Device and method for interactive video presentation

A device for performing computer-aided diagnosis (CAD) based on a medical image, comprising:

• a memory, storing computer-executable instructions;
• and
• a processor, coupled with the memory and, when the computer-executable instructions being executed, configured to:
• obtain video data corresponding to a story;
• present, via a display interface, a portion of the video data corresponding to a selected storyline path of the story;
• receive a user request for switching between a two-dimensional (2D) video streaming mode and a three-dimensional (3D) exploration mode;
• and
• in response to the user request being switching from the 2D video streaming mode to the 3D exploration mode:
• acquire 3D video scenes with exploration options for an avatar, the 3D video scenes matched to a current story status and currently presented video data;
• and presenting, via the display interface, the 3D video scenes with the exploration options.

A non-transitory computer-readable storage medium storing a plurality of instructions, wherein when the plurality of instructions are executed by a processor, cause the processor to:

• obtain video data corresponding to a story;
• present, via a display interface, a portion of the video data corresponding to a selected storyline path of the story;
• receive a user request for switching between a two-dimensional (2D) video streaming mode and a three-dimensional (3D) exploration mode;
• and
• in response to the user request being switching from the 2D video streaming mode to the 3D exploration mode:
• acquire 3D video scenes with exploration options for an avatar, the 3D video scenes matched to a current story status and currently presented video data;
