Haptic virtual fixtures have a key role in telepresence systems to enhance spatial perception as well as to improve task efficiency. However, there are some difficulties in bringing real and virtual constraints together due to the extremely different characteristics of their representations. This paper proposes a unified virtual fixture model for the telepresence systems to combine the autonomously...
This paper introduces a unique type of mixed reality system based on passive-haptic feedback, which enables its user to manipulate real objects with bare hands while seeing its counterpart in the HMD with more information attached. The system provides users in MR systems with a more realistic sense of touch and costs less money comparing to the active force feedback devices. In this paper, accuracy...
In this paper, we propose a pseudo-gustatory display based on the cross-modal interactions that underlie the perception of flavor. Although several studies on visual, auditory, haptic, and olfactory displays have been conducted, gustatory displays have seldom been studied. This scarcity has been attributed to the fact that synthesizing arbitrary taste from basic tastants is difficult. On the other...
In this paper we describe a prototypical system for live musical performance in a virtual studio environment. The performer stands in front of the studio camera and interacts with an infrared-laser-based multi-touch device. The final TV image shows the performer interacting with a virtual screen which is augmented in front of herself. To overcome the problem of the performer not seeing this virtual...
We present an approach for visuo-haptic augmented reality, which is focused on object manipulation tasks. The interactive environment combines three-DOF haptic rendering and physics-based animation. A desktop haptic device with force feedback is driven by the user to interact with movable virtual objects that are superimposed upon a visual representation of the real workspace. Virtual objects coexist...
Haptic interfaces in Augmented Reality scenarios are an efficient way to enhance the interaction with a virtual world. We introduce a new system that involves both hands in virtual object experience. We render contemporary shape and weight of a virtual object, merged in a real world environment, using a commercial haptic interface and a new kind of finger-worn device. We test the system with an experimental...
A Digilog Book is an augmented reality (AR) based next generation publication supporting both sentimental analog emotions and immersive digital contents to improve a user's experience. This paper enhances the Digilog Book authoring tool, ARtalet. This is a tangible user interface based immersive AR authoring tool providing an intuitive non-programming based authoring methods using a 3D user interface...
Supermarkets are one of the most functionally challenging environments for visually impaired (VI) individuals. A modern supermarket has a median area of 4,529 square meters and stocks an average of 45,000 products. We will demonstrate ShopMobile II, a mobile shopping system for VI individuals. ShopMobile II is implemented on the Google Nexus One smartphone. We will demonstrate how haptic and audio...
In this paper, we present a Fitts' law-based formal evaluation process and the corresponding results for 3D object manipulation techniques based on a virtual hand metaphor in a tangible augmented reality (TAR) environment. Specifically, we extend the design parameters of the 1D scale Fitts' law to 3D scale and then refine an evaluation model in order to bring generality and ease of adaptation to various...
Visuo-haptic mixed reality consists of adding to a real scene the ability to see and touch virtual objects. It requires the use of see-through display technology for visually mixing real and virtual objects, and haptic devices for adding haptic interaction with the virtual objects. However, haptic devices tend to be bulky items that appear in the field of view of the user. In this work, we propose...
Visual delays are unavoidable in augmented reality setups and occur in different steps of the rendering pipeline. In the context of haptic interaction with virtual objects, it has been shown that delayed force feedback can alter the perception of object stiffness. We hypothesize that delays in augmented reality systems can have similar consequences. To test this, we carried out a user study to investigate...
This paper proposes a novel low-cost robotic telepresence approach to situation awareness, initially aimed for hazardous environments. The robot supports omnidirectional movement, wide field of vision, haptic feedback and binaural sound. It is controlled through an augmented virtuality environment with an intuitive position displacement scheme that supports physical mobility. The operator thereby...
This paper presents an architecture to support fast prototyping of augmented reality systems, based on virtual reality. The architecture defines simulation services separated from other aspects of the system. These services support incremental evolution of simulated prototypes into nonsimulated systems. Focus is also placed on user interaction,through the definition of an interaction architecture...
