Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing online learning solutions fail to effectively combine small-screen and large-screen devices, resulting in insufficient interaction and poor user experience due to small screens and limited vision.
Innovation Solution
A multi-device-based online interaction method that allows content to be hopped between electronic devices for playing and interaction, with control instructions transmitted via distributed soft buses, enabling seamless interaction and feedback between devices.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Area of stationary object
If content is simply copied from handheld terminal to large screen using DLNA or Miracast protocol, then content can be displayed on large screen, but the two devices cannot effectively combine their advantages and interaction remains weak
Solution Approach 1:
The system divides the functional roles between devices: the large screen device handles content display while the handheld terminal handles interaction operations. This segmentation allows each device to optimize its strengths - the large screen provides immersive visual experience while the handheld device provides convenient interaction, resolving the contradiction between display area and interaction capability.
Solution Approach 2:
The patent introduces a soft bus as an intermediary communication mechanism between the handheld terminal and large screen device. This soft bus enables bidirectional communication and coordination, allowing the devices to work together as a unified system rather than simple content copying, thereby enhancing interaction capability while maintaining large screen display advantages.
2Ease of operation
If online learning is conducted on handheld terminal with small screen, then portability is maintained, but vision loss occurs due to short line of sight and interaction is insufficient
Solution Approach 1:
The system transitions from a single-device paradigm to a multi-device spatial arrangement. The handheld terminal remains portable and close to the user, while the large screen device is positioned at an appropriate viewing distance. This spatial dimensionality change allows the user to maintain portability benefits while accessing the large screen for improved visual experience during online learning.
3Adaptability or versatility
If multi-device collaboration is implemented, then device capabilities can be combined, but system complexity increases
Solution Approach 1:
The soft bus is designed as a universal communication interface that can handle multiple types of interactions and coordinate various device functions. This multi-functional communication mechanism simplifies the overall system architecture by providing a single standardized interface for device collaboration, thereby reducing system complexity while maintaining high adaptability and versatility.

AI summary
Embodiments of this application provide a multi-device-based online interaction method, and relate to the field of terminals. A first electronic device starts a first application to play first playing content. When the first electronic device receives a control instruction for hopping the first playing content of the first application to a second electronic device, the first electronic device sends a hopping message to the second electronic device. When the second electronic device receives the hopping message, the second electronic device continues to play the first playing content. In response to a control starting instruction transmitted by a content provider server, the first electronic device starts an interaction control. The first electronic device obtains interaction information of the interaction control, and sends the interaction information to the content provider server.
