Call For Participation The Second IEEE International Workshop on Horizontal Interactive Human-Computer System (Tabletop2007) Newport, Rhode Island, USA, October 10-12, 2007. Held in conjunction with ACM UIST 2007 http://www.ieeetabletop2007.org/ Supported by IEEE The use of the tabletop as an input/output device is an exciting and emerging research area. This cross-disciplinary domain brings together experts in projector based display systems, augmented reality, user interface technologies, multi-modal interaction, input and sensing technologies, CSCW, and information visualization. The purpose of the workshop is to bring together leading researchers in the field so that they can present and exchange current results of ongoing investigations. We encourage researchers and developers to present in the following areas as they relate to interactive tabletops: * Applications * Gesture-Based Interfaces * Multi-Modal Interfaces * Speech Interfaces * Tangible Interfaces * User Interface Technologies * Computer Supported Collaboration Systems * Middleware and Network Support * Augmented Reality * Social Protocols * HapticRendering * Information Visualization * Horizontal Display Hardware * Sensing and Input Technologies Paper Submission: We invite submissions of two kinds - regular research papers of up to 8 pages and short papers of up to 4 pages describing original research on investigations into horizontal oriented user interface based (tabletop) systems. Each paper must be submitted as a single PDF file in IEEE Computer Science Press format (described at ftp://pubftp.computer.org/press/outgoing/proceedings/instruct.pdf). Each paper will be peer reviewed by no less than three experts in the field. Accepted research papers will be included in the IEEE proceedings and presented in the paper sessions. Submission details will be available at: http://www.ieeetabletop2007.org/ Important Dates: June 8th, 2007: Paper titles and abstracts due June 15th, 2007: Paper submissions due July 12th, 2007: Notification of acceptance sent to authors October 10-12, 2007: Tabletop2007 workshop, Newport, RI.
