Abstract
A method of, and apparatus for, determining if a person operating equipment is experiencing an elevated cognitive load, wherein the person's use of a device at a first time is monitored so as to set a baseline signature. Then, at a later time, the person's use of the device is monitored to determine the person's performance at the second time, as represented by a performance signature. This performance signature can then be compared against the baseline signature to predict whether the person is experiencing an elevated cognitive load.
Claims20
A method of determining if a person operating equipment is experiencing an elevated cognitive load, said method comprising the steps of:
- collecting a first set of data related to the person's operation of a device at a first time;
- processing said first set of data to establish a baseline signature;
- collecting a second set of data related to the person's operation of the device at a second time;
- processing said second set of data to establish a performance signature;
- and
- comparing said performance signature to said baseline signature to determine whether the person is experiencing an elevated cognitive load at said second time.
A computer-readable storage medium storing one or more sequences of instructions which, when executed by one or more processors, causes the one or more processors to perform a method of determining if a person operating equipment is experiencing an elevated cognitive load, said method comprising the steps of:
- collecting a first set of data related to the person's operation of a device at a first time when the person is not experiencing an elevated cognitive load;
- processing said first set of data to establish a baseline signature;
- collecting a second set of data related to the person's operation of the device at a second time;
- processing said second set of data to establish a performance signature;
- comparing said performance signature to said baseline signature to determine whether the person is experiencing an elevated cognitive load at said second time;
- and
- triggering a response if said person is experiencing an elevated cognitive load.
A computer-implemented method of determining if a person operating a device is experiencing an elevated cognitive load, said method comprising the steps of:
- a sensor measuring behavioral biometric data relating to the person's operation of a device to collect a first set of data related to the person's operation of said device at a first time when the person is not experiencing an elevated cognitive load;
- a computer-readable storage medium storing said first set of data;
- a processor processing said first set of data to establish a baseline signature;
- said sensor measuring behavioral biometric data relating to the person's operation of said device to collect a second set of data related to the person's operation of the device at a second time;
- said computer-readable storage medium storing said second set of data;
- said processor processing said second set of data to establish a performance signature;
- said processor comparing said performance signature to said baseline signature to determine whether the person is experiencing an elevated cognitive load at said second time;
- and
- said processor triggering a response if said person is experiencing an elevated cognitive load.
