Dynamic Viewpoint Switching for Virtual Display Media
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional information processing systems struggle to generate terminal images that effectively support various user activities in virtual spaces, particularly in terms of movement operations and dialog between users, due to a fixed viewpoint of the virtual camera linked to the avatar.
Innovation Solution
An information processing system that includes a drawing portion for terminal images, an acquisition portion for user input, a state switching portion to change the display medium's state between movable and immovable, and a viewpoint switching portion to adjust the camera viewpoint based on user input, allowing for dynamic positioning and viewing modes.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If the viewpoint of the virtual camera is fixed and linked to the avatar, then the system structure is simple, but it becomes difficult to effectively support various user activities such as movement operations and dialog in the virtual space
Solution Approach 1:
The patent implements dynamic viewpoint switching by introducing a state switching portion that changes the display medium's state between movable and immovable based on user input. When the display medium is in the movable state, the viewpoint follows the avatar; when in the immovable state, the viewpoint remains fixed. This dynamic adjustment allows the system to adapt to different user activities (movement operations vs. dialog) without requiring a completely complex multi-camera system, thus resolving the contradiction between adaptability and device complexity.
2Adaptability or versatility
If the display medium position is fixed, then the system is stable and simple to control, but it cannot adapt to different user activities requiring different positioning
Solution Approach 1:
The patent makes the display medium position dynamic by introducing a state switching portion that allows the display medium to transition between movable and immovable states based on user input. This dynamic control mechanism enables the system to adapt to different activities (movement operations requiring position changes vs. dialog requiring stable positioning) while maintaining simple control through a unified switching interface, thus resolving the contradiction between adaptability and ease of operation.
3Adaptability or versatility
If the viewpoint switches between first and third person perspectives, then various activities are better supported, but the system complexity increases
Solution Approach 1:
The patent implements dynamic viewpoint switching by linking the viewpoint mode to the state of the display medium. When the display medium is movable, the system uses third-person perspective; when immovable, it switches to first-person perspective. This dynamic linkage allows the system to provide viewpoint flexibility needed for various activities without requiring a complex independent viewpoint control system, as the viewpoint automatically adapts based on the display medium state.

AI summary
An information processing system includes a drawing portion that draws a display image for a terminal including one or more display media positioned in a virtual space; an acquisition portion that acquires input from a user; a state switching portion that switches, between a plurality of states, a state of the display medium; a position changing portion that changes the position of the display medium associated with one user in the virtual space, based on a first input from the one user acquired by the acquisition portion when the state of the display medium is a first state; and a viewpoint switching portion that switches a viewpoint of when the drawing portion draws the display image from a first viewpoint to a second viewpoint when the state of the display medium is switched from the first state to a second state by the state switching portion.
