A handheld optical scanner for capturing images of text from a rendered document is described. The scanner includes a package suitable to be held in a user's hand. The package contains an optical sensor that captures images of text from a rendered document. The package also contains a proximity sensor that determines when the optical sensor is within a predetermined distance and orientation of a rendered document. The package further contains a triggering mechanism that causes the optical sensor to capture an image of text from a rendered document when the proximity sensor determines that the optical sensor is within a predetermined distance and orientation of a rendered document.
1. A handheld optical scanner for capturing images of text from a rendered document, comprising: a package adapted to be held in a hand of a user; andinside the package: an optical sensor that captures images of text from the rendered document;a proximity sensor that determines when the optical sens
1. A handheld optical scanner for capturing images of text from a rendered document, comprising: a package adapted to be held in a hand of a user; andinside the package: an optical sensor that captures images of text from the rendered document;a proximity sensor that determines when the optical sensor is within a predetermined distance and orientation of the rendered document; anda triggering mechanism that automatically causes the optical sensor to capture an image of text from the rendered document in response to the proximity sensor determining that the optical sensor is within the predetermined distance and orientation of the rendered document. 2. The handheld optical scanner of claim 1, further comprising an output indicator. 3. The handheld optical scanner of claim 2, further comprising a source of electrical energy used to power components of the handheld optical scanner, wherein the output indicator is configured to indicate whether the electrical energy source has been exhausted. 4. The handheld optical scanner of claim 2, wherein the output indicator is configured to indicate whether text recently scanned from the rendered document by the user should be re-scanned. 5. The handheld optical scanner of claim 2, further comprising a data interface for exchanging data between the scanner and a host, wherein the output indicator is configured to indicate whether the data interface is presently connected to the host. 6. The handheld optical scanner of claim 2, further comprising a gesture detection subsystem for detecting a performance of a gesture with the scanner, wherein the output indicator is configured to indicate whether the gesture detection subsystem has detected the performance of the gesture. 7. The handheld optical scanner of claim 2, further comprising a memory that stores images of text captured from the rendered document, wherein the output indicator is configured to indicate an extent to which a capacity of the memory has been consumed. 8. The handheld optical scanner of claim 2, wherein the output indicator is configured to indicate whether text recently scanned from the rendered document by the user is adequate to uniquely identify the rendered document. 9. The handheld optical scanner of claim 2, wherein the output indicator is configured to indicate whether text recently scanned from the rendered document by the user is adequate to uniquely identify an electronic document from which the rendered document was rendered. 10. The handheld optical scanner of claim 2 wherein the output indicator comprises a visual indicator. 11. The handheld optical scanner of claim 2 wherein the output indicator comprises an audio indicator. 12. The handheld optical scanner of claim 2 wherein the output indicator is configured to cause the package to vibrate. 13. The handheld optical scanner of claim 1, further comprising a memory for storing images of text captured from the rendered document. 14. The handheld optical scanner of claim 13, further comprising: a clock; anda timestamping module that associates with each image of text stored in the memory an indication of a time obtained from the clock when the image of text was captured from the rendered document. 15. The handheld optical scanner of claim 1, wherein the package is a housing for a mobile phone. 16. The handheld optical scanner of claim 1, wherein the proximity sensor determines when the optical sensor is within the predetermined distance and orientation of the rendered document based on image data received from the optical sensor.
