Mobile Device Projector Camera System for External Screen Data Capture
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current mobile devices lack the capability to efficiently capture and convert user-drawn or written data from an external screen, such as a whiteboard, into usable digital data.
Innovation Solution
A mobile device equipped with a projector module to output images and a camera module to capture the external screen, with a controller that compares the output and captured images to extract and create data from user inputs, allowing for the conversion of drawings or text into digital format.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If a mobile device outputs images to an external screen for user input, then the ease of operation is improved, but the capability to capture and convert user-drawn data into digital format is insufficient
Solution Approach 1:
The mobile device integrates multiple functions including projector module for output, camera module for capture, and controller for image comparison and data extraction. This multi-functional system allows the device to not only display images on external screens but also capture user inputs and convert them into digital data, resolving the limitation of insufficient data capture capability
2Adaptability or versatility
If the device captures and processes user inputs from external screens, then the adaptability is improved, but the device complexity increases
Solution Approach 1:
The patent merges the projector module, camera module, and controller into an integrated system. The controller combines image capture, comparison, and data extraction functions into a single processing unit, reducing overall system complexity while maintaining enhanced adaptability for capturing user inputs from external screens
3Productivity
If the mobile device stores user-generated data from external screens, then the productivity is improved, but the loss of information is reduced
Solution Approach 1:
The camera module creates a captured image copy of the external screen showing user inputs. This optical copy is then processed by the controller to extract and store digital data, ensuring accurate reproduction and retention of user-generated information without loss
Data Source
AI summary
A method and system for generating data in a mobile device is provided. The method includes, outputting an image, stored in the mobile device, to an external screen, capturing the external screen on which the image is being displayed and creating a captured image, comparing the output image with the captured image and extracting an added image from the captured image, and creating data from the extracted image. When the mobile device user writes or draws on an external screen on which the mobile device outputs an image, the mobile device can capture the external screen, create data from the user's input content and store them in the storage unit.
