Portable Terminal Character Input via Image Transmission
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing character input methods for information processing apparatuses require users to switch between their portable terminal apparatuses and the information processing apparatus, making it cumbersome to input characters, as they need to use an original character input tool or an IME-based tool, and often lack access to the portable terminal's functions.
Innovation Solution
A system where the information processing apparatus requests and displays an image of a character input tool from a portable terminal apparatus, allowing users to input characters by touching keys on the displayed tool, with the portable terminal identifying and transmitting the characters, and updating the tool's image upon screen changes, enabling seamless character input without needing to constantly switch between devices.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If users use the original character input tool provided by the manufacturer, then the information processing apparatus can perform character input, but users need to make efforts to learn how to use it
Solution Approach 1:
The patent applies the copying principle by displaying a reproduced image of the portable terminal's character input tool on the information processing apparatus's touch panel. Instead of requiring users to learn a completely new original tool, the system copies the familiar interface from the portable terminal and presents it on the larger display, allowing users to input characters using their existing knowledge and habits.
2Productivity
If users use IME-based character input tool on portable terminal, then users can input characters efficiently, but users need to switch between portable terminal and information processing apparatus
Solution Approach 1:
The patent merges the character input functionality from the portable terminal with the information processing apparatus by displaying the portable terminal's character input tool image on the information processing apparatus's display. This allows users to maintain their familiar input workflow on the portable terminal while having the character input areas on the information processing apparatus, eliminating the need to physically switch devices during the input process.
Solution Approach 2:
The patent uses an intermediary approach by capturing images of the portable terminal's character input tool and transmitting them to the information processing apparatus. This intermediary mechanism allows the system to bridge the gap between the portable terminal's familiar interface and the information processing apparatus's display, enabling seamless character input without direct device switching.
3Reliability
If information processing apparatus displays original character input tool, then the apparatus can process character input, but the tool does not reflect changes made on the portable terminal
Solution Approach 1:
The patent implements feedback by continuously capturing images of the portable terminal's character input tool after user interactions and transmitting these updated images to the information processing apparatus. This ensures that any changes, modifications, or selections made on the portable terminal are reflected in real-time on the information processing apparatus's display, maintaining synchronization and accuracy throughout the character input process.
Data Source
AI summary
A portable terminal apparatus includes an access portion that enables access to an information processing apparatus; an image obtaining portion that obtains an image of a character input tool, a transmitter that transmits the image of the character input tool to the information processing apparatus; a receiver that receives touched key information from the information processing apparatus, and a character identification portion that identifies a character on the basis of the touched key information received by the receiver, wherein the image obtaining portion obtains a different image of the character input tool upon each change to a screen appearance of the character input tool or upon each receipt of the touched key information and the transmitter transmits the different image of the character input tool and character information to the information processing apparatus.
