Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If vibration effects are designed through code programming in advance, then the vibration feedback effect can be achieved, but the user cannot edit or modify the effects to meet their own requirements
Solution Approach 1:
The system enables users to create and customize vibration effects themselves through gesture-based interaction, eliminating the need for professional programming knowledge. Users can tap, long-press, or swipe on the touchscreen to generate and modify vibration patterns directly, making the system self-serviceable for effect creation.
Solution Approach 2:
The patent replaces traditional code-based vibration design with a gesture-based tactile interface. Instead of programming vibration patterns through code, users interact with the system through natural touch gestures on the touchscreen, which are then translated into corresponding vibration signals by the haptic feedback system.
2Ease of operation
If no vibration effect production tools are available, then the system remains simple, but tactile vibration design becomes a skill mastered by very few professionals
Solution Approach 1:
The touchscreen serves multiple functions: it acts as both the display interface and the control interface for vibration effect creation. The same touchscreen used for general interaction also detects gestures for generating vibration patterns, eliminating the need for separate professional design tools and making vibration effect creation accessible to all users.
Solution Approach 2:
The system introduces a gesture recognition intermediary layer between user input and vibration output. User gestures (tap, long-press, swipe) are detected by the touchscreen and translated into vibration signals through preset rules, serving as an accessible intermediary that bridges casual user interaction and complex vibration effect generation without requiring users to learn programming.
3Ease of operation
If gesture-based real-time vibration signal generation is implemented, then users can easily create personalized tactile effects, but the system complexity increases
Solution Approach 1:
The patent merges the gesture detection functionality and vibration signal generation functionality into a unified processing flow. The touchscreen controller that already detects gestures for interface interaction is extended to also generate vibration signals based on the same gesture data, combining multiple functions into one integrated system rather than adding separate complex subsystems.
Solution Approach 2:
The system uses parameter changes in gesture detection (duration, intensity, position) to control vibration signal parameters (frequency, amplitude, duration). By mapping gesture parameters directly to vibration parameters through preset rules, the system achieves flexible vibration effect creation without requiring complex algorithms, simply changing the interpretation of existing gesture parameters.

AI summary
A method for creating tactile effect in real time through a gesture and a related device includes: acquiring a target graphic file, automatically splitting the target graphic file into tracks, and displaying track parameter of the track; identifying whether the track has the track parameter; detecting an inputted gesture tactile signal in real time, generating a corresponding real-time vibration signal according to a preset rule, synchronously writing the real-time vibration signal as input parameter to track parameter, and simultaneously driving a vibration unit to produce a corresponding vibration feedback effect; and binding all the real-time vibration signals generated within a playback duration of the target graphic file to the target graphic file to form a final vibration signal of the target graphic file. In the method, a user can customize tactile effects for target audio and video files, which is convenient to operate and brings better user experience.
