Abstract

A system and method for evaluating safety risk of workers is presented. The system includes wearable devices configured to be attached to or carried by workers during a work shift and a monitoring system. The wearable device includes sensors configured to sample sensor data indicative of working conditions and work performed by workers. The wearable device is configured to record an audio recording and communicate a set of data including the audio recording and/or sensor data to the monitoring system in response to an event trigger being engaged. In one or more arrangements, the monitoring system is configured to facilitate creation of a workflow for performance of a task described in the audio recording in response to receiving the set of data.

Claims (71)

1. A system for monitoring worker activity, comprising:

wherein in response to the event trigger being engaged, the wearable device is configured to record an audio recording using the sound sensor and communicate a set of data including the audio recording to the data processing system;

wherein the data processing system is configured to facilitate creation of a workflow for performance of a task related to the audio recording in response to receiving the set of data.

2. The system of claim 1 , wherein the data processing system includes software configured to automatically attach the audio recording to the workflow.

3. The system of claim 1 , wherein the data processing system includes software configured to automatically create a transcription of the audio recording and attach the transcription to the workflow.

4. The system of claim 1 , wherein the set of data includes data from two or more of the plurality of sensors.

5. The system of claim 1 , wherein the wearable device is configured to record the audio recording for a predetermined length of time after the event trigger is engaged.

6. The system of claim 1 , wherein the wearable device is configured to record the audio recording until the wearable device determines that the worker has stopped talking.

7. The system of claim 1 , wherein the wearable device is configured to record the audio recording for a length of time while the event trigger is engaged by the worker.

8. The system of claim 1 , wherein event trigger is a switch.

9. The system of claim 1 , wherein event trigger is a button.

10. The system of claim 1 , wherein the wearable device is configured to initiate an audio recording in response to data from one or more of the plurality of sensors satisfying a predetermined set of criteria.

11. The system of claim 1 , wherein the wearable device has a mechanism for the worker to determine whether the set of data is for a higher priority matter or a lower priority matter.

12. The system of claim 1 , wherein the wearable device has a mechanism for the worker to determine whether the set of data is for a higher priority matter or a lower priority matter;

wherein the wearable device is configured to communicate the set of data to the data processing system in response to determining the set of data is for a higher priority matter;

wherein the wearable device is configured to store the set of data for later communication to the data processing system in response to determining the set of data is for a lower priority matter.

13. The system of claim 1 , wherein the wearable device has a mechanism for the worker to determine whether the set of data is for a higher priority matter or a lower priority matter;

wherein when the set of data is determined to be a higher priority matter, the wearable device is configured to communicate the set of data to the data processing system using a first protocol;

wherein when the set of data is determined to be a lower priority matter, the wearable device is configured to communicate the set of data to the data processing system using a second protocol;

wherein the first protocol has a higher urgency level than the second protocol.

14. The system of claim 1 , wherein the wearable device is configured to determine whether the audio recording should be classified as a high priority matter or a low priority matter.

15. The system of claim 1 , wherein the wearable device is configured to determine whether the audio recording should be classified as a high priority matter or a low priority matter;

wherein when the set of data is determined to be a high priority matter, the wearable device is configured to communicate the set of data to the data processing system using a first protocol;

wherein when the set of data is determined to be a low priority matter, the wearable device is configured to communicate the set of data to the data processing system using a second protocol;
