Touchscreen Gesture Recognition for Flexible User Interface
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional portable electronic devices have inflexible user interfaces that require specific interactions to perform desired functions, leading to user frustration due to the need to memorize these interactions and the difficulty in activating desired buttons.
Innovation Solution
A portable electronic device with a touch-sensitive display and a graphical user interface that allows users to perform similar operations through different finger gestures, enabling a more flexible and intuitive user experience.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If a conventional user interface with physical pushbuttons is used, then the device structure is simple and reliable, but the user interface becomes inflexible and difficult to operate
Solution Approach 1:
The patent replaces physical pushbuttons with a touch-sensitive display that detects finger contacts and gestures. This substitution eliminates mechanical components while enabling multiple interaction modes (tap, swipe, pinch, rotate) through software-based gesture recognition, thereby improving ease of operation without proportionally increasing device complexity
Solution Approach 2:
The touch-sensitive display serves multiple functions: it acts as both the visual display and the input interface. The same surface can detect various gesture types (single-finger taps, multi-finger pinches, rotational movements) to perform different operations, making the interface universally applicable for diverse user interactions without requiring separate physical controls
2Adaptability or versatility
If multiple gesture types are supported for the same function, then user preference and convenience are improved, but the system complexity increases
Solution Approach 1:
The gesture recognition system dynamically adapts to different user preferences and contexts. The same function can be triggered by multiple gesture types (e.g., closing a window via swipe-down, tap-and-hold, or keyboard shortcut), and the system dynamically determines which gesture was intended based on touch patterns, timing, and context, providing adaptability without requiring rigid predefined interaction sequences
Solution Approach 2:
The patent introduces a gesture recognition layer as an intermediary between the physical touch input and the application functions. This mediator translates various physical gestures (finger taps, swipes, pinches) into standardized logical commands that applications can understand, thereby supporting gesture versatility while managing system complexity through abstraction
3Weight of moving object
If the screen size is reduced for portability, then device portability is improved, but the user interface becomes harder to interact with
Solution Approach 1:
The patent utilizes multi-dimensional gesture space to compensate for reduced screen real estate. Instead of relying solely on physical button presses, the system incorporates dimensional gestures (swipe direction, pinch magnitude, rotation angle, press duration) that provide rich interaction control within the limited two-dimensional touchscreen area, maintaining ease of operation despite smaller form factor

AI summary
A portable electronic device with a touch-sensitive display is disclosed. One aspect of the invention involves a computer-implemented method in which the portable electronic device: displays an application on the touch-sensitive display; and when the application is in a predefined mode, performs a predefined operation in response to each gesture of a set of multiple distinct gestures on the touch-sensitive display. Another aspect of the invention involves a computer-implemented method in which the portable electronic device: displays a first application; when the first application is in a first mode, performs a first operation upon detecting a first gesture on the touch-sensitive display; and performs the first operation upon detecting a second gesture on the touch-sensitive display, wherein the second gesture is different from the first gesture.
