We present a new affective interaction technique, called CheekTouch, by combining tactile feedback, delivered through the cheek, and multi-finger input, while speaking on the mobile phone. We designed a prototype by using a multi-touch mobile device and a 4x3 vibrotactile display device. We identified six affective touch behaviors (pinching, stroking,(More)
A novel PCR restriction analysis method using the RNA polymerase beta-subunit- coding gene (rpoB) was employed to both detect and identify Helicobacter pylori in biopsy specimens and culture isolates. The rpoB DNAs (458 bp) were specifically amplified by PCR with the Helicobacter-specific primers (HF and HR). Based on the determined rpoB sequences of the(More)
A geographic map is an important browsing tool for multimedia data that can include personal photos, but geographically correct maps are not always easy to use for that purpose due to the frequent zooming and panning, as well as the existence of extraneous information. This paper proposes a new user-interface concept for geo-tagged personal multimedia(More)
Geographical differences in the genetic diversity of Helicobacter pylori isolates were examined by analyzing rpoB sequences. An extremely high level of allelic diversity among H. pylori strains was found. The rpoB sequences of Asian and non-Asian (North and South American, European, and South African) strains were found to differ. An amino acid polymorphism(More)
This paper presents MixPlore, a framework for a cocktail-based live media performance. It aims to maximize the pleasure of mixology, presenting the cocktail as a plentiful art medium where people can fully enjoy new synesthetic contents by the integration of bartending and musical creation. For this, we fabricated Tangible User Interfaces (TUIs): tin,(More)
We created entertainment systems called "Hanmadang". The goal of the Hanmadang project is to allow players to experience massive face-to-face interaction. To reduce entry barriers of participation, it enables players to use their own mobile phone as an input interface by using an audio response system. Two games "Youngcha!" and "Hankanoid" are developed as(More)
