Thesis (M.S.)--Boston University / Problem: To acquire knowledge of the organization and administrative methods of departments of audio-visual education in the greater Boston area. Method of Study: Nine departments of audio-visual education in the greater Boston area were selected for study. In the selection of these departments, an attempt was made to obtain coverage of as wide a variety of audio-visual departments as possible which serve different segments of the public. These selected departments could be expected to exhibit different approaches, organizational and administrative methods. In collecting the data for this thesis, the writer visited each of the following nine departmental Film Library Boston University School of Education; Department of Audio-Visual Instruction, Boston Public Schools; Audio-Visual Department, Boston Public Library; Audio-Visual Department, Lexington Public Schools; Department of Audio-Visual Instruction, New Bedford Public Schools; Audio-Visual Center New England Bell Telephone and Telegraph Company; Department of Audio-Visual Aids, North Reading Public Schools; Department of Audio-Visual Instruction, Weymouth Public Schooler and the Audio-Visual Department, Newton Public Schools. The writer interviewed the audio-visual director of each department, and examined the physical facilities [TRUNCATED]

Depuis quelques années, un intérêt grandissant pour les interactions homme-robot (HRI), avec pour but de développer des robots pouvant interagir (ou plus généralement communiquer) avec des personnes de manière naturelle. Cela requiert aux robots d'avoir la capacité non seulement de comprendre une conversation et signaux non verbaux associés à la communication (e.g. le regard et les expressions du visage), mais aussi la capacité de comprendre les dynamiques des interactions sociales, e.g. détecter et identifier les personnes présentes, où sont-elles, les suivre au cours de la conversation, savoir qui est le locuteur, à qui parle t-il, mais aussi qui regarde qui, etc. Tout cela nécessite aux robots d’avoir des capacités de perception multimodales pour détecter et intégrer de manière significative les informations provenant de leurs multiples canaux sensoriels. Dans cette thèse, nous nous concentrons sur les entrées sensorielles audio-visuelles du robot composées de microphones (multiples) et de caméras vidéo. Dans cette thèse nous nous concentrons sur trois tâches associés à la perception des robots, à savoir : (P1) localisation de plusieurs locuteurs, (P2) localisation et suivi de plusieurs personnes, et (P3) journalisation de locuteur. La majorité des travaux existants sur le traitement du signal et de la vision par ordinateur abordent ces problèmes en utilisant uniquement soit des signaux audio ou des informations visuelles. Cependant, dans cette thèse, nous prévoyons de les aborder à travers la fusion des informations audio et visuelles recueillies par deux microphones et une caméra vidéo. Notre objectif est d'exploiter la nature complémentaire des modalités auditive et visuelle dans l'espoir d'améliorer de manière significatives la robustesse et la performance par rapport aux systèmes utilisant une seule modalité. De plus, les trois problèmes sont abordés en considérant des scénarios d'interaction Homme-Robot difficiles comme, par exemple, un robot engagé dans une interaction avec un nombre variable de participants, qui peuvent parler en même temps et qui peuvent se déplacer autour de la scène et tourner la tête / faire face aux autres participants plutôt qu’au robot. / In recent years, there has been a growing interest in human-robot interaction (HRI), with the aim to enable robots to naturally interact and communicate with humans. Natural interaction implies that robots not only need to understand speech and non-verbal communication cues such as body gesture, gaze, or facial expressions, but they also need to understand the dynamics of the social interplay, e.g., find people in the environment, distinguish between different people, track them through the physical space, parse their actions and activity, estimate their engagement, identify who is speaking, who speaks to whom, etc. All these necessitate the robots to have multimodal perception skills to meaningfully detect and integrate information from their multiple sensory channels. In this thesis, we focus on the robot's audio-visual sensory inputs consisting of the (multiple) microphones and video cameras. Among the different addressable perception tasks, in this thesis we explore three, namely; (P1) multiple speakers localization, (P2) multiple-person location tracking, and (P3) speaker diarization. The majority of existing works in signal processing and computer vision address these problems by utilizing audio signals alone, or visual information only. However, in this thesis, we plan to address them via fusion of the audio and visual information gathered by two microphones and one video camera. Our goal is to exploit the complimentary nature of the audio and visual modalities with a hope of attaining significant improvements on robustness and performance over systems that use a single modality. Moreover, the three problems are addressed considering challenging HRI scenarios such as, eg a robot engaged in a multi-party interaction with varying number of participants, which may speak at the same time as well as may move around the scene and turn their heads/faces towards the other participants rather than facing the robot.

abstract: Several music players have evolved in multi-dimensional and surround sound systems. The audio players are implemented as software applications for different audio hardware systems. Digital formats and wireless networks allow for audio content to be readily accessible on smart networked devices. Therefore, different audio output platforms ranging from multispeaker high-end surround systems to single unit Bluetooth speakers have been developed. A large body of research has been carried out in audio processing, beamforming, sound fields etc. and new formats are developed to create realistic audio experiences. An emerging trend is seen towards high definition AV systems, virtual reality gears as well as gaming applications with multidimensional audio. Next generation media technology is concentrating around Virtual reality experience and devices. It has applications not only in gaming but all other fields including medical, entertainment, engineering, and education. All such systems also require realistic audio corresponding with the visuals. In the project presented in this thesis, a new portable audio hardware system is designed and developed along with a dedicated mobile android application to render immersive surround sound experiences with real-time audio effects. The tablet and mobile phone allow the user to control or “play” with sound directionality and implement various audio effects including sound rotation, spatialization, and other immersive experiences. The thesis describes the hardware and software design, provides the theory of the sound effects, and presents demonstrations of the sound application that was created. / Dissertation/Thesis / Masters Thesis Electrical Engineering 2016

Orientador: Omar Khouri / Banca: José Leonardo do Nascimento / Banca: Lúcio Agra / Resumo: A partir da vídeo-documentação do Projeto Tecer, uma experiência de convivência com crianças denominadas autistas, o presente trabalho faz uma pesquisa na história do cinema e da arte buscando aproximações possíveis entre documentário e obra artística. A documentação teve dois focos, por um lado auxiliar no desenvolvimento do Projeto Tecer, por outro criar uma obra áudio-visual capaz de modificar a imagem das crianças autistas perante a sociedade. A pesquisa, que envolve um estudo sobre os filmes "O homem com uma Câmera", de Dziga Vertov, "Nanook of the North", de Robert J. Flaherty, e "Crônica de um Verão" de Jean Rouch e Edgard Morin, procura identificar aspectos artísticos do fazer cinematográfico documentário. Trata-se de filmes que trazem uma elaboração poética da linguagem cinematográfica, e, mesmo sendo considerados documentários, absorveram métodos e técnicas típicas do cinema ficcional. Tradicionalmente, o filme documentário explora uma relação com a realidade. O desenvolvimento da linguagem documentária possibilitou que essa relação ficasse cada vez mais clara na obra, ao ponto de o próprio cineasta aparecer na tela, como ocorre em "Crônica de um Verão", evidenciando que o cineasta se modifica e modifica o objeto que retrata na medida em que realiza a obra. Tendo consciência da história e dos métodos de produção áudio-visual o presente trabalho apresenta o filme "Entre nós", que é o resultado da documentação de cinco anos do Projeto Tecer. Um vídeo-documentário que procura reconstruir a experiência de conviver com crianças autistas de acordo com o olhar do documentalista. / Abstract: Starting from the video-documentation of the Tecer Project, a living along experience with autistic called children, the present work makes a research about the history of the cinema and the art, searching for possible approaches between documentary films and artworks. The documentation had two focuses, to assist the development of the Tecer Project, and to create a film capable of modifying the image of the autistic children in the society. The research, that involves a study on the films "The Man with the Movie Camera", from Dziga Vertov, "Nanook of the North", from Robert J. Flaherty, and "Chronicle of a Summer" from Jean Rouch and Edgard Morin, tries to identify artistic aspects of the making of cinematographic documentaries. These are films witch bring a poetical elaboration of the cinematographic language, and, even being considered documentaries, they absorbed methods and typical techniques of the fictional cinema. Traditionally, the documentary film explores a relation with the reality. The development of the documentary language made possible that this relation could be clearer in the artwork, to the point of proper film maker to appear in the screen, as occurs in "Chronicle of a Summer", evidencing that the film maker modifies himself, and modifies the object that he shoots, while filming it. Having conscience of the history and methods of audio-visual production, the present work presents the film "Entre Nós", witch is the result of a five year documentation of the Tecer Project. A video-documentary that reconstructs the experience of living along with autistic children, according to the vision of the documentary film maker. / Mestre
