Abstract: According to at least one embodiment, an information display device includes a receiver and a display. The receiver is configured to receive, from one or more devices, information indicating power consumption of one or more spaces in which electronic devices can be installed and/or one or more electronic devices. The display controller is configured to display animations corresponding to the power consumption of the one or more spaces and/or one or more electronic devices, such that differences in the power consumption among the one or more spaces and/or one or more electronic devices are displayed as differences in animation speeds.

Abstract: According to one embodiment, an electronic device includes an input display controller, a converter, a transmitter. The input display controller displays a setting area for setting one or more control parameters with respect to lighting control of a lighting device on a display and to accept a touch operation on the setting area. The converter converts position coordinates of the touch operation on the setting area into the one or more control parameters corresponding to the position coordinates. The transmitter transmits a control command indicative of the one or more control parameters to the lighting device and to transmit, when the touch operation is continuously performed for a first duration, a first control command indicative of one or more first control parameters corresponding to the position coordinates of the touch operation continuously performed for the first duration to the lighting device at a first transmission interval.
