Abstract
Methods and apparatus for adaptively mitigating motion sickness in an operator are provided herein. In some embodiments, a compensatory modulator for use with a display controller included in a system to adaptively mitigating motion sickness in an operator may include one or more inputs to receive at least one of physiological measurements of the operator or operator activity behavior from one or more monitoring devices, and a motion sickness expert system configured to (a) determine a cognitive state of the operator based on the received inputs, (b) compute mitigating display parameters based on the determined cognitive state of the operator, (c) output the computed mitigating display parameters to the display controller.
Claims22
A compensatory modulator for use with a display controller included in a system to adaptively mitigate motion sickness of an operator in a task, the compensatory modulator comprising:
- one or more inputs to receive at least one of physiological measurements of the operator or operator activity behavior from one or more monitoring devices;
- and
- a cognitive state expert system configured to (a) determine whether the operator is experiencing motion sickness by determining a cognitive state of the operator based on the received inputs, (b) compute mitigating display parameters based on the determined state of the operator to mitigate determined motion sickness for that operator, and (c) output the computed mitigating display parameters to the display controller.
A system for adaptively mitigating motion sickness, the system comprising:
- a display device configured to display a first primary image and a second compensatory image;
- a display controller coupled to the display device and configured to control display of the second compensatory image;
- and
- a compensatory modulator communicatively coupled to the display controller, the compensatory modulator including a cognitive state expert system configured to determine whether the operator is experiencing motion sickness by determining a cognitive state of the operator based on at least one of physiological measurements of the operator or operator activity behavior,
- wherein the display controller is configured to determine display parameters of the second compensatory image based on (a) a motion of the first primary image and the display device, and (b) computed mitigating display parameters based on the determined cognitive state of the operator from the compensatory modulator to mitigate determined motion sickness for that operator.
A method for adaptively suppressing motion sickness in an operator viewing a first primary image on a display device, the method comprising:
- measuring physiological characteristics and activity behavior of the operator while viewing the first primary image;
- determining whether the operator is experiencing motion sickness by determining a cognitive state of the operator while viewing the first primary image based on the measured physiological characteristics and activity behavior;
- computing mitigating display parameters based on the determined cognitive state of the operator to mitigate determined motion sickness for that operator;
- and
- displaying a second compensatory image on the display based on (a) a motion of the first primary image and the display device, and (b) the computed mitigating display parameters.
