Disclosed herein is a system for automatic detection of music listening reactions, comprising a wearable sensor and a mobile device. The wearable sensor is worn on the listener's ear. The mobile device receives an inertial signal and a sound signal of the listener from the wearable sensor. The mobile device determines a vocal reaction of the listener based on the inertial signal, the sound signal and music information of the music being played and a motion reaction of the listener based on the inertial signal and the music information. Other embodiments are described and shown.

Disclosed herein is a communication device, which comprises a user trace manager, a power emulator, and a power impact estimator. The user trace manager manages a user's sensor usage trace and device usage trace, which shows the user's mobile device usage pattern. The power emulator executes an executable file of the mobile application to generate hardware usage statistics based on the sensor usage trace and the device usage trace. And the power impact estimator computes an increase in power consumption of the mobile application based on the hardware usage statistics.

Communication device for predicting power consumption of mobile application, communication system including same, method of predicting power consumption of mobile application and method of providing predicted power consumption of mobile application, using same

Disclosed herein are a server, system, method, and recording medium for searching for missing children, using mobile crowdsourcing. According to an embodiment, a server for searching for missing children, using mobile crowdsourcing, comprises a communication unit and a control unit. The communication unit receives a missing-child incident signal from a guardian terminal (held by a parent or guardian) and receives a first location information as to movements of a missing child from a child terminal (carried by the missing child) and sends the first location information received to at least one assistance terminal and receives landmark information from the assistance terminal(s) when a (degree of) similarity between the first location information sent to the assistance terminal(s) and a second location information detected by the assistance terminal(s) is higher than a preset value. The control unit generates a movement or moving path of the missing child, using the landmark information received.
