Portable Display Virtual Camera Scope Control
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional game systems that use mobile hand-held terminals to control virtual objects based on the attitude and motion of the device limit user interaction, as the positional relationship between the virtual world and the scope changes with image scrolling, leading to monotonous operations and reduced verisimilitude.
Innovation Solution
An information processing program that utilizes a portable display apparatus to control the direction and action of virtual objects and cameras based on the attitude and motion of the device, allowing for varied operations by setting predetermined ranges for object action and camera control, enabling intuitive direction setting and movement control.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If the image is scrolled based on the attitude of the mobile hand-held terminal to place the virtual object in the scope, then the virtual object can be controlled to appear in the scope, but the positional relationship between the virtual world and the scope changes due to image scrolling, leading to monotonous operations and reduced verisimilitude
Solution Approach 1:
The patent applies dynamics by making the scope movable rather than fixed. The scope moves in response to the attitude and motion of the mobile hand-held terminal, allowing the virtual camera to pan and tilt dynamically. This dynamic scope movement maintains the positional relationship between the virtual world and the scope while enabling intuitive control, thereby resolving the contradiction between operational verisimilitude and positional stability.
2Ease of operation
If the scope is fixed at the center of the display screen, then the virtual object can be easily placed in the scope, but the user cannot scroll the image on the basis of the attitude of the mobile hand-held terminal while maintaining the positional relationship between the virtual world and the scope
Solution Approach 1:
The patent merges the functions of image scrolling and scope movement into a single integrated control mechanism. The scope is made movable along with the image scrolling, so that both the virtual camera and the scope respond together to the user's attitude and motion inputs. This merging maintains the positional relationship between the virtual world and the scope while enabling smooth image scrolling control, reducing the apparent complexity of the control mechanism.
3Adaptability or versatility
If the user scrolls the image to view another direction in the virtual world, then the display range can be changed, but the scope moves inevitably, leading to monotonous operations
Solution Approach 1:
The patent applies dynamics by making the scope movable rather than fixed. The scope moves in response to the attitude and motion of the mobile hand-held terminal, allowing the virtual camera to pan and tilt dynamically. This dynamic scope movement maintains the positional relationship between the virtual world and the scope while enabling intuitive control, thereby resolving the contradiction between operational verisimilitude and positional stability.

AI summary
On the basis of data output from a portable display apparatus, it is determined whether or not a direction of a predetermined axis set in the portable display apparatus is included in a predetermined range. When it has been determined that the direction of the predetermined axis is included in the predetermined range, an action of an object placed in a virtual world is controlled in accordance with the direction of the predetermined axis. Further, when the direction of the predetermined axis is included in the predetermined range or present outside the predetermined range, an action of a first virtual camera for generating an image of the virtual world is controlled in accordance with the direction of the predetermined axis. Then, a first image representing the virtual world viewed from the first virtual camera is displayed on the portable display apparatus.
