Touchscreen State Switching via Translation Input Loci
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing electronic devices lack an efficient method to switch between locked and unlocked states based on user input characteristics, particularly using translation inputs, which can lead to user frustration and increased input actions.
Innovation Solution
A computing device that utilizes predefined loci on a touchscreen or display to determine the start and end points of a translation input, switching states based on these inputs, allowing users to unlock the device by dragging an icon or other elements between specific areas, thereby enabling or disabling functions.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If traditional button presses or password entry methods are used to switch between locked and unlocked states, then security is maintained, but the number of user input actions increases and user experience deteriorates
Solution Approach 1:
The system performs preliminary analysis of the translation input characteristics (distance, direction, velocity) before executing the state switch. By pre-defining loci and criteria for state transitions, the device can quickly determine whether to unlock without requiring multiple sequential actions from the user, thus reducing time loss while maintaining security through characteristic verification.
Solution Approach 2:
The patent replaces traditional mechanical interaction methods (physical buttons, keyboard typing) with a touchscreen translation gesture system. This substitution allows users to unlock the device through a continuous drag motion rather than discrete button presses or password entry, significantly reducing the number of input actions and time required while maintaining security through gesture characteristic analysis.
2Productivity
If multiple discrete input actions are required to unlock the device, then security is enhanced, but user frustration increases and productivity decreases
Solution Approach 1:
The system merges multiple security verification steps into a single continuous translation gesture. Instead of requiring separate actions for different security checks, the device combines distance verification, direction validation, and velocity analysis into one unified drag operation, thereby increasing productivity while maintaining security through multi-parameter gesture analysis.
Solution Approach 2:
The translation gesture system serves multiple functions simultaneously: it acts as both the unlock trigger and the security verification mechanism. The same gesture that initiates unlocking also provides the characteristics (distance, direction, velocity) used for security validation, eliminating the need for separate input sequences and simplifying user interaction while maintaining security.
3Reliability
If the device requires precise password entry or multiple button presses, then security is improved, but the number of input actions increases and user experience worsens
Solution Approach 1:
The patent extracts the security verification function from traditional multi-step input mechanisms (password keyboards, multiple buttons) and embeds it within the characteristics analysis of a single translation gesture. By taking out the sequential verification steps and integrating them into continuous gesture parameter monitoring, the system maintains reliability through multi-factor authentication while reducing device complexity by eliminating separate input mechanisms.

AI summary
Based on one or more characteristics of a received translation input, a computing device is switched between two or more states. The translation input may be a touch input, for example a drag operation. The states may relate to locked and unlocked states, idle screens, or other suitable examples.
