Robot Operation Sound Control for Concurrent Motion Feedback
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
When multiple motions of an autonomous mobile body are detected simultaneously, the output sounds corresponding to these motions are simultaneously produced, leading to user confusion and a deterioration in user experience.
Innovation Solution
An autonomous mobile body equipped with a recognition unit that identifies its own motions and a sound control unit that manages the output of operation sounds, prioritizing certain sounds over others based on predefined priorities to ensure clarity and enhance user experience.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If multiple operation sounds are simultaneously output corresponding to multiple detected motions, then the robot can express all motions, but the user cannot recognize individual sounds and user experience deteriorates
Solution Approach 1:
The patent segments the simultaneous operation sounds into separate audio channels, allowing each motion type to be represented by a distinct sound channel. This enables the system to maintain multiple motion expressions while preventing sound mixing that would reduce recognition clarity.
Solution Approach 2:
The patent changes audio parameters (volume, panning position, frequency) of operation sounds based on the type and priority of detected motions. By dynamically adjusting these parameters, the system emphasizes important motions while de-emphasizing others, maintaining both versatility and recognition clarity.
2Reliability
If different types of output sounds are output simultaneously for multiple motions, then comprehensive motion feedback is provided, but user experience is deteriorated due to inability to recognize individual sounds
Solution Approach 1:
The patent introduces an audio mixing unit as an intermediary that processes multiple operation sounds before output. This mediator selectively combines or separates sounds based on motion priority and type, ensuring comprehensive feedback while maintaining user experience through controlled sound presentation.
Solution Approach 2:
The patent dynamically adjusts the audio output characteristics based on the current motion state. When multiple motions are detected, the system dynamically changes which sounds are output and at what levels, rather than maintaining a fixed simultaneous output pattern, thereby adapting to different operational contexts.

AI summary
Provided is an autonomous mobile body, an information processing method, and an information processing apparatus capable of improving user experience by an output sound of the autonomous mobile body. The autonomous mobile body includes a recognition unit that recognizes a motion of its own device, and a sound control unit that controls an output sound output from the own device. The sound control unit controls output of a plurality of operation sounds that is the output sound corresponding to a plurality of the motions of the own device, and changes the operation sound in a case where the plurality of motions has been recognized. The present technology can be applied to, for example, a robot.
