Abstract:
1. An information providing apparatus having a display unit and connected communicably to a storage unit, the information providing apparatus comprising: a reading unit reading dangerous range information indicating a dangerous range of each state of a dangerous target having a changing operating state, wherein the dangerous range changes depending on the operating state of the dangerous target, and dangerous target position information indicating a position of the dangerous target, which are stored in the storage unit; a position information obtaining unit obtaining apparatus position information calculated from information indicating a position of the information providing apparatus which is detected in a position detection device; a direction information obtaining unit obtaining direction information calculated from information indicating a direction of the information providing apparatus which is detected in a direction detection device; a posture information obtaining unit obtaining posture information calculated from information indicating a posture of the information providing apparatus which is detected in a posture detection device; a determination unit determining a visual field of the information providing apparatus based on the apparatus position information obtained in the position information obtaining unit, the direction information obtained in the direction information obtaining unit, the posture information obtained in the posture information obtaining unit, and visual field information of the information providing apparatus which is defined in advance; a display control unit determining a dangerous target included in the visual field based on the apparatus position information, the direction information, the posture information, and the dangerous range information and the dangerous target position information which are read in the reading unit, and generating a dangerous range image for the determined dangerous target and displaying the image on the display unit; and an input unit inputting a video imaged in an imaging device, wherein the display control unit calculates conversion information correlating a conversion between a coordinate system of a real space and a coordinate system of a display space by analyzing the video input by the input unit, calculates range coordinates corresponding to the dangerous range information based on coordinates of the dangerous target position information in the coordinate system of the real space, and applies the conversion information to the calculated range coordinates to generate the dangerous range image.
