Camera-Based User Guidance System for Interest-Driven Destination Presentation
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing destination floor registration devices cannot guide users who do not operate ascending/descending facilities in a building based on their interests, as they lack information on users who do not use elevators or similar facilities.
Innovation Solution
A guidance system that uses cameras to specify users, judge their arrival floors, acquire behavior and interest information, and present preferred destinations based on attributes with higher interest levels, even for non-elevator users.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Measurement precision
If destination floor registration uses elevator operation history, then guidance accuracy for elevator users is improved, but guidance capability for non-elevator users is lost
Solution Approach 1:
The system uses cameras to detect user movement behavior as a universal method that works for both elevator users and non-elevator users. The camera-based behavior detection serves multiple functions: tracking elevator users for accurate destination prediction and monitoring non-elevator users for alternative destination inference, thereby achieving universal guidance capability across different user types.
Solution Approach 2:
The system introduces camera-based behavior detection as an intermediary mechanism to bridge the gap between elevator operation data and user destination information. This intermediary captures user movement patterns visually, enabling the system to infer destinations for users who don't operate elevator equipment, thus extending guidance coverage while maintaining accuracy.
2Device complexity
If the system monitors only elevator operations, then data acquisition is simple, but information on non-elevator users is completely lost
Solution Approach 1:
The system replaces the mechanical/electrical elevator operation detection mechanism with an optical camera-based behavior detection system. This substitution enables the capture of user movement information for all users regardless of whether they operate elevator equipment, preventing information loss while the centralized processing keeps overall system complexity manageable.
3Measurement precision
If the system presents destinations based on accumulated use history, then guidance precision for regular users is high, but flexibility for users with diverse interests is reduced
Solution Approach 1:
The system dynamically adjusts destination presentation by integrating real-time camera-based behavior detection with historical usage data. For users with established patterns, it maintains high prediction precision using accumulated history. For users with diverse or changing interests, it dynamically incorporates real-time observed behavior to adapt destination recommendations, thereby achieving both precision and flexibility.

AI summary
There is provided a guidance system capable of guiding a user who does not operate an ascending/descending facility in a building as well on the basis of concern and interest of the user. In a guidance system (1), a behavior information acquisition unit (15) acquires behavior information on an arrival floor of a user. An interest information acquisition unit (20) acquires interest information representing a degree of interest of the user for each attribute on the basis of a relationship between layout and attributes of areas on the arrival floor and the behavior information. A destination presentation unit (22) preferentially presents an area with an attribute with a higher degree of interest as a destination when a user specification unit (14) specifies a user, on the basis of the interest information for the user and information on attributes for each area.
