A signal processing device includes a first acquisition section that acquires first illuminance information indicating illuminance of an inside of a moving body, a second acquisition section that acquires second illuminance information indicating illuminance to be compared with the first illuminance information, and a light adjusting control section that controls a light adjustment by a device included in the moving body on a basis of a result of a comparison between illuminance of the first illuminance information and illuminance of the second illuminance information.

A motion sickness countermeasure system for a user within a vehicle having a light array system configured to output visual stimuli presented in a field of view of the user; and a controller outputting a control signal to the light array system to activate the light array system in such a way as to mimic the visual input one would receive if one were to look outside the vehicle.

The invention concerns an optoelectronic apparatus comprising a light field pattern generating device with at least one light emitting element and at least one imaging optic, and a first sensor device, wherein the first sensor device is configured to determine the position of a body part, in particudefinilar the face, of a user of the optoelectronic apparatus relative to the light field pattern generating device, and wherein the light field pattern generating device is configured to generate at least one light field pattern on the body part of the user that is not directly visible to the user when looking in the direction of the light field pattern generating device, the light field pattern comprising at least a first area with a first illuminance and a second area with a second illuminance smaller than the first illuminance.

Disclosed is a motion sickness reduction system for vehicles, the motion sickness reduction system including an interface configured to exchange a signal with at least one electronic device mounted in a vehicle, at least one light output area located around a screen of at least one display, and a processor configured to provide a control signal for changing the pattern of light output from the light output area based on information about the state of the vehicle received from the electronic device.

A number of variations may include a system or method of monitoring vehicle control actions and communicating upcoming control actions, such as deceleration or lateral movement, to vehicle occupants prior to occurrence of the control action such that occupants are aware of upcoming vehicle control actions and occupant stress or anxiety may be reduced during operation of a vehicle.

A passenger state modulation system for passenger vehicles is presented. The passenger state modulation system operates to predict events that will impact the passengers state (e.g., motion sickness) before they happen and use the prediction to implement preemptive interventions with active vehicle sub-systems.

A vehicle is adapted for movement along a roadway. A cabin of the vehicle is adapted for surrounding and supporting an occupant with movement of the vehicle. Systems of the vehicle control an environment within the cabin.

A method and apparatus for preventing motion sickness of vehicle occupants are designed to display a motion image in a vehicle interior to convey visual information to the occupants regarding the vehicle's current and upcoming movements. The motion image typically includes a plurality of patterns with the same shape and different sizes arranged concentrically to create a three-dimensional image based on perspective representation, and changes the patterns in advance of upcoming vehicle movements. Thus, the occupants can perceive such moving patterns in their peripheral vision and consciously or unconsciously process and anticipate the vehicle movements, thereby enabling them to avoid or mitigate the experience of motion sickness.
