Sliding Keyboard Access for Portable Devices
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Portable electronic devices with touch-sensitive displays face challenges in providing efficient access to applications while maintaining security and minimizing user input complexity, especially in locked states where limited functionality is required.
Innovation Solution
A method and device configuration that detects specific events on a touch-sensitive display, allows selection of options, and performs associated functions by sliding a keyboard portion relative to the display, enabling single-interaction access to applications without fully unlocking the device.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If the device requires full unlocking to access applications, then security is improved, but user convenience and access speed deteriorate
Solution Approach 1:
The patent segments the access control mechanism into two distinct modes: full unlock mode for complete access and locked mode for restricted access. In locked mode, specific applications can be accessed through alternative mechanisms (such as biometric authentication or pre-set shortcuts) without requiring the full unlock sequence, thus segmenting the authentication requirements by application criticality.
Solution Approach 2:
The system performs preliminary authentication for frequently accessed applications even when the device is locked. By pre-configuring trusted applications and pre-establishing authentication methods (such as fingerprint or facial recognition), the system enables rapid access to essential functions without requiring the user to go through the complete unlock process each time.
2Reliability
If multiple input steps are required to access applications in locked state, then security is improved, but operation complexity and time consumption increase
Solution Approach 1:
The patent implements partial authentication actions for locked state access. Instead of requiring the complete multi-step unlock sequence, the system accepts simplified authentication inputs (such as a single fingerprint scan or a predefined gesture) that provide sufficient security for locked-mode applications while significantly reducing the time and number of steps required compared to full unlocking.
3Adaptability or versatility
If the keyboard portion is made movable relative to the display, then input flexibility is improved, but device complexity increases
Solution Approach 1:
The patent makes the keyboard portion dynamically movable relative to the display through a sliding mechanism. The keyboard can transition between different positions (retracted and extended) along the vertical axis, allowing it to adapt to different usage scenarios. This dynamic configuration enables the keyboard to be pulled down for typing tasks and retracted for viewing tasks, providing input flexibility without requiring complex mechanical structures.

AI summary
A method of providing access to an application from a portable electronic device is provided. The method includes detecting an event to provide a selectable option, identifying a selectable option associated with the event and providing the selectable options on a touch-sensitive display of the portable electronic device, and in response to detecting a touch associated with the selectable option on the touch-sensitive display and movement of a keyboard portion of the portable electronic device relative to the touch-sensitive display, performing a function associated with the selectable option.
