Solution Overview
Problem
Users face difficulties in inputting data on portable communication devices, such as mobile phones and smartphones, due to the need to manually enter information for various services, which can be cumbersome, especially when using a numeric or small alphanumeric keypad.
Innovation Solution
A method and system that utilize a camera on a portable communication device to capture images, process the image data to recognize and extract text, and output the data in a form noticeable to the user, allowing for simplified data input and utilization across multiple services, with optional external processing units and server support for further processing.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If manual data input using numeric or alphanumeric keypad is used, then data can be entered into the portable communication device, but the operation becomes cumbersome and time-consuming
Solution Approach 1:
The patent replaces the mechanical keypad input system with an optical recognition system using a camera to capture images and extract text data. The camera captures an image containing text, the processor recognizes and extracts the text data from the image, eliminating the need for manual keypad entry and significantly reducing data input time while improving ease of operation
Solution Approach 2:
The patent introduces an intermediary processing system consisting of a camera and text recognition processor that acts as a mediator between the user and the portable communication device. Instead of direct manual input, the user captures an image containing the desired text data, and the intermediary system automatically extracts and inputs the text, resolving the contradiction between ease of operation and time consumption
2Ease of operation
If camera and image processing functionality are added to the portable communication device, then data input is simplified, but the device complexity increases
Solution Approach 1:
The patent applies multi-functionality by using the camera not only for text extraction but also for capturing images that can be used across multiple services. The same camera and processing system serves both as an input device for text data and as an imaging device for various applications, reducing overall device complexity while maintaining ease of operation
Solution Approach 2:
The portable communication device performs self-service by automatically capturing images, recognizing text data, extracting relevant information, and inputting it without requiring external辅助设备. The integrated processor automatically handles the entire workflow from image capture to text extraction and service application, simplifying operation while managing device complexity through automation
