  • Publication number: 20230326251
    Abstract: A work estimation device (200) includes a watching region estimation unit (220), an object detection unit (210), a contact degree calculation unit (230), and a work estimation unit (250). The watching region estimation unit (220) estimates a watching region which is a region a user watches, with using information indicating a line of sight of the user. The object detection unit (210) detects, from a video that shows a work object the user is using and at least one target candidate object which is a candidate for a work target of the user, the work object and the at least one target candidate object. The contact degree calculation unit (230) calculates a contact degree indicating a degree of contact between the work object and each target candidate object which is included in the at least one target candidate object, on a basis of the watching region. The work estimation unit (250) estimates work of the user on a basis of the work object and the contact degree.

  • Patent number: 6348958
    Abstract: A color filter frame, which covers a non-display surface of an optical display section, is provided with frame color filter picture elements using at least two of three colors used for color filter picture elements, which correspond to displaying pixels. An area ratio of the frame color filter picture elements corresponding to different colors is set so as to be different from that of the color filter picture elements, which correspond to the colors used in the frame color filter picture elements. With this arrangement, it is possible to omit the step of manufacturing a black mask so as to reduce the cost; consequently, a color filter for an optical display device can be provided with an excellent appearance on a display.
