With ageing of the population in the world, patients with Alzheimer's disease (AD) consequently increase. People suffering from this pathology show early modifications in their "activities of daily living". Those abilities modifications are part of the dementia diagnosis, but are often not reported by the patients or their families. Being able to c...
In the most common approach to corpus-based concatenative synthesis, the unit selection takes places as a content-based similarity match based on a weighted Euclidean distance between the audio descriptors of the database units, and the synthesis target. While the simplicity of this method explains the relative success of CBCS for interactive descr...
This paper shows methods for defining and rendering Sound Level of Detail (SLOD) for audiographic scenes using corpus-based granular synthesis. We introduce three levels of detail for sound (individual events, statistical texture, background din), to define a proximity profile around the listener. The smooth transition between the levels is assured...

In audio–graphic scenes, visual and audio modalities are synchronized in time and space, and their behaviour is determined by a common process. We present here a novel way of modeling audio–graphic content for interactive 3D scenes with the concept of sound processes and their activation through 2D or 3D profiles. Many 3D applications today support...
The invention concerns a method for creating a saliency map of an image. It comprises the steps of an image comprising the step of hierarchical decomposition of the image into frequential sub-bands, According to the invention, the method comprises the steps of - movement estimation between the current image (I(t)) and a preceding image (I(t-nT)) ca...
While bottom-up approaches have emerged as the standard, default approach to clustering for speaker diarization we have always found the top-down approach gives equivalent or superior performance. Our recent work shows that significant gains in performance can be obtained when cluster purification is applied to the output of topdown systems but tha...
In this paper we address the question of extending user experience in large scale tactile displays. Our contribution is a non task-oriented interaction technique based on modern dance for the creation of aesthetically pleasant large scale tactile interfaces. This approach is based on dance movement qualities applied to touch interaction allowing fo...
We present a strategy for the improvement of wireless sensor data transmission latency, implemented in two current projects involving gesture/control sound interaction. Our platform was designed to be capable of accepting accessories using a digital bus. The receiver features a IEEE 802.15.4 microcontroller associated to a TCP/IP stack integrated c...
(land)moves is an interactive installation: the user’s gestures control the multimedia processing with a total synergy between audio and video synthesis and treatment.
