Touch Display Interaction Interface for Simultaneous Presentation and Input
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current touch displays with touch capabilities become unavailable when connected to a laptop for presentations, limiting their functionality to regular display mode, thus hindering interactive capabilities during local or remote video meetings.
Innovation Solution
An interaction interface device that enables communication between a touch display unit and an external device, allowing for the reception and transmission of touch data and video data between the two, enabling full utilization of the touch display even during presentations by creating a sub-portion for interaction and processing touch gestures for seamless integration with external devices.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If a touch display is connected to a laptop for presentations, then the display can show presentations, but the touch capability becomes unavailable
Solution Approach 1:
The display area is segmented into multiple independent regions, each capable of receiving and processing touch inputs separately. This allows different portions of the display to serve different functions simultaneously - some areas for presentation content while others maintain touch interactivity, resolving the contradiction between presentation mode and touch capability availability
Solution Approach 2:
The interaction interface device enables the display to serve multiple functions simultaneously - it can display presentations while also accepting touch inputs, and can route these inputs to different applications or regions. This multi-functionality allows the display to adapt to both presentation and interactive needs without requiring separate devices or complex reconfiguration
2Area of stationary object
If the touch display is used in full screen mode for presentations, then the presentation can be displayed, but the touch interaction is limited or unavailable
Solution Approach 1:
Different regions of the display are assigned different functional qualities - some areas are optimized for presentation display while others are designated for touch interaction. This local differentiation allows the display to maintain both full-screen presentation capability and touch interaction capability simultaneously, with each region having the appropriate characteristics for its intended use
3Adaptability or versatility
If touch data is transmitted between the touch display and external device, then interaction is enabled, but data processing and positioning complexity increases
Solution Approach 1:
The interaction interface device acts as an intermediary between the touch display and the external device, managing the complex data processing and coordinate transformation tasks. This mediator handles the routing of touch data to appropriate applications, performs necessary coordinate transformations, and manages the communication protocols, thereby enabling interaction capability while containing the processing complexity within a dedicated interface component
