Wearable Audio Handoff for Seamless Cross-Device Playback
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Users experience a disruption in immersive experience when they need to leave a room while watching a video or listening to audio on a smart device, leading to a poor user experience.
Innovation Solution
A method involving a wearable device that sends the MAC address of a paired mobile device to a remote control device, which then relays playback information to the mobile device to resume audio playback using the wearable device.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If the user leaves the room while playback is ongoing on an electronic device, then the user's attention shifts to reality, but the playback cannot be continued, resulting in broken immersion
Solution Approach 1:
The patent introduces a wearable device as an intermediary between the electronic device and the user's auditory system. When the user leaves the room, the wearable device receives playback information from the electronic device and continues playing the audio locally, serving as a mediator that maintains the audio stream independent of the user's physical presence in the room.
Solution Approach 2:
The system performs preliminary actions by pre-establishing the wearable device's capability to receive and play audio content before the user actually leaves. The electronic device sends playback information in advance, and the wearable device is ready to immediately take over playback, ensuring seamless continuity without interruption when the user moves away.
2Reliability
If the wearable device receives playback information, then audio playback can resume seamlessly, but additional devices and communication protocols are required
Solution Approach 1:
The wearable device is designed with multi-functionality, serving both as a regular audio playback device and as a mobile endpoint for receiving playback information from electronic devices. This universal design allows the same device to function in multiple contexts without requiring separate specialized hardware, thereby managing complexity while ensuring reliability.
3Adaptability or versatility
If playback information is sent to the mobile device, then the audio can be resumed on the wearable device, but data transmission and device coordination are required
Solution Approach 1:
The mobile device acts as an intermediary communication node between the electronic device and the wearable device. It receives playback information from the electronic device, processes the data, and forwards it to the wearable device, simplifying the communication architecture by breaking down complex direct device-to-device protocols into manageable segments through a familiar mobile device interface.
Data Source
AI summary
This application provides a method for continuing playback of audio. In the method, a wearable device can send a MAC address of a mobile device paired with the wearable device to a remote control device, the remote control device sends the MAC address of the mobile device to an electronic device, the electronic device sends playback information of current playback content on the electronic device to the mobile device based on the MAC address of the mobile device, and the mobile device can resume playing, based on the playback information, an audio of the playback content that is being played on the electronic device.
