This paper presents the results of an exploratory comparative study in which we investigated the relationship between interface style and school-aged children's enjoyment and engagement while doing puzzles. Pairs of participants played with a jigsaw puzzle that was implemented using three different interface styles: physical (traditional), graphical and(More)
Multi-touch interaction with computationally enhanced surfaces has received considerable recent attention. Approaches to the implementation of multi-touch interaction such as Frustrated Total Internal Reflection (FTIR) and Diffused Illumination (DI) have allowed for the low cost development of such surfaces, leading to a number of technology and application(More)
The sense of touch has been traditionally neglected in aesthetics. However, interaction design seems to always require some level of tactility or body activity for the experience. In this paper, I first give an overview of the historical arguments against a tactile aesthetics and offer reasons why these reasons are no longer valid. In the second section, I(More)
OBJECTIVES Sedation is required to perform endoscopic retrograde cholangiopancreatography (ERCP) and endoscopic ultrasound (EUS) given the duration and complexity of these advanced procedures. Sedation options include anesthetist-directed sedation (ADS) vs. gastroenterologist-directed sedation (GDS). Although ADS has been shown to shorten induction and(More)
Multi-touch interaction with computationally enhanced surfaces has received considerable attention in recent years. Hardware implementations of multi-touch interaction such as Frustrated Total Internal Reflection (FTIR) and Diffused Illumination (DI) have allowed for the low cost development of surfaces. Although many of these technologies and associated(More)
In this paper, we describe our first prototype in implementing a robust and low-cost multi-touch and tangible system using a High Definition LCD monitor. Since our prototype utilizes an LCD, we discuss and compare the advantages that HD LCD monitors provide over projectors. Secondly, we give an overview of the sensing data the system can detect, and what(More)
We present an overview of <i>Keep in Touch</i>, a networked fabric touchscreen designed to support and maintain intimacy for couples in long distance relationships. To achieve this, a novel sensorial interface was created by combining the visual and tactile senses together. Each partner is presented with a blurred digital projection of their lover. When(More)
The EventTable technique is a tangible object tracking technique implemented on a camera vision based tabletop platform. The technique supports an event-driven -- rather than object centric -- tracking technique. Fiducial markers are distributed between objects. When objects are brought into a proximal or connected relationship, a whole marker is formed and(More)
OBJECTIVES Acute cholangitis mandates resuscitation, antibiotic therapy, and biliary decompression. Our aim was to define the optimal timing of endoscopic retrograde cholangiopancreatography (ERCP) for patients with acute cholangitis. METHODS Clinical data on all cases of cholangitis managed by ERCP were prospectively collected from September 2010 to July(More)
