Coordinating team's work in a 3D Collaborative Virtual Environments is a real challenge. The communication constraints in such environments reduces the understanding between the partner's and thus complicates the team's coordintation. In order to facilitate the coordination, this paper proposes a hap tic tool for the designation of targets. This tool was experimented in a context of collaborative...
Previous studies about kinesthetic expressions of emotions are mainly based on acted expressions of affective states, which might be quite different from spontaneous expressions. In a previous study, we proposed a task to collect haptic expressions of a spontaneous stress. In this paper, we explore the effectiveness of this task to induce a spontaneous stress in two ways: a subjective feedback, and...
The use of virtual avatars, through facial or gestural expressions, is considered to be a main support for affective communication. Currently, different works have studied the potential of a kinesthetic channel for conveying such information. However, they still have not investigated the complementarity between visual and kinesthetic feedback to effectively convey emotion. This paper studies the relation...
In mixed reality, real objects can be used to interact with virtual objects. However, unlike in the real world, real objects do not encounter any opposite reaction force when pushing against virtual objects. The lack of reaction force during manipulation prevents users from perceiving the mass of virtual objects. Although this could be addressed by equipping real objects with force-feedback devices,...
Haptic devices are dedicated to render virtual tactile stimulation. A limitation of these devices is the intrusiveness of their mechanical structures, i.e. the user need to hold or wear the device to interact with the environment. Here, we propose a concept of new tactile device named HAIR. The device is composed of a computer vision system, a mechatronic device and air jets that stimulate the skin...
Collaborative Virtual Environments provide new working methods to associate several users on the same problem through different space and time configurations (synchronous/ asynchronous, distant/colocated). This new approach enables the simultaneous management of complex environments with several constraints for a more robust and efficient process. Previous studies investigate various features of synchronous...
The remote designation of targets in 3D complex environments, such as molecular structure, is a critical function since it is involved in numerous collaborative tasks. In fact, constrains such as depth perception and visual overload make the communication between partners very difficult and limit the understanding of the partners actions. This paper proposes a solution for the remote designation of...
Collaborative virtual environments introduce new working methods allowing for the association of several experts in the same problem-solving process. These new platforms have the potential to improve the processing of complex environments with large amounts of data and require different skills. This paper proposes the study of a synchronous and colocated approach for molecular design tasks. More precisely,...
Affective computing is among emerging fields for the design of new Human-Computer Interfaces. The facial expression was considered as the main way to communicate emotions. However, this approach presents some limitations for the recognition of complex emotions. Recent researches highlight new approaches to communicate effectively some emotions. The use of haptic feedback seems to be a promising solution...
Existing audio-haptic coupling strategies mainly enable the display of information with complementary features. For example, the rendering of spatial and local features of targets in 3D space. This paper presents the design of haptic stimuli for a new audio-haptic coupling strategy that utilizes the concurrent use of the two modal channels. This coupling strategy should assist in the intermodal comparison...
