Smart Device Multitasking Control via Overlay Interface
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing smart devices require users to switch between main and background applications, causing inconvenience when multitasking, especially when controlling background programs like navigation, as it disrupts the main application screen and user experience.
Innovation Solution
A multitask-controllable smart device and method that overlays a second application control screen on a first application running screen, splits it into transparent and non-transparent sections, allowing input signals through either screen to control the second application without interfering with the first application, enabling seamless multitasking.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If the main program running screen is changed to the screen of the background program to control it, then the background program can be controlled, but the main application screen is disrupted and user experience deteriorates
Solution Approach 1:
The control screen is divided into a first screen and a second screen. The first screen allows control of the background program while the second screen maintains the main application display, enabling simultaneous access to both functions without disrupting either.
Solution Approach 2:
The solution transitions from a single-screen interface to a multi-screen overlay interface. The control screen is positioned in a specific region (e.g., bottom or side) while the main application occupies the primary display area, creating a spatial dimension that accommodates both functions simultaneously.
2Loss of information
If the control screen is made fully transparent to maintain main application visibility, then the main application can be viewed, but the control interface becomes difficult to interact with
Solution Approach 1:
Different regions of the control screen have different transparency properties. The first screen region has higher transparency to maintain main application visibility, while the second screen region has lower transparency to improve control interface visibility and interaction.
3Adaptability or versatility
If multiple applications are run simultaneously, then multitasking capability is improved, but the complexity of controlling background programs increases
Solution Approach 1:
The system automatically manages the overlay control screen based on detected user input. When input is detected, the control screen is displayed; when no input is detected for a predetermined time, it is hidden. This automatic management reduces the complexity of manual control switching.
Solution Approach 2:
The control screen's visibility and position are dynamically adjusted based on user interaction. The screen can be hidden or displayed according to input detection, and its position can be changed to optimize the user experience during multitasking operations.

AI summary
Disclosed are a smart device capable of multi-tasking control, capable of controlling a multi-tasking program while a main program screen is viewed, and a control method therefor. The smart device capable of multi-tasking control and the control method therefor can control a second program without being disturbed by the use of a first application and have the advantages of easily controlling a second application due to a wide input range since a user uses the entire screen, and enabling the user to control two applications, as necessary, since the overlay state of a first screen can be changed using only a simple input signal.
