The document describes how WebRTC technology can be used to enable real-time video calls between doctors and patients. It outlines a solution built using Twilio, IBM Watson, and other Bluemix services. The solution allows a patient to initiate a video call with their doctor, with the patient's audio being transcribed in real-time using Watson Speech to Text. The transcription is stored and analyzed for personality insights. It is also sent back to the doctor. The solution was built in 3 days, but faced some challenges around ordering of calls, browser compatibility, scaling websockets, and dropping connections to Watson.
