Autonomous Mobile Body Control Using Dual-Sensor User Interaction
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current agent devices that respond to user actions primarily focus on information presentation and lack effective communication, with passive operations that do not actively engage users, resulting in insufficient interaction.
Innovation Solution
An information processing apparatus with a first sensor and a second sensor, along with an operation control unit, that detects objects and controls the autonomous mobile body's operations to induce communication with users through active actions and physical interactions, such as movement and voice messages, enhancing user engagement.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Productivity
If an agent device focuses on information presentation to respond to user actions, then information delivery efficiency is improved, but communication effectiveness with users deteriorates
Solution Approach 1:
The autonomous mobile body dynamically changes its physical state by moving toward the user or approaching objects of interest, transforming from a static information display device to an active communication partner. This dynamic movement enhances communication effectiveness while maintaining efficient information delivery through coordinated action with the display unit.
Solution Approach 2:
The autonomous mobile body acts as an intermediary between the user and the information environment. By physically moving to interact with objects and presenting information about them, it mediates the user's understanding of the environment, thereby improving communication effectiveness without sacrificing information delivery efficiency.
2Device complexity
If an agent device performs passive operations to respond to user actions, then device complexity is reduced, but user engagement deteriorates
Solution Approach 1:
The autonomous mobile body autonomously determines when and where to move based on detected objects and user position, without requiring complex user commands. This self-service capability enables active user engagement while keeping the control system relatively simple, as the device independently decides its own actions based on sensor input.
Solution Approach 2:
The autonomous mobile body integrates multiple functions including object detection, user tracking, autonomous navigation, and information presentation in a single device. This multi-functionality enables diverse user engagement scenarios without proportionally increasing device complexity, as all functions are coordinated through a unified control system.
3Device complexity
If a single sensor system is used to detect objects, then device complexity is reduced, but detection reliability deteriorates
Solution Approach 1:
The invention combines multiple sensor systems (camera and imaging sensor) with different detection principles into a unified object detection system. The camera captures visual information while the imaging sensor detects reflected light patterns, and their results are integrated to achieve reliable object detection and identification, overcoming the limitations of using either sensor alone.

AI summary
An information processing apparatus includes a first sensor, a second sensor, and a central processing unit (CPU). The first sensor detects an object present in a first direction with respect to an autonomous mobile body. The second sensor detects the object present in a second direction with respect to the autonomous mobile body, by a system different from a system of the first sensor. The CPU controls an operation of the autonomous mobile body based on a detection result acquired by the first sensor and a detection result acquired by the second sensor.
