For example, rather than recognizing the situation of the user's emotional state by considering one situation information collected through a sensor that measures heart rate, a sensor that measures the amount of sweat along with a sensor that measures the heart rate, and the ambient temperature By simultaneously considering a plurality of situation-aware information collected through a measuring sensor or the like, it is possible to more accurately recognize the situation of the user's emotional state. Therefore, the device for context awareness collects context information through a module capable of measuring surrounding environment information and provides it to the user.

However, the conventional device for situational awareness attaches sensors to the user's body or peripheral devices, or recognizes the user's situation as the user requests to directly measure the surrounding environment information, so it is always recognized that the user measures the surrounding environment information. Are doing. Therefore, since the user must intervene in order to collect context-aware information, additional time or effort is required from the user's point of view. Therefore, the conventional device for situation recognition has a problem in that it is difficult to naturally grasp the user's situation without the user's separate intervention while the user lives daily.

In addition, conventionally, since the user's terminal device does not infer and analyze the information that recognizes the user's situation, the user can only check the location information of the user through the terminal device, and the current situation of the user cannot be accurately identified. There is a problem that it is not possible to accurately recognize the situation of.
