In one embodiment, a computing system may render an image to be output by a display which sequentially outputs pixel rows of the image at a row-to-row velocity. The system may predict, based on eye-tracking data, an eye-motion velocity within a timeframe for displaying the image. The system may determine a predicted retina projection displacement for each pixel row based on the row-to-row velocity and eye-motion velocity. The system may determine a first correction displacement for each pixel row based on the predicted retina projection displacement. The system may determine a cumulative correction displacement based on the first correction displacement. The system may determine, for each pixel row, a second correction displacement based on the first correction displacement of that pixel row and the cumulative correction displacement. The system may warp each pixel row using the associated second correction displacement and output the warped pixel rows using the display.

Wearable spectroscopy systems and methods for identifying one or more characteristics of a target object are described. Spectroscopy systems may include a light source configured to emit light in an irradiated field of view and an electromagnetic radiation detector configured to receive reflected light from a target object irradiated by the light source. One or more processors of the systems may identify a characteristic of the target object based on a determined level of light absorption by the target object. Some systems and methods may include one or more corrections for scattered and/or ambient light such as applying an ambient light correction, passing the reflected light through an anti-scatter grid, or using a time-dependent variation in the emitted light.

A system for producing image frames for display at display device. The system includes graphics processing units including first graphics processing unit and second graphics processing unit that are communicably coupled to each other and pose-tracking means. Second graphics processing unit is configured to: process pose-tracking data, to determine device pose and velocity and/or acceleration with which device pose is changing; execute rendering application(s) to generate framebuffer data corresponding to image frame; and send, to first graphics processing unit, framebuffer data and information indicative of device pose and velocity and/or acceleration. First graphics processing unit is configured to: execute first compositing application to post-process framebuffer data, based at least on said information; and drive light source(s) using post-processed framebuffer data to display image frame.

A configuration enables control of an image displayed on the display unit provided on the outer side of the transportation apparatus, such as a bus, resulting in increasing the degree of user attention and obtaining higher advertising effects. A display unit provided on an outer side of a transportation apparatus such as a bus; and an image control unit configured to execute control of a display image on the display unit, are included, and the image control unit executes control to change the display image on the display unit depending on a traveling state of the transportation apparatus. For example, the display image is varied depending on the states of whether the transportation apparatus is accelerating, decelerating, or constant speed traveling. Alternatively, an AR image using a real object near the transportation apparatus is generated for display.

A bar is displayed in a second region. Display of the bar starts in a longest state when an undetected state in which a region of interest is not detected transitions to a detected state in which the region of interest is detected, and display in the longest state is maintained until the detected state transitions to the undetected state. When the detected state transitions to the undetected state, the bar is reduced in length over time. When a predetermined time elapses, the length of the bar becomes 0, and the bar disappears. In addition, in a case where the undetected state transitions to the detected state before the bar disappears, the length of the bar returns to the longest.
