Abstract:
Power usage of each of one or more devices belonging to a group is collected at prescribed intervals, and an authentication request including group identification information for identification of the group to be authenticated is received from a terminal. Upon receipt of the authentication request, a device as a manipulation target in the group and details of a manipulation on the device are determined, and notification is provided to the terminal. Whether the device designated by the notification is manipulated is judged on the basis of a change in the power usage of each of the devices belonging to the group. If the device designated by the notification is judged to be manipulated, authentication information is transmitted to the terminal.
Abstract:
A method of controlling a display control apparatus in a display system includes causing a display unit to generate a first certain image indicating a first presentation image to be overlapped on a certain object in display on a display medium on the basis of the recognized certain object; determining a wiping area wiped by a wiper on the display medium on the basis of detected position after the first presentation image is displayed on the display medium; and causing the display unit to generate a second certain image indicating a second presentation image resulting from deletion of a portion corresponding to the wiping area in the first presentation image in the display on the display medium.
Abstract:
A transmitting device is mountable in a vehicle. A first detector detects entry of another vehicle into vicinity of a vehicle mounted with the transmitting device. A second detector detects stabilization in a relationship between the other vehicle and the vehicle after the first detector detects the entry. A recording unit records a vehicle behavior of the vehicle from timing when the first detector detects the entry of the other vehicle to timing when the second detector detects the stabilization in the relationship between the other vehicle and the vehicle. A transmitter transmits the vehicle behavior recorded in the recording unit after the second detector detects the stabilization.
Abstract:
A visual field calculation apparatus capable of accurately calculating a visual field range of a user without using a complex configuration is provided. The visual field calculation apparatus includes a saccade detector that detects a saccade on the basis of a first gaze direction detected at a first timing and a second gaze direction detected at a second timing, a saccade speed calculator that calculates speed of the saccade on the basis of a time difference between the first timing and the second timing, the first gaze direction, and the second gaze direction, and a visual field range calculator that calculates a displacement vector of a saccade whose speed exceeds a first threshold, and calculates an area including a final point of the displacement vector as the visual field range of the user.
Abstract:
A device management method of a device management apparatus that manages information of devices installed in a home, includes: acquiring electric power consumption per unit time in predetermined time intervals, for each of branch circuits of a power distribution board to which the devices can be connected; estimating existence of the devices connected to the branch circuit, based on change of electric power consumption over time, per unit time; condition determining whether or not an estimated device, which is a device regarding which existence has been estimated in the estimating, satisfies a predetermined condition; and transmitting inquiry information to a user in accordance with the predetermined condition, only in a case where determination is made in the condition determining that the estimated device satisfies the predetermined condition.
