A content distribution apparatus generates a group of contents to be sent to a content display apparatus that can continuously display contents of the same attribute. When a first content is newly added to the group, the content distribution apparatus determines the attribute of the first content as the attribute of the group. When adding a second content to the group, if the attribute of the second content coincides with the attribute of the group, the content distribution apparatus adds the second content to the group. The content distribution apparatus sends a content included in the group to the content display apparatus.

A wearable device apparatus, comprises: a first and second housings configured to be connected with each other; a plurality of light emitters configured to be separately located and configured to emit a light through the first housing; a light guide configured to guide a direction of the light emitted from the plurality of light emitters; a plurality of force detection sensor configured to detect a force applied to a certain point of the first housing; and a control board configured to control the plurality of light emitters through detection of the plurality of force detection sensors.

A vehicle display device includes a display and an electronic control unit. The electronic control unit is configured to detect an object and display at least one of a first virtual image in a first display mode and a second virtual image in a second display mode. The first virtual image and the second virtual image correspond to the detected object. The second display mode has a higher recognition possibility of a driver for presence of the object than the first display mode. The electronic control unit is configured to calculate a first region and a second region. In the first region, it is easier for the driver to acquire information than in the second region. The electronic control unit is configured to display the second virtual image in the second region, and the first virtual image in the first region according to a detection position of the object.

A feeling is given that a stationary object having any contour shape is moving. An image generation device comprises means for generating video including a stationary object area, at least one luminance varying area located along a contour of the stationary object area, and a background area other than the stationary object area and the luminance varying area. Luminance of the luminance varying area varies with time in a luminance range based on luminance of the stationary object area and luminance of the background area, and the luminance varying area is a portion that does not overlap the stationary object area in at least one area obtained by moving and/or enlarging the stationary object area.

An object including a final target that is equivalent to an object obtained by a superposition of three objects of a target, a dark object, and a light object with approximately the same shape, a superposition of two objects of a target and a dark object with approximately the same shape or approximately similar shapes, or a superposition of two objects of a target and a light object with approximately the same shape or approximately similar shapes is arranged in a background of which luminance periodically varies over time. However, luminance of the dark object is lower than luminance of the target, luminance of the light object is higher than the luminance of the target, and the superposition described above is an incomplete superposition in which a part of the dark object and/or a part of the light object is hidden by the target.

An example device for providing display modes can include a display that includes a plurality of light sources and a collimated backlight, a driver coupled to a switch that is coupled to the plurality of light sources with a first electrical connection for a first mode and a second electrical connection for a second mode, wherein the first electrical connection provides a first amperage to the plurality of light sources and the second electrical connection provides a second amperage to the plurality of light sources, and a computing device comprising instructions executable by a processing resource to: initiate the first mode by providing an instruction to the switch to activate the first electrical connection, and initiate the second mode by providing an instruction to the switch to activate the second electrical connection.

An instrument panel may include a multi-layer display including a first display panel and second display panel arranged in a substantially parallel manner, a backlight configured to provide light to the first display panel and the second display panel of the multi-layer display system, and a processing system comprising at least one processor and memory. The processing system may be configured to: display content including an object on a first display panel; divide the object into a plurality of segments; assign to each divided segment a position in a time sequence; and responsive to instructions, display, on the second display panel, segments corresponding to the segments of the object displayed on the first display panel, wherein the segments displayed on the first and second display panel are animated by varying optical properties of each segment according to the positions assigned the segments in the time sequence.

To create an illusion that a target which has an arbitrary contour shape and which is actually not moving is perceived to be moving. An object including a final target that is equivalent to an object obtained by a superposition of three objects of a target, a dark object, and a light object with approximately the same shape, a superposition of two objects of a target and a dark object with approximately the same shape or approximately similar shapes, or a superposition of two objects of a target and a light object with approximately the same shape or approximately similar shapes is arranged in a background of which luminance periodically varies over time. However, luminance of the dark object is lower than luminance of the target, luminance of the light object is higher than the luminance of the target, and the superposition described above is an incomplete superposition in which a part of the dark object and/or a part of the light object is hidden by the target.

According to one implementation, an image generation system includes a base having a rotor and a motor for spinning the rotor about an axis of rotation, and a display secured to the rotor, wherein a center of mass of the display is situated off of the axis of rotation. Such an image generation system also includes a first counterweight coupled to the rotor and having a first location relative to the rotor, and a second counterweight coupled the to the rotor and having a second location relative to the rotor different than the first location. The first counterweight and the second counterweight are configured to stabilize the display while the display is spun by the motor and the rotor.
