Tabletop Mobile Augmented Reality System for Cooperative Interaction
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing tabletop augmented reality systems face challenges in allowing multiple users to simultaneously interact and control content fairly, as larger screens increase manufacturing costs and physical object-based methods restrict equal access to control rights, and horizontal displays struggle to show content uniformly across directions.
Innovation Solution
A tabletop, mobile augmented reality system with a table interface and mobile interface that uses touch frames, cameras, and network modules to recognize and trace objects, allowing users to manipulate three-dimensional content and share results, while maintaining equal control rights through synchronized coordinate data transmission.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Area of stationary object
If the screen size is increased to provide better visibility and interaction space, then the user experience is improved, but the manufacturing cost increases
Solution Approach 1:
The patent combines the table interface and mobile interface into a unified augmented reality system. The mobile device's display is merged with the table's projected image to create an extended cooperative space, allowing users to access content without requiring a larger physical table screen.
Solution Approach 2:
The system transitions from a two-dimensional table surface to a three-dimensional augmented reality space. By projecting images onto the table and augmenting them with 3D content on mobile devices, the system expands the interaction space vertically and spatially without increasing the table's physical footprint.
2Ease of operation
If physical objects are used for interaction in a multilateral environment, then tactile interaction is improved, but the control right becomes restricted to the number of physical objects available
Solution Approach 1:
The system makes the interaction interface universal by allowing multiple users to access and control the same content simultaneously through their respective mobile devices. The table interface serves as a shared cooperative space that can be accessed by any number of users, eliminating the limitation of physical object quantity.
Solution Approach 2:
The system creates virtual copies of interaction objects in the augmented reality space. Instead of limiting users to physical objects, the system generates digital replicas that can be manipulated through mobile devices, allowing unlimited simultaneous access to control rights.
3Adaptability or versatility
If the table screen is divided into multiple user sections, then each user gets personal space, but the screen size per user decreases as the number of users increases
Solution Approach 1:
The system resolves the screen division problem by moving from a two-dimensional table surface to a three-dimensional augmented reality environment. Each user's mobile device displays their personal space in 3D, allowing multiple users to have full-sized personal interfaces simultaneously without dividing the physical table screen.
Solution Approach 2:
The mobile device acts as an intermediary between the user and the table interface. It translates the shared table content into personalized views for each user, allowing them to access their personal space with full screen real estate without physically dividing the table display.
4Adaptability or versatility
If a circular turnable screen is implemented, then all users can access content, but users must compete for control right to turn the screen
Solution Approach 1:
The system segments the control authority by giving each user independent control over their own mobile device interface. Instead of one shared control mechanism that requires taking turns, each user has their own control channel to access and manipulate content in their personal augmented reality space.
Solution Approach 2:
The mobile device serves as an intermediary that translates shared table content into personalized views. Each user's device independently processes and displays content, eliminating the need for a central control mechanism that would require users to compete for access.
