Computer-Vision Kiosk Tracking With Light and Audio Guidance
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing systems lack efficient and user-friendly methods for object tracking and guidance in kiosks, particularly in environments like supermarkets or warehouses, where objects need to be identified, registered, and tracked with precision and user feedback on operation status is required.
Innovation Solution
A kiosk equipped with computer-vision-based object tracking modules, including cameras and processors, that register and track objects within its field of view, and provide light or audio guidance using projectors or laser apparatuses to notify users of correct operation.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Measurement precision
If computer vision tracking modules with cameras and processors are installed in the kiosk, then object tracking precision and user guidance capability are improved, but device complexity and cost increase
Solution Approach 1:
The system divides the monitoring area into multiple zones using virtual boundaries, allowing independent tracking and analysis of objects in each zone. This segmentation enables the complex tracking task to be broken down into simpler zone-specific operations, managing system complexity while maintaining precision.
Solution Approach 2:
The patent introduces an intermediary processing layer that bridges the camera input and the guidance output. This intermediary layer processes computer vision data, determines object locations and movements, and translates them into actionable guidance signals, thereby managing the complexity between sensing and actuation.
2Ease of operation
If light and audio guidance systems are integrated into the kiosk, then user feedback and operation guidance are improved, but device complexity increases
Solution Approach 1:
The system implements feedback mechanisms where the kiosk provides real-time light and audio signals based on detected object placements. This feedback loop guides users through the correct operations, improving ease of use by providing immediate corrective or confirmatory signals without requiring complex manual intervention.
Solution Approach 2:
The guidance system uses universal signaling methods (light and audio) that can convey multiple types of information through a single integrated framework. This multi-functionality allows the system to provide various guidance messages using the same hardware components, reducing overall system complexity.
3Area of stationary object
If multiple tracking modules are deployed to cover larger areas, then object tracking coverage is improved, but device complexity and coordination requirements increase
Solution Approach 1:
The monitoring area is divided into multiple zones, with each tracking module responsible for specific zone(s). This spatial segmentation allows independent operation of each module while covering a larger total area, reducing the coordination complexity compared to a fully integrated multi-module system.
Solution Approach 2:
Each tracking module operates independently within its designated zone with sufficient coverage capability, rather than requiring all modules to coordinate every action. This partial independence reduces coordination overhead while maintaining comprehensive area coverage.
