Abstract: A positioning apparatus comprises an acquiring section which acquires an azimuth angle and an angular velocity of a moving object from values measured by sensors of the moving object moving in a positioning area; a storage section which stores a coefficient of a relational expression established between a moving speed and a standard deviation of the angular velocity of the moving object in association with each of a plurality of division areas for dividing the positioning area; and a positioning section which specifies a division area where the moving object is positioned per unit time to acquire the stored coefficient in association with the division area, and calculates the moving speed in the division area from the coefficient and the standard deviation of the acquired angular velocity to measure a position of the moving object in the positioning area from the moving speed and the acquired azimuth angle.

Abstract: According to one embodiment, a position estimation device includes a first acquisition unit, a determination unit, and an estimation unit. The first acquisition unit acquires a first position of a moving body. The determination unit determines that direct wireless communication is possible between a terminal device and a communication device riding on the moving body. When the direct communication is possible, the estimation unit regards a position of the moving body as a position of the terminal device.

Abstract: An information processing device includes a camera configured to capture an image, a display including a touch panel and configured to display the image captured by the camera, a sensor configured to specify a position of the information processing device, and a processor. The processor being configured to, upon receipt of an input of a tap operation on the display of the captured image, calculating three-dimensional coordinates corresponding to an item in the captured image based on the position of the information processing device and the position of the tap operation on the captured image. The processor generating and outputting comment information including a comment received from a user of the information processing apparatus and the calculated three-dimensional coordinates.
