Multi-Display Focus Indicator Switching by User Presence
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Users of electronic devices with multiple display devices often lose track of the focus indicator when moving between displays due to manual switching or display configurations that hinder the indicator's movement, leading to navigation barriers.
Innovation Solution
The electronic device detects user presence and intent through sensors and determines which display device to display the focus indicator based on proximity, gaze, or profile, adjusting the indicator to match user intent and enhancing usability across multiple displays.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If manual switching between display devices is used, then the focus indicator can be moved between displays, but the user loses track of which display device displays the focus indicator when moving between displays
Solution Approach 1:
The patent applies visual indicators that change appearance or are highlighted to show which display device currently has the focus indicator. This visual feedback mechanism helps users track the focus indicator location across multiple displays without losing spatial awareness.
Solution Approach 2:
The patent introduces an intermediary visual indicator system that mediates between the focus indicator and the user. This intermediary provides additional spatial context information to help users understand which display device is active, bridging the gap between manual switching and user awareness.
2Stability of the object's composition
If display configuration blocks focus indicator movement, then the display order is maintained, but navigation barriers are created
Solution Approach 1:
The patent makes the display configuration dynamic by allowing the focus indicator to move freely between displays based on user input device location, rather than being constrained by a fixed display order. This dynamic approach maintains display configuration stability while enabling smooth navigation.
Solution Approach 2:
The patent segments the navigation control from the display configuration, allowing independent control of focus indicator movement. This separation enables the focus indicator to navigate across displays without being blocked by display configuration constraints.
3Ease of operation
If the focus indicator does not automatically adjust to user location, then manual control is maintained, but user experience and efficiency are reduced
Solution Approach 1:
The patent implements a hybrid approach where the system automatically adjusts the focus indicator based on detected user presence and intent, while still allowing manual control. This self-service capability enhances navigation efficiency without completely removing user control.
Solution Approach 2:
The patent uses sensor feedback (proximity sensors, gaze detection, profile information) to automatically adjust the focus indicator location. This feedback mechanism improves navigation efficiency by anticipating user intent while maintaining the ability for manual override.

AI summary
In some examples, an electronic device includes a first display device including a first sensor and a second display device including a second sensor and a controller to, in response to a detection of a user presence via the first sensor, cause the first display device to display a focus indicator, and in response to a detection of the user presence via the second sensor, cause the second display device to display the focus indicator.
