Abstract

Features are disclosed for a wearable scanning device that can passively initiate scanning for wireless identifiers such as RFID tags. The wearable scanning device may include a force sensor, an accelerometer, or a motion activated switch that can initiate the scanning when detecting an action performed by an associate (e.g., lifting) without an express intent from the associate to scan.

Claims

1. A wireless scanning device comprising:

a glove to be worn on at least a portion of a hand;

a pressure sensor attached to a first surface of the glove, the pressure sensor configured to detect a force exerted by an item held by the hand wearing the glove;

a wireless scanner affixed to the glove; and

a microcontroller affixed to the glove, and conductively coupled with (i) the pressure sensor, and (ii) the wireless scanner, the microcontroller configured to;

determine the force exceeds a lifting force threshold, wherein the lifting force threshold identifies a minimum force that indicates that an item has been lifted, and

activate the wireless scanner to detect wireless identifiers.

2. The wireless scanning device of claim 1, further comprising:

a display affixed to a second surface of the glove,

wherein the microcontroller is in data communication with the display, and

wherein the microcontroller is further configured to;

cause presentation of an output message via the display upon activation of the wireless scanner, the output message indicating that wireless identifiers are being scanned.

3. The wireless scanning device of claim 1, further comprising:

an antenna affixed to at least a portion of the glove and in electronic communication with the wireless scanner,

wherein the wireless scanner transmits wireless identifier read messages via the antenna, and

wherein the wireless scanner receives wireless identifier response messages via the antenna.

4. The wireless scanning device of claim 1, wherein the microcontroller is further configured to:

determine the force is less than the lifting force threshold; and

deactivate the wireless scanner to cease detecting wireless identifiers.

5. A wireless scanning device comprising:

a passively activated switch configured to activate in response to detecting a first interaction with an item, wherein the interaction occurs within a scanning area;

a wireless scanner configured to;

transmit a request message for detecting a wireless identifier, and

receive a response message from the wireless identifier; and

a microcontroller conductively coupled with (i) the passively activated switch, and (ii) the wireless scanner,

wherein the microcontroller is configured to, in response to the passively activated switch being activated, activate the wireless scanner to transmit the request message for detecting the wireless identifier and receive the response message from the wireless identifier.

6. The wireless scanning device of claim 5, further comprising a display in data communication with the microcontroller,

wherein the microcontroller is further configured to cause presentation of an output message via the display in response to activating the wireless scanner, the output message indicating that wireless scanner has been activated.

7. The wireless scanning device of claim 5, further comprising a vibrating motor in data communication with the microcontroller,

wherein the microcontroller is further configured to drive the vibrating motor at a first speed for a first period of time in response to activating the wireless scanner, the first speed and the first period of time associated with haptic feedback indicating that wireless scanner has been activated.

8. The wireless scanning device of claim 5, further comprising a wearable item,

wherein the microcontroller and the wireless scanner are enclosed in a housing, and

wherein the housing is detachably mounted on a surface of the wearable item.

9. The wireless scanning device of claim 8, further comprising an antenna included in at least a portion of the wearable item and in electronic communication with the wireless scanner,

wherein the wireless scanner transmits the read message for detecting the wireless identifier via the antenna, and

wherein the wireless scanner receives the response message from the wireless identifier via the antenna.

10. The wireless scanning device of claim 8, wherein the wearable item comprises a bracelet.

11. The wireless scanning device of claim 5,

wherein the passively activated switch is further configured to deactivate upon in response to detecting a second interaction with the item, and

wherein the microcontroller is configured to, in response to the passively activated switch detecting the second interaction with the item, deactivate the wireless scanner.

12. The wireless scanning device of claim 5,

wherein the first interaction with the item comprises lifting of the item,

wherein the passively activated switch comprises a force sensor, and

wherein the first interaction with the item is detected based at least in part on a comparison of a lifting threshold and a force value generated by the force sensor.

13. The wireless scanning device of claim 5, wherein the passively activated switch is further configured to deactivate in response to determining that a location of the wireless scanner is outside the scanning area.

14. The wireless scanning device of claim 5,

wherein the first interaction with the item comprises lifting of the item,

wherein the passively activated switch comprises an electrical circuit including a first contact and a second contact,

wherein the first contact and second contact close the electrical circuit when the item is lifted, and

wherein the first interaction with the item is detected from sensing a current through the electrical circuit closed by the first contact and the second contact.

15. A system comprising:

a data store storing specific computer-executable instructions; and

a first computing device in communication with the data store, the computing device including a processor that executes the specific computer-executable instructions to cause the system to at least;

receive a first value from a passively activated switch, the first value indicating that an item is moved;

determine a location of the passively activated switch; and

based at least in part on at least one of the location and the first value, activate a wireless scanner to;

(i) transmit a request message for detecting a wireless identifier, and (ii) receive a response message from the wireless identifier.

16. The system of claim 15, wherein the specific computer-executable instructions further cause the system to at least cause presentation of an output message via a display in response to activating the wireless scanner, the output message indicating that the wireless scanner has been activated.

17.
