This paper reflects upon our attempts to bring a participatory design approach to design research into interfaces that better support dental practice. The project brought together design researchers, general and specialist dental practitioners, the CEO of a dental software company and, to a limited extent, dental patients. We explored the potential for deployment of speech and gesture technologies in the challenging and authentic context of dental practices. The paper describes the various motivations behind the project, the negotiation of access and the development of the participant relationships as seen from the researchers' perspectives. Conducting participatory design sessions with busy professionals demands preparation, improvisation, and clarity of purpose. The paper describes how we identified what went well and when to shift tactics. The contribution of the paper is in its description of what we learned in bringing participatory design principles to a project that spanned technical research interests, commercial objectives and placing demands upon the time of skilled professionals.

O lava-pés em Jo 13,1-17 é objeto dessa tese que tem por objetivo apresentar sua significação cultural e sociorreligiosa. Em meio à complexidade do caráter polissêmico do relato joanino o foco da análise volta-se para o contexto das características do costume cultural implicados no lava-pés em ambiente de refeição no mundo mediterrâneo do primeiro século da EC. Com base na análise da história da redação o relato joanino é apresentado como fruto de um processo de recuperação da memória tradicional para ressignificar o valor e dignidade do lava-pés e dos sujeitos aos quais essa tarefa era atribuída: mulheres, escravos e crianças. No contexto da comunidade joanina o lava-pés transforma-se em proposta não apenas de renúncia ou inversão de status, mas de reciprocidade de papéis assumida por todos como gesto concreto e, ao mesmo tempo, simbólico, de abolição de qualquer discriminação ou desigualdade que possa existir entre as pessoas. O lava-pés, nos dois estratos que descrevem as primeiras interpretações predominantes na comunidade (Jo 13, 12-17 e Jo 13,6-10), não é, pois, ritual religioso de purificação de pecado, nem apenas o testemunho de um serviço humilde de quem renuncia provisoriamente ao seu status, mas sim a expressão da identidade de um discipulado que pretende viver um igualitarismo radical no cotidiano do exercício de poder e da divisão de suas tarefas.

This thesis describes the work carried out on the development of a novel digit actuator system with tactile perception feedback to a user and demonstrated as a master-slave system. For the tactile surface of the digit, contrasting sensor elements of resistive strain gauges and optical fibre Bragg grating sensors were evaluated. A distributive tactile sensing system consisting of optimised neural networking schemes was developed, resulting in taxonomy of artificial touch. The device is suitable for use in minimal invasive surgical (MIS) procedures as a steerable tip and a digit constructed wholly from polymers makes it suitable for use in Magnetic Resonance Imaging (MRI) environments enabling active monitoring of the patient during a procedure. To provide a realistic template of the work the research responded to the needs of two contrasting procedures: palpation of the prostate and endotracheal intubation in anaesthesia where the application of touch sense can significantly assist navigation. The performance of the approach was demonstrated with an experimental digit constructed for use in the laboratory in phantom trials. The phantom unit was developed to resemble facets of the clinical applications and digit system is able to evaluate reactive force distributions acting over the surface of the digit as well as different descriptions of contact and motion relative to the surface of the lumen. Completing control of the digit is via an instrumented glove, such that the digit actuates in sympathy with finger gesture and tactile information feedback is achieved by a combination of the tactile and visual means.

Mobile and wearable computers present input/output prob-lems due to limited screen space and interaction techniques. When mobile, users typically focus their visual attention on navigating their environment - making visually demanding interface designs hard to operate. This paper presents two multimodal interaction techniques designed to overcome these problems and allow truly mobile, 'eyes-free' device use. The first is a 3D audio radial pie menu that uses head gestures for selecting items. An evaluation of a range of different audio designs showed that egocentric sounds re-duced task completion time, perceived annoyance, and al-lowed users to walk closer to their preferred walking speed. The second is a sonically enhanced 2D gesture recognition system for use on a belt-mounted PDA. An evaluation of the system with and without audio feedback showed users' ges-tures were more accurate when dynamically guided by au-dio-feedback. These novel interaction techniques demon-strate effective alternatives to visual-centric interface de-signs on mobile devices.

On the morning of January 5, 1859, at the end of the liturgy in the Orthodox cathedral in Iaşi, the capital of the principality of Moldavia, Father Neofit Scriban addressed the congregation. He had given many sermons in the cathedral; however, on this par tic u lar date Father Neofit faced an unusual audience. Among the faithful who regularly worshipped at the relics of Saint Parascheva, the protector of Moldavia, were the members of the assembly who would decide the future of the principality. They had a specific mission: to elect a new prince, a key figure in their plan to unite Moldavia with the neighboring principality of Wallachia. Father Neofit, a supporter of the unionist cause and fully aware of the significance of the moment, stated: Brethren, Jesus Christ has said that "For where two or three have gathered together in My name, I am there in their midst." You, Brethren, are not two, or three, but a real gathering in the name of God. God is in your midst. You are here in the name of the Romanian nation [and] the Romanian nation is in your midst. On the flag under which you have assembled, the flag of the Romanian nation, great events, the Romanian faith, unity, are written in large letters. The church, which is founded on faith, blesses the flag of this faith⋯. You, Brethren, through the faith of the Romanian nation, by remaining faithful to this flag, will find the same strength as the church [finds] in its own saints. The faith of the Romanian nation was not, is not, and will not be anything else, but the unity of all Romanians in a single state, the only anchor of salvation, the only port in which the national boat could be saved from surrounding waves. You, Brethren, have gathered here in the church of Stephen the Great; looking at the altar that he raised to the God of your parents, I think that, through this [altar], you will be able to enter into the wishes of this hero of our nation. You, [remember that] by leaving this place, you are leaving [in order to fulfill] a great gesture that for many centuries has been lost for us; you are about to elect a successor to this great hero; therefore, as his true sons, you could not be anything other than the true expression of his wishes. Myself, [as] last year, from this altar, I said and I will continue to say that this great hero has told us that "the God of our parents will send us a Redeemer who will heal our wounds and accomplish our wishes." May your chosen leader today be the redeemer expected by the Romanian nation. May he heal its wounds and achieve its wishes. Therefore, Brethren, may your election today be that of a real Messiah of Romania. God and the world are looking at you, the church is blessing you and the whole Romanian nation is waiting for you!1 A few hours after Father Neofit's sermon, the assembly elected Alexandru Ioan Cuza to be the prince of the principality of Moldavia; a few days later, on January 24, 1859, the assembly of the neighboring principality of Wallachia decided that Cuza should also be their prince, thus confirming the unification of the two states. A new country was inscribed on the map of Southeastern Europe, titled "The United Principalities of Wallachia and Moldavia," also known as "The United Romanian Principalities".

With the introduction of new input devices, such as multi-touch surface displays, the Nintendo WiiMote, the Microsoft Kinect, and the Leap Motion sensor, among others, the field of Human-Computer Interaction (HCI) finds itself at an important crossroads that requires solving new challenges. Given the amount of three-dimensional (3D) data available today, 3D navigation plays an important role in 3D User Interfaces (3DUI). This dissertation deals with multi-touch, 3D navigation, and how users can explore 3D virtual worlds using a multi-touch, non-stereo, desktop display. ^ The contributions of this dissertation include a feature-extraction algorithm for multi-touch displays (FETOUCH), a multi-touch and gyroscope interaction technique (GyroTouch), a theoretical model for multi-touch interaction using high-level Petri Nets (PeNTa), an algorithm to resolve ambiguities in the multi-touch gesture classification process (Yield), a proposed technique for navigational experiments (FaNS), a proposed gesture (Hold-and-Roll), and an experiment prototype for 3D navigation (3DNav). The verification experiment for 3DNav was conducted with 30 human-subjects of both genders. The experiment used the 3DNav prototype to present a pseudo-universe, where each user was required to find five objects using the multi-touch display and five objects using a game controller (GamePad). For the multi-touch display, 3DNav used a commercial library called GestureWorks in conjunction with Yield to resolve the ambiguity posed by the multiplicity of gestures reported by the initial classification. The experiment compared both devices. The task completion time with multi-touch was slightly shorter, but the difference was not statistically significant. The design of experiment also included an equation that determined the level of video game console expertise of the subjects, which was used to break down users into two groups: casual users and experienced users. The study found that experienced gamers performed significantly faster with the GamePad than casual users. When looking at the groups separately, casual gamers performed significantly better using the multi-touch display, compared to the GamePad. Additional results are found in this dissertation.^

This dissertation seeks to reflect about the relations between danced movement and body space (Kinesphere), and their contributions to the expansion of the expressive possibilities of the subject on dancing. According to Rudolf Laban there is no space that is empty, because it is always being modified and signified at every moment by the movement. Space exists because we interact with it, at the same time movement occours configuring a signifcant space that is incessantly transformed. In this sense, space, body and movement appear in this research as interconnected and interdependent. For this discussion we have as main interlocutor the studies of Rudolf Laban. The nature of this research is qualitative and descriptive. This is a context that embraces the phenomenon of dance and as such it is based on a dimension that doesn't deal with mensurability, but with the art scene, fruitful in its infinite openness to the creation of multiple significances for what has been lived. We also propose to present a report about the practical study developed in the discipline Coreologia in the licentiate course of Dance in UFRN, as well as the analysis of the interviews applied to students of this curricular component. The questions were developed in a way that lead to a reflection about the experience of those interviewed in this discipline, thus generating material for us to discuss how the students perceive dance based on the relational study between space and movement. We realize that this study may favor an understanding of the relations that the experienced movement in the act of the dance weaves along the spatiality that receives and fills our bodies, resignifying the vision of a space which is restrict to the mere place were the body moves and occupies. It also favors the reflections concerning the body that moves and creates spatiality when dancing, thereby bringing to the Performing Arts a chance to think and to experience on the expansion of the expressive gesture in dance and beyond it, led by the recognition of the principles that organize human movement pointed by Laban. It also contributes on the formation of the students in licentiate courses of Dance by questioning the ways to appropriate the contents worked in a graduation discipline as regards to the availability of the body for dance. This dissertation is divided in three parts, called Impulsos. In the First Impulso: “Primeiros Gestos Textuais”, we find an introduction to concepts and ideas of body, movement and space that permeates all the work. In the Second Impulso: "Nós", the triad body-space-motion is discussed using the metaphorical image of a knot that binds these three concepts. The third and final Impulso: "Enlaces" deal with impressions and discoveries lived during the experimentation of the principles of inter-actions studied here, in the lessons of the already mentioned discipline

This dissertation presents an investigation of the evolutionary process of extended oboe techniques, through literary analysis and practical research. The objective of this work is to provide assistance to oboists interested in learning these techniques. Additionally, this work encourages the student, through the process of experimentation, to explore the questions that may arise around the aesthetics of sound, the concept of gesture as an additional visual and aural element in music, and the collaboration and “real-time” creation processes. Discussed within the work, are the relationship between the instrument (the oboe) and extended techniques, and two possible definitions of extended techniques, provided by Luk Vaes (2009) and Gardner Read (1993). Also explored are the how and why some composers have utilized extended techniques in their compositions, including brief discussions relating to extended techniques in real-time composition (improvisation), extended techniques and technological resources, theatrical gesture as an extended technique, and suggestions of how musicians might approach theatrical gestures in performance. Four works were visited: “I Know This Room So Well” – Lisa Bielawa (2007-9); “Four Pieces for Oboe and Piano” – Ernst Krenek (1966); “In Freundschaft” – Karlheinz Stockhausen (1978); “Atem” – Mauricio Kagel (1969-70); and an exploration of the difficulties and solutions associated with each extended technique found within these pieces, was carried out. The following founding works on extended oboe techniques were used, as a basis for research: books - Heinz Holliger’s Pro Musica Nova (1972); Gardner Read’s Compendium of Modern Instrumental Techniques (1993); Peter Veale & Claus-Steffen Mahnkopf’s The Techniques of Oboe Playing (1994); and Libby Van Cleve’s Oboe Unbound: Contemporary Techniques (2004); and articles - Nora Post’s “Monophonic sound resources for the oboe: Part I – Timbre” (1984), “Part II- Pitch and other techniques” (1984), and “Multiphonics for the oboe” (1982).

This study aims to document the preparation process for the implementation of "Cantata To Praise and Glory"(Cantata Para Louvor e Glória), composed in 1985 by composer Cleide Dorta Benjamin (1936 - ), in order to anticipate and address the possible difficulties faced by future conductors, singers and instrumentalists. Issues that relate to the chosen text as well as its structure and importance in the compositional process, are initially addressed through a brief presentation of the work. Consequently, by addressing every detail of the work, solutions to vocal and instrumental execution difficulties, as well as with the conducting gesture, are analyzed, identified and proposed. The work also presents a report that describes all the practical processes of preparation of the Cantata: reissue of the score; selection and profile of singers and instrumentalists; rehearsals; changes and adjustments to the score; and a brief interview with four singers and two musicians who participated in the process. The interaction with the composer throughout a significant part of the work, brings a notable increase of possible clarifications and idea development, enabling a coherent performance of the work.

This work is the result of a master’s program research developed in the post graduation program in music at the Music School of the UFRN ( Federal University of Rio Grande do Norte) under the orientation of Dr. Andre Luiz Muniz de Oliveira which aimed at making a reflexion about regency gestures and its implications about the objective and subjective elements of the performance connected to a number of regency tools concieved in accordance with the tradition of historic music. As a tool for gestual analysis we’ve used the Harold Farbermann PatternCube method. We’ve used videos from conductors Pierre Boulez e Valery Gergiev, both conducting Igor Stravinsky’s Rite of Spring. In the analysis of the videos we’ve observed the technical use of the gestual aparatus instead of the use of musical gestures fundamented in Hatten. The research showed us the importance of the use of analitical tools in helping subsidise a direction in performance in regency.

The main objective of this work was to enable the recognition of human gestures through the development of a computer program. The program created captures the gestures executed by the user through a camera attached to the computer and sends it to the robot command referring to the gesture. They were interpreted in total ve gestures made by human hand. The software (developed in C ++) widely used the computer vision concepts and open source library OpenCV that directly impact the overall e ciency of the control of mobile robots. The computer vision concepts take into account the use of lters to smooth/blur the image noise reduction, color space to better suit the developer's desktop as well as useful information for manipulating digital images. The OpenCV library was essential in creating the project because it was possible to use various functions/procedures for complete control lters, image borders, image area, the geometric center of borders, exchange of color spaces, convex hull and convexity defect, plus all the necessary means for the characterization of imaged features. During the development of the software was the appearance of several problems, as false positives (noise), underperforming the insertion of various lters with sizes oversized masks, as well as problems arising from the choice of color space for processing human skin tones. However, after the development of seven versions of the control software, it was possible to minimize the occurrence of false positives due to a better use of lters combined with a well-dimensioned mask size (tested at run time) all associated with a programming logic that has been perfected over the construction of the seven versions. After all the development is managed software that met the established requirements. After the completion of the control software, it was observed that the overall e ectiveness of the various programs, highlighting in particular the V programs: 84.75 %, with VI: 93.00 % and VII with: 94.67 % showed that the nal program performed well in interpreting gestures, proving that it was possible the mobile robot control through human gestures without the need for external accessories to give it a better mobility and cost savings for maintain such a system. The great merit of the program was to assist capacity in demystifying the man set/machine therefore uses an easy and intuitive interface for control of mobile robots. Another important feature observed is that to control the mobile robot is not necessary to be close to the same, as to control the equipment is necessary to receive only the address that the Robotino passes to the program via network or Wi-Fi.
