Audio Menu Navigation for Displayless Single-Button Devices
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Electronic devices without displays face challenges in providing user interfaces for controlling operations due to size constraints, requiring an audio-based interface for simple and complex operations, where insufficient input combinations limit functionality and user information access.
Innovation Solution
An audio user interface is implemented using a single input interface, where different button presses and durations are associated with various playback controls, and an audio menu provides information and options through audio clips, allowing users to select playlist, audiobook, or metadata-based options, with the ability to navigate multi-dimensional menus.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Volume of moving object
If the device includes no display and only a single input interface to reduce size, then device size is reduced, but the functionality and user information access become insufficient
Solution Approach 1:
The patent transitions from visual display to audio output, adding a temporal dimension to the user interface. Audio menus provide sequential information through spoken clips, allowing complex device operations to be controlled through voice and audio feedback rather than visual displays, thus maintaining functionality while reducing device size.
Solution Approach 2:
The patent introduces an audio menu system as an intermediary between the single input interface and device operations. The audio menu acts as a mediator that provides comprehensive information and control options through audio clips, enabling the single button to access multiple functions that would otherwise require multiple buttons or a display.
2Volume of moving object
If the device includes no display and only a single input interface to reduce size, then device size is reduced, but user information access becomes limited
Solution Approach 1:
The patent replaces the mechanical visual display system with an audio output system. Instead of using a display screen to present information, the system uses audio clips and spoken instructions to convey device state, menu options, and operational information, thereby reducing device size while maintaining information accessibility.
Solution Approach 2:
The audio menu system provides self-service information delivery by automatically announcing available options and device state through audio clips. The system guides the user through menu structures and operation selections without requiring visual confirmation, enabling users to access and understand device information through audio feedback alone.
3Device complexity
If different button presses and combinations are used to control operations, then device complexity is reduced, but the number of controllable operations becomes insufficient
Solution Approach 1:
The patent makes the single input interface universal by enabling it to control multiple device operations through the audio menu system. The single button can trigger playback operations, access audio menus, navigate through options, and execute various device functions, making one component perform the work of multiple buttons while maintaining full operational control.
Solution Approach 2:
The patent introduces dynamic behavior to the single input interface by recognizing different press patterns (duration, sequence, combination with other inputs) to trigger different functions. The system dynamically interprets button press characteristics to distinguish between simple playback controls and complex menu navigation, enabling a single static component to provide diverse operational control.

AI summary
This invention is directed to an audio menu provided in an electronic device having no display. The electronic device can further include an input interface having only a single sensing element (e.g., a single button) for controlling audio playback of the device and for accessing and controlling the device audio menu. In response to a particular input detected by the single sensing element, the electronic device can enable an audio menu mode and play back audio clips associated with different menu options. The user can provide selection instructions using the single sensing element during the playback of an audio clip to select the menu option associated with the played back audio clip. In some embodiments, the audio menu can be multi-dimensional (e.g., the device plays back audio clips for sub-options in response to a selection of a menu option). Suitable menu options can include, for example, groupings of audio (e.g., playlists), options to toggle (e.g., a shuffle option), or options associated with particular metadata tags associated with audio available to the device.
