Dynamic Granularity Control Engine for Touch Interface Precision
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional control interfaces on touch-screen devices, such as scroll bars and sliders, often restrict users to navigating in predetermined increments, leading to frustration and inefficiency when trying to accurately select specific positions within content, like videos or audio files.
Innovation Solution
A dynamic granularity control engine that allows users to adjust the precision of control interfaces by entering an adjustment mode, enabling finer or coarser increments through a graphical user interface with zoom-in and zoom-out options, allowing users to customize the control interface view for more accurate selection.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Measurement precision
If conventional control interfaces with predetermined increments are used, then device complexity is reduced and ease of operation is maintained, but measurement precision and selection accuracy deteriorate
Solution Approach 1:
The control interface dynamically adjusts its granularity based on user interaction. When the user activates adjustment mode (e.g., by long-pressing or hovering over the control element), the system transitions from a static coarse-grained interface to a dynamic fine-grained interface, allowing precision adjustments without permanently complicating the default simple interface.
Solution Approach 2:
The patent implements nested control interfaces where a fine-grained adjustment interface is embedded within the coarse-grained interface. When adjustment mode is activated, additional control elements (such as smaller increment buttons or precision sliders) are revealed around or within the main control element, allowing users to access higher precision controls without losing access to the original coarse controls.
2Productivity
If predetermined increment controls are used, then ease of operation is maintained, but productivity and user efficiency deteriorate due to repeated operations
Solution Approach 1:
The system dynamically switches between coarse and fine adjustment modes based on user needs. During normal operation, simple predetermined increments are used for quick navigation. When precision is needed, the user activates adjustment mode which enables fine-grained control, allowing them to reach the desired position in fewer steps without permanently complicating the interface.
Solution Approach 2:
The patent allows users to pre-configure their preferred adjustment increments and modes. The system remembers user preferences and automatically applies appropriate granularity levels, so users don't need to repeatedly adjust controls manually. This preliminary setup reduces the number of operations needed during subsequent navigation tasks.
3Adaptability or versatility
If fixed granularity controls are used, then device complexity is minimized, but adaptability to different user needs deteriorates
Solution Approach 1:
The control interface is designed to be dynamic rather than static. It can switch between different granularity levels and adjustment modes based on user activation. This allows the simple interface to adapt to complex needs when required, providing versatility without permanently increasing structural complexity.
Solution Approach 2:
The patent makes the control interface multi-functional by enabling it to serve both as a simple coarse-adjustment control and as a precision adjustment tool. The same basic control element can operate in different modes (coarse mode for quick navigation, fine mode for precision positioning), making it universally applicable to different user needs without requiring separate controls for each function.
Data Source
AI summary
A user may interact with a control interface in the course of interacting with electronic content. The control interface may include any user interface utilized to adjust various aspects of an application, including, but not limited to, scroll bars, sliders, and/or navigation windows. Input at the control interface may be received from the user indicating that the user desires to manipulate the electronic content (e.g., jump to another location in a movie) or, alternatively, that the user wishes to manipulate the control interface. Upon determining that the input is intended to manipulate the control interface, the control interface may be adjusted to display a control interface view that provides finer or coarser granularity, allowing the user to interact with the control interface with more accuracy.
