ABSTRACT
This paper describes a novel 3D carousel intended for virtual showcasing.
The carousel is based on a 3D ring menu which is rendered
on a 3D display. The user interaction with the carousel is achieved
by tracking the user’s gestures while the behavior of the carousel
is modified through physically-based pseudo-haptic effects. The
pseudo-haptic effect is based on modifying the friction coefficient
taking into account the relevance of the objects displayed in the
carousel. In addition a magnetic effect is introduced in order to
attract to the active item of the carousel. The results from a first
user study are globally encouraging and provide insights about the
potential of our 3D pseudo-haptic carousel for virtual showcasing.

1 INTRODUCTION
In this paper we focus on the use of low-cost VR technologies to
showcase virtual products. Indeed, many application fields aim at
presenting content using ground-breaking showcase. From professional
exhibitions, to virtual shopping, or art installation in a museum,
interactive kiosks can greatly improve the experience of a
large public.
Our goal is thus the development of an interactive kiosk for the
showcasing of virtual products. The requirements of such a widespread
application include a minimum training process, a natural
and intuitive user interface. Among the large number of existing
3D graphical user interfaces (see survey from Dachselt and H¨ubner
[3]), we chose ring menus and 3D carousels. These interfaces are

already well-known and are widely used to navigate in multimedia
catalogs (web, music, image, video, 3D models). Furthermore, in
order to increase the immersion of the user without the need of expensive
equipment, our choice was the use of marker-less tracking
and a passive stereoscopic display. The consistency between 3D
gestural interaction and 3D visual content is expected to improve
usability as the user will interact directly with 3D content using
his or her own body. The user will only require to wear polarized
glasses.
Therefore, the main contributions of this work are : (1) the design
of a control law for virtual carousels based on users hand gestures,
(2) the extension of the proposed control law to introduce a
pseudo-haptic feedback meant to repulse/attract the user to some
specific items, and (3) a user evaluation of the proposed approach.
In the remainder of the paper we first describe some related work
in 3D graphical user interfaces and pseudo-haptics. Second, we
detail the different components of our approach focusing on our
interaction metaphors and new pseudo-haptic effect. Finally, we
present the results of a user study and end up with some concluding
remarks.
