Mood Matrix

The 'Heart Scope is a device used by lawyer Kokone Kizuki in Gyakuten Saiban 5. She uses it to examine the emotions of witnesses while they are giving their testimonies.

Function
The Heart Scope uses a holographic screen that shows the emotions that a witness is experiencing while giving his or her testimony. There are four faces at each corner of the screen representing generic emotions: happy, angry, scared and surprised. The goal is to find contradictions between what the testimony should make the witness feel and what he or she actually feels. Finding these contradictions reduces noise in the Heart Scope.
