The DiamondTouch table is a multi-touch, interactive PC interface product from Circle Twelve Inc. It is a human interface device that has the capability of allowing multiple people to interact simultaneously while identifying which person is touching where.〔Sandhana, L., ("Interactive display system knows users by touch" ), New Scientist, 25 May 2006〕 The technology was originally developed at Mitsubishi Electric Research Laboratories (MERL) in 2001〔 〕 and later licensed to Circle Twelve Inc in 2008.〔(Circle Twelve press release ) BusinessWire, 12 June 2008〕 The DiamondTouch table is used to facilitate face-to-face collaboration, brainstorming, and decision-making, and users include construction management company Parsons Brinckerhoff,〔Sharma, R., ("Multi touch computing change the next generation of computer" ) gyandotcom worldpress, 13 July 2008〕 the Methodist Hospital,〔Simon, S., ("Plato's Cave" ), KIAH-TV 39 Interactive, 16 September 2009〕 and the US National Geospatial-Intelligence Agency (NGA).〔Jay, E. F., ("Touch-Table Collaboration" ), Geospatial Intelligence Forum, 2007 Volume 5 Issue 4.〕 ==Overview== The DiamondTouch table is a front-projected interactive display that allows up to four users to sit face to face and work together on the same screen.〔Kageyama, Y., (Touch of the Future ), Associated Press, 5 June 2006〕 The DiamondTouch hardware enables a class of software known as "single-display groupware"〔 〕 where collaborative work is supported by computer interfaces that allow participants to be physically close. While product literature〔(DiamondTouch Product Flier ).〕 mentions consumer uses such as gaming,〔Hog, H., ("GDC 09: Diamond Touch: A multi-user touch tabletop" ), Destructoid, 27 March 2009.〕 customers of the DiamondTouch are using it for business and office applications.〔Kalinski, A., (Touched by a Multi-Touch World ), GeoSpatial Solutions, 10 March 2009.〕 The principal feature that distinguishes the DiamondTouch table from other multi-touch interfaces, such as the Apple iPhone, HP TouchSmart, Microsoft Surface or do-it-yourself systems inspired by the work of Jeff Han, is that the DiamondTouch table can identify who is touching where.〔Sandhana, L., (Interactive display system knows users by touch ), New Scientist, 25 May 2006〕 DiamondTouch achieves this feature through capacitive coupling between a transmitter array located in the touch surface and separate receivers located in the chair of each user.〔Anthes, G., (Give your computer the finger: Touch-screen tech comes of age ), ComputerWorld, 1 February 2008〕 The physical set-up of the system consists of the DiamondTouch device connected to a PC via USB cable, and a video projector suspended above the table and aimed down onto the touch surface. Cables connect chairs or receivers to the DiamondTouch unit. The current products have four receivers, thereby supporting one to four users.〔 A software development kit (SDK) allows developers to build custom software applications using standard programming languages including C, C++, Java, ActiveX (for C#, DHTML, VB.NET) and Adobe Flash. A mouse emulator enables operation of common software applications using multi-touch gestures for mouse functions (left button, middle button, right button and scroll wheel). A multi-user annotation software tool allows users to make mark-ups, selecting pen types from a pallet. In September 2008, Circle Twelve introduced a software extension for the geospatial information systems (GIS) software ArcView from ESRI.〔(Circle Twelve press release ), BusinessWire, 2 September 2008.〕 The software extension allows multi-user and multi-touch interactions in ArcView when used in conjunction with the DiamondTouch table.〔 抄文引用元・出典: フリー百科事典『 ウィキペディア(Wikipedia)』 ■ウィキペディアで「DiamondTouch」の詳細全文を読む スポンサード リンク
