Media Playback Probability Control via Visual Feedback
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Users cannot directly influence the probability of media files being selected for playback in shuffle functions, relying on indirect methods such as listening habits, which limits control over playback order.
Innovation Solution
A method and device that display graphic objects representing media files, allowing users to change their size or color via touch gestures to directly adjust the playback probabilities, enabling users to increase or decrease the likelihood of specific files being played.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If a random selection algorithm is used for shuffle function, then all media files have equal probability of being selected, but the user cannot directly influence the playback order
Solution Approach 1:
The patent uses color changes of graphic objects to represent and adjust playback probabilities. Users can directly modify the color of graphic objects corresponding to media files, and the system automatically calculates updated probabilities based on these color changes. This provides intuitive visual feedback and direct user control without complex interface elements.
Solution Approach 2:
The patent introduces a visual dimension (color space) as an alternative to traditional numerical probability adjustment. Instead of requiring users to input numerical values or navigate complex menus, the system maps probability adjustments to color modifications, transforming a one-dimensional numerical control problem into a two-dimensional visual interaction.
2Adaptability or versatility
If user preferences are recorded over time to determine playback probability, then playback order adapts to listening habits, but the user cannot directly influence selection probabilities
Solution Approach 1:
The patent enables users to perform preliminary actions (modifying graphic object features before playback) to set their desired playback probabilities in advance. Rather than passively adapting to historical listening habits, users can proactively configure their preferences by modifying graphic objects, and these settings are then used to determine the playback order.
Solution Approach 2:
The system provides visual feedback by displaying the features of graphic objects that correspond to playback probabilities. Users can see the current state of their media files and directly modify the graphic object features to adjust probabilities, creating a closed-loop control system where users can observe and refine their playback preferences.
3Ease of operation
If graphic object features are modified to represent probability changes, then users can directly influence playback probability, but the interface requires visual manipulation of multiple objects
Solution Approach 1:
The patent makes the graphic object features serve multiple functions: they represent media files, display playback probabilities, and act as interactive controls for probability adjustment. By modifying a single feature (color) of a graphic object, the system simultaneously achieves visual representation and probability control, eliminating the need for separate control elements.

AI summary
The invention relates to a method for controlling the selection of media data for reproduction. Graphical objects (7, 7.1 – 7.17, 11.1 – 11.15) are displayed, each piece of media data being assigned to a respective graphical object (7, 7.1 – 7.17, 11.1 – 11.15). Furthermore, first probabilities (P1), with which the media data is selected for reproduction, are displayed via a feature (S) of the graphical object (7, 7.1 – 7.17, 11.1 – 11.15) in the method. An operating action of a user is detected and used to change the feature (S) of at least one graphical object (7, 7.1 – 7.17, 11.1 – 11.15). Additionally, second probabilities (P2) are assigned to the graphical objects (7, 7.1 – 7.17, 11.1 – 11.15) dependent on the change of the feature (S) of the at least one graphical object (7.15, 11.13). The media data is selected for reproduction dependent on the second probabilities (P2). The invention further relates to a device (1) for controlling the selection of media data for reproduction.
