Morphing User-Interface Control Object for Media Playback
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing graphical user interfaces (GUIs) for media control lack efficient methods to transition between control objects, such as play/pause and playback rate controls, within a limited space, making it cumbersome for users to access different functionalities without navigating through multiple layers of menus.
Innovation Solution
The system morphs a first control object, such as a play/pause button, into a second control object, like a slider or jog shuttle, in response to specific user inputs, allowing users to control playback rate by interacting with the slider along a slide rail, and automatically returns to the original control object upon input termination.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If multiple control objects are provided in a limited interface space, then control functionality is improved, but interface clutter increases
Solution Approach 1:
The patent combines multiple control objects (play/pause button and playback rate slider) into a single unified control object. The play/pause button and slider share the same spatial location, allowing users to access both functionalities without occupying separate interface space. When the user interacts with the play/pause button, it dynamically transforms into the slider control, enabling playback rate adjustment from the same position.
Solution Approach 2:
The control object is designed to perform multiple functions: it can act as a play/pause toggle button in its default state and transform into a playback rate slider when activated. This multi-functionality allows a single control object to replace what would traditionally require multiple separate controls, thereby improving control functionality while maintaining a compact interface.
2Adaptability or versatility
If control objects are added to provide more functionalities, then adaptability is improved, but device complexity increases
Solution Approach 1:
The control object is designed to be dynamic rather than static. It can change its form and function based on user interaction: starting as a play/pause button and transforming into a slider when the user activates it. This dynamic behavior allows the interface to adapt to user needs without requiring multiple separate static controls, thereby reducing interface structural complexity while maintaining functional versatility.
Solution Approach 2:
The patent implements a nested structure where the slider control is embedded within the play/pause button control. When the user interacts with the play/pause button, the slider control emerges from within it, allowing the user to adjust playback rate. After use, the slider nestles back into the button, returning to its original state. This nesting approach consolidates multiple controls into one, reducing overall interface complexity.
3Area of stationary object
If control objects are removed to reduce clutter, then interface simplicity is improved, but ease of operation deteriorates
Solution Approach 1:
The slider control is pre-positioned within the play/pause button, ready for immediate access. When the user needs to adjust playback rate, the slider is already there, embedded within the button's spatial location. This preliminary positioning ensures that users can access the slider without navigating through multiple layers or searching for separate controls, maintaining ease of operation while keeping the interface clean and uncluttered.

AI summary
Systems and techniques are disclosed for morphing a first control object in a user-interface into a second control object. According to some implementations, the first control object is provided for display on a graphical user interface presented on a display of a device. The first control object can be configured to control a parameter of a presentation of media content in response to a first input. An interaction input is received indicating a user interaction with the first control object. In response to the interaction input, the first control object can be morphed into a second control object, replacing the first control object. A second input can be received, the second input indicating an intention of the user to change a value of the second control object. And, the value of the second control object can be adjusted according to the second input.
