New facial expression technology for human behaviour analysis

Barcelona, Spain

Bioobserver automatically detects and annotates a person’s facial expressions and micro-expressions, as well as the direction of the gaze and head orientation.

Herta is launching the company's new video analysis solution, Bioobserver,  a sophisticated software aimed at marking a significant change in the study of human behaviour and facial expression analysis.

Based on advanced artificial intelligence techniques, Bioobserver automatically detects and annotates a person’s facial expressions and micro-expressions, as well as the direction of the gaze and head orientation, in order to monitor behavioural metrics such as affective states or the individual’s level of attention.

The platform also allows for the configuration of automatic rules and annotations of events to extract key frames of the video that are considered of interest.

With Bioobserver subtle micro-expressions such as “frowning”, “blinking” or “raising eyebrows” can be detected, according to the Facial Action Coding System by Paul Ekman. The tool offers the possibility to work at a very low level. Then, the combination of some micro-expressions may form a higher-level prototypic facial emotion (such as joy, anger, sadness, fear, surprise…) which can be configured in the software as well.

This new solution has been co-created together with key end-customers from the law enforcement sector, resulting on a user-friendly, intuitive and time-saving tool that any interviewer would love. The solution is being offered as an SaaS model and will allow the customer the opportunity to process hours of video, extremely fast and at a favourable price point.
