Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If traditional triggered haptic feedback architecture is used, then the system structure is simple, but the haptic feedback timing is static and inconsistent leading to poor user experience
Solution Approach 1:
The patent implements dynamic haptic feedback by continuously adjusting haptic parameters based on real-time gesture signals and sensor data rather than using static triggered feedback. The system dynamically modifies vibration intensity, frequency, and pattern according to the current interaction state, resolving the contradiction between feedback consistency and system complexity.
Solution Approach 2:
The system incorporates multiple feedback loops that continuously monitor gesture signals, sensor data, and haptic output to adjust haptic parameters in real-time. This feedback mechanism ensures consistent and adaptive haptic feedback while managing system complexity through structured control architecture.
2Adaptability or versatility
If haptic feedback is provided without integrating device sensor information, then the system implementation is simple, but the haptic feedback lacks dynamic adaptation to user context
Solution Approach 1:
The patent merges multiple input sources including gesture signals from touch screens, data from accelerometers, gyroscopes, and other sensors into a unified haptic control system. This integration enables context-aware adaptive haptic feedback while managing complexity through modular signal processing architecture.
Solution Approach 2:
The system creates a universal haptic control framework that can process and integrate various types of input signals (touch gestures, motion sensors, environmental sensors) through a common processing pipeline, enabling adaptive haptic feedback across diverse usage scenarios without proportionally increasing complexity.
3Adaptability or versatility
If haptic feedback is provided without combining multiple gesture signals and sensor signals, then the processing complexity is low, but the haptic effect is static and less compelling
Solution Approach 1:
The system generates dynamic haptic effects by continuously processing combinations of gesture signals and sensor signals to adjust vibration parameters in real-time. The haptic feedback adapts to the dynamics of user interaction, creating more compelling and context-relevant tactile experiences while managing processing complexity through efficient signal integration.
Data Source
AI summary
A system that produces a dynamic haptic effect and generates a drive signal that includes a gesture signal and a real or virtual device sensor signal. The haptic effect is modified dynamically based on both the gesture signal and the real or virtual device sensor signal such as from an accelerometer or gyroscope, or by a signal created from processing data such as still images, video or sound. The haptic effect may optionally be modified dynamically by using the gesture signal and the real or virtual device sensor signal and a physical model, or may optionally be applied concurrently to multiple devices which are connected via a communication link. The haptic effect may optionally be encoded into a data file on a first device. The data file is then communicated to a second device and the haptic effect is read from the data file and applied to the second device.
