Abstract

A method of automatically providing information from a portable computing device to a bar code reader can include, within the portable computing device, automatically detecting a scan from the bar code reader. Responsive to the automatic detection of the scan, one or more segments of a visual image can be presented on a display screen of the portable computing device.

Claims

1. A method of providing information from a portable computing device to a bar code reader comprising:

within the portable computing device, detecting a scan from the bar code reader; and

responsive to said detecting step, presenting on a display screen of the portable computing device, at least one segment of a visual image.

2. The method of claim 1, said automatically detecting step further comprising automatically detecting light emanating from the bar code reader.

3. The method of claim 1, wherein said at least one segment comprises an entirety of the visual image.

4. A method of providing information from a portable computing device to a bar code reader comprising:

within the portable computing device, detecting a first scan from the bar code reader;

responsive to said step of detecting the first scan, presenting on a display screen of the portable computing device a first segment of a visual image;

detecting a second scan from the bar code reader; and

responsive to said step of detecting the second scan, presenting on the display screen a next segment of the visual image.

5. The method of claim 4, further comprising:

detecting further scans from the bar code reader; and

for each detected further scan, presenting upon the display of the portable computing device a next segment of the visual image until each segment of the visual image has been displayed.

6. The method of claim 4, wherein each said detecting step comprises detecting light emanating from the bar code reader.

7. A method of providing information from a portable computing device to a bar code reader comprising:

responsive to a detected event, presenting on a display screen of the portable computing device a first segment of a visual image; and

sequentially presenting upon the display of the portable computing device, further segments of the visual image, wherein each further segment of the visual image is displayed for a predetermined amount of time.

8. The method of claim 7, wherein prior to said step of presenting the first segment, said method further comprises:

detecting a user command; and

generating the event in response to the detected command.

9. The method of claim 7, wherein prior to said step of presenting the first segment, said method further comprises:

detecting a scan from the bar code reader; and

generating the event in response to the detected scan.

10. A portable computing device for displaying visual images comprising:

a display which is capable of presenting at least one segment of a visual image to be read by a bar code reader;

a sensor configured to detect a scan from the bar code reader; and

a processor configured to instruct said display to present the at least one segment of the visual image responsive receiving a signal from said sensor indicating that a scan from the bar code reader was detected.

11. The portable computing device of claim 10, further comprising:

a memory for storing a plurality of segments of the visual image.

12. The portable computing device of claim 11, wherein said sensor is configured to detect multiple scans by the bar code reader and provide a signal to said processor for each detected scan, and wherein said processor is configured to send to said display a next segment of the visual image to be presented upon the display for each signal received from the sensor.

13. The portable computing device of claim 11, wherein said processor is configured to send to said display further segments of the visual image to be presented upon the display, wherein each further segment is displayed for a predetermined amount of time.

14. The portable computing device of claim 10, wherein said display is a liquid crystal display.

15. A machine readable storage, having stored thereon a computer program having a plurality of code sections executable by a machine for causing the machine to perform the steps of:

within a portable computing device, detecting a scan from a bar code reader; and

responsive to said detecting step, presenting on a display screen of the portable computing device, at least one segment of a visual image.

16. The machine readable storage of claim 15, said automatically detecting step further comprising automatically detecting light emanating from the bar code reader.

17. The machine readable storage of claim 15, wherein said at least one segment comprises an entirety of the visual image.

18. A machine readable storage, having stored thereon a computer program having a plurality of code sections executable by a machine for causing the machine to perform the steps of:

within a portable computing device, detecting a first scan from a bar code reader;

responsive to said step of detecting the first scan, presenting on a display screen of the portable computing device a first segment of a visual image;

detecting a second scan from the bar code reader; and

responsive to said step of detecting the second scan, presenting on the display screen a next segment of the visual image.

19. The machine readable storage of claim 18, further comprising:

detecting further scans from the bar code reader; and

for each detected further scan, presenting upon the display of the portable computing device a next segment of the visual image until each segment of the visual image has been displayed.

20. The machine readable storage of claim 18, wherein each said detecting step comprises detecting light emanating from the bar code reader.

21. A machine readable storage, having stored thereon a computer program having a plurality of code sections executable by a machine for causing the machine to perform the steps of:

responsive to a detected event, presenting on a display screen of a portable computing device a first segment of a visual image; and

sequentially presenting upon the display of the portable computing device, further segments of the visual image, wherein each further segment of the visual image is displayed for a predetermined amount of time.

22. The machine readable storage of claim 21, wherein prior to said step of presenting the first segment, said method further comprises:

detecting a user command; and

generating the event in response to the detected command.

23. The machine readable storage of claim 21, wherein prior to said step of presenting the first segment, said method further comprises:

detecting a scan from the bar code reader; and

generating the event in response to the detected scan.
