Abstract:
1. A pre-assembled apparatus in or for a projector configured to project an image onto a projection surface, the pre-assembled apparatus comprising: built-in components including electronic components, the built-in components having one or more identifiable characteristics, wherein the projector is configured to be upgradeable by a user connecting the pre-assembled apparatus to at least one external module to form an upgraded projector that is operable as an electronic transcription apparatus having a particular set of one or more transcription capabilities, the particular set of one or more transcription capabilities including the capability that when a pointing device that includes at least one transmitter of ultrasound and at least one transmitter of electromagnetic energy transmit ultrasound and electromagnetic energy, the transmitted energy is sensed by a plurality of sensors included in the pre-assembled apparatus or in the external module, and the sensed energy is used to determine the position of the pointing device on or near the projection surface, wherein the particular set of one or more transcription capabilities, including what mode or modes of operation are operative for the transcription apparatus, are automatically identified from a plurality of possible sets of capabilities by the connecting to the at least one external module, wherein the plurality of sensors include at least two ultrasound sensors at pre-defined or determinable positions relative to each other, and a sensor of electromagnetic energy, wherein the characteristics are identifiable in that when the pre-assembled apparatus is connected to at least one of the one or more external modules, at least one identifiable characteristic is identified and the identification causes one or more of the capabilities of the resulting transcription apparatus to be defined, wherein the at least one external module includes at least one of: one or more of the sensors; a video component; an audio component; a component to match a built-in RFID component; a USB connector; a network component; a component with a processor storage with software in the storage; the projector; a small display; one or more interaction elements to provide a user interface; one or more input devices; one or more environmental sensors; and a stylus, and wherein the particular set of one or more of the identifiable characteristics includes at least one of: the number and nature of the sensors, whether the built-in or the external module has the plurality of sensors, one or more identifiable characteristics of a connector; identifiable wireless connection characteristics of components for a wireless connection to an external module; RFID component to provide an identifiable connection using RFID; at least one of data encryption and a unique key; and one or more authorization characteristics.
