Dynamic Display Orientation for Wearable Devices
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional wearable electronic devices struggle with effectively orienting display output in various situations, particularly when the device is rotated or needs to be viewed by others, often requiring awkward contortions or intentional gestures.
Innovation Solution
A wearable electronic device with a dynamic display system that adjusts its presentation orientation based on user gaze direction, detected orientation relative to the user's body, and touch input, using a combination of gaze detectors, orientation detectors, and control circuits to prioritize and alter display content accordingly.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If display output is aligned with geometric configuration of the device, then display orientation is simple and stable, but display output cannot be appropriately oriented in all situations
Solution Approach 1:
The display orientation is made dynamic rather than fixed. The system continuously monitors user interactions (touch gestures, device movement) and automatically adjusts display orientation in real-time. This allows the display to adapt to different viewing situations without requiring complex manual controls or multiple physical display configurations.
Solution Approach 2:
The display system serves itself by automatically detecting user intent through touch gestures and device orientation sensors, then autonomously adjusting the display orientation. This eliminates the need for users to manually configure display settings or perform awkward physical contortions to view content appropriately.
2Ease of operation
If gravity detector is used to rotate display output, then display automatically adjusts to device rotation, but display output alignment is insufficient in all situations
Solution Approach 1:
The system uses multiple sensing mechanisms beyond just gravity detection, including touch gesture recognition and device movement sensors. These multiple functions work together to cover a broader range of viewing situations, whether the user is holding the device, wearing it, or sharing it with others, making the display orientation system universally applicable to all usage scenarios.
Solution Approach 2:
The system continuously receives feedback from touch gestures and motion sensors to dynamically adjust display orientation. When the user performs a specific gesture or the device is moved to a different orientation, the system detects this feedback and automatically reorients the display accordingly, ensuring continuous adaptability to user needs.
3Loss of information
If display is continuously active to provide information, then information availability is high, but energy consumption increases
Solution Approach 1:
Instead of keeping the entire display continuously active, the system uses periodic updates triggered by user interactions. The display remains in lower-power states between interactions and only activates or updates content when the user performs a gesture or the system detects a change in usage context, reducing overall energy consumption while maintaining information accessibility when needed.
Solution Approach 2:
The system applies different activation states to different portions of the display based on user interaction patterns. When the user engages with specific areas of the display through touch gestures, only those relevant portions remain active while other areas can enter lower-power states, optimizing the balance between information availability and energy consumption.
Data Source
AI summary
An electronic device can include detectors for altering the presentation of data on one or more displays. In a wearable electronic device, a flexible housing can be configured to enfold about an appendage of a user, such as a user's wrist. A display can disposed along a major face of the flexible housing. A control circuit can be operable with the display. A gaze detector can be included to detect a gaze direction, and optionally a gaze cone. An orientation detector can be configured to detect an orientation of the electronic device relative to the user. The control circuit can alter a presentation of data on the display in response to a detected gaze direction, in response to detected orientation of the wearable electronic device relative to the user, in response to touch or gesture input, or combinations thereof. Secondary displays can be hingedly coupled to the electronic device.
