3D Haptic Input Interface for Realistic Force Feedback Control
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current human-computer interfaces, such as those using mice and keyboards, are inadequate for complex interactions as they lack the sensory feedback necessary for realistic and intuitive control, particularly in applications like gaming where actions like throwing or manipulating objects require more nuanced input and feedback.
Innovation Solution
The development of methods that utilize input devices capable of motion in multiple dimensions and the application of force, allowing for haptic feedback to enhance user interaction by simulating realistic sensations, such as weight and texture, to improve the human-computer interface.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If traditional mouse and keyboard interfaces are used, then device simplicity is maintained, but interaction realism and intuitiveness deteriorate
Solution Approach 1:
The patent implements force feedback mechanisms that provide tactile resistance and sensory information to the user during interaction with virtual objects. This feedback loop allows users to feel the properties of virtual objects (weight, texture, hardness) and receive immediate sensory confirmation of their actions, thereby improving interaction realism without requiring complex manual coordination
Solution Approach 2:
The system creates haptic copies of real-world object properties by generating force feedback patterns that simulate physical characteristics such as weight, friction, and material hardness. This allows virtual objects to be interacted with as if they were physical objects, enhancing realism while keeping the input device itself relatively simple
2Ease of operation
If force feedback devices are added, then interaction intuitiveness is improved, but device complexity increases
Solution Approach 1:
The patent combines force feedback capabilities with standard input device functions into an integrated system. The force feedback mechanism is merged with the existing input device architecture, allowing a single device to serve both as a control input and as a haptic feedback interface, thereby improving intuitiveness while limiting the increase in overall system complexity
Solution Approach 2:
The input device is designed to perform multiple functions: it serves as both a traditional input device for controlling virtual objects and as a force feedback device for providing tactile information. This multi-functionality allows the same device to improve interaction intuitiveness across different task types without requiring separate specialized devices for each function
3Measurement precision
If multi-dimensional motion control is implemented, then throwing precision is improved, but control difficulty increases
Solution Approach 1:
The force feedback device automatically calculates and applies the appropriate force magnitudes and directions based on the user's motion input and the virtual object's properties. The system self-adjusts the feedback parameters to achieve realistic throwing dynamics without requiring the user to manually calculate or coordinate multiple control dimensions, thereby improving precision while maintaining ease of operation
4Loss of information
If haptic feedback is added to manage interface characteristics, then visual bandwidth is freed, but device complexity increases
Solution Approach 1:
The patent replaces visual interface management mechanisms with haptic feedback mechanisms. Instead of requiring visual attention to manage interface characteristics such as object selection, manipulation, and spatial relationships, the system uses force feedback to convey this information tactilely, thereby freeing visual bandwidth for other tasks while using the same input device for both modalities
