The AEON app helps users in practicing a mindfulness technique that requires individuals not to react in response to their thoughts, but to be aware of them and observe them while they are going away (distancing from thoughts). The effectiveness of the AEON app was tested in a thorough lab study, published by the International Journal of Human-Computer Studies (Elsevier), see http://hcilab.uniud.it/publications/354.html For more information, visit also the AEON page: http://hcilab.uniud.it/aeon
