Abstract

Described herein is a method for alerting of personal risk in the workplace through a wearable indication signifying a risk condition that includes generating a set of workplace predictors of risk relating to accidents, injury, and industrial hygiene, based on at least one worker state that includes at least one of a physical state, a cognitive state, and an emotional state, and alerting a worker endangered by a predicted elevated risk to the existence of the predicted elevated risk by sending a perceivable alert to the worker. A system for alerting of personal workplace risk is also described.

Claims

1. A method for alerting of personal risk in the workplace to a worker, comprising:

generating, in computer memory, a set of workplace predictors of risk relating to accidents, injury, and industrial hygiene events based on at least one worker state that includes at least one of a cognitive state and an emotional state, based on collected information including at least video data, by compiling a sequence of states; and

communicating to a worker an existence of a predicted elevated risk.

2. The method of claim 1, further comprising:

communicating by a workplace machine manager to a workplace machine the predicted elevated risk.

3. The method of claim 1, further comprising:

acting in accordance with an associated remedial action stored on a workplace machine manager, in response to the predicted elevated risk.

4. The method of claim 1, wherein the set of workplace predictors are generated by developing a cognitive suite of workplace hygiene and injury predictors comprising:

categorizing worker states using unsupervised learning from video data and personal wearable data collector analysis;

categorizing sequences of worker states using supervised learning to determine the sequences of worker states that predict an accident event; and

compiling the sequence of states that are predictive of an industrial hygiene or workplace injury event from the categorizing of worker states using unsupervised learning and the categorizing of sequences of worker states using supervised learning.

5. The method of claim 1, wherein the at least one worker state further includes a physical state.

6. The method of claim 1, further comprising communicating an instruction to a machine operated by a worker to modify machine operation as a result of the predicted elevated risk.

7. The method of claim 1, further comprising:

determining a respective worker risk profile and machine use profile for each worker in a set of workers; and

determining one of more areas of training for at least one worker in the set that is appropriate to the worker risk profile and machine use profile for the at least one worker.

8. A system for alerting of personal risk in the workplace, comprising:

one or more servers having a processor;

a workplace hygiene and injury predictor, for predicting a risk of accidents, injury, and industrial hygiene events in the workplace through consideration of categorized information on worker states obtained by unsupervised learning and supervised learning;

an elevated risk determiner, for determining the existence of a predicted risk of an accident, injury, and industrial hygiene event.

9. The system of claim 8, wherein the workplace hygiene and injury predictor further comprises a compiler, for compiling a cognitive suite of workplace hygiene and injury predictors generated by:

categorizing worker states using unsupervised learning from video data and personal wearable instrumentation analysis;

categorizing sequences of worker states using supervised learning to determine the corresponding sequences of worker states that predict an accident event; and

compiling the sequence of states that are predictive of an industrial hygiene or workplace injury event from the categorizing of worker states using unsupervised learning and the categorizing of sequences of worker states using supervised learning.

10. The system of claim 8, further comprising a video data collector and a worker personal information collector, for collecting information on worker states.

11. The system of claim 8 further comprising a work place machine manager, wherein the workplace machine manager sends instructions to a workplace machine based on a risk profile of a worker.

12. The system of claim 8, further comprising a workplace machine manager, for modifying operation of a workplace machine during a predicted elevated risk condition.

13. The system of claim 8, further comprising a workplace machine manager, for authorizing a workplace machine to return to normal operation when a predicted elevated risk subsides.

14. The system of claim 8 , further comprising a worker warning manager, for transmitting a signal directed to a worker exposed to a predicted elevated risk.

15. A computer program product alerting of personal risk in the workplace to a worker, the computer program product comprising a non-transitory computer readable storage medium having program instructions embodied therewith, the program instructions executable by a computer to cause the computer to perform a method comprising:

generating a set of workplace predictors of risk relating to accidents, injury, and industrial hygiene, based on at least one worker state that includes at least one of a cognitive state and an emotional state, based on collected information including at least video data, by compiling a sequence of states that are predictive of an industrial hygiene or workplace injury event.

16. The computer program product of claim 15, wherein the program instructions executable by a computer cause the computer to perform the method including communicating by a workplace machine manager to a workplace machine a predicted elevated risk.

17. The computer program product of claim 15, wherein the program instructions executable by a computer cause the computer to perform the method including generating a set of workplace predictors, wherein the at least one worker state further includes a physical state.

18. The computer program product of claim 15, wherein the program instructions executable by a computer cause the computer to perform the method that includes generating a set of workplace predictors by:

categorizing worker states using unsupervised learning from video data and personal wearable instrumentation analysis;

categorizing sequences of worker states using supervised learning to determine the corresponding sequences of worker states that predict an accident event; and

compiling the sequence of states that are predictive of an industrial hygiene or workplace injury event from the categorizing of worker states using unsupervised learning and the categorizing of sequences of worker states using supervised learning.

19. The computer program product of claim 15, wherein the program instructions executable by a computer cause the computer to perform the method including a workplace machine manager authorizing a workplace machine to return to normal operation when a predicted elevated risk subsides.

20. The computer program product of claim 15, wherein the program instructions executable by a computer further comprise communicating an instruction to a machine operated by a worker to modify machine operation as a result of the predicted elevated risk.
