Virtual Interface Offset Using Palm Input Patterns
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Touch devices lack tactile feedback, leading to difficulties in accurately entering information due to finger drift and position misalignment on virtual interfaces, which current solutions like continuous finger tracking or adjusting finger positions on the screen do not adequately address, especially during prolonged use.
Innovation Solution
The system detects palm input patterns and adjusts the virtual interface accordingly, using palm data to anticipate and correct finger positions dynamically, allowing for more accurate and efficient input without requiring continuous user attention.

Engineering Contradiction Analysis
1Volume of moving object
If a virtual interface is used on a touch surface, then device portability and integration are improved, but input accuracy and user control deteriorate due to lack of tactile feedback
Solution Approach 1:
The patent introduces an intermediary system that uses palm detection algorithms to interpret the user's intent based on palm position and orientation on the touch surface. This intermediary layer translates physical palm placement into virtual interface adjustments, bridging the gap between touchless interaction and precise input control.
Solution Approach 2:
The system implements feedback by continuously monitoring palm position and dynamically adjusting the virtual interface layout accordingly. This creates a closed-loop system where the interface responds to user posture, providing adaptive feedback that compensates for the lack of tactile confirmation and improves input accuracy.
2Measurement precision
If the virtual interface is adjusted dynamically based on palm position, then input accuracy is improved, but system complexity increases
Solution Approach 1:
The system employs self-service by using the user's own palm as the reference frame for interface adjustment. The palm detection algorithm automatically identifies palm characteristics and uses them to configure the virtual interface, eliminating the need for manual calibration or complex external sensing systems.
Solution Approach 2:
The palm detection system serves multiple functions: it detects palm position, determines palm orientation, identifies user intent, and triggers interface adjustments. This multi-functionality reduces the need for separate systems for each task, thereby managing complexity while improving input accuracy.
3Measurement precision
If continuous finger tracking is implemented to correct finger drift, then input accuracy is improved, but ease of operation deteriorates due to increased user attention requirements
Solution Approach 1:
The system performs preliminary action by adjusting the virtual interface proactively based on palm position before the user actually attempts input. By anticipating where the user intends to type based on palm placement, the system pre-configures the interface to match the user's natural finger positioning, preventing drift rather than correcting it.
