Device Orientation Sensor Indexing for Single-Handed UI Navigation
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Mobile devices face challenges in displaying multiple information pieces efficiently due to limited screen size, often requiring users to scroll or use both hands, which can be cumbersome, especially for those without finger nimbleness or with occupied hands.
Innovation Solution
A system that uses sensors to detect angular changes in device orientation, incrementing an index to swap information displayed in a common region of the user interface, allowing users to view additional information with single-handed operation by rotating the device, with animated transitions for a seamless experience.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Loss of information
If scrollable panes are used to access additional information, then more information can be displayed, but the operation becomes cumbersome requiring finger nimbleness or a second hand
Solution Approach 1:
The patent replaces the mechanical scrolling operation (requiring finger dexterity and a second hand) with a sensor-based detection system. The sensor module detects angular changes in device orientation, and the control module automatically switches between information items based on these orientation changes, eliminating the need for manual scrolling operations.
Solution Approach 2:
The system performs automatic information switching based on device orientation detection. The sensor module continuously monitors device orientation, and when a predetermined angular change is detected, the control module automatically increments the index and displays the next information item without requiring user intervention, allowing single-handed operation.
2Loss of information
If larger devices are used to display more information, then greater viewable area is achieved, but the device becomes bulkier
Solution Approach 1:
The patent introduces temporal dimension to the information display by sequentially presenting multiple information items in a single display region over time. Instead of displaying all information simultaneously (spatial arrangement), the system cycles through information items based on device orientation, effectively using time as an additional dimension to increase information capacity without expanding physical display area.
Solution Approach 2:
The patent implements dynamic information display where the visible information item changes based on real-time device orientation detection. The system transitions between different information items dynamically as the user rotates the device, allowing a single display region to serve multiple information presentation functions rather than being static.
Data Source
AI summary
A device may be configured to display a first item in a region of a user interface based on a first value of an index that is associated with the first item. Sensor data may be received from a sensor indicating an angular change of orientation of the device. The index may be incremented to a second value based on the sensor data. The second value may be associated with a second item. The second item may then be displayed in the region of the user interface based on the index being incremented to the second value.
