A portable, closed-loop system of capture, analysis, and feedback uses a headset containing a small unobtrusive camera and a control computer that communicates wirelessly with a wireless network and/or remote platform. The headset may also contain user controls, an audio feedback component, a battery, interconnection circuitry, cables, and connections for an intraoral device. The camera component of the headset captures images during an activity to be analyzed, such as walking or viewing a room, and sends data (e.g., visual data) to the controller. The controller transmits the data to a database on the remote platform that includes software that instantly analyzes the image information represented in the data, then provides immediate feedback to the headset. The controller may independently process the data.
