• KIWI Music: the KIWI Team is developing an online music recommender system as an evaluation framework for recommender algorithms.
  • Dr Sport: Dr Sport is the first full service dedicated to diagnosis of sport pathologies (from the analysis of the pathology to the orientation towards the nearest competent professionals). It relies on Artificial Intelligence techniques and will be available on iOS, Android, and on a website.
  • A.M.E.: this software aims at analysing usages (movements, gaze data, clicks, timestamps, …) while passing neuropsychological tests such as TMT, and to automatically detect cognitive and memory disorders. It is compatible with Leap Motion and Tobii X1 Light Eye-Tracker.
  • DANCE: DANCE analyses the attributes of the items in users’ recent history and monitors the relative diversity brought by their consultations over time.
  • DANCE Visualisator: this is a Java software that allows researchers to dynamically visualize results from the DANCE model (see above).
  • Precog: this software has been designed to verify the existence of a link between memory and gaze data. On one hand, we are starting a collaboration with the Nancy University Hospital to study memory troubles among elderly persons, with the goal of automatically diagnosing memory issues based on fixation points, saccades and scanpaths. On the other hand, we are working on predictive models to provide recommendations of educational resources in Intelligent Tutoring Systems, according to what the user looked at and what the system assumes to be memorized. Concretely, Precog allows users to play to the well-known game called “Concentration” (also known as Memory, Pelmanism, Shinkei-suijaku, or Pexeso). In the meantime, the system collects gaze data such as fixation points and durations. Then, it uses these pieces of data to predict which items will be memorized according to primacy and recency effects. Our machine learning algorithm can still be improved, but first results are encouraging. Our application has been developed in C# so as to be compatible with a Tobii X1 Light eye-tracker and Tobii SDK. This prototype has been presented to more than 10,000 persons during the Renaissance Nancy 2013 exhibit. This software is available on demand.
  • StreetViewer: this software has been developed in C# for the need of the Renaissance Nancy 2013 exhibit. It has been designed to study and illustrate the added value of gesture-based software in certain contexts. StreetViewer allows users to use the Google service called StreetView without keyboard or mouse. A set of gestures have been defined and interpreted as actions by the software. It helped us to analyse users’ behaviours and understanding of such a system. We plan to use this software within a research project around well-being and aging process. It is also available on demand.
  • Commun-!T: this software, developped in PHP and Flex in 2012 is able to draw communities of users under the form of hyperbolic graphs. The input data are information about users and items. These data comes from various corpuses used and/or generated by KIWI algorithms. It is then able to display the links between users according to their preference similarities, their social relationship, or the level of trust they have in each others. It is also able to display the list of recommandations coming from and computed for each user.
  • FRAC+ Software: FRAC+ is a software developed in JAVA which fits with client/server architectures. Its goal is to provide a personalizing service within enterprise portals and e-commerce applications. The client part includes a module for user modeling and a recommender engine. The server part contains a clustering collaborative filtering algorithm allowing the system to build virtual communities of interests. This enables to acquire experience from similar population and to bypass the problems of missing data in individual preference models, thus improving the recommendation computations on the client side. This software has been successfully integrated in real industrial contexts as, for example: the Casablanca website broadcasting service of the company SES ASTRA (within the framework of the ESA Sat’n’Surf project), the intranet portal of the technological foresight department of Crédit Agricole S.A. (Paris, France), etc.
