  • Patent number: 10877567
    Abstract: An eyeglasses-type wearable device of an embodiment can handle various data inputs. The device includes right and left eye frames corresponding to positions of right and left eyes and nose pads corresponding to a position of a nose. Eye motion detection electrodes (sightline detection sensor electrodes) are provided with the nose pads to detect the eye motion of a user. Transmitter/receiver electrodes (capacitance sensor electrodes) of a gesture detector are provided with a part of the right and left eye frames to detect a gesture of the user. Various data inputs are achieved by a combination of input A corresponding to a gesture of the user detected by the gesture detector and input B corresponding to the eye motion of the user detected by the eye motion detector.

  • Publication number: 20200301322
    Abstract: A belt device includes a belt wound around a plurality of rollers, one of the plurality of rollers, and a belt contact member disposed on the one of the plurality of rollers. The belt rotates along with the plurality of rollers. The belt contact member faces an edge of the belt in an axial direction of the one of the plurality of rollers and includes a flat portion and a separation portion. The flat portion forms a plane perpendicular to the axial direction of the one of the plurality of rollers. The separation portion is disposed outboard of the flat portion in a radial direction of the one of the plurality of rollers and has a surface located farther from the edge of the belt than the flat portion in the axial direction of the one of the plurality of rollers.

  • Publication number: 20200293780
    Abstract: According to one embodiment, a system includes a wearable device configured to be attached to a display configured to display a display image. The wearable device features an optical component set featuring a lens, a first user operable member configured to set an adjustment value relating to a projection angle of the visual image, and a second user operable member configured to set an adjustment value relating to at least one of a color tone or a brightness of the visual image. A position of the visual image is changed by adjusting the projection angle of the visual image using the first user operable member so that the visual image is displayed at a position based on at least one of a shape or a size of the head of the user. The color tone or the brightness of the visual image is changed using the second user operable member.
