Cloud-Based Device Handoff for Seamless Content Switching
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing personal area networks (PANs) do not seamlessly allow users to access and switch between multiple devices, such as smartphones and laptops, for continuous multimedia sessions without manual intervention, limiting user experience and convenience.
Innovation Solution
A cloud-based service that creates a network of interconnected devices using a peer table and service module, enabling context handoffs and seamless access to applications and content across devices, with features like battery management for streaming media sessions.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If content is downloaded directly to a given device, then the user can access the content on that device, but the user is limited in being able to access the content unless the user has physical access to the given device that stores the desired content
Solution Approach 1:
The patent introduces a cloud server as an intermediary that stores content and manages device connections. The cloud server enables users to access content from multiple devices without physically possessing the original device, by acting as a central repository and routing mechanism that mediates between the user and various devices in the network.
Solution Approach 2:
The system enables a single content item to be accessed universally across multiple different devices (smartphone, tablet, laptop, etc.). The cloud-based architecture allows the same content to be retrieved and displayed on any device within the user's network, making the content access system multi-functional and device-agnostic.
2Ease of operation
If a user switches from one device to another to access content, then the user can use a more convenient device, but the user must proceed through several manual steps including login, accessing browser, entering address, and scrolling to resume access
Solution Approach 1:
The system performs preliminary actions by automatically maintaining session state, authentication tokens, and content position information in the cloud before the user actually switches devices. When the user switches to a new device, these pre-prepared information elements are automatically transferred, eliminating the need for manual login, address entry, and navigation steps.
Solution Approach 2:
The system implements feedback mechanisms where the cloud server continuously tracks and stores information about the user's current session state, including content position, playback position in videos, and browsing context. This feedback information is automatically retrieved when the user connects from a different device, enabling seamless resumption without manual intervention.
3Duration of action of stationary object
If streaming media sessions continue on a device with low battery, then the session can be maintained, but the device may run out of power and cause interruption
Solution Approach 1:
The system uses feedback from battery status monitoring to automatically detect when a device's power level is becoming critically low. This feedback triggers an automated handoff process that transfers the streaming session to another device in the network with sufficient power, preventing interruption and maintaining session stability.
Solution Approach 2:
The system performs preliminary battery status checks and proactively initiates session handoff before the device actually runs out of power. By monitoring battery levels in advance and pre-coordinating the transfer of streaming sessions to backup devices, the system ensures continuous playback without interruption or loss of session state.
Data Source
AI summary
In aspects of the disclosed technology, a processor receives a message containing updated content information and updated state information relating to an application of a first device and updates a peer table to reflect the updates. The processor outputs a message containing information related to the updated content and updated state to a second device, the message configured to cause the second device to update its lock screen to reflect the updated state information. The processor further updates the peer table upon receiving an update from the second device indicating that a user of the second device has selected the application. Finally, the processor outputs updated peer information to the first device that causes the first device to end content associated with the updated content information.
