Virtual Desktop Multimedia Redirection via Mobile QR Scanning
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Users accessing virtual desktops via client devices often lack built-in multimedia accessories, making it cumbersome to use multimedia features, especially in scenarios requiring frequent camera and microphone adjustments.
Innovation Solution
A virtual desktop client device employs image scanning techniques to redirect multimedia streams from nearby mobile devices, such as smartphones or tablets, using QR codes, allowing the client device to utilize these accessories without the need for pre-installed software, and also redirects multimedia output streams to the mobile device for playback.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If the client device is equipped with multimedia accessories, then multimedia capabilities are available, but the physical structure makes the multimedia capability cumbersome to use
Solution Approach 1:
The patent introduces a mobile device as an intermediary carrier for multimedia accessories. Instead of integrating camera and microphone directly into the client device, these accessories are mounted on a mobile device (smartphone or tablet) which then acts as a portable multimedia station. This intermediary approach allows the client device to access multimedia capabilities without being constrained by its own physical structure, resolving the contradiction between having multimedia capabilities and ease of operation.
2Ease of operation
If the client device lacks built-in multimedia accessories, then the device structure remains simple, but multimedia activities cannot be performed
Solution Approach 1:
The patent makes the mobile device universal by enabling it to serve multiple functions: it remains a standalone communication device while simultaneously functioning as a multimedia accessory carrier for the client device. The mobile device's camera and microphone can be shared with the virtual desktop, allowing a single device to fulfill multiple roles and eliminating the need for the client device to have built-in multimedia accessories.
3Adaptability or versatility
If multimedia accessories are integrated into the client device, then multimedia functionality is available, but frequent movement of camera and microphone becomes necessary
Solution Approach 1:
The patent transitions the multimedia accessory placement from the client device's fixed physical location to a mobile device that operates in a different spatial dimension - a portable, independently movable platform. This dimensional change allows the multimedia accessories to be repositioned by moving the mobile device itself rather than adjusting components on the client device, significantly reducing the time and effort required for repositioning during multimedia activities.

AI summary
A system for multimedia redirection where a virtual desktop client device can utilize the multimedia accessories such as digital camera(s) and/or microphone(s) of nearby mobile devices by utilizing image scanning techniques. The mobile device contains a web browser and image scanning technology, such as a QR code reader. The mobile device scans a QR code displayed by the virtual desktop client device and establishes a connection with a web server on the virtual desktop client device. The multimedia stream captured by the multimedia accessories of the mobile device is streamed to the virtual desktop client device using the connection and is redirected by the virtual desktop client device to the virtual desktop. The virtual desktop client device may also redirect multimedia, such as an audio-out stream received from the virtual desktop, to the mobile device in order to playback audio using the speaker of the mobile device.
