Hover and Touch Display for One-Handed Operation
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current technologies for one-handed operation of smartphones with touch-based UIs are limited, often making content harder to read or restricting usability due to scaling or specific use cases, and are not flexible enough to accommodate different hand positions, leading to user experience issues and increased risk of dropping the device.
Innovation Solution
A hover and touch sensitive display device that detects swipe gestures followed by lifting, allowing continuous cursor control based on object height and movement, enabling one-handed operation without scaling the display content, using sensors like capacitive proximity and radar to manage cursor placement and function activation.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If the display content is scaled down to a sub-area to enable one-handed operation, then the ease of operation is improved, but the readability and user experience deteriorate
Solution Approach 1:
The patent introduces a third dimension (depth/height above screen surface) to the traditional two-dimensional touchscreen interaction. By detecting the height of the object above the screen surface, the system enables cursor control in 3D space, allowing users to operate the interface without scaling the display content, thus maintaining readability while enabling one-handed operation.
Solution Approach 2:
The patent introduces a cursor as an intermediary element between the user's hand and the display content. The cursor acts as a mediator that can be positioned and controlled through hover gestures, allowing users to interact with full-resolution display content without needing to physically reach across the entire screen, thus resolving the contradiction between ease of one-handed operation and content readability.
2Ease of operation
If the complete display content is shifted to retain original size with only parts visible, then the ease of operation is improved, but the adaptability deteriorates
Solution Approach 1:
The patent implements a dynamic cursor control system that adapts to different hand positions and gestures. The cursor position is continuously adjusted based on real-time detection of the object's height, movement, and hover gestures, allowing the system to flexibly accommodate various hand positions and interaction styles without restricting adaptability.
3Ease of operation
If sensor-based solutions are used to detect gestures off-screen, then the ease of operation is improved, but the device complexity increases
Solution Approach 1:
The patent makes the existing touch-sensitive display surface multi-functional by enabling it to detect both touch and hover gestures. The same display hardware that traditionally only detected touch is now configured to detect height information and hover gestures, eliminating the need for separate sensor systems and reducing overall device complexity while improving ease of operation.

AI summary
Operation of a user interface of a device that has a hover and touch sensitive display device includes receiving user information from the hover and touch sensitive display device and detecting that the received information corresponds to a hover control gesture, wherein the hover control gesture comprises a swipe gesture followed by hover information. In response to the detecting, the device is operated in a hover control mode that comprises using continuously supplied hover information to control placement of a cursor display on the hover and touch sensitive display device.
