Abdominal breathing restrictor for mental tension enhancement


This paper presents an apparatus that intentionally makes a person sensitive to mental tension by controlling his/her breathing pattern. The apparatus is called abdominal breathing restrictor (ABR). ABR realizes mental control function based on the knowledge of the relationship between breathing patterns and mental condition. Abdominal breathing is well known to relax the mental state of a person. Conversely, costal breathing results in mental tension. The ABR impedes abdominal breathing and compels one into costal breathing, leading him/her into mental tension. The experimental results described in this paper demonstrate that ABR successfully controlled the mental state of a subject. ABRs can be used to control mental condition of the audience in movie theaters.
