Tabletop systems provide a platform for developing novel interaction systems, including tangible user interfaces (TUIs). This paper presents a study of the effects of a tabletop system with tangible user interfaces on designers' spatial cognition and design communication in collaborative design. In devising an experiment that can highlight the impact on spatial cognition while using TUIs, we compared designers using a tangible user interface (TUI) on a tabletop system to designers using a graphical user interface (GUI) on a typical desktop computer with mouse and keyboard. The designers were given a configuration design task in which they manipulated 3D objects to meet design specifications. Our preliminary findings are that designers using the tabletop system with TUIs reasoned about spatial relationships among 3D objects and discovered unexpected spatial relationships, while the designers using the traditional keyboard and mouse interfaces reasoned about individual 3D objects.

In this paper, we propose "pHotOluck" (a word coined by mixing "potluck" and "photo"), which is a novel tableware system for vitalizing mealtime communication by projecting photos taken by people who have a meal together onto special dishes. We conducted several experiments to investigate people's behaviors and communications, comparing pHotOluck with an ordinary photo viewing system that displays photos on a normal LCD PC display and with printed photos. The results of the experiments showed that pHotOluck could vitalize mealtime communications and offered everyone on equal chance to initiate communication although, compared to a normal photo viewing system and printed photos, pHotOluck is not so good as a photoviewer.

This paper presents a new type of tabletop interface on Lumisight table. Putting physical objects on a tabletop display is one of the typical methods for intuitive tangible input. To date, various interactive systems that can identify and track the tabletop objects by using a camera, have been proposed. However, in these systems, the existence of objects with special devices or markers can disturb users' natural interaction by hiding displayed information. To solve this problem, the authors propose a transparent tabletop interface that is transparent from users but visible from a camera installed inside the system. This paper describes our research motivation, design and implementation of this interface, and examples of interaction.

We present an effective corollary from our works in pen gesture technologies, originally intended for conventional digital screen environments, that gives significant influence when expanded into the domain of tabletop displays. By virtue of incorporating angular and velocity type "trace features" for pen gesture cognition into current classical linear classifiers, we are able to place a greater emphasis not on the similarity of the "visual representation" of the gestures, but rather, on determining exactly from which corners of the table the gestures were conceived. In other words, we can find out which one of the four users around the table is interfacing with the tabletop display at any particular time, and do this without the need for additional sensing paraphernalia. We illustrate this inception by discussing our treatment of "disoriented" pen gestures with our version of a 'manual' Monopoly board game for the tabletop.

A digital tabletop offers several advantages over other groupware form factors for collaborative applications. However, users of a tabletop system do not share a common perspective for the display of information: what is presented right side up to one participant is upside down for another. In this paper, we survey five different rotation and translation techniques for objects displayed on a direct touch digital tabletop display. We analyze their suitability for interactive tabletops in light of their respective input and output degrees of freedom, as well as the precision and completeness provided by each. We describe various tradeoffs that arise when considering which, when and where each of these techniques might be most useful.

We present the 3D Tractus: a simple and inexpensive system for interaction and exploration of three-dimensional (3D) data. The device is based on a traditional drawing board-like mechanical structure that can be easily moved up and down while its surface height is being tracked using a simple sensor. Users interact with a tablet or tablet PC that rests on the surface while simultaneously changing its height. The result is direct mapping of virtual and physical spaces allowing intuitive 3D interaction and data exploration. The 3D Tractus allows us to investigate novel 3D interaction techniques based on sketching and drawing as well as intuitive visual indicators and GUI layouts. The 3D Tractus' simple design concept can be easily adapted to other tabletop systems and the simple nature of the physical interaction allows the design of various exciting applications. We detail here the design and development of the 3D Tractus hardware and software as well as preliminary evaluation of a 3D drawing and sketching application realized using the new tabletop interface.

This paper presents the uPen, a laser pointer combined with a contact-pushed switch, three press buttons and a wireless communication module. This novel interaction device allows users to interact on large displays at a distance or directly on the surface with full-function of mouse. Onboard software enable the uPen system to identify different users and provide personalized services to them, such as associating users with corresponding privileges, giving access to each participant's private content (e.g., home pages, personal calendars). Additionally, with our two-step association method, the uPen system has the ability to distinguish strokes of different uPens working simultaneously and support multiuser simultaneous interaction. A prototype system has been implemented in our smart classroom (Shi et al., 2003). And user studies show the benefit of using it.

Advancements in mixed-reality (MR) systems have concentrated on the technology required for implementation, providing proof of concepts by means of technology tailored usage scenarios. These systems have been tested mainly on well contained tasks and applications specifically developed for these platforms. The potential impact of such techniques on actual work practices hence remains largely unexplored. We plan to investigate this practical relevance in more detail for industrial designers. Specific activities have been identified during a full ethnographic study conducted by means of cultural probes and workshops with representative participants. For one such activity, creating mood boards, a new MR interaction concept is to be designed and evaluated. We continue to use participatory design techniques to involve industrial designers at different stages of the design cycle.

Various communication systems in shared space technology have been proposed to support remote spatial collaborative works with physical objects. The authors have focused on sharing bodily interactions with physical objects between remote places, and have developed "Lazy Susan" communication systems. We have applied our unique communication system to support remote collaborative works and proved that our communication system is useful to change spatial and positional relation between a remote physical object and local self. Moreover, in order to exploit the feature of "Lazy Susan" communication system, we have proposed three modes; rotation, magnifying and personal mode, and implement visual tag interface as additional functions for a collaborative work. We discussed also uniqueness of our system in comparison to conventional communication systems and indicated its possibility.

Freehand gestural interaction with direct-touch computation surfaces has been the focus of significant research activity. While many interesting gestural interaction techniques have been proposed, their design has been mostly ad-hoc and has not been presented within a constructive design framework. In this paper, we develop and articulate a set of design principles for constructing - in a systematic and extensible manner - multi-hand gestures on touch surfaces that can sense multiple points and shapes, and can also accommodate conventional point-based input. To illustrate the generality of these design principles, a set of bimanual continuous gestures that embody these principles are developed and explored within a prototype tabletop publishing application. We carried out a user evaluation to assess the usability of these gestures and use the results and observations to suggest future design guidelines.
