Pointing Device Control for Complex Game Interactions
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional game systems using optical pointing devices, such as gun type controllers, are limited to simple operations like indicating positions on a screen, leading to a lack of amusement and complexity in games.
Innovation Solution
A game program and apparatus that utilize a pointing device to detect positions and control objects in a virtual game space, allowing for more complex interactions by determining object indications, operation states, and controlling processing related to indicated objects, enhancing gameplay experience.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If a conventional gun type controller with CCD camera is used to detect position on screen, then position indication is achieved, but the operation remains simple and lacks amusement
Solution Approach 1:
The pointing device is enhanced with multiple input means (imaging means, acceleration sensing means, operation means) that enable diverse operations beyond simple position indication. The device can perform position indication, acceleration detection, and various game operations, making it a multi-functional controller that increases game versatility and amusement.
2Device complexity
If only position indication function is provided in the pointing device, then the device structure remains simple, but the game content and operation become too simple
Solution Approach 1:
The pointing device is divided into distinct functional modules: imaging means (CCD camera) for position detection, acceleration sensing means for motion detection, and operation means (buttons) for command input. This segmentation allows each component to contribute to game operations independently, enabling complex gameplay while maintaining a manageable device structure.
Solution Approach 2:
The device transitions from two-dimensional screen position indication to three-dimensional spatial awareness by incorporating acceleration sensing means that detect motion in multiple directions. This adds a temporal and spatial dimension to game operations, allowing players to perform actions based on both position and motion dynamics.
Data Source
AI summary
A video game apparatus includes a CPU, the CPU detects marker coordinates data included in input data transmitted from a controller, and calculates indicated coordinates of the controller. A star object indicated by the controller is set as a target object by a player pressing a B-trigger switch. Then, a player object executes a processing according to the target object. For example, when the player continues to press the B-trigger switch, the player object is moved to approach the target object.
