AR-Free Schedule Display via Spatial Detection
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing techniques for displaying schedule information of absences in offices require pre-arranged AR markers, which are labor-intensive to set up and function poorly when out of range or obstructed.
Innovation Solution
An information display device that detects its own position and direction, calculates the position of a target seat, and acquires activity schedule information from a database to display on a user-friendly interface without the need for pre-arranged AR markers.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If AR markers are pre-arranged on desks to display schedule information, then schedule information can be presented, but labor for setup increases and the system becomes constrained by marker placement requirements
Solution Approach 1:
The patent replaces physical AR markers with virtual markers generated by the imaging device. Instead of requiring physical copies (markers) to be placed on each desk, the system creates virtual representations of seats and users through image processing and overlay technology, eliminating the need for physical marker installation while maintaining the information display function
Solution Approach 2:
The patent substitutes the mechanical system of physical marker placement and recognition with an optical-digital system. The imaging device captures images, processes them to identify users and seats, and displays information through digital overlays, replacing the need for physical marker arrangement and optical recognition of physical markers
2Reliability
If AR markers are used for presence detection, then activity schedules can be displayed, but the system fails when markers are out of photographing range or obstructed
Solution Approach 1:
The imaging device performs multiple functions: it captures images for both presence detection and schedule information display, generates virtual markers, and processes user identification. This multi-functional approach eliminates the single-point-failure issue where physical markers could be obstructed or out of range, as the system adapts to various viewing conditions and distances
Solution Approach 2:
The system uses the imaging device's own captured images to generate and display information, rather than relying on external physical markers. The device processes its own imaging data to identify users, determine presence, and display relevant information, making the system self-sufficient and adaptable to different environmental conditions
3Ease of operation
If physical AR markers are deployed throughout the office, then schedule information becomes accessible, but the complexity of the system increases
Solution Approach 1:
The patent extracts the information display function from the physical marker infrastructure and consolidates it into the imaging device. Instead of having a distributed system requiring markers on every desk, the system centralizes the intelligence in the imaging device, which processes images and displays information as needed, simplifying the overall system architecture

AI summary
An information display device for displaying activity schedule of an assigned user provided with one of seats in advance, detects position and direction of the information display device; acquires distance from the information display device to a display target seat of an assigned user whose activity schedule is to be displayed; uses the position, the direction, and the distance to calculate display seat position of the display target seat; extracts, from a table which registers assigned user information of assigned users of the seats in association with registration seat position of the seats, one piece of the assigned user information registered in association with one piece of the registration seat position which is closest to the display seat position; acquires current activity schedule registered in association with the one piece of the assigned user information; and displays the acquired activity schedule on a display unit.
