ServiceSketch: A Collaborative Tabletop Tool for Service DesignLau, Norman 01 May 2011 (has links)
ServiceSketch is a collaborative tabletop tool for service design. It was developed to address some of the challenges designers face when developing service systems, including the dynamic, intangible nature of service and the complexity of coordinating multiple stakeholders over time and space. The concept for the tool draws from literature on service design, tangible user interfaces, and co-creation. It was also informed by user research sessions with graduate design students.
The interface of ServiceSketch consists of a large multi-touch surface display that reacts to finger touches and a provided set of physical objects. Both the hardware and software development of ServiceSketch are described in this document.
ServiceSketch was evaluated with groups of graduate design students who were asked to perform small group service design activities using the tool. These sessions showed that ServiceSketch was successful in supporting common service design processes and even inspired many participants to suggest possible future developments for the tool. ServiceSketch also seemed to encourage a playful, collaborative approach to service design. The results of the project hint at the possibilities for a new breed of service design tool, one that focuses on facilitating conversations about service through an engaging, interactive medium.

SmartPads - Encouraging Children's Physical Activity Using a Multimedia Edutainment SystemHafidh, Basim 06 September 2012 (has links)
This thesis presents an exercise-based edutainment system intended for children. It is
designed to enhance their cognitive development by encouraging movement in a fun way.
The main idea behind the system is that children will have fun constructing a physical,
tangible user interface. In addition, they will learn how to spell many words that represent
objects and entities by stepping on a collection of coloured pads and receiving responses through a set of multimedia outputs related to these entities. For this purpose we have
designed and implemented a tangible user interface that facilitates interaction with the
system. This tangible user interface is called "SmartPads" and is composed of coloured tiles
that can be physically connected to each other to form any shape. The pads are mapped onto
a computer screen in real-time. A user interacts with the interface by stepping on the pads.
We have incorporated two games that allow children
of different ages to benefit from the
system's functionalities and encourage them to interact with it. This thesis provides detailed
information about the proposed system and its related components, discusses the design and
development of the two games, and measures the system's performance when used by the
children.

Påtagliga användargränssnitt för kapacitiva pekskärmar utan modifiering av enhetHabib, Ali January 2016 (has links)
Musik-applikationen c3n play används på surfplattor och mobiltelefoner som har den kapacitiva pekskärmstypen. I dagsläget kan musik-applikationen enbart styras med fingrarna. Spelpjäser, utvecklades för att målgruppen skulle kunna kombinera fingerinmatning med något fysiskt och för att underlätta spelandet. En konvergerande produktutvecklingsprocess innefattande faser och aktiviteter tillämpades. Inledningsvis genomfördes en detaljerad informationsinsamling som grund för det fortsatta arbetet. Analys av konkurrenternas produkter och en benchmarking implementerades, för att både identifiera kraven som ställts på produkten och upprätta en kravspecifikation. Spelpjäsen delades in i tre delar: formen på hela spelpjäsen, mönster som gör att användarna kan identifiera varje spelpjäs och mönster på undersidan som programvaran kunde identifiera. Därefter genererades flera idéer på formen av spelpjäsen, vilka utvärderades med hänsyn till de uppsatta kraven. Idéer som ansågs uppfylla kraven bäst gick vidare till konceptgenereringsfasen, där fem olika förslag kunde visualiseras i skisser och CAD-modeller (Computer Aidid Design). Koncepten utvärderades och förbättrades för att tillfredsställa användarnas behov och förväntningar. Det slutliga konceptet på formen gjordes i fyra olika varianter, vilka framställdes som prototyper för vidare test av målgruppen. Konceptlösningar på spelpjäsens identifieringsmönster av användaren analyserades för att passa in i c3n play-användargränssnitten. Tekniken för att identifiera spelpjäsen mot den kapacitiva pekskärmstypen utvecklades via tester, där avstånd och vinklar på kontaktpunkterna bestämdes. Viktiga produktutvecklingsverktyg implementerades för att säkerställa såväl spelpjäsernas hållbarhet som miljövänlighet, med hänsyn till produktlivscykel, tillverkning, montering och tillförlitlighet samt kostnadsmedvetenhet. Därefter valdes lämpliga material samt en lämplig tillverkningsmetod. Detta resulterade i en produktfamilj bestående av åtta stycken spelpjäser som ändrar på var sin funktion i c3n play-applikationen. En spelpjäs som förändrar amplitud, resonans, högtpassfilter, lågt-passfilter, delay, zoom + pan, kompression och feedback. / The application c3n play can be used on tablets and mobile phones that have capacitive multi touchscreens. The application can only be controlled by using the finger input. Tangible user interface was developed so the target group can use something physically “checkers” in a combination with the finger input. A product development process comprising phases and activities was implemented. Initially a detailed information collection were conducted and used as underlying to the continued work. Competitors’ products were analyzed and a benchmarking was implemented to identify user needs and to be able to make a target specification. Checkers was divided in three parts, shape of the whole checker, pattern so users can identify every checker and a pattern on the bottom so the software can identify the checkers on the screen. After that ideas were generated and the shape of the checker was evaluated. Ideas that was considered to meet the user needs went on to concept generation phase, where five different proposals was visualized in sketches and CAD (Computer Aided Design) - models. Concepts was evaluated and improved to satisfy customer needs and expectations. Final concept of the shape was developed into four different variants that was prepared as prototypes for further testing by target group. Concept solutions on identification pattern was analyzed to fit c3n play user interface. Technology to identify the checker against capacitive screen was developed by tests. Where distance and angles of contact points was determined. Important product development tools was implemented to ensure the checkers sustainability. With respect to the product life cycle, environment, manufacturing, assembly, reliability and cost consciousness. Suitable materials and manufacturing method was then chosen. Resulted in a product family consisted of eight different checkers. Each checker can change a different function in the c3n play-application. Amplitude, Resonance, Highpassfilter, Low-passfilter, Delay, Zoom + Pan, Compression and Feedback.

Exploring interactive tangrams for teaching basic school physicsJain, Nibha 24 May 2010 (has links)
This Thesis explores the application of Tangible User Interfaces to Education. For this, a research study was conducted by building and testing an interactive game called Tangram Bridge. This Tangram based game was designed to teach players about basic physics principles such as balance, friction and motion on inclined planes.
The focus of this Tangram Bridge is middle school physics, and therefore concerns children aged 11 years and up, their instructors and care givers. This research also lays a lot of emphasis on constructive play amongst children.
Tangram Bridge is a versatile platform that can be scaled for younger or older populations
A comparative study of existing Tangible User Interfaces ( TUIs) revealed opportunity spaces for this project. Through a compilation of related research in the fields of education, hands on learning, Tangible interaction and understanding play and learning amongst children, the constructionist views on learning are explored as guidelines for the design of this study.
Through the analysis of comparative research studies, trends on TUI with relation to education emerged, informing the design process for Tangram Bridge.
This research study discusses the application of Tangible user interfaces to education. It combines the research data collected through market research, user testing and literature reviews to explore the efficacy of TUI as teaching tool for abstract concepts that require imagination and experimentation.

ITG - Tangible Geometry for the Visually Impaired : Exploring the potential of extending tablet functionality with appcessoriesRühmann, Lisa Marie January 2016 (has links)
This thesis explores how an Android application that is used in combination with tangible appcessories is capable of facilitating a learning experience for visually impaired students within the specific domain of geometry. This study’s approach illustrates how using an application in combination with a physical appcessory can provide information concerning geometry to the visually impaired. An application, called Invisible Tangible Geometry (ITG), was programmed using Android in conjunction with a 3D printed model. This thesis describes the application, the physical appcessory, as well as early stage user studies. The application enables visually impaired users to explore simple geometric forms displayed on a tablet through sound and vibrotactile feedback. A physical appcessory, that can be manipulated to adopt several forms and is dynamic, is used in addition. Its shape is sensed by the tablet adds an additional tactile layer to the application and experience. Within the thesis a methodological framework, as well as a user-centered design approach was applied. An expert interview and three user engagements with visually impaired individuals serve as early validations of the project and ideas and provide feedback that directs design and development of future work. Current avenues for the future work will include additional interaction modes in the application. For example, the ability to digitize real world forms, and improving the robustness of the tangible appcessory. The plan, for future development, is to establish an autonomous functioning application that enables the visually impaired to be able to explore, participate and interact with geometry smoothly and without the need of aid from others. The correlation of application and appcessory will allow for anything between a quick glance, through feeling the model, and gaining detailed information, by using the application. The application enhances provided information through the use of a model and enriched digital feedback.

Deskové hry na interaktivním stole / Board Games on Interactive TableSvoboda, Petr January 2016 (has links)
This thesis focuses on the application of the tangible user interface and spatial augmented reality principals for playing board games. For this purpose, a system called interactive table was developed. It is both hardware and software solution. The hardware part solves the installation of a depth camera and a projector located above the table. The software solution deals with calibration of the depth camera and projector system using known procedures for camera calibration on the one hand, on the other hand it solves tasks from the field of computer vision. This perceptional part is the core of the whole thesis and for the purposes of playing board games it provides information about the location of the physical game object, physical game board and the calculations of mask for masking distracting objects. An educational application was developed for the purposes of demonstration of the system options. The interactive table offers new possibilities for playing board games in a real-world environment by the combination of the augmented reality elements with real-world objects and the related new user experience.

Exploring affordances of tangible user interfaces for interactive lightingBijman, Nicolaas Peter January 2019 (has links)
This paper explores interaction with lighting through a tangible user interface (TUI). In a TUI the physical object and space around it are part of the interface. A subset of tangible interaction called spatial interaction is the main focus of this paper. Spatial interaction refers to translation, rotation or location of objects or people within a space. The aim of this paper is to explore the relation between spatial inputs and lighting outputs based on different design properties. A user test is set up to explore the effect that design properties of a TUI have on the lighting output that participants map to spatial inputs. The results of the conducted user test indicate that communicating affordances to the user is an important factor when designing couplings between spatial inputs and lighting outputs. The results further show that the shape of the interface plays a central role in communicating those affordances and that the overlap of input and output space of the interface improves the clarity of the coupling. / Den här studien utforskar gripbar (tangible) interaktionsdesign med fokus på ljus och belysning. Vid användning av ett gripbart (tangible) gränssnitt används den fysiska miljön som gränssnitt. Detta skiljer sig till stor del från interaktion med ett grafiskt användargränssnitt, där alla interaktioner sker och begränsas av en skärms egenskaper. Denna studie fokuserar på rumslig (spatial) interaktionsdesign, vilket är en del av gripbar interaktionsdesign. Rumslig interaktion refererar till översättning, rotation eller plats av objekt eller människor i ett utrymme. Ett användartest har utförts för att testa vad för effekt olika rumsliga indata och designegenskaper har på förväntad utdata för ljus och belysning. Resultatet från användartestet visar att starka affordances och begränsningar, tillsammans med överlappningen av rumslig indata och utdata för ljus och belysning, är de viktigaste egenskaperna för att designa tydliga övergångar.

Hidden Layers of Embroidered StoriesMarkowicz, Domininka January 2022 (has links)
This paper describes the creative process of "hidden layers of embroidered stories". It shows the process of searching for answers to the questions of how to translate elements of folk culture into measurable units and how to place traditional Slavic embroidery in the context of algorithms and the digitalised world of today. It shows the process of giving meaning to a newly constructed symbol through the search for an aesthetic form, verbal designation and placement in a composition in folk crafts with seemingly rigid, well-established conventions. The final project of the project - a composition made with the use of cross-stitching encourages recipients to actively find the symbols contained within the embroidery, asking them to solve the puzzle hidden within; the solution of which carries the message of the project's author.

Tangible User Interface for CAVE based on Augmented Reality TechniqueKim, Ji-Sun 20 January 2006 (has links)
This thesis presents a new 3-dimensional (3D) user interface system for a Cave Automated Virtual Environment (CAVE) application, based on Virtual Reality (VR), Augmented Reality (AR), and Tangible User Interface (TUI). We explore fundamental 3D interaction tasks with our user interface for the CAVE system. User interface (UI) is comprised of a specific set of components, including input/output devices and interaction techniques. Our approach is based on TUIs using ARToolKit, which is currently the most popular toolkit for use in AR projects. Physical objects (props) are used as input devices instead of any tethered electromagnetic trackers. An off-the-shelf webcam is used to get tracking input data. A unique pattern marker is attached to the prop, which is easily and simply tracked by ARToolKit. Our interface system is developed on CAVE infrastructure, which is a semi-immersive environment. All virtual objects are directly manipulated with props, each of which corresponds to a certain virtual object. To navigate, the user can move the background itself, while virtual objects remain in place. The user can actually feel the prop's movement through the virtual space. Thus, fundamental 3D interaction tasks such as object selection, object manipulation, and navigation are performed with our interface. To feel immersion, the user is allowed to wear stereoscopic glasses with a head tracker. This is the only tethered device for our work. Since our interface is based on tangible input tools, seamless transition between one and two-handed operation is provided. We went through three design phases to achieve better task performance. In the first phase, we conducted the pilot study, focusing on the question whether or not this approach is applicable to 3D immersive environments. After the pilot study, we redesigned props and developed ARBox. ARBox is used for as interaction space while the CAVE system is only used for display space. In this phase, we also developed interaction techniques for fundamental 3D interaction tasks. Our summative user evaluation was conducted with ARDesk, which is redesigned after our formative user evaluation. Two user studies aim to get user feedback and to improve interaction techniques as well as interface tools' design. The results from our user studies show that our interface can be intuitively and naturally applied to 3D immersive environments even though there are still some issues with our system design. This thesis shows that effective interactions in a CAVE system can be generated using AR technique and tangible objects. / Master of Science
