No wonder why Procter & Gamble used Emotient's software to test three fragrances for Tide detergent. According to Emotient, the system is so precise that it can detect single-frame expressions of emotion. These brief flashes of emotions reveal quite a bit about a person’s beliefs and their propensity to act or buy, according to the company. Emotient’s proprietary algorithms make it possible to discern the most subtle expression or changes in expression and translate that into a defined emotional reaction. With a camera-enabled device or external webcam, the system can quickly process facial detection and automated expression analysis in real-time, or, for non time-sensitive requirements, it can scan images and videos in batch mode to deliver in-depth analysis of single-subject and multiple-subject videos.
