Stylus Screen-Share Facilitation via Intermediary Identifier
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Establishing screen-sharing between devices can be tedious and time-consuming for users, requiring navigation through multiple menus to identify and select the appropriate destination device.
Innovation Solution
A method using an intermediary input device, such as a stylus, to facilitate screen sharing by receiving an identifier for the screen-share destination device, detecting a screen-share initiating user input, and transmitting this identifier to the screen-share source device to establish a screen-share pairing.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If users navigate through multiple menus to identify and select the appropriate destination device for screen sharing, then the screen-sharing process can be completed, but the process becomes tedious and time-consuming
Solution Approach 1:
The patent introduces a camera as an intermediary device to facilitate screen sharing. The camera captures images of the destination device's display, which shows a QR code or identifier. This intermediary approach allows the source device to automatically identify and connect to the destination device without manual menu navigation, resolving the contradiction by simplifying the operation while maintaining accurate device identification
Solution Approach 2:
The destination device prepares its display in advance by showing a QR code or identifier that encodes its identification information. This preliminary action allows the source device to quickly capture and decode the identifier through the camera, eliminating the need for time-consuming manual selection processes while ensuring accurate device pairing
2Reliability
If users manually select destination devices through menus, then device selection can be made, but the risk of inadvertently selecting the wrong device increases
Solution Approach 1:
The camera acts as an intermediary that captures visual information (QR code or identifier) directly from the destination device's display. This visual intermediary approach ensures accurate device identification by using the destination device's own displayed identifier, eliminating manual selection errors while maintaining operational simplicity through automatic decoding and connection
Solution Approach 2:
The patent replaces the mechanical interaction of manual menu navigation and device selection with an optical system. The camera captures the destination device's displayed identifier, and the system automatically decodes and processes this visual information to establish the connection. This substitution eliminates human error in device selection while keeping the process simple and intuitive
Data Source
AI summary
A method for screen-share facilitation at an input device includes receiving, from a screen-share destination device, an identifier corresponding to the screen-share destination device. The input device detects a screen-share initiating user input to initiate screen sharing between the screen-share destination device and a screen-share source device, and transmits a screen-share initialization request to the screen-share destination device. The identifier of the screen-share destination device is transmitted to the screen-share source device to facilitate establishment of a screen-share pairing between the screen-share source device and the screen-share destination device. The screen-share pairing enables graphical content rendered by the screen-share source device to be displayed by the screen-share destination device.
