Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current character input methods on intelligent devices, such as keyboards and touch screens, are inefficient due to the need for manual keystrokes or handwriting, which are time-consuming and require concentration, especially when inputting large amounts of text.
Innovation Solution
A character input method utilizing a built-in camera and optical character recognition technology to capture and recognize text images, allowing users to input characters directly into the device without manual typing or handwriting, thereby saving labor and time.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If keyboard input method is used, then specific feedback after each keystroke is obtained, but many keystrokes are needed for one character input and learning key combination rules is required
Solution Approach 1:
The patent replaces the mechanical keyboard input system with an optical recognition system. Instead of using physical keystrokes to input characters, the system captures images of text using a camera and automatically recognizes the characters through optical character recognition technology, thereby eliminating the need for manual typing while maintaining ease of operation.
2Ease of operation
If touch screen handwriting input method is used, then learning key combination rules is not required, but input speed is relatively low and recognition errors on scrawl handwriting reduce input speed
Solution Approach 1:
The patent replaces the manual handwriting input method with an optical recognition system. Instead of requiring users to write characters by hand on the touch screen, the system captures images of printed or handwritten text and automatically converts them into digital characters through optical character recognition, significantly improving input speed while eliminating handwriting recognition errors.
3Measurement precision
If character input is done one by one through keyboard or touch screen, then each character can be input accurately, but it takes time and requires concentration on both input and text content
Solution Approach 1:
The patent performs preliminary action by capturing the entire text content in advance through image capture. Instead of inputting characters one by one, the system captures an image containing multiple characters and processes them all together through optical character recognition, thereby saving time while maintaining accuracy and allowing users to focus on the text content rather than the input process.
4Productivity
If optical character recognition is used to capture text image, then multiple characters can be recognized at once saving labor and time, but recognition accuracy may be affected
Solution Approach 1:
The patent implements feedback mechanisms in the optical character recognition process. The system provides recognition results to users for verification and correction, allowing users to review and adjust recognized characters if needed. This feedback loop ensures high recognition accuracy while maintaining the efficiency benefits of batch processing multiple characters through image capture and optical recognition.

AI summary
The invention discloses an electronic character input method and a system. The method comprises imaging the text message with an optical imaging device, converting the pointed text information in the text image into character text through an optical character recognition module; and inputting the recognized character text into a current text in process. In addition, modification can be made by, inputting the modified character text into the current text in process. A user can utilize a built-in camera to take a text image for characters to be input, obtain a character text corresponding to the text image through recognition and conversion, input the character text into the text which is currently processed by the intelligent device without inputting the characters in the text image one by one on a keyboard or a touch screen, thereby saving labor and time.
