Virtual reality (VR) technology enables the simulation of certain learning scenarios that would be risky or difficult to set up or repeatedly replicate in the actual world. This paper introduces a VR simulator created for this aim with the assistance of social educators. The purpose is to use VR to conduct learning exercises with teenagers with ID and assess the extent to which the abilities learned in VR can be transferred to the real world. This project focuses mainly on urban mobility with three types of exercise. A study was conducted with 18 students in five institutions for 7 months. Post-tests were also carried out after 1 month with 11 teenagers. In the end, four teenagers are completely autonomous in their travels: two travel on foot and two travel by public transport. Regarding the impact analysis, t...

In order to avoid problems related to computer vision (sensitivity to lighting changes, reliance on camera position, etc.), the proposed approach doesn't make use of optical techniques. Furthermore, in order to make human communication and control smooth, and avoid other environmental artifacts, the used information is non-verbal. The head's ...

As a consequence, the problem of finding the right information, at the right time, in a short period of time, becomes more and more crucial. Several technologies such as semantic web data mining and interactive visualizations are nowadays available to address these specific issues. However they ...

It is important to be able to record a large amount of data. On another hand, it is useful to be able to find a specific data among all the data recorded. The more data we have the higher is the difficulty to visualize them. The solution that is presented here below is based on a particular visualization of content based on filter. A Knowledge Management System provides the storage part. The storage is based on an ontology specifically designed for travels. The ontology provides a data structure with the creation of concepts. This structure allows at the same time the sorting of data and a clear visualization. The visualization is dynamic, it depends on the ontology relationship established.

Nowadays, effective retrieval and usage of multimedia resources have to deal with the issues of creating efficient indexes, developing retrieval tools and improving user oriented visualization interfaces. To that end we put forward an integrated framework named CALIMERA. The framework is based on a High-level modEL for cOnference (HELO) and ...

Gesture segmentation has two main goals: first, detecting when a gesture begins and ends, second, understanding whether a gesture is meant to be meaningful for the machine or is a non-command gesture (such as gesticulation). This work proposes a novel hands-free, always-available approach for the gesture segmentation and recognition in which the user can communicate directly ...

In particular, the system recognizes the following five activities: "walking", "running", "cycling", "sitting" and "standing". We conducted a study in order to select the opportune muscles and sensors placement. Furthermore, we evaluated the system conducting two analyses: impersonal and subjective. The impersonal analysis evaluated the system behavior when it was trained on several users' data; on the opposite, the subjective analysis evaluated the system when it was specialized on a single subject data. In the impersonal analysis, the accuracy rate was 96.8% for the 10-fold cross-validation and 91.8% for the leave one subject out. The system accuracy rate for the subjective analysis was 99.4%.

In particular the Electroencephalogram signals (EEG) have been used to provide new ways for communication and control. However, such kind of technology presents some important drawbacks such as the price and the difficulty to prepare the system without an expert's support. This work intends to build a user-friendly, self-paced Brain-Computer Interface ( ...

Moreover, the advent of the web as a main distribution channel imposes to manage heterogeneous types of data and to deal with the issue of finding efficiently the pertinent information becomes more and more important. Several approaches such as semantic annotation, data mining, virtual and interactive visualizations are nowadays available to ...

This approach is based on a wearable paradigm of interaction, in which the sensors are placed on the user's arm. The wearable system communicates with the infotainment system of our prototype through Bluetooth. We designed the gesture vocabulary in order to facilitate the driver interaction with the infotainment system while holding the steering wheel with both hands. We tested our approach with eight users showing the possibility to recognize four microgestures with an average accuracy of 94.55%.
