Abstract

A method of mapping the location of at least one object in three dimensional space, relative to an initial point in three dimensional space by an EIR terminal which contains a microprocessor, memory, a scanning device, a motion sensing device, and a communication interface. The method includes scanning a signal of decodable indicia located at a pre-defined area of a physical object, locating the decodable indicia within this signal, decoding the decodable indicia into a decoded message. The decoded message is an identifier for said physical object, which is then displayed. After receiving an interface command, the EIR terminal is placed in mechanical contact with the pre-defined area of the physical object and a first spatial position is stored as a point of origin in the EIR terminal.

Claims

1. A method comprising:

capturing, with a mobile device, an image comprising machine readable indicia that is associated with an area of a physical object;

decoding the machine readable indicia to obtain data identifying a physical location of the area and a physical structure of the physical object;

obtaining an initial value corresponding to an initial orientation of the mobile device;

scanning the area using the mobile device;

collecting a plurality of values corresponding to orientations and movements of the mobile device relative to the physical object over a period of time after collecting the initial value;

associating data of the collecting of the plurality of values corresponding to orientations and movements of the mobile device with data of the scanning of the area by the mobile device

formulating a path of movement of the mobile device based on the collected values and associated data; and

displaying, on a graphical user interface, a scan path the mobile device'"'"'s scanning of the area.

2. The method as claimed in claim 1 further comprising providing an indication to a user to aid the user about an occurrence of an event related to the capturing of the machine readable indicia.

3. The method as claimed in claim 2, wherein the indication is at least one of an audible feedback and visual cues on the graphical user interface.

4. The method as claimed in claim 1 further comprising, determining an object to be previously unscanned physical object based on the collected values, wherein the collected values includes at least one of a current location information, shelf configuration and dimensions, and previous scan paths.

5. The method as claimed in claim 4 further comprising:

providing the indication to a user about the previously unscanned physical object.

6. The method as claimed in claim 4, wherein the indication is provided upon occurrence of a plurality of activities, wherein the plurality of activities comprises at least one of:

a loss of accuracy in the collected values, a termination of determination of the scan path due to loss of accuracy of the collected values, a completion of scanning of all objects in stacks of an inventory, a determination of an object to be a previously unscanned object due to a pause in scanning activity of stacks in an inventory, and a determination of an object to be a previously unscanned object due to turning off of the apparatus by the user.

7. The method as claimed in claim 1 further comprising:

terminating the displaying of the scan path based on achieving a pre-determined error tolerance associated to the collected values.

8. The method as claimed in claim 7 further comprising:

activating at least one of a bar code scanner or a RFID reader of the apparatus alternatively for the scanning, when an error tolerance associated with the collected values exceeds the pre-determined error tolerance.

9. A method comprising:

capturing, with a mobile device, an image comprising machine readable indicia that is associated with an area of a physical object;

decoding the machine readable indicia to obtain data identifying a physical location of the area and a physical structure of the physical object;

collecting a plurality of values corresponding to orientations and movements of the mobile device relative to the physical object over a period of time;

determining a scan path of the area scanned by the mobile device based on the collected values; and

displaying, on a graphical user interface, the scan path the mobile device'"'"'s scanning of the area.

10. The method of claim 9, further comprising:

storing in the memory a first orientation of the apparatus at the point of origin; and

triggering an alert when the collected values received have reached a data noise threshold; and

triggering an alert when the threshold has been exceeded.

13. The method of claim 9, further comprising:

responsive to decoding the machine-readable indicia into a decoded message, querying a client using an identifier in the decoded message; and

receiving a response from the client wherein the response comprises descriptive information about the physical object.

14. The method of claim 9,

wherein responsive to detecting a communication interface command, making physical contact with the area of the physical object;

and

responsive to making contact with the area of the physical object, storing in the memory a first location of the apparatus as a point of origin.

15. A method comprising:
