Abstract

Disclosed is an interaction system between a controller and a VR application. The interaction system includes a controller including a first actuator configured to move a mass and a first processor configured to control an operation of the first actuator; and a content execution device configured to execute an application according to a control signal received from the controller and generate a feedback signal to transmit the generated feedback signal to a controller when a virtual object change event occurs during the application execution, wherein the first processor of the controller controls the first actuator when the feedback signal is received to move the mass and move a center of gravity. According to the present disclosure, since the center of gravity and the length of the controller operated by the user in reality may be changed in linkage with a change of the virtual object displayed on the display while executing the VR application, it is possible to greatly improve the immersion and feeling of use of the user.
