Single-Hand Operation Cursor for Full-Screen Smart Devices
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Users face difficulties in performing single-hand operations on large-screen smart devices as existing solutions require zooming out the full screen, which is inconvenient and cumbersome.
Innovation Solution
A method and apparatus that activate a single-hand operation mode by displaying a cursor indicator on the screen, allowing it to be moved along a sliding track, and triggering instructions within a specific region without zooming out the full screen, enabling single-hand operation across the entire screen without zooming out the content.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If the full screen is zoomed out to enable single-hand operation, then single-hand operability is improved, but display quality and screen utilization deteriorate
Solution Approach 1:
A cursor indicator is introduced as an intermediary element that mediates between the user's touch input and the target content on the full screen. The cursor acts as a pointer that can be precisely controlled within a small operational area while indicating content across the entire screen, eliminating the need to zoom out the display.
Solution Approach 2:
The solution adds a new dimension to the interaction by introducing a cursor indicator that moves independently from the touch input position. The cursor's position in one dimension (visual indication on full screen) is decoupled from the touch position in another dimension (small operational area), allowing full screen access with limited hand movement.
2Ease of operation
If a cursor indicator system is implemented for single-hand operation, then ease of operation is improved, but device complexity increases
Solution Approach 1:
The cursor indicator serves as a visual copy or representation of the touch input position, but transformed to map to the full screen coordinates. This copying mechanism allows the system to process simple touch inputs while providing comprehensive full screen navigation, managing complexity through virtual representation rather than physical interaction changes.

AI summary
The present disclosure relates to a method and an apparatus for single-hand operation on a full screen of a smart device, which pertains to the field of computer technology. The method for single-hand operation on a full screen includes determining whether a single-hand operation mode is activated, displaying a cursor indicator on the screen of the smart device when the single-hand operation is activated, moving the cursor indicator based on a track generated by a sliding operation on the screen of the smart device, determining whether the cursor indicator is moved into a trigger region, and activating the trigger region to receive an instruction associated with a touch event on the screen when the cursor indicator is moved into the trigger region. The touch event locates outside the trigger region.
