Quadrilateral Control Surface for Precise Media Item Selection
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional content sharing platforms face difficulties in allowing users to accurately select items on an axis, particularly when dealing with large volumes of content, as existing media scrub tools often lack precision and user control over scrubbing rates, leading to an inconvenient user experience.
Innovation Solution
Implementing a quadrilateral control surface with multiple scrub areas, each associated with different scrub rates, allowing users to navigate media items at varying speeds without maintaining constant contact with the screen, enabling separate interactions for different scrub rates.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Measurement precision
If a conventional touch and grab control is used to scroll through items on an axis, then users can navigate through content, but the scrolling speed is not controllable and precision is poor
Solution Approach 1:
The patent implements multiple scrub areas with different scrub rates (first scrub rate for coarse navigation, second scrub rate for fine navigation) that dynamically change based on user interaction position and behavior. This allows the system to adapt between fast scrolling and precise positioning, resolving the contradiction between navigation efficiency and selection precision.
Solution Approach 2:
The system changes the scrub rate parameter based on the user's interaction with different regions of the control surface. By modifying the scrub rate from a fixed value to a variable parameter that depends on interaction context, the system achieves both fast navigation and precise selection capabilities.
2Productivity
If a single scrub rate is used for navigating through hundreds or thousands of media items, then the control is simple, but the user cannot efficiently locate specific items
Solution Approach 1:
The control surface is segmented into multiple scrub areas, each associated with different scrub rates. This segmentation allows users to perform coarse navigation quickly using one scrub rate and then switch to a different scrub rate for fine-tuned positioning, significantly improving navigation efficiency through hierarchical control.
Solution Approach 2:
The scrub control surface is designed to perform multiple functions: fast scrolling for initial navigation, medium-speed scrolling for approaching target regions, and slow-speed scrolling for precise item selection. This multi-functionality is achieved within a single unified control interface, maintaining simplicity while enhancing capability.
3Measurement precision
If conventional scrub bars jump in fixed increments, then the control mechanism is simple, but users cannot scrub to exact positions
Solution Approach 1:
The scrub rate is made dynamic rather than fixed, allowing it to change based on user interaction. The system provides adaptability by adjusting scrub rates according to the region of interaction and user behavior patterns, enabling both coarse and fine navigation within the same control mechanism.
Solution Approach 2:
The patent changes the scrub rate parameter from a fixed increment value to a variable parameter that adapts to user needs. By implementing multiple scrub rate parameters that can be selected or transitioned between, the system achieves both positioning accuracy and scrub rate control versatility.
Data Source
AI summary
A method for presenting a media item of a set of media items in a graphical user interface (GUI) of a client device is disclosed. The GUI is provided to present a media item in a set of media items. An input is received to select a first position on the GUI. A continuous movement of the input along a first axis of the GUI is detected to select a second position on the GUI from the first position. Responsive to detecting the continuous movement, a scrub rate corresponding to the second position in association with the first axis of the GUI is determined. A change in a direction of the continuous movement of the input towards a second axis of the GUI is detected. The second axis and the first axis are perpendicular to each other. Responsive to detecting the change in the direction of the continuous movement, one or more media items of the set of media items are advanced according to the scrub rate.
