Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing user interfaces for electronic devices lack robust interaction methods that enhance user experience and reduce interaction time, particularly in battery-operated devices.
Innovation Solution
The implementation of devices with touch-sensitive surfaces that provide functionality information, display a content navigation bar, allow predefined movement, detect user grip, and support character recognition, enabling intuitive user interactions.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Loss of time
If functionality information is not displayed on the input device, then the device structure remains simple, but user interaction time increases and user experience deteriorates
Solution Approach 1:
The patent introduces a display element as an intermediary component between the input mechanism and the user. This display element presents functionality information (such as icons, labels, or visual cues) directly on or near the input device, allowing users to understand available functions without increasing core structural complexity. The display acts as a mediator that bridges the gap between simple input hardware and informed user interaction.
Solution Approach 2:
The input device is segmented into functional components: the input mechanism itself and the display element. This segmentation allows the display functionality to be added as a separate, potentially removable or reconfigurable component, rather than integrating it deeply into the core input structure. This reduces the perceived complexity while enabling enhanced user guidance.
2Loss of information
If detailed functionality information is provided, then user confusion decreases, but information processing requirements increase
Solution Approach 1:
Rather than displaying all possible functionality information continuously, the system applies partial action by showing only relevant functionality cues based on the current input state or user context. This reduces unnecessary information processing and energy consumption while still providing sufficient clarity to prevent user confusion. The display updates selectively rather than continuously.
Solution Approach 2:
The display parameters (such as brightness, update frequency, or information density) are dynamically adjusted based on usage context. For example, the display may show more detailed information when the device is first activated or when uncertainty is detected, and reduce information display during routine operations to conserve energy. This parameter adaptation balances information clarity with energy efficiency.

AI summary
In some embodiments, a device displays functionality information in response to receiving an indication of a first input for which a contact meets functionality display criteria. In some embodiments, a device generates a user interface that includes a navigation bar including images from different positions in a respective content item, and a representation of an adjacent content item. In some embodiments, a device moves a selection-indicator in a user interface by a predefined amount in response to receiving an indication of a first input that meets unitary movement criteria. In some embodiments, a device interprets movement of a contact of an input based at least in part on a grip of a user. In some embodiments, a device displays a plurality of character selection options when a text entry field is not tolerant of character ambiguity and a first input corresponds to a plurality of candidate characters.
