Face Tracking

Face Tracking (FT) / Face Reading is used when referring to all information technologies used for the identification and analysis of emotions using static and dynamic images of human facial expressions. It includes a set of information technologies from the area referred to as “affective computing”, which deals with hardware and software for the automatic recognition of human emotional expressions through computer detection and analysis techniques.

These technologies are usually based on two facial expressions’ recognition systems:

  • FACS (Facial Action Coding System) – A system for coding facial movements
  • FAP (Facial Animation Parameters) – part of the MPEG-4 standard specification defining the description of the human face movements based on the 84-point geometric model.

Application similar to EMG:

  • Visualization (TV, radio, press, printed advertising, packaging etc.)
  • Sound material (jingle, background music, sound effects, songs)
  • The scents of dishes, spaces, perfumes, etc.,
  • The taste of food
