    Abstract: Provided is a remote work-support system including a first display device to be worn on a first user working at a work site, a surrounding imaging device disposed on the work site, and an information processing device provided at a predetermined spot, configured to be communicable with the first display device and the surrounding imaging device, and operated by a second user. The first display device includes a first communication unit transmitting first image data to the information processing device. The surrounding imaging device includes a second communication unit transmitting second image data to the information processing device. The information processing device includes second display devices displaying the first and second image data, an operation unit through which data is input, and a third communication unit transmitting data input by the second user through the operation unit to the first display device.

    Abstract: In an optical scanner 100, a vibration portion 101 includes first and third elements 3021 and 3023 that vibrate a light guide path 102 in a direction substantially perpendicular to an optical axis direction, and second and fourth elements 3022 and 3024 that vibrate the light guide path in a direction substantially perpendicular to a vibration direction thereof. A driving signal is applied to each of electrodes 3011 to 3014, each of which corresponds to one electrode of each of the first to fourth elements, and the other electrode 3015 is used as a common electrode having a floating potential. A driving signal generator 1007 generates a driving signal such that a median value of driving signals Vy1and Vy2 applied to the first and third elements and a median value of driving signals Vx1 and Vx2 applied to the second and fourth elements correspond to substantially the same value.

    Abstract: To propose an optical scanning method for a video device including an optical scanning unit in which one end of a light guide path has a protruding beam-shaped structure. The video device includes the optical scanning unit having the light guide path in which light enters from one end and emits from the other end, and a vibration unit configured to apply vibration to the light guide path via a joint unit in a vicinity of the other end of the light guide path; a drive signal generation unit that generates a drive signal for inducing vibration in the vibration unit; and a scanning trajectory control unit which has a function of independently vibrating the light guide path in a first direction substantially perpendicular to an optical axis direction of the light guide path, and in a second direction substantially perpendicular to the optical axis direction of the light guide path and substantially perpendicular to the first direction by the vibration unit, and which generates a first drive signal configured to drive the vibration unit in the first direction and a second drive signal configured to drive the vibration unit in the second direction with any pattern. The scanning trajectory control unit generates the first drive signal and the second drive signal as sine waves having different phases and a substantially same frequency, and sets a modulation amount of an amplitude modulation of a sine wave of the second drive signal to be larger than a modulation amount of an amplitude modulation of a sine wave of the first drive signal.
