Tabletops - Horizontal Interactive Displays

Tabletop displays are mostly used for casual applications that do not require intricate graphics or precise manipulation. Browsing photographs and maps are common applications. A higher resolution is required to support work involving detailed graphics and text. A display the size of a desk, with the resolution of a typical LCD monitor, will have around 14 megapixels. Tabletop displays are usually constructed from projectors, and the only way to achieve this size and resolution is to combine multiple projectors. We present techniques from multiprojector display walls and adapt them for tabletops. These high-resolution displays also require high-resolution input, and although touch is simple and natural, better accuracy can generally be achieved using a pen. We also review technologies for pen input on tabletops.

Abstract. In this paper, we present a new technology to track multiple active Tangible User Interfaces (TUI) on a projection table. We use a commercial high speed infrared tracking camera with modified firmware. With a special tracking method, we reach update rates of up to 250 Hz with low latencies. At this tracking rate, we are able to track the position, state and the orientation of more than 10 active TUIs on the table. For this, we use specified bit codes which are transmitted by the devices. We developed dedicated hardware (SyncUnit) and software to keep the devices and the high speed camera synchronized. The system of camera, SyncUnit, and devices is fully hardware controlled and delivers event coded tracking data for further usage in interactive applications.

“…From these relationships, the orientation and other functions can be derived. The developed input technology is explained in [24]. In order to realize the local teamwork as intuitive as possible, different devices were designed, which we will introduce in the following paragraphs.…”

The early stages of the product development process are the most important ones. Decisions made here affect the success of a new product. Due to the complexity of products, a multidisciplinary knowledge is required. In the globalized world the company's internal and external experts are spread all over the world. Time and cost pressure impedes teamwork with personal attendance. As a result, personal meetings are strictly limited and teamwork is often reduced to e-mail or phone communication, combined with shared document repositories. Especially for these early stages in product development there is no suitable support by means of information technology. Creativity methods like brainstorming have shown to be valuable in this phase. But in order to support them, it is very important not to influence the user's creativity by handling an intricate computer system. Thus, we introduce a system, which allows a net-based collaboration that goes far beyond today's existing technology. In addition to typical audio and video communication, intuitive interfaces like pencil or eraser allow to work simultaneously on a shared digital workspace. Therefore the presented system does not only support net-based collaboration, but also supports co-located teams to perform team sessions in the early stages on an intuitive digital basis.
