Touch Screen Interface for 3D Virtual Object Manipulation
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional user interfaces for portable electronic devices with touch screen displays are complex and inflexible, making it difficult for users to interact with three-dimensional virtual objects, especially on devices with small screens, leading to frustration due to the need for memorizing key sequences and menu hierarchies.
Innovation Solution
A portable electronic device with a touch-sensitive display that uses finger gestures to navigate and manipulate three-dimensional virtual objects, featuring animated transitions and rotations within a three-dimensional virtual space, allowing users to interact intuitively through gestures such as taps, swipes, and multi-finger movements.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If conventional user interfaces with physical pushbuttons are used, then users can access device functions, but the interface becomes complex and inflexible requiring memorization of key sequences and menu hierarchies
Solution Approach 1:
The patent replaces physical pushbutton mechanisms with a touch-sensitive display interface that uses gestures (taps, swipes, pinches) to control device functions. This substitution eliminates the need for memorizing key sequences and menu hierarchies while reducing interface complexity through direct visual interaction with virtual objects in three-dimensional space
Solution Approach 2:
The patent transitions from two-dimensional pushbutton interfaces to three-dimensional virtual objects displayed on the touch screen. Users interact with spatially arranged virtual objects using gestures, adding a dimensional layer that simplifies navigation and reduces the cognitive load associated with conventional menu hierarchies
2Adaptability or versatility
If the number of functions performed by a device increases, then device versatility improves, but the user interface becomes more complex and difficult to operate
Solution Approach 1:
The patent implements a universal touch-sensitive display interface that handles multiple device functions through a single consistent interaction paradigm. Virtual objects represent various functions (phone, camera, music player, etc.) and can be accessed through uniform gesture-based operations, allowing users to operate multifunctional devices without learning function-specific interfaces
Solution Approach 2:
The patent employs dynamic rendering of three-dimensional virtual objects that respond to user gestures in real-time. The interface adapts its behavior based on the virtual object being interacted with, providing context-aware controls while maintaining a consistent overall interface structure that manages device versatility without increasing complexity
3Weight of moving object
If the screen size of portable devices is reduced, then device portability improves, but the user interface becomes harder to navigate and manipulate
Solution Approach 1:
The patent compensates for reduced screen real estate by utilizing three-dimensional spatial arrangement of virtual objects. Objects are distributed in 3D space rather than crowded on a 2D plane, providing adequate interaction space on small portable devices while maintaining ease of navigation through gesture-based manipulation
Solution Approach 2:
The patent employs curved or spherical three-dimensional virtual objects that provide natural grip and interaction surfaces for finger gestures. This curvature enables intuitive manipulation on small screens, allowing users to pinch, rotate, and translate objects comfortably despite the limited display area
