Solution Overview

Problem

Current projected user interfaces do not adapt to the physical properties of the surface onto which they are projected, such as color, texture, deformability, and hardness, resulting in a lack of cohesion and an inconsistent user experience.

Innovation Solution

A method and system that determine the properties of the surface using sensors and cameras, and adjust the projected user interface settings to harmonize with these properties, including animations and sound effects, to create a more cohesive and responsive interaction experience.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Adaptability or versatility

If the same user interface is projected in the same way regardless of surface properties, then the system is simple and easy to implement, but the user experience is inconsistent and lacks cohesion

Engineering Contradiction:

ImproveAdaptability of projected user interface to surface propertiesVSAvoidComplexity of adapting user interface to surface properties

Core Design Contradiction:

Adaptability or versatilityVSDevice complexity

Solution Approach 1:

The projected user interface dynamically adapts its properties based on real-time detection of surface characteristics. The system modifies animation behaviors, sound effects, and visual parameters according to the detected surface type (e.g., hard vs. soft surfaces, different colors), transforming a static projection system into a dynamic one that responds to environmental conditions.

Inventive Principle:

Principle #15Dynamics

Solution Approach 2:

The system changes multiple parameters of the projected user interface based on surface properties. This includes adjusting animation duration and intensity, modifying sound effect characteristics, and altering visual contrast and color parameters to harmonize with the detected surface, thereby achieving adaptability through parameter modification.

Inventive Principle:

Principle #35Parameter changes

2Ease of operation

If the projected user interface is adapted to match surface properties, then the user experience becomes more cohesive and intuitive, but the system complexity increases

Engineering Contradiction:

ImproveIntuitiveness of user interaction with projected interfaceVSAvoidComplexity of surface property detection and adaptation system

Core Design Contradiction:

Ease of operationVSDevice complexity

Solution Approach 1:

The system performs self-service by automatically detecting surface properties and adjusting its own projection parameters without requiring manual user configuration. The device autonomously analyzes the surface characteristics and selects appropriate animation and sound parameters, making the complex adaptation process transparent to the user and maintaining ease of operation.

Inventive Principle:

Principle #25Self-service

Solution Approach 2:

The system implements feedback by continuously monitoring surface properties and using this information to adjust the projected user interface in real-time. The detection of surface characteristics feeds back into the projection system, which then modifies its behavior accordingly, creating a closed-loop system that enhances intuitiveness through responsive adaptation.

Inventive Principle:

Principle #23Feedback

3Reliability

If animations and sound effects are customized to match surface properties, then the user experience becomes more immersive, but the processing requirements and energy consumption increase

Engineering Contradiction:

ImproveConsistency of user experience across different surfacesVSAvoidEnergy consumption for real-time adaptation and customization

Core Design Contradiction:

ReliabilityVSUse of energy by moving object

Solution Approach 1:

The system applies local quality by customizing specific aspects of the user interface (animations and sound effects) based on local surface properties rather than uniformly changing all parameters. Different surface characteristics trigger specific adaptation rules for particular UI elements, allowing targeted customization that maintains reliability while managing energy consumption through selective modification.

Inventive Principle:

Principle #3Local quality

4Adaptability or versatility

If the system detects surface properties in real-time during user interaction, then the adaptability is maximized, but the measurement and processing complexity increases

Engineering Contradiction:

ImproveReal-time adaptability during user interactionVSAvoidDifficulty of detecting surface properties during interaction

Core Design Contradiction:

Adaptability or versatilityVSDifficulty of detecting and measuring

Solution Approach 1:

The system performs preliminary detection of surface properties before full user interaction begins. By analyzing the surface characteristics in advance, the system prepares appropriate adaptation parameters and settings, reducing the complexity of real-time detection during actual user interaction while maintaining real-time adaptability through pre-computed adjustment rules.

Inventive Principle:
