Abstract: An interactive interface system includes: a display device configured to display a picture on a display screen; and a sensor device configured to detect a position of a detection target. The interactive interface system further includes a calibration mode. The calibration mode is a mode of performing calibration between a display position on the display screen and a detection position by the sensor device, based on a detection result which is given by the sensor device and indicates a detected position of a marker present within the display screen.

Abstract: The work assistance system assists work including a plurality of steps. The work assistance system includes a determination unit and an announcement control unit. The determination unit determines, based on an image of a working area, whether a working result of a determination target step of the plurality of steps is acceptable or unacceptable. The announcement control unit orders an announcement unit to perform announcement operation when the working result of the determination target step has been determined to be unacceptable by the determination unit.

Abstract: A kitchen support system includes a projector, a voice recognizer, and a controller. The projector projects an image toward a cooking space in which cooking is performed. The voice recognizer recognizes content of voice which is input. The controller controls the projector to project a dish relating image including an order display image indicating order content of dish, and changes the dish relating image which is projected by the projector in accordance with recognition results of the voice recognizer.

Abstract: Provided is a planar light source device (300) having a planar light source with uniform luminance distribution by using a laser light source for outputting a beam-like luminous flux. The planar light source device (300) applies a laser beam from the side surface of a light guide plate (310) through a scanning mirror (330) and periodically scans the entire light guide plate. At that time, a light output (P(t)) of the laser light source (320) is modulated in synchronization with the scanning cycle so that the output is proportional to the temporal differentiation dS/dt of a scanning area (S(t)) from a search start within a scanning period. Thus, changes of the scanning speed and scanning length with time are eliminated and planar lighting with uniform luminance can be performed.
