Dynamic Virtual Touchpad for Double-Sided Display Input
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
In electronic devices with double-sided display screens, the limited size of the virtual touchpad on the second screen causes users to frequently move their fingers outside its range, interrupting mouse cursor control operations, as the smooth display surface lacks a physical touchpoint for accurate cursor positioning.
Innovation Solution
A method and electronic device that continuously acquire input data and adjust the target region's range based on initial input position conditions to keep the input position within the adjusted range, preventing operation interruptions by enlarging or changing the target region dynamically according to user input tracks.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Measurement precision
If the virtual touchpad size is increased to improve input accuracy, then the available space for the virtual keyboard and other input elements is reduced
Solution Approach 1:
The touchpad region is made dynamic by continuously adjusting its range based on the user's input track. The system monitors the continuous input data and expands or contracts the touchpad region to keep the input position within bounds, transforming a static layout problem into a dynamic adaptation solution that resolves the space conflict.
Solution Approach 2:
The system changes the parameter of the touchpad region range in real-time based on the input track. By adjusting the range parameter dynamically according to user interaction patterns, the system optimizes both input accuracy and space utilization without requiring a fixed large touchpad area.
2Ease of operation
If the user focuses on the first screen to improve viewing experience, then the finger easily moves beyond the virtual touchpad range causing operation interruption
Solution Approach 1:
The system implements feedback by continuously monitoring the input position and comparing it with the touchpad region boundaries. When the finger approaches or exceeds the boundary, the system responds by adjusting the touchpad region range to accommodate the input track, ensuring operation continuity without requiring the user to maintain constant visual attention on the touchpad.
Solution Approach 2:
The system performs preliminary action by proactively adjusting the touchpad region range before the input operation is interrupted. By anticipating when the finger might move beyond the current boundaries and expanding the region in advance, the system prevents operation interruption rather than reacting after the problem occurs.
3Measurement precision
If the user frequently checks finger position to maintain operation accuracy, then the input efficiency is reduced due to multiple finger movements
Solution Approach 1:
The system provides self-service by automatically tracking and adjusting the touchpad region based on the user's input movements. Instead of requiring the user to consciously monitor and correct their finger position, the system autonomously adapts the touchpad boundaries to encompass the input track, eliminating the need for frequent position checks and multiple corrective movements.
Data Source
AI summary
A display method includes acquiring continuous input data input on an input apparatus of an electronic device and, in response to an input position of initial input data of the continuous input data satisfies a position condition during a process of continuously acquiring the continuous input data, adjusting a range of a target region on the input apparatus to keep an input position of the continuous input data within the range of the target region after being adjusted. The target region is configured to at least control a position of an indicator on a display apparatus of the electronic device.
