## Abstract

There is provided a virtual reality (VR) contents providing system. The system includes a storage unit, a VR contents playing device, a sensor and a control unit. The storage unit stores a plurality of VR contents. The VR contents playing device provides a VR content among the VR contents. The sensor measures biometric information of a user of the VR contents playing device. The control unit is configured to receive the biometric information from the sensor, calculate reaction value for the user based on the biometric information every predetermined time interval, determine property information for a VR content to be played based on the reaction value, and control the VR contents playing device to play its VR content having the determined property information.
