Abstract

A system for decoding an encoded symbol character associated with a product is provided herein. The system includes an imager-based indicia reading terminal comprising a housing and a two-dimensional image sensor array and an imaging lens for focusing an image on the two-dimensional image sensor array. The terminal is adapted to read an encoded symbol character, and further adapted to image a hand gesture. The terminal includes a digital link to transmit the image of the hand gesture. The system further includes a memory coupled to the indicia reading terminal via a digital connection. The memory includes a hand gesture attribute library to associate predefined hand gestures with a terminal mode of operation. The system further includes a central processing unit connected to the digital link to receive the image of the hand gesture, correlate the image with the predefined hand gestures in the hand gesture attribute library, and execute the associated terminal mode of operation.

Claims

1. A system for decoding an encoded symbol character associated with a product, the system comprising:

an imager-based indicia reading terminal comprising a housing and a two-dimensional image sensor array and an imaging lens for focusing an image on the two-dimensional image sensor array, the two-dimensional image sensor array having a plurality of pixels formed in a plurality of rows and columns of pixels, the terminal adapted to read an encoded symbol character and further adapted to image a hand gesture, the terminal having a digital link to transmit the image of the hand gesture;

one or more memories coupled to the indicia reading terminal via a digital connection, at least one of the memories comprising a hand gesture attribute library to associate predefined hand gestures with a terminal mode of operation; and

one or more processors connected to the digital link to receive the image of the hand gesture, correlate the image with the predefined hand gestures in the hand gesture attribute library, and execute the associated terminal mode of operation.

2. The system of claim 1, wherein the imager-based indicia reading terminal has a hand-held form factor.

3. The system of claim 1, wherein the imager-based indicia reading terminal is a bioptic scanner.

4. The system of claim 1, wherein the image of the hand gesture indicates a numeral.

5. The system of claim 1, wherein the image of the hand gesture comprises an “

okay”

sign.

6. The system of claim 1, wherein the imager-based indicia reading terminal further comprises an input/output interface for providing communication with a device, the communication responsive to the terminal mode of operation.

7. The system of claim 6, wherein the image of the hand gesture comprises a distress signal, and the terminal mode of operation comprises sending a distress communication to the device.

8. The system of claim 7, wherein the device is a wireless transceiver.

9. The system of claim 7, wherein the device is a wired connection.

10. The system of claim 1, wherein the image of the hand gesture comprises sign language.

11. The system of claim 1, wherein the image of the hand gesture comprises a plurality of images comprising a hand in motion.

12. The system of claim 11, wherein the plurality of images comprises a hand in back-and-forth motion.

13. The system of claim 1, wherein the image of the hand gesture comprises a plurality of images in still motion for a predetermined time period.

14. The system of claim 1, further comprising a visual feedback indicator.

15. The system of claim 14, wherein the visual feedback indicator is a light.

16. The system of claim 15, wherein the light comprises a plurality of light emitting diodes.

17. The system of claim 16, wherein the light emitting diodes comprise the colors green, yellow, and red.

18. A method for changing the mode of operation for an indicia reading terminal, the method comprising the steps of:

providing an imager-based terminal having a housing and a two-dimensional image sensor array and an imaging lens for focusing an image on the two-dimensional image sensor array, the two-dimensional image sensor array having a plurality of pixels formed in a plurality of rows and columns of pixels;

providing one or more memories coupled to the terminal, at least one of the memories storing a hand gesture attribute library comprising a plurality of hand gesture attribute images, each of the images associated with a mode of operation for the terminal;

capturing an image with the imager-based terminal;

accessing the hand gesture attribute library and comparing the captured image to the stored hand gesture attribute images; and

if the captured image correlates with one of the stored hand gesture attribute images, executing the mode of operation associated with the hand gesture attribute image.

19. The method of claim 18, wherein the stored hand gesture attribute image comprises a distress signal, and the mode of operation associated with the distress hand signal is sending a distress communication to a device.

20. The method of claim 18, further comprising the step of providing feedback to indicate the terminal is prepared to execute the mode of operation associated with the hand gesture attribute image.

21. The method of claim 19, wherein the step of providing feedback comprises visually indicating on a display that a match has been achieved.

22. The method of claim 21, wherein the display shows the new mode of operation.

23. The method of claim 19, wherein the step of providing feedback comprises illuminating a light.

24. The method of claim 19, further comprising the step of requiring a confirmation before executing the mode of operation.

25. The method of claim 24, wherein the confirmation is a hand gesture.
