In this paper we study the memorization of user created gestures for 3DUI. Wide public applications mostly use standardized gestures for interactions with simple contents. This work is motivated by two application cases for which a standardized approach is not possible and thus user specific or dedicated interfaces are needed. The first one is applications for people with limited sensory-motor abilities...
This paper presents the design of “Virtual Arrow”, a 3D simulator for traditional archery. Traditional archers aim without a target figure. Good shooting results require an excellent body-eye coordination that allows the user to perform identical movements during each shot. The fascination of this sport is mainly based on a positive user experience when drawing the bow, focusing the target, releasing...
Volume data analysis often involves finding structures inside the volume. Segmentation is the standard method, but it is quite time-consuming. Alternate approaches remove context, assume prior definition of ROI or segments, or distort part of the volume. We propose a new bimanual 3D interaction technique, called Volume Cracker (VC), which allows the user to crack open a volume like a book to analyze...
Haptic feedback is important to improve the operability of virtual objects. However, AR systems with haptic feedback are still not many. Moreover, users cannot perform tasks that need large workspaces in those systems because of physical constraints from haptic feedback devices. In this paper, we combined a wearable haptic device and a marker-less AR technology to develop an AR system in which users...
