Scribble Pattern Recognition for Quick App Access on Locked Devices
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Users face inconvenience in accessing features of locked electronic devices, as they need to perform multiple steps or unlock the device for functions that require authentication, such as camera or calculator, which can be awkward and time-consuming.
Innovation Solution
A system that allows users to access specific applications on a locked electronic device by drawing recognizable scribbled patterns on the screen, eliminating the need for multiple steps or unlocking the device, and enabling access to functions like camera, calculator, or other apps without authentication, using a customizable pattern recognition system.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If users unlock the device to access functions, then access to authenticated functions is enabled, but the number of steps increases and convenience decreases
Solution Approach 1:
The patent segments the device lock into two levels: a full lock requiring password authentication, and a partial unlock that allows access to specific applications without full authentication. This segmentation enables users to quickly access certain functions (camera, calculator, flashlight) by drawing patterns on the locked screen, while maintaining security for authenticated functions.
Solution Approach 2:
The system performs preliminary authentication through pattern recognition before full device unlock. Users draw patterns on the locked screen as a preliminary action that grants immediate access to specific applications, eliminating the need to perform the full unlock sequence for these functions.
2Productivity
If users draw patterns on locked screen, then quick access to specific apps is enabled, but system complexity increases
Solution Approach 1:
The pattern recognition system acts as an intermediary between the locked screen and application access. Instead of implementing a completely new authentication mechanism, the system uses the existing locked screen as an intermediary surface for pattern drawing, which then triggers selective app access without requiring full device unlock.
Solution Approach 2:
The system creates a simplified copy of the authentication process specifically for quick-access applications. Rather than requiring the full password authentication sequence, the system implements a simplified pattern-drawing copy that provides sufficient security for non-sensitive apps while dramatically reducing access time.

AI summary
A non-transitory machine-readable storage medium, having encoded thereon program code is provided. When the program code is executed by a machine, the machine implements a method for operating an application on an electronic device without having to perform numerous steps to access the predetermined feature after unlocking the device for functions that require authentication. The method includes the steps of providing an electronic device requiring a password to unlock the device, the device having a screen, wherein the device is locked; receiving a first recognizable scribbled pattern on the screen, the pattern being provided by a user, wherein the first recognizable scribbled pattern is associated with a first specific application; and unlocking only the specific application for use by the user.
