Social Robot Sensor Feedback for Dynamic Interaction Adaptation
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current social robots require manual input for user profiling, which is time-consuming and disrupts interactions, failing to adapt effectively to individual human characteristics and preferences during social interactions.
Innovation Solution
A social robot system that uses sensors to identify human characteristics, generates and adapts dialog and motion scripts based on real-time feedback, allowing for personalized and continuous improvement of interactions without manual input, and logs adjustments for future use.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Measurement precision
If manual input for user profiling is used, then the robot can obtain user characteristics, but the process is time-consuming and disrupts interactions
Solution Approach 1:
The robot performs user profiling automatically without requiring manual input from users. Sensors continuously collect data about user characteristics and preferences, and the system self-updates its interaction models based on this data, eliminating the need for time-consuming manual profiling processes
Solution Approach 2:
The system continuously monitors user reactions during interactions and uses this feedback to dynamically update user profiles and adjust interaction strategies. This real-time feedback loop allows the robot to refine its understanding of user characteristics without interrupting the interaction flow
2Adaptability or versatility
If the robot adapts to individual human characteristics, then interaction quality improves, but the system complexity increases
Solution Approach 1:
The robot employs dynamic interaction scripts that can be modified in real-time based on sensed user characteristics and reactions. Rather than requiring complex pre-programming for every scenario, the system dynamically adjusts its behavior and dialog based on current sensor inputs and updated user profiles
Solution Approach 2:
A unified sensor system and processing framework handles multiple types of user characteristics and interaction scenarios. The same core architecture processes diverse sensor data and applies general adaptation rules across different interaction contexts, reducing overall system complexity while maintaining high adaptability
3Productivity
If real-time sensor analysis is performed, then interaction adaptation is continuous, but processing requirements increase
Solution Approach 1:
The system performs selective analysis of sensor data, focusing computational resources on the most relevant characteristics and reactions that impact interaction quality. Rather than processing all sensor data equally, the system identifies and prioritizes key signals for analysis, reducing overall processing requirements while maintaining effective adaptation

AI summary
A method of optimizing social interaction between a robot and a human. The method comprises generating then executing a robot motion script for interaction with a human by a robot based on a characteristic detected by at least one of a plurality of sensors on the robot. The method further comprises detection, by at least one sensor of the robot, a reaction of the human during a first period. The robot then analyzes the reaction of the human and assigns a positive or negative classification to the reaction based on pre-defined mapping stored in the memory of the robot. The method further comprises modifying the robot motion script to incorporate a pre-defined modification based on the determination of a negative classification of the human reaction. The method further comprises executing the modified robot motion script during a second period to obtain an improved interaction with the human.
