Emotion-Adaptive Robot Positioning for Comfortable Human Interaction
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current communication robots do not adequately consider psychological stress caused to humans, particularly due to factors like sudden appearance and inappropriate spatial orientation, which can lead to discomfort or stress, despite advancements in maintaining personal space and emotional understanding.
Innovation Solution
A mobile body control system that includes a moving unit, a measuring unit for angle and distance, an emotion estimating unit, and a control unit to adjust the robot's position to an appropriate angle and distance based on the estimated emotion of the communication target, ensuring comfortable interaction without causing stress.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Object-affected harmful factors
If a robot maintains a fixed distance with a communication target, then personal space is secured, but psychological stress is not adequately considered due to lack of angle adjustment
Solution Approach 1:
The robot dynamically adjusts both distance and angle based on real-time emotion recognition. The control unit modifies positioning parameters continuously during communication, transitioning from static fixed-distance positioning to dynamic multi-dimensional positioning that adapts to emotional states, thereby reducing psychological stress while maintaining appropriate personal space
Solution Approach 2:
The system changes spatial parameters (distance and angle) based on emotional parameters. When the communication target exhibits stress or negative emotions, the robot adjusts its positioning parameters to optimize comfort, creating a mapping between emotional state and spatial configuration that resolves the contradiction between maintaining personal space and reducing psychological stress
2Productivity
If a robot suddenly appears in front of a person to initiate communication, then communication efficiency is improved, but it causes psychological stress and discomfort
Solution Approach 1:
The robot performs preliminary positioning actions by approaching from the side at an angled position before establishing face-to-face communication. This preliminary angled approach allows the communication target to gradually acclimate to the robot's presence, reducing sudden appearance shock while maintaining communication efficiency through progressive engagement
Solution Approach 2:
The robot anticipates potential stress from sudden appearance by taking counter-actions in the form of angled positioning and gradual approach. This preliminary anti-action prevents the harmful effect of sudden appearance by offsetting it with a more gradual, less intrusive entry into the communication target's personal space
3Object-affected harmful factors
If a robot uses only distance control to manage personal space, then implementation is simple, but it cannot adequately address psychological influences from different spatial orientations
Solution Approach 1:
The control unit performs multiple functions by integrating both distance control and angle control in a single positioning system. This multi-functional approach allows the robot to manage both personal space (distance) and psychological comfort (angle) through unified control logic, addressing psychological influences without proportionally increasing system complexity
