  • Publication number: 20220076469
    Abstract: An information display device acquires information about the current location of the device and information about the orientation of the device when the device is directed to a targeted ground object. A map information storage unit stores map information and a target ground object identification execution unit identifies, on a map, the targeted ground object by use of the current location and orientation information. A specific information acquisition unit acquires specific information relating to the target ground object; and a related information acquisition unit acquires related information relating to the targeted ground object by using a search process based on the specific information. The target ground object identification execution unit identifies, from among the ground objects on the map that are located in the direction in which the information display device is directed, the closest ground object to the current location of the information display device on the map.

  • Publication number: 20220066733
    Abstract: The present invention relates to a head-mountable information processing apparatus allowing a user to hear a desired sound even if ambient sound unnecessary for the user is present. An audio input interface includes sound microphones worn in the vicinity of the user's ear, collects the ambient sound that occurs outside the head-mountable information processing apparatus, and converts the ambient sound into an input audio signal. An audio output interface, including headphones, converts a generated output audio signal for output, and emits the audio output toward the user. Based on a volume level of the input audio signal and a volume level of the output audio signal, a controller determines whether or not a state in which the ambient sound is preventing the audio for output from being heard is occurring, and based on a determination result, the controller controls a sound emission operation of the audio output interface.
