Abstract: Systems and methods for implementing an emotional human-machine interface (HMI). A vehicle may comprise a display for presenting an emotional HMI. The emotional HMI may be determined by determining a first occupant of the vehicle, collecting first biometric data for the first occupant using at least the one or more sensors, determining, using an emotion engine of the vehicle, a first emotional state of the first occupant, determining a second occupant of the vehicle, determining, using the emotion engine of the vehicle, a second emotional state of the second occupant, and determining a graphical interface comprising at least a first color scheme based at least in part on the first emotional state and a second color scheme based at least in part on the second emotional state.
