Virtual Keypad on Touch Screen for Input Efficiency
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Users of touch-screen notebooks experience strained arms and low input efficiency due to the need to frequently switch between touching the screen and tapping the physical keypad for data input, especially when inputting small amounts of data.
Innovation Solution
An electronic device with a touch sensing unit and display unit that determines the operation mode and selectively pops up a soft keypad on the screen for data input, allowing users to input data directly via the touch screen without physically using the keypad when the amount of data is small, thereby reducing hand movement and improving efficiency.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Measurement precision
If a physical keypad is used for data input on a touch-screen notebook, then input precision is improved, but ease of operation deteriorates due to frequent switching between screen and keypad
Solution Approach 1:
The patent creates a virtual copy of the physical keypad as a soft keypad displayed on the touch screen. This soft keypad replicates the input functionality of the physical keypad while being integrated into the touch screen interface, allowing users to input data with precision without leaving the screen. The soft keypad is constructed based on the current application context and displayed at an appropriate position on the screen.
Solution Approach 2:
The patent merges the input functions of both the physical keypad and touch screen into a unified interface. By displaying the soft keypad on the touch screen and enabling switching between physical and virtual input modes, the system combines the precision of physical key input with the convenience of touch screen operation, eliminating the need to switch between separate devices.
2Ease of operation
If a soft keypad is always displayed on the touch screen, then ease of operation is improved, but device complexity increases
Solution Approach 1:
The patent implements a dynamic soft keypad that adapts to different input scenarios. The soft keypad is not always displayed but is constructed and shown only when needed, based on the current application context and input requirements. The system dynamically determines whether to display the soft keypad, what keys to include, and where to position it, reducing unnecessary interface elements and improving clarity.
Solution Approach 2:
The patent applies local quality by customizing the soft keypad content and position based on the specific input context. Different applications or input scenarios receive tailored soft keypads with relevant keys displayed in appropriate locations. This contextual adaptation ensures the soft keypad provides assistance where needed without adding complexity to unrelated interfaces.
3Adaptability or versatility
If the soft keypad is constructed based on current input context, then adaptability is improved, but device complexity increases
Solution Approach 1:
The patent performs preliminary analysis of the input context before constructing the soft keypad. The system pre-processes information about the current application, input field requirements, and user needs to determine the appropriate soft keypad configuration. This preliminary action enables the soft keypad to be highly adaptive to different scenarios while using systematic rules to manage the complexity of context analysis.

AI summary
The disclosure provides an information processing method. The method includes: detecting a first input operation by a touch sensing unit; determining whether a first condition is satisfied; executing a first instruction set if it is determined that the first condition is satisfied; and executing a second instruction set different from the first instruction set if it is determined that the first condition is not satisfied, the first instruction set includes at least a first display instruction for displaying an array of input identities by a display unit which is overlapped with the touch sensing unit, and the array of input identities includes at least one input identity, the input identity being an identity which is capable of being triggered by a second input operation detected by the touch sensing unit in order to input data corresponding to the input identity. The method can make input operations more convenient.
