Ride Guest Face Orientation Detection Without Wearables
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Determining guest orientation within amusement park rides is challenging without wearable devices, which are costly and cumbersome, leading to less personalized show scene feature activations.
Innovation Solution
A system using ride cart orientation data, skeletal tracking, and facial/body image detection, combined with machine learning, to determine guest face orientation and rotation, enabling precise control of show scene features.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Measurement precision
If wearable devices are used to detect guest orientation, then measurement precision is improved, but device complexity and cost increase
Solution Approach 1:
The patent uses ride cart orientation data as an intermediary to infer guest face orientation. Instead of directly measuring guest orientation with complex wearable devices, the system measures cart orientation and uses it as a proxy to determine the likelihood that show scene features are visible to guests, thereby resolving the contradiction between measurement precision and device complexity
Solution Approach 2:
The system creates a simplified model by copying the cart's orientation state to represent guest orientation. Rather than directly tracking guest head and face positions, the system uses the cart's known orientation as a representative copy, eliminating the need for complex wearable sensors while maintaining sufficient accuracy for triggering show scenes
2Adaptability or versatility
If wearable devices are deployed for orientation tracking, then personalized show scene activation is improved, but ease of operation deteriorates
Solution Approach 1:
The system provides personalized show scene activation automatically based on cart orientation data without requiring guests to wear or interact with any devices. The ride system itself serves the function of detecting and responding to guest viewing conditions, eliminating the operational burden on guests while maintaining personalized experience delivery
3Ease of manufacture
If traditional orientation detection methods are used, then implementation cost is reduced, but measurement precision deteriorates
Solution Approach 1:
The system makes the existing ride cart orientation measurement system serve multiple functions: it not only controls ride operation but also provides the data needed for personalized show scene activation. This multi-functionality allows the system to achieve precise face orientation detection capabilities without additional measurement devices, resolving the contradiction between implementation cost and measurement precision
Data Source
AI summary
A ride system includes one or more sensors and a controller. The controller receives, from the one or more sensors, position data indicative of the position of a body and/or face of guest on the ride. Using the position data, the one or more controllers, determine a face direction, face rotation, or both of the guest, independent of sensor observations of the face direction and rotation. One or more features of the ride are controlled based upon the determined face direction and/or face rotation.
