Ingescape is used in many different contexts extending from R&D activities to fully operational solutions.

RATP
This is a “real world” operational project involving active communication with critical rail systems. It introduces innovative paperless multitouch interactive workstations enabling to command and control operational equipments and to monitor all the human and train resources for the exploitation of the train line. It can be seen as a combination of a large IoT network and a Big Data system with lots of data sources to be merged in order to ensure proper situation awareness and control means for the operators.
Each workstation is composed of 5 applications running under Linux, 3 of them developed in C and the 2 others forming the graphical environment, in Qt/C++.
Massive communication flows are handled by the applications to:
This project has widely benefited from the iterative architecture and integration capabilities supported by Ingescape. Tests around connections and data exchange have started very early in the global process, enabling to quickly provide proof of concepts and to create a positive loop between engineering and UX design activites, one providing feedback to the other about opportunities and limits.
Logging and record capabilities as offered by Ingescape have been actively included in the project activities for archiving, training and technical validation.
Bouyer Industries
This operational project resulted in an ecosystem of applications dedicated to scheduling, monitoring and operating Public Announcement systems in all kinds of places (malls, train stations, schools, public places, etc.). Each site is equipped with various types of devices from speakers to command and monitoring boxes.
Ingescape was used to create two types of software agents :
The software proxies run on appliances based on Linux. The graphical applications run on Microsoft Windows (7, 8 and 10).
Redundancy between proxies is in place, based on Ingescape discovery mechanisms. Ingescape ensures the synchronization between the proxies and the various graphical applications that are used simultaneously and sometimes concurrently between operators.
The applications make use of a wide variety of IOP types, namely strings for text messages, raw data to exchange media files and media streams and numeric types for well-identified values (on/off commands, sound volume, presence monitoring, etc.).
ESTIA PEPPS
The multidisciplinary team from the PEPSS platform was interested in comparing 3 interaction modalities to achieve the task of controlling the engine power of an aircraft. We wanted to explore new digital interactions for this specific task. Three interactions were compared: the classical one using a physical throttle, an innovative one using a touch screen and a disruptive one using the grab specific gesture on a leap motion device. The flight simulation was provided by the open-source software Flight Gear.
The classic approach would have been to implement a hardcoded software prototype for our specific scenarios. But this kind of project needs to be carried out in an agile, iterative and multidisciplinary context and the system needs to be flexible enough to easily integrate the new use cases, design modifications and experimentation protocols, including at runtime. And in addition, the experimenters were ergonomic students without technical knowledge and development abilities.
As our developer team already uses Ingescape to develop interaction agents, including an UDP bridge to interact with Flight Gear, it was really easy to setup the experimentation by reusing these existing Ingescape agents, literally with no cost-time development. The students were autonomous in the solution design and experimentation control at runtime, using Ingescape Circle. That is a great example of Ingescape enabling the reuse of agents for a totally different usage than the initial one, thus saving development time, and also modifying and adjusting the behavior of the system in real time without any technical knowledge, thus giving the control to the experimenters.
