Un dispositif d'interaction pour favoriser la discussion et l'engagement dans les musées

National audienceMuseums propose more and more digital devices to enrich the visits. However, these devices can take much of the visitor's attention and hinder the social dimension of the visit. We propose a device for groups. It provides a non-intrusive interaction with the aim to foster discussions between visitors. The device has been deployed and experimented in a fine art museum. We describe in this article the design of the device as well as the experiment and results. It allowed us to validate acceptability and usability of the device and shows a positive effect about engagement with the artworks and to a lower extent an effect on discussions between visitors.Les musées proposent de plus en plus de dispositifs numériques destinés à enrichir les visites.

Lateral Touch and Frictional Vibrations of Human Fingerprints

In this report, we experimentally show that human fingerprints play a significant role in the lateral touch vibratory mechanisms and that direction of movement results in differ-ent dynamic strains on the pulp. Sources that generate sound at the interface are first empiri-cally identified and a spherical model of the index finger is proposed to forecast the radiated fields. Then, haptic sounds are recorded using a miniature microphone placed in the near field. Results are compared with vibrometric measurements carried out in quite similar conditions to assess of the results relevance. Results show that fingerprints can?t be neglected in the tri-bologic interaction. Finally, this research provide a useful information for tactile displays de-signers and offers future investigations perspectives in many research fields linked with the haptic science

Guide de conception d'une technique de désignation 3D

National audienceNous présentons un tour d'horizon des techniques de désignation existantes en IHM, aussi bien en 2D qu'en 3D. Leur analyse nous a permis de proposer un guide de conception d'une technique de désignation 3D pour les développeurs d'environnements virtuels. Une illustration de cette méthode est proposée avec le pointage sémantique en 3D

Which interactions to foster the social dimension of museum visit?

International audienceCollaboration and social dimension are more and more recognised as a fundamental dimension of museum visits. In this article we review existing works to support social interactions between visitors and we present our proposals to foster group discussion during visits. This kind of support can provide a basis for the development of visitor communities around these social interactions

Does DOF Separation on Elastic Devices Improve User 3D Steering Task Performance

Abstract. We investigated the use of a new haptic device called the DigiHaptic in a 3D steering task. Unlike other devices intended to interact in 3D with one end-effector, the DigiHaptic has three levers that the user may handle simultaneously or not in elastic mode to rate control objects. We compared it to the SpaceMouse- another elastic device- to evaluate the influence that degrees of freedom (DOF) separation have in terms of accuracy (coordination and errors) and speed (time). The task consisted of steering paths that required the use of two or three DOF simultaneously. We found that users performed faster on the SpaceMouse but were less coordinated and accurate than on the DigiHaptic for the most complicated paths.

Elastic Force Feedback with a New Multi-finger haptic device: The DigiHaptic

Abstract. This article presents a classification of and comparison between isotonic, isometric and elastic devices. It then introduces the DigiHaptic, a new three degrees of freedom multi-finger force feedback device, and its place in the device classification is proposed. Two notable features of the DigiHaptic are the decoupling of the degrees of freedom and the correlation between fingers and objects movements. Finally two force feedback solutions using the DigiHaptic in elastic mode are proposed for rate control in open and closed workspaces.
