  • Patent number: 11880527
    Abstract: A device to enable touchless operation of an instrument is disclosed. The device includes an actuator configured to vibrate the instrument, a controller configured to control the actuator, and an interval detector configured to detect an interval between the instrument and an object to operate the instrument. The controller is configured to start vibrating the actuator having been still after the interval detected by the interval detector reaches a first threshold, keep vibrating the actuator until the interval detected by the interval detector reaches a second threshold larger than the first threshold after the interval reaches the first threshold, and stop vibrating the actuator after the interval detected by the interval detector reaches the second threshold.

  • Patent number: 11334167
    Abstract: A tactile presentation device includes a touch surface fixed in orientation, an actuator configured to vibrate the touch surface along one axis within the plane of the touch surface, and a controller configured to control vibration of the actuator along the one axis to present tactile stimulus to a finger in contact with the touch surface. The controller is configured to control the actuator in such a manner that direction to start vibration for presenting tactile stimulus to the finger is within a range from minus 43° to plus 43° with respect to a direction of gravity projected on the touch surface or the opposite direction thereof.

  • Patent number: 11002986
    Abstract: A display device as an embodiment of the present invention is provided with a light source, a light splitting portion for causing first emission light emitted from the light source to be surface-reflected as first reflected light, a retro-reflection portion for retro-reflecting the first reflected light toward the light splitting part as retro-reflected light, and a first light blocking portion for blocking surface-reflected light surface-reflected by the retro-reflection part toward an observation position of the retro-reflected light. The light splitting portion is configured to transmit at least some of the retro-reflected light.
