  1. Resynthesizing reality : driving vivid virtual environments from sensor networks

    Haddad, Don Derek
    The rise of ubiquitous sensing enables the harvesting of massive amounts of data from the physical world. This data is often used to drive the behavior of devices, but when presented to users, it is most commonly visualized quantitatively, as graphs and charts. Another approach for the representation of sensor network data presents the data within a rich, virtual environment. This thesis introduces the concept of Resynthesizing Reality through the construction of Doppelmarsh, the virtual counterpart of a real marsh located in Plymouth Massachusetts, where the Responsive Environments Group has deployed and maintained a network of environmental sensors. By freely...

  2. AirTap : a multimodal interactive interface platform with free-space cutaneous haptic feedback via toroidal air-vortices

    Shtarbanov, Ali
    With recent developments in visual interface technologies, which are now capable of delivering rich and highly immersive experiences, the need has arisen to develop equally capable haptic-feedback technologies that can complement and be easily integrated with their visual counterparts to enable fully immersive, multimodal, interactive experiences. Moreover, with touchscreen devices rapidly replacing physical controls, as in the case of automobiles and industrial equipment, there has been a loss of natural haptic cues and an increased need for operators to divert their attention from the task at hand into the touchscreen just to find the locations of different controls - which...

  3. Automated histopathological analyses at scale

    Mohit, Mrinal
    Histopathology is the microscopic examination of processed human tissues to diagnose conditions like cancer, tuberculosis, anemia and myocardial infractions. The diagnostic procedure is, however, very tedious, time-consuming and prone to misinterpretation. It also requires highly trained pathologists to operate, making it unsuitable for large-scale screening in resource-constrained settings, where experts are scarce and expensive. In this thesis, we present a software system for automated screening, backed by deep learning algorithms. This cost-effective, easily-scalable solution can be operated by minimally trained health workers and would extend the reach of histopathological analyses to settings such as rural villages, mass-screening camps and mobile...

  4. Toward a Holobiont Urbanism : microbial sampling scalability through Apis mellifera

    Perez, Miguel (Miguel Angel)
    We are in constant symbiosis with the 100 trillion microbes in our gut and the complex system of bacteria around us in our environment. Within the field of metagenomics, it's clear that understanding the built environment is necessary in order to learn more about ourselves as participants in this microbial ecosystem. By understanding the cities which we inhabit in from a bacterial point of view we can begin to discern the invisible qualities of cities. I want to understand the city as a biological organism, understand its bacterial ecosystem and visualize the invisible microbial world within the built environment. I...

  5. Minimization of aberrations for the Mark IV holographic architecture using optical software modeling

    MacInnes, Andrew S
    The Mark IV holographic video display, created by Daniel Smalley in the Object-Based Media Group at the MIT Media Lab, generates a three-dimensional image by illuminating a guided wave acousto-optic modulator, upon which is written a multiplexed acoustic hologram, with red, green, and blue lasers. Despite remarkable gains attained during Mark IV's inception, the reconstructed images still possess undesirable aberrations. This work's chief aim is to mitigate these aberrations by replacing many of the current optical elements with higher-end components through the aid of optical software modeling. Modeling of the optical setup is performed with a raytracing software package called...

  6. Inward to outward

    Liu, Xin, S.M. Program in Media Arts and Sciences (Massachusetts Institute of Technology)
    This is me, my hair, my lip, my smell, the way my head moves and the body I live in. The sense of self is not fixed but continuously updates in response to the present information. When the body senses itself internally and localizes its actions, it provides the basis for a material sense of self existence. At the same time, the mind registers the sense of an agency with free will, the sense of being, the cause of voluntary action. The present self continuously becomes the past, and by the time we look into it we are in another...

  7. Gender shades : intersectional phenotypic and demographic evaluation of face datasets and gender classifiers

    Buolamwini, Joy Adowaa
    This thesis (1) characterizes the gender and skin type distribution of IJB-A, a government facial recognition benchmark, and Adience, a gender classification benchmark, (2) outlines an approach for capturing images with more diverse skin types which is then applied to develop the Pilot Parliaments Benchmark (PPB), and (3) uses PPB to assess the classification accuracy of Adience, IBM, Microsoft, and Face++ gender classifiers with respect to gender, skin type, and the intersection of skin type and gender. The datasets evaluated are overwhelming lighter skinned: 79.6% - 86.24%. IJB-A includes only 24.6% female and 4.4% darker female, and features 59.4% lighter...

  8. Spaces that perform themselves

    L'Huillier, Nicole (L'Huillier Chaparro)
    Building on the understanding of music and architecture as creators of spatial experience, this thesis presents a novel way of unfolding music's spatial qualities in the physical world. Spaces That Perform Themselves exposes an innovative response to the current relationship between sound and space: where we build static spaces to contain dynamic sounds. What if we change the static parameter of the spaces and start building dynamic spaces to contain dynamic sounds? A multi-sensory kinetic architectural system is built in order to augment our sonic perception through a cross-modal spatial choreography that combines sound, movement, light, color, and vibration. By...

  9. Explorations in computational tinkering

    Presicce, Carmelo
    In recent years, there has been a growing interest in tools and strategies to support computational thinking, emphasizing a systematic application of computational ideas to problem solving. In this thesis, I focus instead on computational tinkering, exploring tools and strategies to support playful and iterative experimentation with physical and computational materials. I propose two different ways to look at computational tinkering: bringing the playful attitude of tinkering to building with code, and integrating computation into physical tinkering activities. Through four case studies, I describe the design and facilitation of activities for children in different contexts, using a particular tool LEGO...

  10. Bikebump : collective urban design

    Sakai, Yasushi, S.M. Massachusetts Institute of Technology
    Present urban planning issues require to involve the public in the urban design process, and this slow and complicated process remains the primary domain of expert planners and consultants. Although there have been many attempts to leverage new mobile tools to engage the community. These tools support the three stages of planning 1. data collection 2. analysis and visualization three solutions. Within these tools, some gather unstructured data that is hard to convert into physical interventions. Also, some applications are not designed to encourage debate and consensus building. This study will consider how a structured integrated tool will help the...

  11. Panoptic

    Sanchez Lengeling, Thomas
    Imagine traveling to a destination and, once you are there, hearing only car horns or seeing only a green sky. This project is an augmented reality experience in which you see and hear your current city while you are in another location through an immersive helmet. The multimodal experience includes augmented sounds and images that are generated by a semantic segmentation of your visual field. The segmentation produces overlaid sonic textures and superimposed visuals, modeling a newly perceived reality. The system presents cases where it is possible to imagine another place deeply and to become accustomed to a new location...

  12. Cyborg botany : augmented plants as sensors, displays and actuators

    Sareen, Harpreet
    Plants are photosynthetic eukaryotes with a billion years of evolutionary history. While primarily sessile, they have developed distinctive abilities to adapt to the environment. They are self-powered, self-fabricating, self-regenerating and active signal networks. They carry highly advanced systems to sense and respond to the environment. We strive for such sensing and responses in our electronics; self growing or self repairing abilities in our architecture; and being sustainable at scale in general. The industrial and technological thought process has mostly been devising artificial means or replicating natural systems synthetically. However, I propose a convergent view of technological evolution with our ecology...

  13. Droplet IO : programmable droplets for human-material interaction

    Umapathi, Udayan
    In this thesis, I propose aqueous droplets as a form of programmable material that can computationally transform its physical properties. Liquid matter can undergo physical transformation through interfacial forces and surface tension. I introduce a system called DropletIO to regulate interfacial forces through a programmable electric field. The system can actuate and sense macro-scale (micro-liter to milli-liter) droplets on arbitrary planar and curved surfaces. The system can precisely move, merge, split, and change shape of droplets and thus enables a range of applications with human interactivity, information displays, parallelized programmable chemistry and dynamically tunable optics. DropletIO system uses electrowetting on...

  14. From children's play to intentions : a play analytics framework for constructionist learning apps

    Soltangheis, Mina
    Educational games and digital learning environments provide opportunities to collect fine-grained data on how learners engage with these technologies. The number of technologies targeted at literacy learning for children is increasing. However, the majority of them are structured and reward-based. Therefore, the users' behavior and data collected from them have the same limits. In this thesis, however, we assess children's engagement with a constructionist literacy learning app. The open ended nature of play in such an environment gives us the opportunity to analyze children's play not only through what they made while playing but also how they did it. This...

  15. Chemical inflation for assisted assembly

    Webb, Penelope Eugenia
    This thesis aims to utilize an output method for popup fabrication, using chemical inflation as a technique for instant, hardware-free shape change. By applying state-changing techniques as a medium for material activation, we provide a framework for a two-part assembly process, starting from the manufacturing side, whereby a structural body is given its form, through to the user side, where the form potential of a soft structure is activated and a form becomes complete. The process discussed in this thesis is similar in nature to existing chemical reaction home-activation kits, such as hand warmers or cold packs, however, with the...

  16. CityMatrix : an urban decision support system augmented by artificial intelligence

    Zhang, Yan, S.M. Program in Media Arts and Sciences (Massachusetts Institute of Technology)
    Cities are our future. Ninety percent of the world's population growth is expected to take place in cities. Not only are cities becoming bigger, they are also becoming more complex and changing even more rapidly. The decision-making process in urban design and urban planning is outdated. Currently, urban decision-making is mostly a top-down process, with community participation only in its late stages. Furthermore, many design decisions are subjective, rather than based on quantifiable performance and data. Urban simulation and artificial intelligence techniques have become more mature and accessible. However, until now these techniques have not been integrated into the urban...

  17. Towards sequencing by synthesis In Situ

    Payne, Andrew C. (Andrew Colin)
    The development of fluorescence in situ nucleic acid sequencing (FISSEQ) will permit investigators to answer scientific questions in which the spatial context of gene expression rather than just identity and abundance - must be taken into account; recent progress in biological sample engineering, including physical expansion of tissue (i.e. Expansion Microscopy), will radically empower this technology (ExSEQ). However, in situ sequencing is technically difficult to implement, requiring an investigator to be familiar with a wide variety of techniques in molecular biology, microfluidics, fluorescence microscopy, image processing, and bioinformatics, and improvements are still needed before it is widely practicable. In this...

  18. Translational design computation

    Bader, Christoph, S.M. Massachusetts Institute of Technology
    This thesis introduces, demonstrates and implements translational design computation: a theoretical approach and technical framework for mediating living and nonliving matter through design computation. I propose that computational design can act as a "language" for the enablement of design at the intersection of the material and the biological domains. I support and validate this proposition by formulating, deploying and evaluating a triad of strategies as follows: (1) Programmable Matter-utilizing computational design in combination with synthetic material systems to enable biologically inspired and informed design; (2) Programmable Templating-utilizing computational design in combination with, and at the intersection of, synthetic and biological...

  20. Minionate : The collectible card game

    Berman, Benjamin S
    Video game players experience opposing motivations to cooperate and compete in multiplayer games. The most pervasive multiplayer games today-massively multiplayer role playing and team-based competitive games-rely on a common compromise: they stratify players by their skill and in-game resources. This design choice limits a player's most meaningful forms of cooperation: participating in novel tactics and strategies, writing her own story, and being part of another player's journey towards greatness in the game. This thesis presents "Minionate," a digital collectible card game that transforms one-versus-one competitive matchups into a multiplayer experience. It introduces new mechanics that enable meaningful and asynchronous interactions...
