Dynamic Unlocking Objects on Touch Displays
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional methods for unlocking electronic devices with touch screens are often complicated and not user-friendly, leading to unintentional activation or deactivation of functions due to unintentional contact.
Innovation Solution
A method where unlocking objects on a touch-sensitive display are dynamically displayed at different locations for different time points, allowing the device to determine whether to unlock based on contact status without pre-defined passwords or gestures, using a program code that controls the display and processes touch inputs.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If conventional unlock procedures (pre-defined passwords, buttons, gestures, locations) are used, then the device can be unlocked reliably, but the procedure becomes complicated and not user-friendly
Solution Approach 1:
The patent applies dynamics by making the unlocking objects mobile rather than static. The unlocking objects move to different locations on the touch-sensitive display at different time points, transforming the conventional static unlock method into a dynamic one. This resolves the contradiction by maintaining reliability through controlled movement patterns while improving ease of operation through more natural and flexible interaction.
Solution Approach 2:
The patent implements periodic action by having unlocking objects appear at different locations at different time points in a systematic sequence. This periodic repositioning creates a time-based interaction pattern that is both reliable (follows predictable rules) and user-friendly (allows natural touching motion), resolving the contradiction between reliability and ease of operation.
2Reliability
If the device is locked automatically to avoid unintentional activation, then function activation reliability improves, but the unlocking process becomes more complex
Solution Approach 1:
By making unlocking objects dynamic and mobile rather than static at pre-defined locations, the patent reduces the need for complex pre-defined gestures and passwords. The objects move to different locations at different time points, creating a more intuitive interaction that maintains security while reducing procedural complexity.
3Ease of operation
If unlocking objects are displayed at pre-defined locations, then the unlock procedure is simple, but unintentional contact may still activate functions
Solution Approach 1:
The patent resolves this contradiction by making unlocking objects mobile rather than static. Objects are displayed at different locations at different time points, which maintains simplicity for the user (who just needs to touch any object) while preventing unintentional activation (since objects move away from predictable locations).
Solution Approach 2:
The system takes preliminary anti-action by proactively moving unlocking objects to different locations before the user can accidentally trigger them. This anticipatory movement prevents unintentional activation while keeping the interaction simple - the user just touches wherever an object appears.

AI summary
A method of unlocking an electronic device having a touch-sensitive display includes at least the following steps: controlling the touch-sensitive display to have unlocking objects displayed at different locations for different time points; and when at least one contact is detected on the touch-sensitive display, determining whether to unlock the electronic device by referring to a contact status on the touch-sensitive display. Besides, a computer readable medium storing a program code is also provided, where the program code causes a processor to perform following steps when executed by the processor: controlling the touch-sensitive display to have unlocking objects displayed at different locations for different time points; and when at least one contact is detected on the touch-sensitive display, determining whether to unlock an electronic device by referring to a contact status on the touch-sensitive display.
