Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing techniques fail to allow users to perceive a pseudo haptic sense without performing a complicated physical operation or using a haptic sense based on a physical reaction to a human body motion.
Innovation Solution
A visual object is visually changed by a magnitude of visual change based on a motion of a body part, with the relationship between the magnitude of visual change and manipulation amount defined to present a pseudo haptic sense.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If visual feedback is manipulated based on haptic input device information, then pseudo haptic sense can be presented to user, but user must perform complicated physical operation to simulate real environment
Solution Approach 1:
The patent replaces the mechanical input system (haptic input devices requiring physical manipulation) with a camera-based vision system that detects hand gestures and body movements. The image processing unit analyzes visual data to determine manipulation amounts, substituting mechanical interaction with optical detection and computational analysis, thereby eliminating the need for complicated physical operations while maintaining pseudo haptic feedback functionality
Solution Approach 2:
The patent introduces an image processing unit as an intermediary between the user's natural hand movements and the visual feedback system. This intermediary captures raw visual data, processes it to extract manipulation information, and translates natural gestures into control signals, serving as a mediator that converts simple physical movements into meaningful input commands without requiring users to learn complex操作 protocols
2Reliability
If visual feedback delay or fluctuation is applied, then pseudo haptic impression can be given to user, but cannot present pseudo haptic sense without physical reaction to human body motion
Solution Approach 1:
The patent substitutes the mechanical reaction force system with a vision-based detection system. Instead of using force feedback devices that physically react to user movements, the system uses camera imaging to detect hand and body movements, processes the visual information to determine manipulation amounts, and applies appropriate visual feedback delays or fluctuations to create pseudo haptic sensations without requiring complex physical reaction mechanisms
Solution Approach 2:
The patent creates a visual copy of the user's hand movements and body gestures through camera imaging. The image processing unit generates a digital representation of the natural movements, which is then manipulated with delays or fluctuations to produce pseudo haptic effects. This copying approach allows the system to simulate physical reactions without actually implementing complex mechanical reaction systems

AI summary
A visual object is visually changed by a magnitude of visual change of the visual object according to a manipulation based on a motion of a body part on the basis of manipulation information indicating the manipulation and information indicating a relationship between the magnitude of visual change and a manipulation amount based on the manipulation, and information for presenting the visually changed visual object is output. Here, this relationship is defined at least according to an index representing a degree of a pseudo haptic sense to be presented.
