acto a modular actuated tangible User Interface Object
Interactive Tabletops and Surfaces, 2014Co-Authors: Emanuel Vonach, Georg Gerstweiler, Hannes KaufmannAbstract:We introduce a customizable, reusable actuated tangible User Interface Object: ACTO. Its modular design allows quick adaptations for different scenarios and setups on tabletops, making otherwise integral parts like the actuation mechanism or the physical configuration interchangeable. Drawing on the resources of well-established maker communities makes prototyping especially quick and easy. This allows the exploration of new concepts without the need to redesign the whole system, which qualifies it as an ideal research and education platform for tangible User Interfaces. We present a detailed description of the hardware and software architecture of our system. Several implemented example configurations and application scenarios demonstrate the capabilities of the platform.

mark up language implementation of graphical or non graphical User Interfaces
2000Co-Authors: Terry Don JenningsAbstract:Interface description documents define the appearance and behavior of a User Interface (132) toward the User, and feature description documents define interaction of the Interface with the Interfaced-to application, both in conformity with a User-Interface Object model (310). Connector and layout Object plug-ins (126, 128) define connector and layout Objects for rendering elements of feature and Interface description documents, respectively; of one or more Interfaces. An interactor (130), independent of any Interface or Interface type, the application, and the User device (100,200), generates User Interfaces from the stored information. The interactor parses the description documents of an Interface into elements and reflects them in the Object model to form an instance representing the Interface, downloads the Objects corresponding to the reflected elements registers their Interfaces in the Object model instance to make them accessible by the elements, and invokes execution of each downloaded Object with the corresponding element to render the element.

Speckle Tracking : ACTO tracking with optical mouse sensors
'Universidad Norbert Wiener', 2016Co-Authors: Bernhardt DanielAbstract:Abweichender Titel nach Übersetzung der Verfasserin/des VerfassersZusammenfassung in englischer SpracheDer Einsatz von Tangible User Interfaces (TUIs) erscheint, unter anderem aufgrund ihrer häufig sehr intuitiven Bedienung (z.B. Computermaus, Lenkrad etc.) und der spielerischen Komponente, sowohl im medizinischen Bereich, als auch in der Entertainmentsparte vielversprechend. TUIs können mit Aspekten mobiler Roboter ergänzt werden, um Feedback in Form einer selbständigen Positionsänderung zu ermöglichen. Mit diesen gesteuerten (engl. actuated) TUIs beschäftigt sich das ACTO-Projekt (kurz für Actuated Tangible User Interface Objects [3]). Das Resultat sind kleine, würfelförmige Roboter - genannt ACTOs. Jedes ACTO ist modular aufgebaut und kann, zusätzlich zum Bewegungsmodul, mit verschiedenen Input- und Output-Erweiterungen bestückt werden. Um die Bewegungen der ACTOs zentral zu steuern und zu koordinieren, muss deren Position in Echtzeit bestimmt werden. Jede Art der Positionsbestimmung hat ihre eigenen Vor- und Nachteile. Bisher fand die Positionsbestimmung ausschließlich durch das optische Tracking eines Markers auf der Unterseite jedes ACTOs statt. Diese Form des Trackings liefert zwar recht präzise und absolute Positionswerte, zeigt allerdings Schwächen bei schlechter Beleuchtung und zu schnellen Bewegungen des ACTOs. Um diese Nachteile zu kompensieren, stellt diese Arbeit eine Erweiterung vor, die das Tracking durch zwei, an jedem ACTO befestigte, optische Maussensoren ergänzt. Dabei wird die Verschiebung entlang der X- und Y-Achse beider Sensoren ausgelesen. Aus diesen Werten wird mittels eines Algorithmus, die Translation und Rotation des ACTOs und damit dessen neue Position bestimmt. Die Arbeit beschreibt die Design-Überlegungen und die Konstruktion dieses relativen Tracking-Systems. Dabei wird auf die Entwicklung der Hard- und Software eingegangen. Die mathematischen Hintergründe werden ebenfalls beleuchtet. Schlussendlich wird gezeigt, dass die Ergänzung des absoluten Trackings durch optische Maussensoren, im Bezug auf Präzision und Robustheit, sowie bei schnellen Bewegungen bestechende Vorteile bietet. Das System besteht aus günstigen, handelsüblichen Bauteilen und ist gut in das bestehende ACTO-System integrierbar. Damit erscheint der Einsatz des Systems in den verschiedensten Forschungsgebieten sinnvoll. Da sich während der Arbeit an den einzelnen Prototypen und dem Schreiben der Software außerdem ein großes Potential für weitere Modifikationen zeigte, mit denen das System an die verschiedensten Umgebungen und Herausforderung angepasst werden kann, wird abschließend auch auf diese Verbesserungen eingegangen.The use of Tangible User Interfaces (TUIs) for medical and entertainment purposes seems promising because of their mostly very intuitive handling and playful aspect (computer mouse, steering wheel, etc.). TUIs can be supplemented with elements of mobile robots to allow independent movement as feedback. The Actuated Tangible User Interface Object-project (ACTO [3]) is focused on these actuated TUIs, resulting in cubic robots called ACTOs. Every ACTO is modularly composed and, in addition to the movement unit, can be equipped with a variety of input and output extensions. To control and coordinate the movement of the ACTOs, their position needs to be retrieved in real time. Every method of determining an ACTO-s position has its own advantages and disadvantages. Until now, the position was obtained by the optical tracking of a marker at the ACTO-s bottom. This tracking method provides precise, absolute tracking data but cannot cope with poor illumination or movement which is too fast. To compensate for these shortcomings, this thesis introduces an extension which supplements the existing tracking system by another tracking method based on two optical mouse sensors. In this process the translation along the X- and Y-axis is read from both sensors. Based on these four translation values, the ACTO-s translation and rotation and therefore its new position is computed. The thesis discusses the ideas leading to the design and construction of this relative tracking system and therefore elaborates on the development of the hard- and software, as well as the mathematical background. In the end it is shown that the supplement of the absolute tracking by the relative tracking based on two optical mouse sensors provides considerable advantages in terms of precision and robustness. The system is composed of low-priced, off-the-shelf components and is easily integrated into the existing ACTO system. Thus, the use of this system seems promising in various research areas. During the work on several prototypes and the coding of the software, great potential for more modifications and adaptions to various environments was revealed which is discussed in the last part of this thesis.10
