What are the different types of data sets?
Discussed are audio and video recordings, interviews and observations, experiments in labs, eye tracking and medical screening (MRI/EEC/ECG....)
Audio and video recordings as dataset
Audio and video recordings are regularly used in academic research. Sometimes these recordings can be made anonymous by blurring faces, or just filming hands, but this depends strongly on the purpose of the study.
Interviews, observations, and experiments in labs
Researchers often make reports of interviews and observations. In some studies, experiments with test subjects are done in labs. Sometimes special personal data is measured, for instance taking someone's blood pressure to see if they are experiencing any stress.
Some scientific studies use eye-tracking to track eye movements. One example is a study on the way people look at websites.
Medical screening (MRI/EEG/ECG...)
A number of scientific studies make use of medical screening such as MRI, EEG and ECG. The results constitute special personal data, to which the following guidelines apply.
If wearables, such as a Fitbit, are used for an academic study, the following guidelines apply.
