The concept of micro-augmentations is a new augmented reality tool and methodology. It can provide novel ways to interact with cultural content (including learning content). The purpose of the present work was to study the effects of micro-augmentations on human brain waves and to find possible relations between micro-augmentations and personality characteristics, such as cognitive styles. The gender of the participants and the emotions they experienced during their exposure to micro-augmented content was also recorded and analyzed. An EEG headset was used to measure participant's brainwave activity and waves measured were theta, high beta, low gamma and high gamma, as well as participants' attention levels. After the experiments, participants answered questionnaire recording the emotions they experienced and their personality characteristics. The results of the study showed that micro-augmentations increased the brain activity and affected peoples' certain emotions.
