In this paper, we present a new application framework aimed to support distributed synchronous collaboration using multi-touch interaction. The framework supports 2D and 3D virtual workspaces that enable two or more users to collaboratively or cooperatively manipulate shared objects with multi-touch interfaces. We present two applications developed with the aim to explore 2d/3d immersive collab...

The current work examines the phenomenon of Virtual Interpersonal Touch (VIT), people touching one another via force-feedback haptic devices. As collaborative virtual environments become utilized more effectively, it is only natural that interactants will have the ability to touch one another. In the current work, we used relatively basic devices to begin to explore the expression of emotion th...

Tabletop environments are ideal for collaborative activities that involve moving and arranging objects. However, manipulating 3D virtual objects through the 2D interface is challenging because users’ 2D actions must be translated into 3D actions. We explore the use of touch and tangibles to aid collaboration and 3D object manipulation. Our user study shows that using touch and tangible interact...

UNLABELLED PURPSOE: To investigate the diagnostic value of quantitative analysis of a tissue diffusion and virtual touch tissue imaging quantification (VTIQ) technique with acoustic radiation force impulse (ARFI) elastography for assessing enlarged cervical lymph nodes. MATERIALS AND METHODS Fifty-six enlarged cervical lymph nodes confirmed by pathologic diagnoses were covered in the study. A...

This paper presents a methodology for mapping a web page onto a 3D virtual reality environment enriched with haptic feedback and an application that has been developed according to the proposed methodology and gives blind people the opportunity to navigate through the internet by touch. According to the proposed haptic navigation in the world wide web, haptic and virtual modalities are combined...

In this paper, we present Virtual Touch, a toolkit that allows the development of educational activities through a mixed reality environment such that, using various tangible elements, the interconnection of a virtual world with the real world is enabled. The main goal of Virtual Touch is to facilitate the installation, configuration and programming of different types of technologies, abstracti...

CONTEXT Acoustic radiation force impulse imaging is an emerging imaging modality. The study of the pancreas is a new and promising application of ultrasound acoustic radiation force impulse imaging. CASE REPORT We present the first case of pancreatic serous cystadenoma which mimics a solid neoplasm at conventional imaging (US and CT), correctly diagnosed as cystic at ultrasound acoustic radia...

The Sound Flinger is an interactive sound spatialization instrument that allows users to touch and move sound. Users record audio loops from an mp3 player or other external source. By manipulating four motorized faders, users can control the locations of two virtual “sound objects” around a circle corresponding to the perimeter of a quadraphonic sound field. Physical models that simulate a spri...
