Solution Overview

Problem

Existing methods cannot effectively present an apparent force that appears to be applied to a visual object, limiting the ability to simulate tactile sensations in image processing.

Innovation Solution

By vibrating a second presentation visual object with respect to a first presentation visual object, including a vibration component of a specific control frequency, an apparent force is made to appear as if it is applied from the second object to the first object.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Illumination intensity

If image processing is used to increase deformation amount of objects in video, then visual perception of softness is improved, but the ability to present apparent force is insufficient

Engineering Contradiction:

Improvevisual perception of softnessVSAvoidability to present apparent force

Core Design Contradiction:

Illumination intensityVSAdaptability or versatility

Solution Approach 1:

The patent applies mechanical vibration by vibrating a second presentation visual object (such as a finger or tool) with respect to a first presentation visual object at a specific control frequency. This vibration creates the illusion that force is being applied to the first object, thereby presenting apparent force through visual vibration effects rather than actual mechanical force application.

Inventive Principle:

Principle #18Mechanical vibration

Solution Approach 2:

The patent changes visual parameters by controlling the vibration frequency and amplitude of the second presentation visual object. By adjusting these vibration parameters, the system can control the magnitude and characteristics of the apparent force perceived by observers, enabling versatile presentation of different force conditions.

Inventive Principle:

Principle #35Parameter changes

2Measurement precision

If vibration of presentation visual objects is added to present apparent force, then tactile sensation perception is improved, but device complexity increases

Engineering Contradiction:

Improvetactile sensation perceptionVSAvoidsystem complexity

Core Design Contradiction:

Measurement precisionVSDevice complexity

Solution Approach 1:

The patent uses visual copying by displaying videos of presentation visual objects that are vibrating in a controlled manner. Instead of requiring complex haptic feedback devices, the system creates a visual copy or representation of force application through video playback, where the vibration of the presented object in the video conveys the sensation of applied force to observers.

Inventive Principle:

Principle #26Copying
