Description

Technical Field The disclosure relates to a device and method for providing power-saving management for each space based on user interaction. Background Art The enhancement of living standards is increasingly leading to the use of various types of electronic devices in home environments. Additionally, many of the newly released home electronic devices are smart devices that are capable of communicating with server devices and may be controlled based on such communication. With increasing awareness of resource depletion and environmental contamination issues, it is critical to reduce and streamline power consumption. Reducing power consumption and improving efficiency associated with the use of a large number of home electronic devices are also increasingly becoming important issues. Disclosure Technical Problem To streamline the power consumption of a large number of home electronic devices, the user's current state, e.g., the user's current location in the home, needs to be considered. However, if a sensor is used to detect and determine the user's current state, it may be difficult and burdensome to install additional sensors which can possibly increase a risk of infringing on the user's privacy as a result of transmitting the data detected by all the sensors. Provided is a device and method for reducing power consumption by estimating the presence or absence of a user for a given space based on user interaction or control information for home electronic devices, without raising concerns about privacy infringement, by directly detecting the user's current state with a sensor or providing the detection result over a communication link, and controlling the power or operational state of a plurality of electronic devices based on the estimation.

The first type signal may include at least one of a power turn-off signal for the first device, a designated operation end signal for the first device, and a signal indicating that a cessation of user interaction with the first device exceeds a predetermined time. The one or more instructions, when executed by the at least one processor, may further cause the device to set each of the one or more first devices to the power saving standby state by setting a duration of a power saving standby timer to a predetermined value. The one or more instructions, when executed by the at least one processor, may further cause the device to: classify the second device into an occupancy estimation group and store information related to the second device in the at least one memory, and set each of the one or more first devices to the power saving state based on identifying that the second signal is a second type signal related to predetermined characteristics of the occupancy estimation group. The one or more instructions, when executed by the at least one processor, may further cause the device to, based on identifying that the second signal is not the second type signal, extend the duration of the power saving standby timer. The one or more instructions, when executed by the at least one processor, may further cause the device to, based on not receiving the second type signal before an end of the duration of the power saving standby timer, release each of the one or more first devices from the power saving standby state. The second type signal may include a user input signal for activating an operation of the second device. The one or more instructions, when executed by the at least one processor, may further cause the device to store current state information corresponding to each of the one or more first d
