3D Pointing Device and GUI for Media Navigation
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current media selection interfaces for television and other devices are cumbersome and complex, making it difficult for users to quickly and easily navigate through large collections of media items, despite advancements in technology providing more content options.
Innovation Solution
A 3D pointing device with a minimal set of buttons and a scroll wheel is used in conjunction with a graphical user interface that provides on-screen feedback and zooming capabilities, allowing users to smoothly navigate and select media items by grouping similar selections together and revealing more details as they zoom in.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If the number of buttons and functionality on remote control devices is increased to support additional features and content handling, then the device functionality is improved, but the device complexity and ease of operation deteriorate
Solution Approach 1:
The patent extracts the navigation functionality from the physical remote control and relocates it to the television screen interface. The directional arrows and selection controls are displayed visually on the TV screen rather than requiring multiple physical buttons on the remote, thereby reducing remote complexity while maintaining full navigation functionality.
Solution Approach 2:
The remote control device is designed with universal functionality where a minimal set of buttons can control multiple different functions and interfaces. The same buttons are used for navigating menus, selecting channels, controlling playback, and accessing various applications, eliminating the need for dedicated buttons for each function.
2Quantity of substance
If the number of rows and columns in printed guides is increased to accommodate more channels, then the quantity of information is improved, but the ease of operation and selection speed deteriorate
Solution Approach 1:
The patent transitions from a two-dimensional printed guide layout to a dynamic, multi-level hierarchical interface displayed on the television screen. Information is organized in collapsible categories and subcategories that can be expanded or collapsed, allowing users to navigate through large amounts of information without being overwhelmed by a sprawling flat layout.
Solution Approach 2:
The interface is designed to be dynamic rather than static, allowing the display to adapt to user actions. Menus can be expanded and collapsed, information can be scrolled through, and the interface responds to user input in real-time, making navigation through large amounts of information faster and more intuitive compared to static printed guides.
3Adaptability or versatility
If conventional remote controls with multiple buttons are used to navigate through media selections, then the selection capability is improved, but the time required for viewing and selection increases
Solution Approach 1:
The patent replaces the mechanical button-pressing system with a visual interface system where selections are made by pointing and confirming on the screen. The television display shows the current selection clearly, and users can quickly navigate using directional controls without needing to hunt for specific buttons or remember button functions, significantly reducing selection time.
4Adaptability or versatility
If the framework extends existing selection procedures to accommodate more content, then the adaptability is improved, but the complexity of actions required increases
Solution Approach 1:
The interface is segmented into hierarchical levels and categories that can be independently navigated. Content is divided into logical groups (e.g., channels, programs, on-demand content, recorded content) that can be accessed separately, allowing the system to accommodate large amounts of content without presenting all options simultaneously, thereby maintaining interface simplicity.

AI summary
Systems and methods according to the present invention provide a control framework for organizing, selecting and launching media items including graphical user interfaces coupled with an optional 3D control device for collection of the basic control primitives of point, click, scroll, hover and zoom which permit for easy and rapid selection of media items, e.g., movies, songs etc., from large or small collections. The remote control maps natural hand movements and gestures into relevant commands while the graphical display uses images, zooming for increased/decreased levels of detail and continuity of GUI objects to provide easy organization, selection and navigation among the media items by a user.
