This document discusses emerging technologies in mobile brain-computer interfaces and augmented reality. It explores how electroencephalography and electromyography can be used for mobile interaction beyond touchscreens. It also examines current and upcoming technologies like NeuroSky brainwave sensors, Emotiv brain-computer interface caps, and mobile augmented reality. The document defines augmented reality and discusses key challenges like estimating the camera's position and orientation relative to the real world scene, and approaches to address these challenges including vision-based, sensor-based, marker-based and markerless methods.
