Wireless Screen Sharing Destination Verification via Confirmation Image
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing screen sharing technologies via wireless networks do not provide a method for users to confirm the correct destination apparatus before initiating screen transmission, leading to potential unintended image sharing with undesirable reception apparatuses.
Innovation Solution
A communication apparatus that includes a display unit, a first transmission unit for displaying a confirmation image on the destination apparatus, and a selection unit allowing users to verify and confirm the transmission destination before sharing the screen, ensuring accurate selection through a user-operated process.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If automatic wireless network connection is established without password authentication, then ease of operation is improved, but reliability deteriorates due to inability to confirm transmission destination
Solution Approach 1:
The system performs preliminary action by displaying a confirmation image on the reception apparatus before actual screen sharing begins. This confirmation image allows the user to verify the transmission destination in advance, ensuring reliability while maintaining automatic connection convenience.
Solution Approach 2:
The system implements feedback by transmitting a confirmation image from the transmission apparatus to the reception apparatus, and then transmitting a selection result back to the transmission apparatus. This feedback loop enables the user to confirm the transmission destination and provides a mechanism to prevent unintended screen sharing.
2Reliability
If confirmation image transmission is added to verify destination, then reliability is improved, but device complexity increases
Solution Approach 1:
The system uses copying by transmitting a confirmation image that replicates or represents the transmission destination information to the reception apparatus. This simple copying mechanism provides reliable destination verification without requiring complex additional hardware or processing systems.

AI summary
A communication apparatus displays an image on a display unit, transmits a display image displayed on the display unit to another communication apparatus by wireless communication, transmits a confirmation image for confirming a transmission destination of the display image to the another communication apparatus by wireless communication to display the confirmation image on the another communication apparatus, selects, by a user operation, whether to transmit the display image to the another communication apparatus, after transmission of the confirmation image and before transmission of the display image, and transmits the display image to the another communication apparatus if it is selected in the selecting to transmit the display image.
