Abstract

The DC60 Universal Input Device provides a natural user interface for a variety of different computing platforms, including printed documents. Using the system shown, one could use the Universal Input Device to control various computer devices, as well as record handwritten electronic ink and electronic ink associated with new or stored documents. The Universal Input Device can be identified by specific identification to allow multiple users to operate on a single document and/or within an application program simultaneously. An optical system that compensates for infrared light brightness manages the viewing angle and helps detect positional coding that can be covered by the actual ink under normal visible light brightness.

Claims (21)

1. An input device is used to generate data representing handwritten strokes. This input device comprises: an image recording unit for recording an image of a specific area of material on which the input device is positioned and generating the recorded image data; a processing unit for processing the recorded image data; a memory unit for storing the handwritten stroke data based on the recorded image data; and an identifier for the input device, which the processing unit is configured to create a data frame for the signal medium to the external processing unit. This data frame encompasses pre-compressed stored data, forced recognition data, timestamp data, pre-compressed identifier data, and cyclic redundancy data. 2. The input device of claim 1 also includes a communication unit for transmitting data representing the movement of the input device to an external processing unit, such as for generating a signal representing handwritten input data. 3. The input device of claim number 2 therein, the external processing unit, is a digital personal assistant. 4. The receiving device of claim 2 thereto, the communication unit, is configured to transmit data representing wireless movement. 5. The receiving device of claim 4 therein is a communication unit, a communication unit that can be assigned an address. 6. The receiving device of claim 5 therein, the address of the communication unit, the address that matches the identifier of the receiving device. 7. The input device of claim 1 therein, the processor is configured to compress the recorded image data. 8. The input device of claim 1 is located therein; the input device identifier is positioned within the identifier compression data. 9. The receiving device of claim 1 herein, the identifier of which specifies the receiving device. 10. The input device of claim 1 herein, the recording unit, is configured to operate on a number of embedded interaction coding enabled display devices. 11. Of the input devices under claim 10 thereto, at least one embedded interaction coding enabled display device is configured to re-record the input data. 12. A system for receiving data from multiple input devices consists of: a processor for wirelessly receiving a data stream. This data stream represents data frames received from several input devices. The processor is configured to identify the first data frame in the data stream by a first identifier. This first identifier identifies the first input device, and to retrieve the first data frame from the data stream, it relies on the first identifier. This first data frame contains data representing handwritten strokes based on image data recorded by the first input device. This data frame encompasses; pre-compressed recorded image data, forced recognition data, timestamp data, pre-compressed identifier data, and cyclic redundancy data. 13. The system of claim number 12 herein, the processor is configured to identify the second data frame in the data stream by a second-order identifier. That second-order identifier identifies the second-order input device and to retrieve the value of the second data frame from the data stream based on the second-order identifier. Herein, that second data frame includes data representing handwritten strokes based on image data recorded by that second-order input device. 14. In the system of claim number 13, the processor is configured to store data retrieved from the data stream based on the first-order identifier, and data retrieved from the data stream based on the second-order identifier in memory. 15. The system of claims 12 therein, the first-order identifier is a specific number of data bits in the field of the first-order data frame as predefined. 16. The system of claim number 12 therein, the processor is configured to store the first data frame retrieved into memory. 17. Method for Ordering Data Frames in a Data Stream. This method consists of the following steps: obtaining a data stream representing a data frame from multiple input devices; assigning the identifier of the first input device to the first data frame of that data stream; assigning the first input device involves the identifier of that first input device; and storing that first data frame in memory on the associated first input device. That first data frame includes data representing handwritten strokes based on the image data recorded by that first input device. Specifically, the first data frame encompasses one pre-compressed image field, one time field, one pre-compressed identifier field, and one cyclic redundancy check field. 18. The system of claim 17 also includes the procedure of assigning the identifier of the second input device to the second data frame of the data stream. The assignment of the second input device involves the identifier of that second input device and the storage of that second data frame in memory based on the relevant second input device. There, that second data frame includes the data representing the handwritten strokes based on the image data recorded by that second input device. 19. In that manner of Claim 18, the primary input device identifier identifies the primary input device and the secondary input device identifies the secondary input device. 20. In that manner of claim 17, the identifier of the primary input device is determined, its position within the compression indicator field. 21. In that manner of claim 17, the identifier of the primary receiving device corresponds to the address of the communication unit, which determines the address associated with that primary receiving device.
