La minéralité perçue dans le vin
2015
Article technique.; National audience; Beaucoup des aspects les plus fondamentaux et passionnants du vin demeurent conceptuellement insaisissables. Lorsque nous y sommes confrontés d’un point de vue sensoriel, nous pouvons avoir l’impression de bien connaître les attributs les plus abstraits du vin comme la qualité, la complexité et la minéralité, mais d’un point de vue scientifique nous savons très peu de chose sur ce que précisément ces termes signifient à la fois pour les professionnels et les consommateurs de vin. Par exemple, malgré l’intérêt actuel de la filière et des producteurs pour la perception de la minéralité dans le vin et l’utilisation de plus en plus fréquente de ce terme pa…
Constructing co-presence through shared VR gameplay
2021
This study analyzes how participants playing VR games construct co-presence and shared gameplay. The analysis focuses on instances of play where one person is wearing the VR equipment, and other participants are located nearby without the ability to directly interact with the game. We first show how the active player using the VR equipment draws on talk and embodied activity to signal their presence in the shared physical environment, while simultaneously conducting actions in the virtual space, and thus creates spaces for the other participants to take part in gameplay. Second, we describe how other participants draw on the contextual configurations of the moment in displaying co-presen…
To embody or not to embody: A sound design dilemma
2019
Designing with sound is about constructing appropriate sound representations of a concept, from the early ideas to the final product. A survey research on embodied sound sketching is presented, and the problems of early representation in sound design are discussed by analysing the questionnaire results of three workshops on vocal sketching.
Cooperative sound design: a protocol analysis
2016
Formal protocol analysis and linkographic representations are well-established approaches in design cognition studies, in the visual domain. We introduce the method and tools in the auditory domain, by analysing a case of collaborative sound design. We show how they can provide relevant qualitative and quantitative information about the efficiency of the creative process.
Measuring the Task Induced Oscillatory Brain Activity Using Tensor Decomposition
2019
The characterization of dynamic electrophysiological brain activity, which form and dissolve in order to support ongoing cognitive function, is one of the most important goals in neuroscience. Here, we introduce a method with tensor decomposition for measuring the task-induced oscillations in the human brain using electroencephalography (EEG). The time frequency representation of source-reconstructed singletrail EEG data constructed a third-order tensor with three factors of time ∗ trails, frequency and source points. We then used a non-negative Canonical Polyadic decomposition (NCPD) to identify the temporal, spectral and spatial changes in electrophysiological brain activity. We validate …

Effects of Positioning Aids on Understanding the Relationship Between a Mobile Map and the Environment
2013
Positioning technologies such as GPS enable mobile map applications to display a symbol representing an estimation of a user’s location on a mobile map, therefore acting as a positioning aid. Previous research on the cognitive processes involved in map reading suggests that map readers need at least two map–environment points (objects that are visualized on the map and perceived in the environment) for determining their location on a map. Hence, the positioning aid alone does not provide enough information for self-location. Using a field experiment, we assessed the effect of representing the user’s location on a map on the cognitive processes involved in self-location. The results show tha…
Changes in the flight paths of pigeons based on extended spatial landmarks: Poster
2021
The navigational behavior of birds is based on the spatial perception of the terrain over which they fly. Not only single reference points, but also continuous linear and areal objects can be visually perceived in flight and affect the flight path. In this work, we studied the features of the trajectories of pigeons during flights in order to identify the effect of discrete or continuous extended landmarks on spatial orientation. For this purpose we compared the GPS tracks of pigeons flying over weakly familiar terrain, and the visual features of this terrain, calculated on the basis of remote sensing data. Various cases of linear landmarks (alleys, rivers, roads) and boundaries between dif…
