A hybrid computing environment is described that uses small computing devices, such as PDAs (Personal Data Assistants), and a "computerized table". 3D sensors are installed in the environment and also attached to the user's PDA, so that the PDA can act as a flexible interaction device for the computerized table. The user can transfer data between the PDA… (More)
This paper describes a system that allows users who obtain " wearable ID key " to personalize dynamically ubiquitous computers by simply touching them. We call the concept of providing personalized service by touch " Active Personalization ". For active personalization, users only have to wear a digital key and do not have to carry around other computers.… (More)
This TechNote reports on our initial results of realizing a computer augmented wall called the Holo Wd. Using an infrared camera located behind the wall, this system allows a user to interact with this computerized wall using fingers, hands, their body, or even a physical object such as a document folder. INTRODUCTION .
This paper reports on our initial results of realizing a computer augmented wall called the HoloWall and HoloTable. Using an infrared camera located behind the wall, this system allows a user to interact with this computerized wall using fingers, hands, their body, or even a physical object such as a document folder.
is an interactive wall system that allows visitors to interact with digital information displayed on the wall surface without using any special pointing devices. The combination of infrared cameras and infrared lights installed behind the wall enables recognition of human bodies, hands, or any other physical objects that are close enough to the wall… (More)
Informal communication in a community is as important as formal meetings. We propose to support on-line informal communication by a visual communication tool, named <i>ChatScape.</i> A message on ChatScape is made of short text and still images. Short text messages are suitable for informal communication, and snapshots of users adds presence and hints of… (More)
The title compound, (C7H10N)2(H3O)2[Fe(CN)6] or (Etpy)2(H3O)2[Fe(CN)6] (Etpy+ is 1-ethyl-pyridinium), crystallizes in the space group Pnnm. The FeII atom of the [Fe(CN)6]4- anion lies on a site with site symmetry ..2/m, and has an octa-hedral coordination sphere defined by six cyanido ligands. Both the Etpy+ and the oxonium cations are located on a mirror… (More)
The methyl viologen dication, used under the name Paraquat as an agricultural reagent, is a well-known electron-acceptor species that can participate in charge-transfer (CT) interactions. The determination of the crystal structure of this species is important for accessing the CT interaction and CT-based properties. The title hydrated salt,… (More)
