Abstract
A transcription module having a mounting unit, acoustical receivers and an EM detector is disclosed. The mounting unit is adapted for positioning the transcription module over a work surface. First and second acoustical receivers are attached to the mounting unit. Each acoustical receiver includes a microphone positioned over a corresponding location on the work surface. Each microphone views the work surface at the corresponding location and is configured to receive acoustical signals from an input device operating over the work surface at another location. The EM detector detects an EM signal that is synchronized with the acoustical signals.
