Adjective-Based Haptic Feedback Control for Vibration Customization
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current vibration-based haptic feedback technologies in devices like smartphones and game consoles struggle to allow users to accurately receive desired vibrations and quantify perceptible sensations, as they primarily rely on setting frequency and amplitude without user input for desired sensory experiences.
Innovation Solution
A method and device that generate vibrations using adjectives, determining fundamental frequencies and overlap ratios based on user-input adjectives and their degree values, allowing for customizable vibration sensations by modulating amplitude according to perceived intensity.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Measurement precision
If frequency and amplitude are directly set to generate vibration feedback, then the device can produce vibration, but it is difficult for users to receive desired vibration sensation and predict perceptive properties
Solution Approach 1:
The patent transforms the vibration generation parameters from physical quantities (frequency, amplitude) to perceptual parameters (adjectives with degree values). The control unit converts user-input adjectives into corresponding fundamental frequencies and overlap ratios, enabling users to control vibration sensation through descriptive words rather than technical parameters. This resolves the contradiction by making the system both predictable (through adjective-sensation mapping) and easy to operate (through natural language input).
Solution Approach 2:
The patent introduces adjectives as an intermediary between user intent and physical vibration parameters. The control unit acts as a mediator that translates adjective inputs into frequency and amplitude settings. This intermediary layer allows users to express desired sensations without needing to understand or directly manipulate physical parameters, solving both the predictability and ease of operation issues simultaneously.
2Adaptability or versatility
If multiple adjectives with degree values are used to control vibration, then customization of vibration sensation is improved, but the system complexity increases
Solution Approach 1:
The patent segments the vibration control into independent adjective-processing modules. Each adjective (e.g., roughness, heaviness) is handled separately with its own degree value, and the control unit combines these segmented inputs to generate the final vibration pattern. This segmentation allows high customization capability while keeping the system structure manageable through modular processing.
Solution Approach 2:
The patent establishes predetermined mappings between adjectives and vibration parameters (fundamental frequencies and overlap ratios) before runtime. The control unit has pre-configured relationships stored in memory, so when users input adjectives, the system quickly retrieves and applies the corresponding parameters without complex real-time calculations. This preliminary preparation enables versatility without increasing operational complexity.

AI summary
A method for generating a vibration by a device by using an adjective is provided. The method includes setting at least one fundamental frequency and at least one overlap ratio corresponding to a certain adjective and a degree value of the certain adjective, receiving at least one user input for inputting an adjective and a degree value of the input adjective, and generating at least one vibration corresponding to the input adjective and the degree value of the input adjective based on the setting. The generated at least one vibration has a fundamental frequency and an overlap ratio corresponding to the input adjective and the degree value of the input adjective.
