Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current communication systems fail to effectively replicate physical interactivity in meetings, as they often distract participants with cumbersome manual tasks and lack the dynamic movement and writing capabilities of traditional paperboards, leading to reduced focus and loss of information context.
Innovation Solution
A communication system featuring a display screen with capacitive and infrared sensors to detect finger and object positions, allowing for natural writing and movement functions without requiring users to switch modes, integrated with a computer program to manage and project images, enabling a seamless and interactive experience akin to traditional paperboards.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Extent of automation
If a touch screen with digitizing tablet is used to enable writing and selection functions, then data processing capability is improved, but the natural physical interactivity of moving objects with hands is lost
Solution Approach 1:
The patent uses a camera to capture images of physical objects (papers, whiteboards, blackboards) and displays them on a touch screen, creating a digital copy that preserves the physical appearance while enabling automated processing. This allows users to interact with familiar physical-like interfaces while benefiting from digital capabilities.
Solution Approach 2:
The camera acts as an intermediary between physical objects and the digital display system. By capturing physical objects and projecting them onto the touch screen, the system mediates between the natural physical interaction users desire and the automated data processing capabilities needed, enabling both writing and movement functions naturally.
2Loss of information
If manual tasks such as tearing and scanning paper are required, then information capture is achieved, but participant concentration and meeting efficiency are reduced
Solution Approach 1:
The camera is positioned to continuously capture or pre-capture images of physical objects before they are moved or manipulated. This preliminary capture action ensures information is already digitized and ready for display, eliminating the need for manual scanning operations during the meeting and maintaining participant focus.
Solution Approach 2:
The system automatically captures images of physical objects using the camera and displays them on the touch screen without requiring manual intervention. The camera and processing system serve themselves by automatically detecting, capturing, and displaying information, freeing participants from manual scanning tasks.
3Reliability
If a frozen state storage of documents is used, then information preservation is achieved, but the dynamics and context leading to the final state are lost
Solution Approach 1:
The system continuously captures images of physical objects as they are manipulated throughout the meeting, creating a continuous visual record rather than static snapshots. This continuous capture preserves the dynamics and evolution of information while maintaining reliable storage of the final state, as the sequence of images records the contextual development.
Solution Approach 2:
The system transitions from static document storage to dynamic image capture, where the camera continuously records the movement and manipulation of physical objects. This dynamic approach preserves the contextual information and evolution of ideas while still providing reliable preservation of final states through stored images.

This section explains which scientific principles are used to turn an abstract innovation direction into a practical engineering solution.
Function Achieved in This Case
Enhances meeting efficiency by allowing participants to engage in bodily and cerebral actions, capturing relevant information naturally without distractions, and storing interactions for future reference, thus enriching the exchange and reflection process.
Implementation Method 1
by measuring a physical quantity which varies according to a contact of the human finger on the screen
Implementation Method 2
A second device arranged to detect a position of at least one object on the screen distinctly from a position of a human finger

AI summary
To reproduce an interactivity of physical type between at least two parties or participants in a meeting, the system comprises at least one display screen (20, 21, 22) which comprises a first device arranged so as to detect at least one position of a human finger by measuring a first physical quantity which varies as a function of a human finger contact on said screen (20, 21, 22), and a second device arranged so as to detect at least one position of an object (30, 31, 32) equipped in such a way as to emit a uniform signal, by measuring a second physical quantity related to a reception of said uniform signal which varies as a function of the position of the object (30, 31, 32) with respect to the screen (20, 21, 22). A computer (10, 11, 12) of the system, configured to receive the human finger's position detected by the first device and the object's position detected by the second device, is programmed to allocate an area of the screen (20, 21, 22) for writing, so as to modify, in the area allocated for writing, a local visual aspect which follows the position of the object (20, 21, 22) on the screen when the object emits the uniform signal and to vary the area allocated for writing as a function of a displacement related to the position of the human finger on the screen (20, 21, 22).
