Projection Mapping Handover Controller for Seamless Content Transfer
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing projection mapping systems face interruptions when users move across different projection areas, as content is not seamlessly handed over between units, disrupting continuous interaction.
Innovation Solution
A system comprising multiple projection mapping units with overlapping areas and a controller that steers projected content and establishes wireless connections to user equipment, ensuring uninterrupted use by handing over content between units or to user devices as needed.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Area of stationary object
If a single projection mapping unit is used, then the device complexity is low, but the coverage area and continuous interaction are limited when users move across areas
Solution Approach 1:
The system divides the coverage area into multiple projection mapping areas, each handled by a separate projection mapping unit. The controller segments the content delivery task by determining which unit should project content based on the projection surface's location, enabling extended coverage while maintaining manageable unit-level complexity
Solution Approach 2:
Multiple projection mapping units are combined under a single controller that coordinates their operations. The controller merges their coverage areas to create a unified projection environment, allowing seamless handover of content between units as the projection surface moves across boundaries
2Ease of operation
If multiple projection mapping units are used without handover capability, then the coverage area is extended, but user interaction is interrupted when moving between areas
Solution Approach 1:
The controller continuously receives location information about the projection surface and uses this feedback to determine which projection mapping unit should currently display the content. This real-time feedback mechanism enables seamless handover between units, maintaining continuous interaction without user awareness of the transition
Solution Approach 2:
The system establishes overlapping projection mapping areas between adjacent units in advance. This preliminary arrangement ensures that when the projection surface approaches a boundary, the target unit is already positioned and ready to receive the content, enabling smooth transitions without interruption
3Reliability
If projection mapping areas overlap, then seamless handover between units is enabled, but the system complexity and coordination requirements increase
Solution Approach 1:
The overlapping projection mapping areas create equipotential zones where multiple units can serve the same spatial region. This design ensures that handover between units occurs in a controlled transition zone rather than at a sharp boundary, improving reliability by providing a buffer area for smooth content transfer

AI summary
A system and method for projected content handover. A projection mapping system may include a plurality of projection mapping units and a controller. Each projection mapping unit has a specific projection mapping area and may project a content onto a projection surface in a corresponding projection mapping area. Projection mapping areas of neighboring projection mapping units overlap each other. The controller is coupled to each of the plurality of projection mapping units and configured to handover the projected content from a first projection mapping unit to a second projection mapping unit as the projection surface moves from a projection mapping area of the first projection mapping unit to a projection mapping area of the second projection mapping unit. The controller may handover the projected content to a user equipment if the projected surface moves out of a combined projection mapping area of the plurality of projection mapping units.
