Head-wearing Device Sound Notification via Amplitude Difference Detection
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Closed design head-wearing devices isolate users from external information, making it difficult for them to receive notifications or external inputs while wearing the device.
Innovation Solution
A method and device that use multiple microphones to collect sound signals, process them to detect amplitude differences, and generate notifications when these differences exceed a threshold, allowing users to be alerted to external information without compromising the device's seal.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If closed design is adopted for head-wearing devices to isolate users from outside, then immersive experience is improved, but ability to receive external information deteriorates
Solution Approach 1:
The device divides sound signal processing into multiple independent channels, each handled by separate microphones and processing circuits. This segmentation allows the system to maintain the closed structure while processing external sound signals through dedicated pathways, enabling notification functionality without compromising the immersive seal.
Solution Approach 2:
The patent introduces an intermediary notification mechanism that bridges the closed immersive environment and external information. The processing circuitry acts as an intermediary, detecting amplitude differences in external sounds and converting them into notification signals (visual, auditory, or haptic) that can alert users to external information without breaking the physical seal of the device.
2Loss of information
If multiple microphones and processing circuitry are added to detect external sounds, then ability to receive notifications is improved, but device complexity increases
Solution Approach 1:
The notification processing circuitry is designed to perform multiple functions: it processes sound signals from multiple microphones, calculates amplitude differences, determines notification triggers, and controls various notification output methods (visual, auditory, haptic). This multi-functionality reduces the need for separate dedicated circuits for each function, thereby managing complexity while achieving comprehensive external information detection.

AI summary
A method and a device for information processing are provided. A plurality of sound signals are collected via a plurality of microphones. Next, a combined sound signal for each of at least one pair of the plurality of sound signals is generated by processing circuitry of the information processing device. Each combined sound signal is a combination of a respective pair of the plurality of sound signals. Further, an amplitude difference between the sound signals of each of the at least one pair of the plurality of sound signals is calculated by the processing circuitry. The amplitude difference between the sound signals of each of the at least one pair of the plurality of sound signals is compared with a preset threshold value. A notification message is accordingly generated when the amplitude difference between the sound signals of one or more of the at least one pair of the plurality of sound signals is greater than or equal to the preset threshold value based on the comparison. Subsequently, the notification message is output by the processing circuitry for presentation to a user.
