Touchscreen Instant Messaging Interface Gesture Scrolling
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Portable electronic devices face challenges in designing user interfaces that are intuitive and flexible for multifunctional use, particularly for instant messaging, due to small screens and the need for complex key sequences and menu hierarchies, leading to cumbersome interaction.
Innovation Solution
A portable electronic device with a touch-sensitive display and a graphical user interface that allows users to interact through finger contacts and gestures, featuring a method to display messages chronologically and scroll through them vertically, independent of horizontal position, providing an intuitive and adaptive interface for creating, viewing, and managing instant messages.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If physical pushbuttons are used for user interaction, then device functionality can be accessed, but the interface becomes inflexible and requires memorization of complex key sequences and menu hierarchies
Solution Approach 1:
The patent implements a dynamic user interface where the keyboard layout and message list can be repositioned and resized based on user interaction. The interface adapts to different user preferences and contexts, allowing flexible configuration of UI elements rather than fixed physical button arrangements.
Solution Approach 2:
The touch-sensitive display serves multiple functions: it displays messages, provides a virtual keyboard for input, allows scrolling through message history, and enables interface customization. This single multi-functional interface replaces multiple specialized physical buttons while maintaining all necessary capabilities.
2Adaptability or versatility
If the number of functions in a portable device is increased, then device capability improves, but the user interface becomes more complicated and harder to navigate
Solution Approach 1:
The patent combines multiple interface functions into a unified touch-sensitive display system. The keyboard, message list, scrolling controls, and message composition areas are merged into a single flexible interface that can be configured according to user needs, reducing the perceived complexity despite multiple functions.
Solution Approach 2:
The interface is segmented into distinct functional areas (message list region, keyboard region, message composition region) that can be independently positioned and sized. This segmentation allows users to organize the interface according to their specific needs while maintaining access to all functions.
3Adaptability or versatility
If a touch-sensitive display with virtual keyboard is used, then interface flexibility improves, but the area required for message composition and navigation increases
Solution Approach 1:
The keyboard and message list are implemented as dynamic, resizable elements that can be repositioned across the display. Users can adjust the size and position of these elements to optimize the use of available screen space according to their preferences and the current task.
Solution Approach 2:
The interface utilizes the full two-dimensional space of the touch display, allowing elements to be positioned and resized in both horizontal and vertical dimensions. This efficient use of 2D space maximizes the information displayed while maintaining accessibility.
4Reliability
If conventional IM interfaces require repeated keypad pressing to choose characters, then device compatibility is maintained, but message creation becomes cumbersome and time-consuming
Solution Approach 1:
The patent implements a virtual keyboard that displays all available characters and words directly on the touch screen. Users can tap to select characters directly from the visual representation rather than pressing physical keys that require interpretation, significantly speeding up message composition while maintaining compatibility with standard text input protocols.

AI summary
A portable electronic device for instant messaging is disclosed. One aspect of the invention involves a graphical user interface (GUI) on a portable electronic device with a touch screen display. The GUI has a set of messages exchanged between a user of the device and another person. The set of messages are displayed in a chronological order. In response to detecting a scrolling gesture comprising a substantially vertical movement of a user contact with the touch screen display, the display of messages are scrolled in accordance with a direction of the scrolling gesture. The detecting of the scrolling gesture is substantially independent of a horizontal position of the user contact with the touch screen display.
