A head-up display for displaying graphics upon a windscreen of a vehicle includes a graphic projection module for generating one or more graphic images upon the windscreen of the vehicle, a forward-facing camera collecting image data representative of a view of a surrounding environment of the vehicle visible through the windscreen, an ambient light sensor detecting a level of ambient light present in the surrounding environment of the vehicle, and one or more controllers in electronic communication with the graphic projection module, the forward-facing camera, and the ambient light sensor. The one or more controllers executes instructions to determine the level of ambient light present in the surrounding environment of the vehicle based on an ambient light signal, and adjusts a saturation level of one or more colors of the one or more graphic images generated by the graphic projection module based on the level of ambient light.

A display system varies a size of a field of view area of a display for augmented reality (AR) applications based on at least one of ambient light in the environment and content displayed at the display and varying a brightness level of the field of view area such that the brightness level within the field of view area is inversely proportional to the field of view area. Based on an amount of ambient light detected in the environment of the display system, the display system adjusts the size of the area of the field of view of the display in inverse proportion to the amount of detected ambient light. As the size of the field of view area decreases, the display system increases the brightness level of the display within the field of view such that the brightness level is approximately inversely proportional to the field of view area.

A display controller (20) includes an information acquisition unit configured to obtain input data of attentional resources of an occupant of a mobile object such as traveling time, occupant status information, driving environment information or display image history and a display-image generation unit configured to generate, in a mode determined based on the input data, a display image to be displayed by a display device (10) provided for the mobile object. The mobile object is for instance a vehicle comprising a head-up display.

The present invention relates to a motorcycle helmet device. The device is comprised of a body that has at least one LED and/or LED panel, a visor, a projector, a battery and a mobile application. The at least one LED and/or LED panel can further be customized using the mobile application to allow a user to change the appearance of the body depending upon their preferences. The projector further allows a GPS navigation software to be projected onto the visor such that a user can view the software while driving a motorcycle without having to take his or her eyes off of the road. In addition, the projector can allow a user to customize the appearance of the visor.

A near-eye display device comprises a pupil-expansion optic, a laser, a drive circuit coupled operatively to the first and second lasers, a spatial light modulator (SLM), and a computer. The SLM has a matrix of electronically controllable pixel elements and is configured to receive emission from the laser and to direct the emission in spatially modulated form to the pupil-expansion optic. Coupled operatively to the drive circuit and to the SLM, the computer is configured to parse a digital image, trigger the emission from the laser by causing the drive circuit to drive a periodic current through a gain structure of the laser, and control the matrix of pixel elements such that the spatially modulated form of the emission projects an optical image corresponding to the digital image, wherein the periodic current includes plural cycles of modulation driven through the gain structure while the optical image is projected.
