Method for selection of an object in a virtual environment

摘要

The invention relates to a method for selection of a first object in a first virtual environment, the first object being represented in the first environment with a size of value less than a threshold value. According to an exemplary embodiment, in order to make the selection of the first object more convivial, the method includes steps for: estimating a direction associated with a pointing gesture of a user, determining a second object according to the estimated direction, the second object having a size of value greater than the threshold value, and selecting of the first object according to the second determined object. The invention also relates to a multimedia terminal adapted for the implementation of the method for selection.

1. A method for selecting a first object of a first virtual environment, said first object being displayed on a display device of a real environment with a size value less than a threshold value, said method comprising:
determining a direction associated with a pointing gesture of a user; determining a second object associated with said first object, said second object corresponding to a first intersection between said second object and said determined direction when departing from a part of a body of said user making said pointing gesture, said second object having a size value greater than said threshold value and belonging to said real environment, said first object being different from a graphical representation of said second object, wherein said first intersection is calculated between a ray and a first element encountered by said ray, said ray: (i) having as origin, said part of said body of said user making said pointing gesture, (ii) having as direction, said direction associated with said pointing gesture and (iii) having as orientation, an orientation associated with said pointing gesture, and wherein when no object is intersected by said ray, an object closest to said ray and situated within a tolerance zone surrounding said ray is determined to be said second object; and selecting, by an avatar representing said user in said first virtual environment, said displayed first object according to said determined second object.
