Interactive Projection Touch Mapping for Cross-Device Absolute Control
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing interactive projection systems lack the ability to transmit absolute coordinates, requiring dedicated software or APP installation on external devices for control, and cannot achieve coordinated control across systems and devices.
Innovation Solution
An interactive projection input and output device that includes a projecting module, operation capturing module, instruction generating module, and wireless transmission module, which correlate the projection region with the operation scope, capture user operations, generate position information instructions, and transmit them wirelessly to external devices without the need for additional software or APP installation, using a hardware computing circuit to adapt to different operating systems.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If a projector is mounted on the ceiling to save floor space and provide a wide viewing angle, then the viewing experience is improved, but cleaning and maintenance become difficult and time-consuming
Solution Approach 1:
The projector is mounted on a robotic cleaning system that can dynamically move between ceiling-mounted projection positions and accessible cleaning positions. The system transitions from a static ceiling-mounted configuration to a dynamic mobile platform, allowing the projector to be both ceiling-mounted for projection and easily accessible for cleaning through robotic manipulation.
Solution Approach 2:
The robotic cleaning system autonomously cleans the projector without human intervention. The robot navigates to the projector, positions cleaning components, and performs cleaning tasks automatically, enabling the projector to be self-maintained while remaining ceiling-mounted for optimal viewing angles.
2Ease of repair
If the projector is placed on the floor for easy access, then cleaning and maintenance are convenient, but floor space is occupied and the viewing angle is limited
Solution Approach 1:
The system uses a mobile robotic platform that can dynamically position itself for cleaning operations rather than requiring the projector to remain statically on the floor. This allows the projector to be mounted in optimal positions while the robot provides accessible cleaning capabilities.
Solution Approach 2:
The robotic cleaning system acts as an intermediary between the ceiling-mounted projector and the cleaning process. Instead of directly placing the projector on the floor, the robot serves as a mobile intermediary that brings cleaning capabilities to the projector's location without occupying permanent floor space.
3Manufacturing precision
If the projector is mounted high on the ceiling for optimal viewing angle, then the projection quality is improved, but the projector becomes difficult to reach for cleaning
Solution Approach 1:
The robotic cleaning system provides autonomous self-service cleaning capabilities for ceiling-mounted projectors. The robot navigates to high ceiling locations, positions itself appropriately, and performs cleaning tasks without requiring human workers to physically access difficult-to-reach areas.
Solution Approach 2:
The mobile robotic system serves as an intermediary that bridges the gap between the high ceiling mounting position and the cleaning process. The robot extends human capabilities to reach and clean projectors mounted at optimal high positions that would otherwise be inaccessible.
