Multimedia Docking Device Application Switching via Data Transfer
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current systems for mobile terminals connected to vehicle-integrated devices face challenges in switching between applications safely and efficiently, particularly due to limited screen space and potential driver distraction during direct end-device operation.
Innovation Solution
A processor-controlled multimedia terminal connected to a multimedia docking device allows for remote-controlled switching between applications by storing and transferring application-specific data records, enabling simplified selection and management of applications on a larger, vehicle-adapted interface.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If application switching is performed directly on the mobile terminal with limited screen space, then the terminal can maintain simple operation, but the user cannot get a sufficient overview of running applications and the driver may be distracted
Solution Approach 1:
The patent extends the application switching interface from the two-dimensional mobile terminal screen to the vehicle's multimedia docking device display, effectively adding a spatial dimension to the interaction. This allows the driver to view and switch applications on a larger surface area while maintaining simple operation through the vehicle's existing control interface.
Solution Approach 2:
The vehicle's multimedia docking device acts as an intermediary between the driver and the mobile terminal applications. It receives application data from the terminal, displays it on a larger screen, and processes switching commands, thereby resolving the conflict between limited terminal screen space and the need for comprehensive application overview.
2Adaptability or versatility
If multiple applications are run in parallel on the smartphone, then more functions are available, but the processor cannot process them faster and more reliably
Solution Approach 1:
The system segments the application execution environment into two parts: the mobile terminal maintains a limited set of active applications for reliable processing, while the vehicle's multimedia docking device provides access to additional applications through the transferred data structure. This allows functional versatility without compromising processing reliability on the terminal.
Solution Approach 2:
The patent creates a universal application management system where the mobile terminal's application list is made accessible and controllable through the vehicle's multimedia system. This multi-functional approach allows the same application set to be managed both on the terminal and through the vehicle interface, providing flexibility without requiring multiple parallel instances on the terminal.
3Volume of moving object
If the mobile terminal screen and control buttons are small, then the terminal design remains compact, but switching between applications causes driver distraction
Solution Approach 1:
The vehicle's multimedia docking device serves as an intermediary that transfers the application interface from the small terminal screen to the larger vehicle display. This allows the terminal to remain compact while the driver interacts with applications through the larger, less distracting vehicle interface.
Solution Approach 2:
The system moves the application display from the two-dimensional terminal screen to the vehicle's display system, effectively utilizing the three-dimensional space available in the vehicle environment. This provides a larger display area without increasing the terminal size, reducing driver distraction while maintaining compact terminal design.

AI summary
In a processor-controlled multimedia terminal (2) that is connected to a processor-controlled multimedia docking device (3), a group comprising a plurality of application programs (4) is stored and made available for execution. The application programs (4) can run on the multimedia terminal (2) in the foreground or in the background. Only one application program (4a) of the group is executed in the foreground on the multimedia terminal (2) at one time. An application program (4a) can output data via a graphical user interface (2a, 12) while running in the foreground. While running in the background, however, an application program (4a) cannot output data via the graphical user interface. In the multimedia terminal (2), a memory area (5) is also provided, to which the application programs (4) have read and write access during execution thereof. An application-specific data set (6) is stored in the memory area (5) for each application program (4), said data set remaining in the memory area even after the respective application program (4a) has ended. A first application program (4a), during execution thereof in the multimedia terminal (2), reads the application-specific data sets (6) of the other application programs of the group (4) and stores them in a list (7). The list (7) is also transmitted to the multimedia docking device (3). Data for the application programs (4) contained in the list (7, 14) is displayed on the multimedia docking device (3). An application program is selected from the list (7, 14) as the second application program (4b). A switchover is then made in the multimedia terminal (2) from the execution of the first application program (4a) to an execution of the second application program (4b) by means of the multimedia docking device (3), wherein the execution of the first application program (4a) in the foreground on the multimedia terminal (2) is ended and the second application program (4b) is brought to run in the foreground.
