Stylus Pen Control for Background Application Selection
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Users face challenges in seamlessly controlling application programs running in the background on mobile communication terminals using a stylus pen, leading to degraded continuity and accessibility.
Innovation Solution
An electronic device with a touch screen and a paired stylus pen that supports Bluetooth communication, allowing users to execute and control multiple application programs with minimal user input by receiving signals from button presses or touches, enabling natural control of background applications.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If a user accesses a background application program through a separate menu, then the background application can be controlled, but the continuity and accessibility of the user are degraded
Solution Approach 1:
The system pre-associates the stylus pen with the background application program before the user needs to control it. When the stylus pen is detected, the system automatically establishes the control relationship, so the user does not need to perform menu navigation or switching actions, thus maintaining continuity and accessibility
Solution Approach 2:
The stylus pen acts as an intermediary device that enables direct control of the background application without requiring the user to switch to the application's interface or navigate through menus. The stylus pen transmits control signals that the system routes to the appropriate background application, preserving user flow and accessibility
2Adaptability or versatility
If multiple application programs are running in the foreground by multi-windows, then the user can access multiple applications, but the user cannot swiftly select and control one of them using a stylus pen
Solution Approach 1:
The system provides feedback by detecting which application program is currently in the background and automatically establishing the control relationship with that specific application. This feedback mechanism allows the user to swiftly select and control the intended application without manually navigating through multiple foreground windows, as the system self-identifies and connects to the correct target application

AI summary
An electronic device is disclosed. The disclosed electronic device comprises: a touch screen display structure; a first wireless communication circuit; a second wireless communication circuit; a stylus pen including at least one button which can be pressed or touched; a processor operationally connected to the touch screen display structure and the first wireless communication circuit; and a memory operationally connected to the processor. A first application program including a first user interface, and a second application program including a second user interface are stored in the memory. The memory has instructions stored therein which are configured to cause, when executed, the processor to: execute the first application program and second application program when a user input is received; display at least one of the first user interface and second user interface by means of the touch screen display structure; receive a first signal, which is generated by the press or touch of the button for a first time period, from the stylus pen through the first wireless communication circuit; select one from the first application program and second application program on the basis of the first signal; change at least part of information displayed on the screen, at least partly on the basis of the selection; receive a second signal, which is generated by the press or touch of the button for a second time period different from the first time period, from the stylus pen through the first wireless communication circuit; and at least partly on the basis of the selection, perform a function of the first application program or a function of the second application program in response to the second signal. Various other embodiments are possible.
