Abstract
A method of controlling a viewpoint of a user or a virtual object on a two-dimensional (2D) interactive display is provided. The method may convert a user input to at least 6 degrees of freedom (DOF) structured data according to a number of touch points, a movement direction thereof, and a rotation direction thereof. Any one of the virtual object and the viewpoint of the user may be determined as a manipulation target based on a location of the touch point.
Claims14
A method of controlling a virtual object or a viewpoint of a user on a two-dimensional (2D) interactive display, the method comprising:
- displaying a virtual manipulation medium as a user interface to manipulate the virtual object, displayed on a screen, or the viewpoint of the user;
- determining, as a manipulation target, any one of the virtual object and the viewpoint of the user, based on a touch point by a user input;
- converting the user input to at least 6 degrees of freedom (DOF) structured data according to a number of touch points, a movement direction thereof, and a rotation direction thereof;
- and
- controlling the manipulation target using the at least 6DOF structured data.
A method of processing multi-touch structured data, the method comprising:
- receiving, from a multi-touch driver, the multi-touch structured data that is associated with a user input via a virtual manipulation medium;
- extracting, from the multi-touch structured data, a number of touch points, a movement direction thereof, a location thereof, and a rotation direction thereof;
- and
- converting the multi-touch structured data to at least 6 degrees of freedom (6DOF) structured data, based on the number of touch points, the movement direction thereof, the location thereof, and the rotation direction thereof.
A method of processing a virtual manipulation medium that is used to control a virtual object or a viewpoint of a user on an interactive display, the method comprising:
- receiving, from a user input via the virtual manipulation object, at least 6 degrees of freedom (6DOF) structured data, wherein the at least 6DOF structured data is generated based on a number of touch points, a movement direction thereof, a location thereof, and a rotation direction thereof;
- determining, as a manipulation target, any one of the virtual object, displayed on a screen, and the viewpoint of the user, based on the location of the touch point;
- displaying, as a user interface, the virtual manipulation medium in any one of a region including the virtual object and a region excluding the virtual object, depending on whether the virtual object is determined as the manipulation target or the viewpoint of the user is determined as the manipulation target;
- and
- applying a video effect or an audio effect to the manipulation target that is any one of the virtual object and the viewpoint of the user.
