Parallel Reality Elevator Display for Personalized Passenger Information
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing elevator systems lack an efficient and convenient method to provide passengers with information about their assigned elevator car and intended destinations, particularly in systems that use destination entry approaches.
Innovation Solution
The implementation of a parallel reality display system with multiple pixels capable of emitting different colors, which simultaneously displays passenger information to multiple individuals from various viewing directions, using location sensors such as cameras and wireless communication devices to determine and provide accurate information about assigned elevator cars and their expected arrival times.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If traditional single-view display systems are used to provide passenger information, then the system structure is simple, but multiple passengers cannot receive personalized information simultaneously and conveniently
Solution Approach 1:
The display system is segmented into multiple independent pixel units, each capable of emitting different colors and displaying different information. This allows the display to be divided into multiple viewing zones, where each zone provides personalized information to a specific passenger based on their location, thereby enabling simultaneous personalized information delivery without requiring separate physical displays for each passenger.
Solution Approach 2:
Different regions of the display emit different colors and show different information tailored to specific passengers. The system determines each passenger's location and assigns specific display regions to them, ensuring that each passenger receives personalized information (such as assigned elevator car and floor) in their own viewing direction, thus improving convenience without increasing overall system complexity.
2Loss of information
If multiple separate displays are provided for each passenger, then each passenger can receive personalized information, but the system cost and complexity increase significantly
Solution Approach 1:
Multiple display functions are merged into a single display device. The display system integrates multiple viewing zones and color emission capabilities into one unified display, allowing it to simultaneously provide personalized information to multiple passengers. This merging approach maintains information accuracy for each passenger while avoiding the complexity and cost of deploying multiple separate display devices.
Solution Approach 2:
The single display device is designed to perform multiple functions: it can display different information to different passengers simultaneously, adapt to various viewing directions, and provide personalized content based on passenger location. This multi-functionality ensures that one display unit can replace what would traditionally require multiple dedicated displays, reducing system complexity while maintaining information accuracy.
3Measurement precision
If location sensors and processing systems are added to provide personalized information, then passenger information accuracy improves, but system complexity and cost increase
Solution Approach 1:
The display system automatically detects passenger locations and assigns appropriate display regions without requiring manual intervention. The system uses sensors to detect passenger positions and autonomously determines which information to display to each passenger, reducing the need for complex manual configuration systems while improving location detection accuracy and information personalization.

AI summary
An illustrative example embodiment of an elevator system includes a display configured to show a plurality of images that are each visible from a respective viewing direction. A processor determines passenger information for each of a plurality of passengers based on at least the passenger's intended destination. The display provides first passenger information for a first passenger to be visible from a first viewing direction that is based on a location of the first passenger relative to the display and second passenger information for a second passenger to be visible from a second viewing direction that is based on a location of the second passenger relative to the display. The second passenger information is different than the first passenger information and the second viewing direction is different than the first viewing direction.
