Bluetooth has been selected, because we decided for the current experimental system to run the application software not only on the server but also on the FTs (see, chapter 2.3). Therefore only position and orientation have to be transmitted for which a small bandwidth is sufficient. In the future the communication will move to wireless LAN. application server tracking server tracking camera camera signal FT ID, position and rotation application data FT overview table Fig. 7. System architecture of the digital map table For reference calculation between work table and FTs the MC-MXT tracker must be calibrated. During the calibration process the coordinate transformation between the tracking camera images, which are the input for the MC-MXT tracker, and the viewer of the work table is calculated. In a first step, that has to be carried out only once for the whole table arrangement, the camera image gets referenced to the overview table. Therefore an calibration image with four defined cross points is projected onto the table. Each cross point is identified by its own colour. Four special MC-MXT calibration markers, only used within the calibration process, are marked with the same colors and laid on the projected cross points. So the camera »knows« the size of the overview table and the size of the markers. The second step has to be carried out for every Fovea-Tablett separately. For an FT calibration two images of the FT with the fixed identity marker are taken, whereby the FT has to be positioned on two defined regions of the work table. These regions are also indicated by the calibration image. 2.3 Interaction interaction techniques and a flexible software infrastructure which enables easy integration information sources and interaction devices.

By 1991 signalling will be fully computerised and monitored from the Line Control Room at Baker Street. At the present time, the Bakerloo Line Control Room houses the Line Controller, who coordinates the day to day running of the railway and the Divisional Information Assistant (DIA) whose responsibilities include providing information to passengers through a public address (PA) system and communicating with station managers.

The Bakerloo Line Control Room The Controller and DIA sit together at a semicircular console which faces a tiled, real time, hard line display which runs nearly the entire length of the room and shows traffic movement along the Bakerloo Line (from the Elephant and Castle to Queens Park). The console includes touch screen telephones, a radio system for contact with drivers, the PA control keys, and close circuit television (CCTV) monitors and controls for viewing platforms (see Figure 2).

Level indicators are in passive mode (left) until the tangible is detected (right). An example of tangible control elements on interactive tabletop ems is presented by Weiss et al. [13] who introduce “Silicon minated Purpose” (SLAP) Widgets. The widget set consists of tipurpose tangibles including a slider element. In an empirical dy the physical widgets were tested against respective direct- ch concepts. Physical control elements outperformed the ual control elements regarding accuracy and overall raction time. “Madgets” [14], a continuation of the passive AP widget set, can actively synchronize with the system’s state thereby avoid inconsistencies. Hennecke et al. [2] investigated several adhesion techniques materials to place tangibles on vertical displays. The hniques were considered under design criteria typical to ractive displays, such as the support of several tracking hnologies or reusability of the tangible. As a result, applying uum-based adhesion turned out to be the best solution. OPERATING CONCEPTS The presented post-WIMP concepts for the manipulation of cess variables were designed under the tradeoff consideration uggested by Jacob et al. [5]. In order to investigate the effects he tradeoff decisions, operating concepts were designed for input modalities with different power and reality proportions: ngible-object and a direct-touch concept. As common actuator For the rotatory control concept (Figure 4, top) the digital level indicator appears in a concentric circle around the contact area. The shape of the level indicator corresponds to a bent triangle, which emphasizes the direction code. In the sense of readability Müller, Jens, et al.

Furthermore, the exploratory nature of our work meant that we were to preliminarily evaluate ideas and eliminate potential culs-de-sac. Overall, we were guided by the need to provide the means for rapid coordination of multiple resources within a temporal dimension. We aimed to make the interaction intuitive enough to move the focus from the planning table to the actual units in the field and effectively utilizing the knowledge of the experts.

As a physical reminder, she holds the EZY4262 strip in her left hand so she won’t forget to send it to the tower controller. Augmented strips as a mix of virtual and physical media. The system provides a hybrid artifact, in which paper and digital media are identical and have equal importance. When one controller holds a paper strip, the other controllers can use the digital pen to interact with its virtual twin: They can write on it or move it by dragging on its border. When repositioning the paper strip on the board, the virtual strip is aligned under it. The then obscured handwritten notes of the virtual strip are projected onto the paper strip. The system lets the controller extend the physical strip virtually. Thirty minutes later, the traffic gets quite intense, so Tessa’s sector needs to be split up. Two colleagues are on standby in the control room. Tessa initiates the degrouping mode in the system. She decides to hand off the area around the spatial arrangements of strips help (Top) A controller collaboratively optimizes an arrival sequence, using a paper strip, numeric pen, and projected information.

Figure 13: tangible strips (b) acting as controls and as containers for augmented data (a) and as representations and tokens for cognitive elements (c). Implications for allocation of physical and virtual components This analysis sheds light on our choices of allocation. As we described in the previous section, physical objects and associated manipulations have their inner coherence. So, as long as physical objects are able to provide the controller with external representations of their concerns, there is no need to overload them with additional explicit information. As described in the previous section, physical and spatial tools provide a sufficient encoding of objective time, orders and internal clock. By contrast, augmented data (Figure 13a) are needed to provide real-time perception and dynamic information on the current state of flights. Our analysis also helps to understand potential complexity issues, where the physical manipulations, such as tangible computation of stack exit times, did not exactly correspond to current practices, i.e., at least for some controllers, to externalizations on which they rely today. A seamless and understandable interactive space Complexity is also dealt with through the properties and the behavior of the components. Several of our observations and projected data. 2) merged displays: projected data cannot occlude printed information and vice versa, which adds to this seamless combination of tangible and virtual dimensions. Finally, coherence in Strip’TIC does not assume a constant coupling between physical and virtual components: disrupting strip tracking by removing a strip from the board does not prevent continuous use of the system, and most importantly, disrupting Anoto does not break the system either, since handwriting still works. CONCLUSION The Strip’TIC system provides us with the ability to explore mixed interaction in a context where physical interactions are effective and secure. Throughout our design reflections, we have seen that unlike usual TUI approaches, which rely on mapping and coupling of physical objects to virtual objects, coherence in Strip’TIC is based on other aspects. First, it relies on the mapping of virtual to physical objects that play a primary role as externalization of controllers internal concerns. Second, coherence consequently relies on a seamless connection of cognitive and tangible spaces that help the users to build a physical and virtual image of the situation. Third, the properties of the interactive space components and continuous feedback help users understand the mixed behavior of the system. Thus, compared to existing TUI models, our approach is complementary: we include the understanding and integration of artefact cognitive mechanisms as part of our design choices. Future work involves exploring issues about how augmented data may support externalization too, since this matter seems to be overlooked in current research. We also plan to investigate further about multitouch gestures combined with handwriting and pen-based interaction.
