Dynamic Sound Mode Control for Natural State Feedback
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing sound output systems for apparatuses, such as robots, often produce unnatural sounds when transitioning from a normal state to a different state, leading to user discomfort due to the use of special beeps or alerts that do not align with the apparatus's concept, making the experience unnatural and potentially uncomfortable.
Innovation Solution
An information processing apparatus with a controller that dynamically changes the mode of synthetic sound output based on the detected state of the apparatus, using parameters like timbre, tone, and acoustic pressure to create a more natural and intuitive sound output, allowing the user to perceive the apparatus's state more naturally.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If a different type of sound is output based on detection of a given state, then the apparatus can indicate state changes, but the sound may sound unnatural and cause user discomfort
Solution Approach 1:
The patent applies parameter changes by dynamically adjusting sound output parameters (mode, volume, type) based on the detected state and amount of change. Instead of using fixed different-type sounds for state changes, the system modifies parameters of the normal synthetic sound to create natural transitions that indicate state changes without causing user discomfort.
Solution Approach 2:
The system implements dynamics by making the sound output adaptive and variable based on real-time state detection. The controller dynamically selects and modifies sound parameters according to the current state and the magnitude of state change, creating a flexible sound output system that responds naturally to different operating conditions.
2Loss of information
If special beeps or alerts are used to indicate state changes, then the state can be clearly communicated, but the experience becomes unnatural and potentially uncomfortable
Solution Approach 1:
The patent modifies sound parameters (mode, volume, characteristics) of the normal synthetic sound based on the detected state and amount of change. This allows state information to be communicated through natural variations in the existing sound rather than switching to artificial beeps or alerts, maintaining user experience naturalness while ensuring clear state communication.
3Loss of information
If the apparatus outputs different sounds for different states, then state information is conveyed, but the interaction becomes less natural and appealing
Solution Approach 1:
The system uses dynamic parameter adjustment of the normal synthetic sound based on real-time state detection. The controller adapts the sound output characteristics according to the current state and amount of change, creating a versatile and natural interaction experience that conveys state information without breaking the naturalness of the apparatus concept.
