Abstract
A mobile device providing a mobile processing function such as a mobile telephone and/or a personal digital assistant. The mobile device includes a mobile device body, a processing system within the body, the processing system programmed to be part of providing the mobile processing function, a projector coupled to the body to project an image onto a substantially planar surface when the mobile device body is on the surface at a predetermined angle relative to the surface, and a pen-location transcription system coupled to the processing system to record the positions of a writing implement at a plurality of instants of time by transmitting energy between the writing implement and a device mechanically coupled to the mobile device body. In one version, the device mechanically coupled to the mobile device body is a sensor array including at least two sensors of the transmitted energy. The writing implement includes a transmitter of the transmitted energy. In another embodiment, the device mechanically coupled to the mobile device body includes one or more transmitters transmitting the energy, and the writing implement includes at one or more sensors of the transmitted energy.
