Wearable Attraction Display Layout for Selective Voice Capture
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing interactive attraction systems struggle with identifying and responding to the correct audio inputs from guests due to interference from multiple audio sources, leading to undesirable operations and inconsistent guest experiences.
Innovation Solution
The system employs interactive devices with a display and microphone positioned at oblique angles to project images and receive audio waves deflecting off the display, blocking unwanted audio inputs and focusing on desired inputs from the associated guest, using a control system to filter and process audio data effectively.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Measurement precision
If the microphone is positioned to receive audio waves directly from the guest, then the audio input detection is straightforward, but unwanted audio inputs from multiple sources interfere with the detection accuracy
Solution Approach 1:
The display serves as an intermediary surface between the guest and the microphone. Audio waves from the guest deflect off the display before reaching the microphone, while the display blocks direct paths from other audio sources to the microphone. This mediator configuration enables selective audio reception.
Solution Approach 2:
The system transitions from direct linear audio reception to indirect angular audio reception via the display surface. By positioning the microphone at an oblique angle relative to the display, the system captures audio waves that have traveled through a different spatial dimension (reflecting off the display surface), thereby separating the desired audio path from interfering paths.
2Reliability
If the projector and microphone are positioned at oblique angles to the display, then the desired audio and image functions are achieved, but the device structure becomes more complex
Solution Approach 1:
The projector, display, and microphone are merged into a single integrated interactive device unit. The projector and microphone are positioned relative to the display within the same device housing, combining multiple functions (image projection, audio reception, and blocking) into one unified structure that reduces overall system complexity.
Solution Approach 2:
The display surface serves multiple functions simultaneously: it acts as the projection screen for visual output, a reflective surface for audio wave deflection, and a blocking barrier for unwanted audio inputs. This multi-functionality reduces the need for separate components and simplifies the overall device architecture.
