  • Patent number: 11327571
    Abstract: The present disclosure generally relates to a new computer input and tracking device, and method of using, more particularly, a new type of digital pen which tracks user hand movements to generate series of point coordinates that represent a drawing or hand writing. Unlike prior digital pens such as the Apple Pencil™ or the Microsoft Surface Pen™, the new system does not require users to write on a touch-sensitive surface. Users can write on any surface such as a notebook, a table, a board, or even in mid air. Users can draw two-dimensional or three-dimensional drawings. The new method utilizes a pen marked with one or more groups of distinct tracking marks or tracking patterns and a camera to track the pen in real-time. A computer running a 3D algorithm processes the camera images, detects and distinguishes the tracking marks, and uses the tracking marks to calculate the positions of the tip of the pen in three-dimensional space.

  • Patent number: 11284993
    Abstract: A display device (e.g., in a contact lens) is mounted on the eye. The eye mounted display contains multiple sub-displays, each of which projects light to different retinal positions within a portion of the retina corresponding to the sub-display. Additionally, a “locally uniform resolution” mapping may be used to model the variable resolution of the eye. Accordingly, various aspects of the display device may be based on the locally uniform resolution mapping. For example, the light emitted from the sub-displays may be based on the locally uniform resolution mapping.

  • Patent number: 11289037
    Abstract: In a display device with two liquid crystal cells, image quality deterioration depending on brightness and darkness of an environment is reduced. For this purpose, as an image signal for a liquid crystal display panel in which a display image is generated by light passing through a rear liquid crystal cell and a front liquid crystal cell, an image processing unit generates a rear image signal for the rear liquid crystal cell and a front image signal for the front liquid crystal cell. This image processing unit performs a spatial filter process on the rear image signal. Then, a filter control unit controls the spatial filter process performed on the rear image signal in the image processing unit on the basis of a detection value of an illuminance sensor that detects illuminance around the display panel.
