This paper introduces TurTan, a tangible programming language for creative exploration inspired by Logo, which uses a tabletop interface with tangible objects. The aim of this project is to design a toy language for programming entertainment and creative purposes. Along this paper we also discuss some interesting technical issues we have found during its implementation such as tangible linking and angle mapping.

Most tabletop research presents findings from lab-based user studies, focusing on specific interaction techniques. This means we still know little about how these new interfaces perform in real life settings and how users appropriate them. This paper presents findings from a field study of an existing interactive table in a museum of natural history. Visitors were found to employ a wide variety of gestures for interacting; different interface elements invited different types of gesture. The analysis highlights challenges and design conflicts in the design of tabletop interfaces for public settings, such as latency times and side-effects of dasiaframe-lesspsila content, which had some users struggling to learn how to interact. While the majority of visitors engaged at least briefly with the table, which enabled browsing question-answer text about animal species, talk amongst visitors dealt mainly with how to interact and evoked few comments, indicating shallow engagement with content.

In order to increase the ways that users can intuitively interact with a tabletop display, we developed UlteriorScape. This system integrates two major functions of its predecessors. As with Tablescape Plus, UlteriorScape uses tabletop objects as both projection screens and input interfaces. As with the Lumisight Table, the tabletop is physically single, but visually multiple with a view-dependent display, which can show different images to each user around the table. We developed several applications that demonstrate the advantages of UlteriorScape. In one, a single user can hold a simple screen-object over the tabletop and see additional images projected onto its surface. Those images change interactively based on the position of the object, which is tracked by ID. In another application, multiple users can simultaneously work with a single mountain-shaped object that displays separate images on each side. In this paper, we describe the system design of UlteriorScape and its applications.

In this paper we examine tilted tabletops as workspaces for computer-supported group collaboration. The configuration of a tilted tabletop is considered to be in between a fully horizontal tabletop and a vertical whiteboard. We describe related work, and provide an overview of the advantages and disadvantages of such a configuration. Furthermore, we present the results of a user study about tilted tabletops. We captured the tilt angle preference of 78 participants using mock-ups of the basic workspace elements. The study was conducted after they experienced a combined distributed and co-located collaboration. The results of the study reveal that the majority of the participants prefer a tilted workspace rather than a fully horizontal one for interaction. We discuss the implications of these results for the design of tabletop-based collaborative environments.

This paper introduces the Tabletop AgilePlanner, an advanced prototype that applies tabletop technology to support collocated and distributed agile planning meetings. By introducing the novel tabletop-based project planning tool, this paper contributes to the agile and tabletop research in threefold: First, it provides real world experience of using a digital tabletop to solve practical problems, not just a demonstration of tabletop capabilities. Second, it shows a multipart usability evaluation that exposes the benefits and limitations of using digital tabletop to develop project planning applications. Third, it expresses some trade-offs that impact the design of the Tabletop AgilePlanner. Since the design experience and trade-offs come from a real practice, this paper provides insights into the construction of real world tabletop applications.

Knowledge workers often undertake tasks that involve a variety of information artifacts, including both paper and digital documents. In this paper, we first summarize findings from a study that illustrate some of the challenges of managing tasks that include both paper and digital content. We then introduce DocuDesk, a prototype interactive desk that demonstrates interaction techniques for establishing many-to-many linkages among paper and digital documents which can be used to quickly ldquorehydraterdquo task state.

Negotiation and coordination of activities involving a number of people can be a difficult and time-consuming process, even when all participants are collocated. We propose the use of spatial proximity regions around mobile devices on a table to significantly reduce the effort of proposing and exploring content within a group of collocated people. In order to determine the location of devices on ordinary tables, we developed a tracking mechanism for a camera-projector system that uses dynamic visual markers displayed on the screen of a device. We evaluated our spatial proximity region based approach using a photo-sharing application for people sat around a table. The tabletop provides a frame of reference in which the spatial arrangement of devices signals the coordination state to the users. The results from the study indicate that the proposed approach facilitates coordination in several ways, for example, by allowing for simultaneous user activity and by reducing the effort required to achieve a common goal. Our approach reduced the task completion time by 43% and was rated as superior in comparison to other established techniques.

An advantage of physical interfaces over graphical widgets is that they bring controls closer to hand. VoodooSketch is a system that supports dynamic customisation of tabletop interfaces with physical controls that users can arrange on palettes. The system employs pen and paper techniques to achieve two novel capabilities: first, users are able to sketch controls that are immediately operational for pen interaction; second, users can label the controls with a handwritten name that identifies their function and binds the control to an application. This paper presents the results of an empirical evaluation of the VoodooSketch interface customisation techniques. The main findings of the study are: that users are able to easily create sketched controls; that they can use them as effectively as traditional input devices; that handwritten labelling is more efficient for control mapping than conventional screen-based methods; and that the sketched controls improve user performance and reduce error rates.

This paper discusses some general results from an in-situ study of the use of a tabletop system for card playing that differs in several ways from most tabletop systems: 1. It was designed primarily for use by senior citizens with little or no computer experience. 2. It is a single-user system, though social interaction with nearby persons during its use is typical. 3. It includes a simple conversational agent (representing the gamepsilas other player). 4. It is used in a setting (a senior citizenspsila center) in which the users also play cards in the traditional ways. A total of 42 regular visitors of the center participated over a 4-week period. From our observations and results, we draw several conclusions that should apply to other tabletop systems that share one or more of the characteristics just listed.

To date, digital tabletop research has predominantly focused on resolving fundamental software and hardware challenges introduced by this new interactive platform. Understanding not only what technical functionality a digital tabletop can provide, but also how appropriate that functionality is for different usage contexts is crucial in designing tables intended for use outside of the research lab. In this paper, we propose five contextual factors to consider in the tabletop design process - social and cultural, activity, temporal, ecological, and motivational - and discuss how these factors influence the design of three main aspects of tabletop systems: software interface, physical form, and connectedness. This work provides a means for tabletop designers to understand the factors that impact the applicability of existing and future design approaches for a given context of use.
