Floating Icon Rotation Lock for Mobile Display Control
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing methods for controlling the display direction of content on mobile devices are cumbersome and inefficient, requiring users to navigate through settings menus or wait for default content rotations, leading to time-consuming processes.
Innovation Solution
A system that allows users to lock or unlock the display direction by initiating contact with the screen or physical key, using a timer for locking, and automatically refraining from changing the display direction when in a locked state, thereby enabling flexible and efficient control of content orientation.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If users navigate to settings screen and select lock/unlock options, then rotation locking function is achieved, but operation complexity and time consumption increase
Solution Approach 1:
The patent extracts the rotation lock control function from the complex settings menu and places it directly on the display screen as a dedicated icon. This allows users to access and control rotation locking without navigating through multiple menu levels, significantly reducing operational complexity while maintaining the reliability of the locking function.
Solution Approach 2:
The patent introduces a floating icon as an intermediary element between the user and the rotation lock function. This icon serves as a direct interface that users can interact with to lock or unlock rotation, eliminating the need to navigate through settings menus while ensuring the function is reliably activated.
2Adaptability or versatility
If default content rotation occurs after device rotation, then content orientation adapts to device position, but user control and time efficiency are reduced
Solution Approach 1:
The patent enables users to pre-lock the rotation state before device rotation occurs. By allowing users to set the rotation lock in advance through the floating icon, the system prevents automatic content rotation that would otherwise require user intervention to correct, thereby saving time while maintaining adaptability when needed.
Solution Approach 2:
The patent implements visual feedback through the floating icon that indicates whether rotation is locked or unlocked. This immediate feedback allows users to understand the current state without navigating through settings, enabling quick decision-making about whether to lock rotation before device movement, thus reducing time loss while maintaining adaptability.
3Reliability
If floating lock icon is presented only after device rotation, then rotation locking is enabled, but user control is delayed until after default rotation occurs
Solution Approach 1:
The patent makes the floating lock icon available from the beginning, allowing users to lock rotation before device rotation occurs. This preliminary availability of the control interface enables users to prevent unwanted rotation in advance, rather than having to react after default rotation has already happened.
4Reliability
If multiple navigation operations are required to lock rotation, then rotation locking function is achieved, but operational efficiency decreases
Solution Approach 1:
The patent extracts the rotation lock control from the multi-step settings navigation process and provides it through a single-icon interface on the display. This direct access method maintains the reliability of the locking function while dramatically improving operational efficiency by reducing the number of steps from multiple navigation operations to a single tap.
Data Source
AI summary
One embodiment provides a system that facilitates control of the display direction of content on a device. During operation, the system receives, by a client computing device, a first command to lock a state of a display for the device. The system sets a current display state to a locked state. In response to receiving a second command to terminate the first command, the system sets the current display state to a state that is the display state prior to receiving the first command. The system detects a change in a position of the device. In response to determining that the current display state is an unlocked state, the system changes a display direction for content displayed on the device. In response to determining that the current display state is the locked state, the system refrains from changing the display direction for content displayed on the device.
