Patent ID: 11301667

Abstract:
A smart user equipment (UE) connected to a head mounted display (HMD) worn on a user's head, for playing a video is disclosed. The smart UE includes an operation control module configured to recognize a predetermined user action by a sensor or a camera included in the smart UE and perform a control operation mapped to the user action. The smart UE enables the user to control an operation of the smart UE regardless of whether the HMD includes a separate control means by controlling the smart UE without removing the HMD through the operation control module. While the user is viewing video content including virtual reality, wearing the HMD, the smart UE autonomously detects a dangerous situation through situation awareness and notifies the user of the dangerous situation by an operation of recognizing an obstacle appearing in front of the user by using a rear camera which is installed at the rear of the smart UE and monitors the front of the user, and upon recognition of the obstacle, displaying a front view screen on a display unit included in the smart UE in real time, to enable the user to identify and cope with the dangerous situation without removing the HMD. When the distance between the user and the obstacle is equal to or less than a threshold, the smart UE discontinues the video play and displays only the front view screen.
