Mood Matrix

Unreleased

The Mood Matrix is a device used by lawyer Athena Cykes in Phoenix Wright: Ace Attorney: Dual Destinies that is hung around her neck as a necklace. Cykes uses it to examine the emotions of witnesses while they are giving their testimonies.

Function
The Mood Matrix 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 Mood Matrix.

While the Mood Matrix is not being used, it takes on the appearance of one of four faces to reflect Cykes's mood.

Other languages
The device is called the "heart scope" (ココ口スコ‐プ, "kokoro sukōpu") in the Japanese version of the game.
