Collaborative Data Editing via Camera-Based Image Capture
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Collaborative participants in virtual collaboration spaces often lack the necessary tools, such as electronic pens and sensors, leading to lower work efficiency as they typically work in turn using a single pen, restricting simultaneous data manipulation.
Innovation Solution
A collaborative system and method that enables participants to use portable processing devices with cameras to transmit images and identification information, allowing for data editing and updates without the need for additional tools, facilitating simultaneous work through a common screen.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If electronic pens and sensors are used for collaborative work, then data manipulation capability is improved, but device complexity and cost increase
Solution Approach 1:
The patent uses the camera to capture images of the screen content, creating a visual copy of the data. Participants can then manipulate this copied information through their portable devices, eliminating the need for physical electronic pens while maintaining full data manipulation capability through digital replication and processing of the visual information.
Solution Approach 2:
The portable processing device with camera serves multiple functions: it captures screen content, processes the visual information, enables data manipulation, and facilitates collaborative interaction. This multi-functional approach replaces the specialized electronic pen and sensor system, reducing device complexity while maintaining operational capability.
2Device complexity
If a single electronic pen is shared among participants, then device complexity is reduced, but productivity decreases due to sequential work
Solution Approach 1:
The system segments the data manipulation function from the display function. The screen serves as the shared display, while each participant's portable device becomes an independent manipulation station. This segmentation allows simultaneous access and editing by multiple users without requiring multiple physical pens, as each user interacts with the system through their own device's interface.
Solution Approach 2:
The patent transitions from a single-dimensional interaction model (one pen, one user at a time) to a multi-dimensional model where multiple users can simultaneously access and manipulate data through their respective portable devices. The camera-based image transmission creates a new dimension of interaction, allowing parallel data manipulation across multiple devices while maintaining a single shared display.
3Productivity
If electronic pens are required for each participant, then simultaneous data manipulation is enabled, but cost and device complexity increase
Solution Approach 1:
Instead of providing each participant with a physical electronic pen, the system creates digital copies of the screen content through camera imaging. Each participant receives and manipulates these image copies through their portable device, enabling simultaneous data manipulation without requiring multiple physical writing instruments.
Solution Approach 2:
The patent replaces the mechanical electronic pen system with a camera-based imaging and digital processing system. The camera captures the screen content, and the portable devices process and manipulate the digital image data, substituting the mechanical writing interaction with optical capture and digital manipulation, thereby eliminating the need for multiple electronic pens.
Data Source
AI summary
A system uses portable processing devices that communicate with external devices. A portable processing device having a camera transmits, to a server, an identification information request message including an image acquired by the camera; receives, from the server, identification information related to an object shown in the image; in response to user selection of the object, transmits, to the server, a data request message requesting data corresponding to the identification information of the selected object; receives, from the server, a first data corresponding to the identification information; edits the first data to provide a second data in response to user input information; and transmits the second data to the server enabling the server to update the first data to provide the second data item.
