Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing emotional self-reporting technologies lack consistency and reliability in assessing and reporting human emotional states, particularly in psychological and human-computer interaction applications.
Innovation Solution
A method and apparatus utilizing a three-dimensional PAD model to explore and represent emotional states using X, Y, and Z axes, with axes representing pleasure, arousal, and dominance, and outputting facial expressions or colors in real time based on integrated coordinate values ranging from -1 to +1.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If traditional emotional self-reporting methods are used, then the process is simple, but the consistency and reliability of emotional assessment are poor
Solution Approach 1:
The patent applies dimensionality change by transitioning from traditional one-dimensional or two-dimensional emotion representation to a three-dimensional PAD model space. The emotional state is represented using three axes (Pleasure, Arousal, Dominance) with coordinate values ranging from -1 to +1, enabling more precise and reliable emotional assessment while maintaining systematic structure
Solution Approach 2:
The patent changes the parameters of emotional representation by using continuous coordinate values (-1 to +1) for each PAD dimension rather than discrete categories. This parameter transformation allows for finer-grained emotional differentiation and improves the reliability of self-reporting while keeping the system manageable through standardized parameter ranges
2Measurement precision
If detailed emotional state representation is implemented, then the accuracy of emotional assessment improves, but the complexity of the system increases
Solution Approach 1:
The patent achieves accurate emotional state assessment by transforming emotional parameters into continuous coordinate values within standardized ranges (-1 to +1) for each PAD dimension. This parameter standardization enables precise measurement while maintaining system manageability through consistent parameter formats
Solution Approach 2:
The patent segments the complex emotional state into three independent dimensional components (Pleasure, Arousal, Dominance), each represented by separate coordinate axes. This segmentation allows for precise measurement of individual emotional dimensions while simplifying the overall system structure through modular representation
3Ease of operation
If real-time emotional output is provided, then the usability and intuitiveness improve, but the processing requirements increase
Solution Approach 1:
The patent enhances usability by mapping emotional state coordinates to color representations, where different colors correspond to different emotional states. This visual transformation provides intuitive real-time feedback without requiring complex processing, as color mapping can be efficiently computed from the PAD coordinate values
Solution Approach 2:
The patent creates intuitive visual copies of emotional states through facial expression representations and color outputs that mirror the internal PAD model coordinates. These visual copies provide immediate, easily interpretable feedback to users while using straightforward transformation algorithms that minimize processing requirements
Data Source
AI summary
A method and apparatus for emotional self-reporting are disclosed. The method includes: continuously exploring an emotional state of a user within a PAD model space defined by X, Y, and Z axes using an input unit; receiving the explored emotional state as respective coordinate values of the of the X, Y, and Z axes; determining a final facial expression or a final emotional color corresponding to the emotional state of the user by integrating the coordinate values of the respective X, Y, and Z axes; and outputting, in real time, one or more of the final facial expression or the final emotional color using an output unit, wherein the X axis represents pleasure, the Y axis represents arousal, and the Z axis represents dominance, and each of the axes represents the emotional state using a scale defined by coordinate values ranging from −1 to +1.
