Guide Robot Route Control Using User Reaction Feedback
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Users guided by conventional guidance systems may feel their movement is restricted, leading to stress due to the robot's control over their path, without consideration for individual needs or preferences.
Innovation Solution
A guide robot control device that determines a route based on user dynamic data, estimates guidance requests, and adjusts the route dynamically by inquiring about the necessity of changes, ensuring the route aligns with the user's intentions and preferences, while respecting their stress levels.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Measurement precision
If the robot controls the user's movement path strictly, then guidance accuracy is improved, but user stress increases due to restricted movement
Solution Approach 1:
The system dynamically adjusts the guidance route based on real-time recognition of user reactions. The route determination unit modifies the path when the recognition unit detects user stress or negative reactions, transforming the static rigid route into a dynamic adaptive path that balances guidance accuracy with user comfort
Solution Approach 2:
The system implements a feedback loop where the recognition unit continuously monitors user reactions (facial expressions, body language) and feeds this information back to the route determination unit. This closed-loop control allows the system to adjust the guidance route in response to user stress, resolving the contradiction between maintaining guidance accuracy and reducing user stress
2Adaptability or versatility
If the system adjusts the route based on estimated user requests, then user satisfaction is improved, but system complexity increases
Solution Approach 1:
The recognition unit acts as an intermediary that translates complex user reactions and implicit requests into simplified guidance parameters. This intermediary layer processes facial expressions and body language to estimate user requests, enabling the system to adapt to user needs without requiring direct complex communication, thus improving user satisfaction while managing system complexity
Solution Approach 2:
The system estimates user requests automatically by analyzing user reactions without requiring explicit user input. The guidance request estimation unit infers user needs from observed behavior, allowing the system to self-adjust the route based on estimated requests, improving adaptability while avoiding the complexity of continuous direct user communication
Data Source
AI summary
A server (3) includes a route determination unit (3f1) that determines a route; a user dynamic data recognition unit (3a1) that recognizes, during guidance, user dynamic data; a guidance request estimation unit (3c) that estimates a guidance request of a user, based on the user dynamic data; a notification instruction unit (3h) that issues to a robot (2) an instruction for notification of inquiry information for inquiring about necessity of change of the route; and a reaction recognition unit (3i) that recognizes a reaction of the user to the notification. The route determination unit (3f1) determines a content of the change of the route, based on the guidance request, and determines whether the change of the route is performed, based on the reaction.
