Wearable Attraction Interface for Display-Reflected Voice Input
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing attraction systems face challenges in accurately identifying and responding to guest interactions due to interference from unwanted audio inputs, leading to undesirable system operations.
Innovation Solution
The interactive device is designed with a display and microphone positioned at oblique angles to project images and receive audio waves deflecting off the display, respectively, while blocking unwanted audio inputs, and a control system filters and processes audio inputs to ensure accurate operation based on the intended user's input.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Measurement precision
If the microphone is positioned to receive audio waves directly from the user, then the audio input accuracy is improved, but the system is more susceptible to interference from unwanted audio sources
Solution Approach 1:
The display surface acts as an intermediary element between the user's voice and the microphone. Audio waves from the user deflect off the display surface before reaching the microphone, while the display simultaneously blocks direct paths for unwanted audio sources to reach the microphone, thus filtering inputs spatially
Solution Approach 2:
The system transitions from direct linear audio capture to indirect audio capture via the display surface at oblique angles. This dimensional change in audio wave path allows the display to function both as a visual output and an acoustic mediator, creating a spatial filter that distinguishes user input from background noise
2Object-affected harmful factors
If the projector and microphone are positioned at oblique angles with respect to the display, then the display can block unwanted audio inputs, but the device complexity increases
Solution Approach 1:
The patent merges the display function with the audio input mediation function. The display surface serves dual purposes: presenting visual content and acting as a reflector for audio waves from the user to the microphone, while simultaneously blocking unwanted audio sources. This integration reduces the need for additional separate acoustic components
Solution Approach 2:
The display component is designed to perform multiple functions: visual output display, audio wave reflection surface, and acoustic barrier. This multi-functionality eliminates the need for separate dedicated components for each function, thereby reducing overall device complexity while achieving the desired audio filtering effect
