Touch-sensitive devices become more and more common all-around. Many people use touch interaction, especially on small devices like iPhone or other mobile phones and handhelds. But do they really understand the different gestures, know which gesture is the correct one for the intended action and do they know how to transfer the gestures to bigger devices and surfaces? This paper reports about u...

Adaptation to temporal asynchrony between senses (audiovisual and audiotactile) affects the subsequent simultaneity or temporal order judgment. Here, we investigated the effects of adaptation to temporal asynchrony between vision and touch. Participants experienced deformation of virtual objects with a fixed temporal lag between vision and touch. In subsequent trials, the visual and haptic stim...

Interactive surfaces form an integral component of intelligent environments. In the paper, we describe HapticArmrest, a simple tactile interface that communicates tactual surface characteristic and form of interactive elements on direct touch surfaces. Spatially separating manual touch input and active tactile output allows for the combination of various types of tactile actuators for versatile...

To investigate the diagnostic performance of combined use of conventional ultrasound (US) and elastography, including conventional strain elastography such as elasticity imaging (EI) and acoustic radiation force impulse (ARFI) elastography, and to evaluate their usefulness in recommending fine-needle aspiration (FNA).A total of 556 pathologically proven thyroid nodules were evaluated by US, EI,...

Recent developments in multi-touch technologies have exposed fertile ground for research in enriched human-robot interaction. Although the technologies have been used for virtual 3D applications, to the authors’ knowledge, ours is the first study to explore the use of a multi-touch table with a physical robot agent. This baseline study explores the control of a single agent with a multi-touch t...

OBJECTIVE The purpose of the present study was to explore the correlation between the contrast-enhanced ultrasound (CEUS) and acoustic radiation force impulse (ARFI) characteristics of breast cancers and the expression of human epidermal growth factor receptor 2 (HER-2). METHODS HER-2 expression levels in the tumor masses of 167 clearly diagnosed cases of breast cancer were measured and analy...

Pain relief by touch has been studied for decades in pain neuroscience. Human perceptual studies revealed analgesic effects of segmental tactile stimulation, as compared to extrasegmental touch. However, the spatial organisation of touch-pain interactions within a single human dermatome has not been investigated yet. In 2 experiments we tested whether, how, and where within a dermatome touch mo...

In this paper we present a study in which participants played a collaborative augmented reality game together with two virtual agents, visible in the same augmented reality space. During interaction one of the virtual agents touches the user on the arm, by means of a vibrotactile display. We investigated whether social touch by a virtual agent in a collaborative setting would positively influen...

The aim of this prospective study was to propose a new rating system using a risk model including conventional ultrasound (US) and acoustic radiation force impulse (ARFI) elastography for predicting central lymph node metastasis (LNM) in patients with papillary thyroid microcarcinoma (PTMC).A total of 252 patients with PTMCs were enrolled, who were preoperatively evaluated by US and ARFI elasto...
