Abstract: The invention comprises a system that monitors heart activity through embedded ECG sensors in a desk, and desk-related amenities such as a chair, a computer keyboard, a mouse, and a floor mat. The invention also comprises pressure sensors for monitoring a user's presence at the desk. Signals measured from the ECG or pressure sensors are transmitted (in a wired, or wireless fashion) to a computer processing device which applies algorithms to refine the collected signals, and passively estimate the user's ECG.

Abstract: The invention provides users with suggestions on other users that they should meet, who they would not have been likely to meet without such a suggestion. The invention optimizes the a-priori likelihood of positive interactions between such users by suggesting meeting locations, times, and topics of conversation. The invention optimizes the real-time interaction between users using sensors that capture one or more modalities of data and provides real-time feedback to users via one or more digital devices. The invention optimizes user's future interactions by providing retrospective analyses of prior interactions, and accompanying recommendations for how to optimize ongoing or future interactions.
