Audio Playback UI Preview via Capacitive Hover Detection
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
User interfaces for controlling audio playback devices lack a preview feature that allows users to efficiently browse and select audio content, leading to an inefficient user experience.
Innovation Solution
A user interface with an input region and display that enables users to preview information associated with entities, such as Internet radio stations and user-defined playlists, before selection, using a finger position sensor to differentiate between previewing and selecting content, allowing for intuitive control of audio playback devices.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If a user interface allows direct selection of entities without preview, then the operation speed is improved, but the user experience quality deteriorates due to inability to make informed selections
Solution Approach 1:
The patent implements a preview function that allows users to listen to audio content before making a selection. The system pre-loads and plays a preview of the audio entity when the user hovers over or approaches the entity in the list, enabling informed decision-making without delaying the subsequent full playback selection process
2Loss of information
If a preview feature is added to the user interface, then the user experience quality is improved, but the device complexity increases due to additional sensors and processing requirements
Solution Approach 1:
The patent makes the input region multi-functional by enabling it to detect both hover gestures (for preview) and selection gestures (for full playback) using the same capacitive touch sensor. The system distinguishes between preview and selection based on the duration and pattern of the touch input, eliminating the need for separate hardware components for each function
3Ease of operation
If the input region differentiates between preview and selection gestures, then the ease of operation is improved, but the measurement precision requirements increase
Solution Approach 1:
The patent differentiates between preview and selection gestures by analyzing temporal parameters of the touch input. A preview gesture is detected when the user hovers or briefly touches the input region, while a selection gesture is detected when the user holds or repeatedly touches the region. The system uses touch duration and repetition patterns as distinguishing parameters to trigger different actions
Applied Scientific Principles
This section explains which scientific principles are used to turn an abstract innovation direction into a practical engineering solution.
Function Achieved in This Case
Enhances user experience by providing a more efficient and enjoyable method for selecting audio content, allowing users to make informed choices through previewing options before playback.
Implementation Method 1
The input region includes a capacitive sensor for detecting a position of a user's finger on the input region
Data Source
AI summary
A user interface (e.g., on remote control device) for controlling an audio playback device. The user interface includes an input region operable to select from a plurality of entities for providing audio content to the audio playback device, and a display for displaying information associated with the entities. The user interface is configured to allow a user to preview the information associated with the entities via the display prior to selection of one of the entities for providing audio content for playback on the audio playback device.
