Touch Screen Virtual Wheel for Spinning Bar Control
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing video game interfaces lack intuitive control over rotational movements, such as gymnastics, due to indirect user interaction methods like joysticks, which can result in a less satisfying gameplay experience.
Innovation Solution
A touch screen interface using 3D computer graphics to model a spinning bar, where players control the rotation and acrobatic moves of a game character by manipulating a virtual wheel with stylus strokes, allowing direct control over the bar's spin speed and character movements.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If a joystick or traditional game controller is used to control gymnastic moves, then the device complexity is reduced, but the ease of operation deteriorates due to indirect control and lack of intuitive response
Solution Approach 1:
The patent introduces a virtual wheel as an intermediary control element displayed on the touch screen. This virtual wheel serves as a mediator between the user's touch input and the gymnastic character's rotational movements, providing intuitive control while maintaining the simplicity of the touch screen interface.
Solution Approach 2:
The patent replaces the traditional mechanical joystick control system with a touch screen-based virtual wheel interface. This substitution eliminates the need for physical buttons and sticks, providing more intuitive control through direct touch interaction while reducing overall device complexity.
2Ease of operation
If a touch screen interface with virtual wheel is implemented, then the ease of operation improves through direct control, but the device complexity increases due to additional interface elements
Solution Approach 1:
The virtual wheel interface serves multiple functions: it controls the spinning bar rotation, enables character movement selection, and provides intuitive touch-based interaction. By making the interface element multi-functional, the patent reduces the need for separate controls for each function, thereby managing complexity while improving ease of operation.
Solution Approach 2:
The patent transitions from traditional 2D joystick control to a 3D touch screen interface with virtual wheel elements. This dimensional change allows for more intuitive control through natural touch gestures while managing complexity through the integrated nature of the virtual interface.
3Reliability
If physics modeling is made more realistic for gymnastic movements, then the authenticity of gameplay improves, but the device complexity increases due to more complicated calculations
Solution Approach 1:
The patent implements feedback mechanisms where the virtual wheel's visual rotation state provides real-time feedback to the user about the spinning bar's current rotation. This feedback system enhances the authenticity of the physics simulation by providing intuitive visual cues while managing calculation complexity through efficient rendering techniques.
Solution Approach 2:
The patent dynamically adjusts physics parameters such as rotation speed, gravity, and friction based on user input through the virtual wheel. By changing parameters in response to user actions rather than using fixed complex calculations, the system achieves realistic physics simulation while managing computational complexity.
Data Source
AI summary
The video or other computer graphics display shows, on a touch screen, a spinnable bar having a control wheel affixed to an end thereof. Strokes of a stylus applied to the surface of the wheel controls the direction and/or rate of spin of the wheel and bar. An animated game character holding on to the spinning bar may spin with the bar and perform acrobatic acts in response to other touch screen or other types of control inputs.
