Find Innovative SolutionsGenerate Solutions

Solution Overview

Problem

Conventional chat systems in social networking services rely solely on text input via keyboards, limiting the mode of communication and not allowing for a more expressive form of interaction between users.

Innovation Solution

An image distribution method and server device that enables users to chat by handwriting, where a terminal device receives and displays handwritten images as messages in a virtual space, allowing users to create and share messages through a touch panel, with hash values used for message distribution and retrieval between connected devices.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Adaptability or versatility

If text input via keyboard is used for chatting, then communication can be achieved, but the mode of communication is limited and expressiveness is reduced

Engineering Contradiction:

Improvecommunication modeVSAvoidinput method

Core Design Contradiction:

Adaptability or versatilityVSEase of operation

Solution Approach 1:

The patent changes the input parameter from keyboard text input to handwriting input on a touch panel. This allows users to write characters, draw pictures, and create various visual expressions directly on the screen, significantly expanding communication modes while maintaining ease of operation through natural writing gestures

Inventive Principle:

Principle #35Parameter changes

Solution Approach 2:

The patent replaces the mechanical keyboard system with a touch panel system that detects handwriting trajectories. This substitution enables direct visual expression through handwriting, drawings, and other graphical inputs, transforming the communication interface from text-only to multi-modal visual communication

Inventive Principle:

Principle #28Mechanics substitution (Replace mechanical system)

2Adaptability or versatility

If handwriting input is enabled on touch panel, then communication expressiveness is enhanced, but device complexity increases

Engineering Contradiction:

Improvecommunication modeVSAvoidsystem structure

Core Design Contradiction:

Adaptability or versatilityVSDevice complexity

Solution Approach 1:

The touch panel serves multiple functions: it acts as both the display screen and the input device for handwriting. The same panel that displays the chat interface also captures handwriting trajectories, eliminating the need for separate input hardware and reducing overall system complexity despite enhanced functionality

Inventive Principle:

Principle #6Universality (Multi-functionality)

Solution Approach 2:

The system uses the existing touch panel capabilities to perform both display and input functions. The touch panel's inherent touch detection capability is leveraged to capture handwriting without requiring additional specialized hardware, allowing the system to serve multiple purposes with existing components

Inventive Principle:

Principle #25Self-service

AI summary

An image distribution device receives, from a terminal device, a handwritten and input image including a trajectory handwritten and inputted by a first user in a state where a virtual space, in which characters of the first and a second user are present, is set as a background, to a display view of the terminal device on which the virtual space is displayed. By transmitting, to the terminal device, the received handwritten and input image as a message from the first user, the image distribution device displays the handwritten and input image on the display view of the terminal device on which the virtual space is displayed while associating the handwritten and input image with the character of the first user.
