3D Media Object Navigation on Mobile Terminals
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Mobile terminals face challenges in displaying and navigating large numbers of media objects due to their small screen size and lack of pointing devices, leading to user dissatisfaction and inconvenience in finding specific items.
Innovation Solution
A screen display method using a 3D computer graphics user interface that piles up media objects at end positions and arranges them along a course, allowing sequential movement upon input events, with objects becoming clearer as they approach the center, enhancing visual recognizability and ease of navigation.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Volume of moving object
If media objects are displayed in a conventional list format on a small mobile terminal screen, then the device can be kept portable with small size, but the user experience deteriorates due to difficulty in navigating and identifying media objects among large collections
Solution Approach 1:
The patent transitions from a conventional two-dimensional list view to a three-dimensional spatial arrangement where media objects are piled up at end positions and arranged along a course connecting them. This dimensional change allows multiple media objects to be displayed simultaneously in a visually intuitive manner, improving navigation ease without increasing device size.
Solution Approach 2:
The patent implements dynamic movement of media objects along a course in response to user input events. When a user provides input, media objects sequentially move from one end position toward the other, allowing users to navigate through large collections efficiently. This dynamic behavior enhances ease of operation while maintaining the compact device form factor.
2Quantity of substance
If more media objects are stored in the mobile terminal to increase storage capacity, then the device functionality is improved, but the time required to find a specific media object increases significantly
Solution Approach 1:
The patent pre-arranges media objects in a three-dimensional spatial structure with objects piled at end positions and distributed along a course. This preliminary organization allows users to quickly locate and identify media objects based on their visual positions and sequential arrangements, significantly reducing search time compared to conventional list formats.
Solution Approach 2:
The patent applies visual differentiation to media objects arranged along the course, making them more distinguishable. This visual enhancement technique helps users quickly identify and select specific media objects from large collections, reducing the time required to find desired content.
3Device complexity
If a conventional touchscreen interface is used without pointing devices, then the mobile terminal maintains simplicity and portability, but the precision of media object selection deteriorates
Solution Approach 1:
The patent segments the display area into distinct regions with media objects piled at end positions and arranged along a course. This segmentation creates clear visual boundaries and focal points, allowing users to more easily identify and select specific media objects using only touchscreen gestures, thereby improving selection precision without adding device complexity.

AI summary
A screen display method by which to configure a screen in which media objects are moved according to navigational inputs in order to easily browse for a desired media object from among a plurality of media objects. The screen display method in a mobile terminal includes displaying media objects to be piled up at first and second positions and media objects to be arranged along a course that connects the first and second positions; and displaying the piled-up media objects at one of the first and second positions to be sequentially moved along the course toward the other of the first and second positions when an input event occurs.
