Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing remote communication technologies face challenges in aligning sight lines between users, making it difficult to achieve smooth communication as they rely on quantitative changes in eye direction, which are not easily quantifiable.
Innovation Solution
An information processing apparatus and method that includes a receiver unit, face detection unit, and superimposition unit to acquire and display the sight line position of a communication partner, allowing for precise alignment of sight lines by detecting face position and size from video signals and superimposing a marker indicating the sight line position.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Measurement precision
If quantitative changes in eye direction are used to align sight lines, then sight line alignment can be achieved, but it becomes difficult to completely align sight lines because eye direction is not easily quantifiable
Solution Approach 1:
The patent replaces the mechanical/physical method of adjusting eye direction with an information processing system that detects face positions and calculates sight line directions using video signals and coordinate transformations. This substitution allows for precise digital measurement and adjustment of sight lines without requiring physical eye movement quantification.
Solution Approach 2:
The patent introduces an intermediary information processing apparatus that acts as a mediator between the two communication terminals. This intermediary calculates sight line directions, performs coordinate transformations, and provides alignment instructions, thereby simplifying the alignment process for users while achieving precise sight line alignment.
2Productivity
If sight line alignment technology is implemented, then communication smoothness is improved, but the system complexity increases due to the need for face detection and coordinate transformation
Solution Approach 1:
The information processing apparatus performs multiple functions including face detection, sight line direction calculation, coordinate transformation, and alignment instruction generation. By consolidating these functions into a single multi-functional system, the patent reduces overall system complexity compared to having separate systems for each function.
Solution Approach 2:
The system automatically detects face positions, calculates sight line directions, and generates alignment instructions without requiring manual user input or configuration. This self-service capability reduces the operational complexity for users while maintaining high communication smoothness.
