Dynamic Display Orientation for Multi-User Readability
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Users sitting on opposite sides of a horizontally-oriented display may view content upside down, making it difficult to select buttons or read text, as current technologies lack adequate solutions to this computer-related issue.
Innovation Solution
A device with a processor and touch-sensitive display that uses sensors, such as proximity sensors or cameras, to detect a user's limb and adjust the orientation of input elements, like buttons, to ensure they are presented in a readable orientation based on the user's position, allowing for rotation or reorientation to face the user.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If the display is used in a fixed orientation, then the device structure is simple, but users sitting on opposite sides cannot view content in a readable orientation
Solution Approach 1:
The display orientation is changed from static to dynamic by using sensors to detect user position and automatically rotating the display content to face the user. The system transitions between different orientation states based on real-time user detection, making the display adaptable to different seating positions without requiring multiple physical displays.
Solution Approach 2:
The patent replaces complex mechanical display rotation mechanisms with a software-based orientation adjustment system. Instead of physically rotating the display hardware, the system uses image processing and coordinate transformation to rotate the visual content while keeping the physical display fixed, significantly reducing device complexity.
2Ease of operation
If the display content is rotated to face different users, then user readability is improved, but the system complexity increases due to sensor integration and orientation detection
Solution Approach 1:
The display system automatically detects user position and adjusts orientation without requiring manual intervention. The sensor system and software work together to self-correct the display orientation based on detected user position, eliminating the need for users to manually rotate or reconfigure the display for different seating positions.
Solution Approach 2:
The display system is designed to serve multiple users in different positions simultaneously. By integrating sensor detection with automatic orientation adjustment, the single display can adapt to face different users based on their seating position, making the system universally usable for multiple people around a table without requiring separate displays for each user.
3Ease of operation
If the display automatically adjusts orientation based on user position, then usability for multiple users is improved, but the response time and potential for incorrect orientation changes increase
Solution Approach 1:
The system establishes predetermined orientation states corresponding to different user positions (e.g., north, south, east, west sides of the table). When a user is detected in a general direction, the system selects from these pre-defined orientations rather than calculating arbitrary angles, reducing the risk of incorrect orientation and improving response reliability.
Solution Approach 2:
The system continuously monitors user position through sensors and provides feedback by adjusting display orientation in real-time. This closed-loop control allows the system to verify that orientation changes are producing the desired effect (content facing the user) and make incremental adjustments if needed, improving overall detection accuracy and user experience.

AI summary
In one aspect, a device includes at least one processor, at least one touch-sensitive display accessible to the at least one processor, and storage accessible to the at least one processor. The storage includes instructions executable by the at least one processor to present at least a first input element in a first orientation on the at least one touch-sensitive display and to receive a signal from at least one sensor indicating a direction to a user in proximity to the at least one touch-sensitive display. The instructions are also executable to, responsive to the signal, present the first input element in a second orientation on the at least one touch-sensitive display.
