extracted. The effect of this is visualized on pages five and seven.
