摘要： A system is provided in which a mobile display device, such as a cellular phone, a computing tablet, a mobile computer or any other portable device that incorporates a computing element and a display element, is adapted to display a predetermined pattern. The pattern can be either visible or invisible to human eye. An image sensor (most likely, but not necessarily, an optical one) detects said pattern, and the location of the MDD is determined in relation to the sensor. In one embodiment, the MDD displays a pattern on the device's standard display, for example four points of unique character, such as color or blinking pattern. Such a method will allow a cost-effective way to implement the system, as it requires no additional cost in hardware. In another embodiment, the system recognizes the display unit of the MDD (instead of a specific pattern on the MDD's display) and can determine location of the MDD without any change to the MDD's hardware or software. In yet another embodiment, the system includes bi-directional wireless communication between the receiver and the MDD and software that allows the MDD to exchange information with the system, such as the exact dimensions of the display.

摘要： 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.
