Canny, Chair With an estimated 4.6 billion units in use, mobile phones have already become the most popular computing device in human history. Their portability and communication capabil- ities may revolutionize how people do their daily work and interact with other people in ways PCs have done during the past 30 years. Despite decades of experiences in creating modern WIMP (windows, icons, mouse, pointer) interfaces, our knowledge in building ef- fective mobile interfaces is still limited, especially for emerging interaction modalities that are only available on mobile devices. This dissertation explores how emerging sensors on a mobile phone, such as the built-in camera, the microphone, the touch sensor and the GPS module can be leveraged to make everyday interactions easier and more efficient.

  • A Model of Inheritance for Declarative Visual Programming Languages
    An Abstract Of The Dissertation Of Rebecca Djang for the degree of Doctor of Philosophy in Computer Science presented on December 17, 1998. Title: Similarity Inheritance: A Model of Inheritance for Declarative Visual Programming Languages. Abstract approved: Margaret M. Burnett Declarative visual programming languages (VPLs), including spreadsheets, make up a large portion of both research and commercial VPLs. Spreadsheets in particular enjoy a wide audience, including end users. Unfortunately, spreadsheets and most other declarative VPLs still suffer from some of the problems that have been solved in other languages, such as ad-hoc (cut-and-paste) reuse of code which has been remedied in object-oriented languages, for example, through the code-reuse mechanism of inheritance. We believe spreadsheets and other declarative VPLs can benefit from the addition of an inheritance-like mechanism for fine-grained code reuse. This dissertation first examines the opportunities for supporting reuse inherent in declarative VPLs, and then introduces similarity inheritance and describes a prototype of this model in the research spreadsheet language Forms/3. Similarity inheritance is very flexible, allowing multiple granularities of code sharing and even mutual inheritance; it includes explicit representations of inherited code and all sharing relationships, and it subsumes the current spreadsheet mechanisms for formula propagation, providing a gradual migration from simple formula reuse to more sophisticated uses of inheritance among objects. Since the inheritance model separates inheritance from types, we investigate what notion of types is appropriate to support reuse of functions on different types (operation polymorphism). Because it is important to us that immediate feedback, which is characteristic of many VPLs, be preserved, including feedback with respect to type errors, we introduce a model of types suitable for static type inference in the presence of operation polymorphism with similarity inheritance.

    Abstract Over the last decade, researchers have been interested in personalised recommender sys- tems as they have detected the many profitable applications they have. As a direct effect many algorithms and different techniques have been developed, some of them combining user and item categorisation techniques. The purpose of this work is to bring the capabilities of such sys- tems to the context of museums and art galleries and combine them with advanced visualisation techniques. This will be done in order to help the users to explore a large dataset of European artworks from the 11th until the 19th century while taking advantage of a recommendation engine that will help them finding interesting artworks rapidly. To pursue the aforementioned goals, an existing application that already contains such advanced visualisation techniques and the dataset has been enhanced with recommendation capabilities. The recommendations are based on semantic user profiling techniques extracted unobtrusively from users. Using semantic user profiling to provide recommendations enables the possibility to have a hybrid recommendation algorithm with content-based and collaborative features. The rec- ommendation algorithm extracts the preferences from users through their interactions with the system and uses them to find related content that might be interesting for the user. An offline experiment has been conducted in order to assess the relative accuracy of the recommendations and the user categorisation based on semantic user profiling. The offline experiment reveals the advantages of combining such techniques and shows promise on a theoretical level on how to bring recommendations in such a restricted and relatively scarcely explored environment like the applications for museums and art galleries.

  • CS 91.540 — Visual Analytics - Spring 2010
    CS 91.540 — Visual Analytics - Spring 2010 Description Whether the cause is an epidemic, natural disaster or an act of terrorism, accurate prediction of risks, timing, and consequences of destructive events can prevent loss of life and damage to property and natural resources. Whether one is looking for a genetic marker, a trend in the stock market, patterns in educational settings, quality of life indicators, accurate analysis can help the discovery process, provide insights, and identify and measure ambiguities and uncertainties. Visual analytics is the use of information and communication technologies designed to aid analysts in a variety of fields from health, manufacturing, security, education, finance, scientific and social science research, and others, deal with massive, dynamic sets of structured (spreadsheets, databases) and unstructured data (text, web pages, video), and often conflicting data. Analysts use these technologies to provide timely, defensible, and understandable assessments and to communicate these effectively for action to both the public and decision-makers. The overall goal is to detect the expected and discover the unexpected. What you will get out of the course A student who successfully fulfills the course requirements will have demonstrated an understanding of the fundamentals of visual analytics and its applications, an understanding of the analytical reasoning process, an understanding of cognition, perception, and designing for human users, an ability to design, build, and evaluate suitable visual representations to a real-world dataset for decision makers or the public. The course The course will discuss and combine principles from cognitive science, information visualization, geospatial information systems, machine-based reasoning and learning, and data mining.
