The Idea

We specialize in detecting social signals and making them meaningful to our users.

We develop software that analyzes video and audio recordings of two or more interacting people. We detect non-verbal signals such as posture, body movements, facial expressions, intonation and rate of speech. These signals are automatically quantified and interpreted to obtain relevant information and actionable feedback on how one’s behavior shapes the quality of interaction in a diverse range of fields and situations – including but not limited to negotiations, presentations, and healthcare consultations.

The first use case we are developing consists of online negotiation training sessions where two or more users interact via online video conferencing. These sessions are automatically analyzed in order to determine the quality of the interaction over time and to identify cooperative or perturbing behavior. This information helps our users recognize their strengths and weaknesses and develop strategies to improve their nonverbal communication skills. We use this information to continually and adaptively generate personalized training regimens for our users. We can provide this service either standalone or as part of a broader talent development program.
