The communication between user and software is a basic stage in any Interaction System project. In interactive systems, this communication is established by the means of a graphical interface, whose objective is to supply a visual representation of the main entities and functions present in the Virtual Environment. New ways of interacting in computational systems have been minimizing the gap in the relationship between man and computer, and therefore enhancing its usability. The objective of this paper, therefore, is to present a proposal for a non-conventional user interface library called ARISupport, which supplies ARToolKit applications developers with an opportunity to create simple GUI interfaces, and provides some of the functionality used in Augmented Reality systems. © Springer-Verlag Berlin Heidelberg 2005.

This paper explores the notion of marrying two technologies: raster-scan computer animation and optical video discs. Animated sequences, generated at non real-time rates, then transfered to video disc, can be recalled under user control at real-time rates. Highly detailed animation may be combined with other media in interactive systems. Such systems inherently offer a greater degree of flexibility to the animator. The implementation of one such system is discussed in detail.; by Walter Bender.; Thesis (M.S.V.S.)--Massachusetts Institute of Technology, Dept. of Architecture, 1980.; MICROFICHE COPY AVAILABLE IN ARCHIVES AND ROTCH.

Approved for public release, distribution is unlimited.; The Department of Defense relies on modeling and simulation for a variety of purposes, including joint exercise training, developing and evaluating doctrine and tactics, and studying weapon system effectiveness. Advances in technology have made the achievement of technically and visually accurate simulations possible, but little has been done to present realistic scenarios while supporting user interaction. This dissertation describes a multi-agent interactive simulation engine for generating interactive scenarios or stories. A general-purpose multi-agent system simulation architecture, called a Connector-based Multi-Agent System (CMAS) is developed and presented, along with a software agent communication and coordination mechanism. In this architecture, stories are generated through discovery as a by-product of agent interactions, rather than being fixed in advance. The ensuing story adapts to the user's interventions and is closely aligned to the goals of the agents. The multi-agent system design of the story engine has resulted in a data-driven simulation engine, which is domain independent and highly scalable. The story engine is fielded as the underlying simulation engine behind the U.S. Army's America's Army: Soldiers project. The instantiation of the story engine as it applies to Soldiers is presented. As a component of Soldiers...

Quantum finite automata have been studied intensively since their introduction in late 1990s as a natural model of a quantum computer with finite-dimensional quantum memory space. This paper seeks their direct application to interactive proof systems in which a mighty quantum prover communicates with a quantum-automaton verifier through a common communication cell. Our quantum interactive proof systems are juxtaposed to Dwork-Stockmeyer's classical interactive proof systems whose verifiers are two-way probabilistic automata. We demonstrate strengths and weaknesses of our systems and further study how various restrictions on the behaviors of quantum-automaton verifiers affect the power of quantum interactive proof systems.; Comment: This is an extended version of the conference paper in the Proceedings of the 9th International Conference on Implementation and Application of Automata, Lecture Notes in Computer Science, Springer-Verlag, Kingston, Canada, July 22-24, 2004

In this paper we consider quantum interactive proof systems, i.e., interactive proof systems in which the prover and verifier may perform quantum computations and exchange quantum messages. It is proved that every language in PSPACE has a quantum interactive proof system that requires only two rounds of communication between the prover and verifier, while having exponentially small (one-sided) probability of error. It follows that quantum interactive proof systems are strictly more powerful than classical interactive proof systems in the constant-round case unless the polynomial time hierarchy collapses to the second level.; Comment: 13 pages

This paper gives the first formal treatment of a quantum analogue of multi-prover interactive proof systems. It is proved that the class of languages having quantum multi-prover interactive proof systems is necessarily contained in NEXP, under the assumption that provers are allowed to share at most polynomially many prior-entangled qubits. This implies that, in particular, if provers do not share any prior entanglement with each other, the class of languages having quantum multi-prover interactive proof systems is equal to NEXP. Related to these, it is shown that, in the case a prover does not have his private qubits, the class of languages having quantum single-prover interactive proof systems is also equal to NEXP.; Comment: LaTeX2e, 19 pages, 2 figures, title changed, some of the sections are fully revised, journal version in Journal of Computer and System Sciences

Interactive displays are driven by natural interaction with the user, necessitating a computer system that recognizes body gestures and facial expressions. User inputs are not easily or reliably recognized for a satisfying user experience, as the complexities of human communication are difficult to interpret in real-time. Recognizing facial expressions in particular is a problem that requires high-accuracy and efficiency for stable interaction environments. The recent availability of the Kinect, a low cost, low resolution sensor that supplies simultaneous color and depth images, provides a breakthrough opportunity to enhance the interactive capabilities of displays and overall user experience. This new RGBD (RGB + depth) sensor generates an additional channel of depth information that can be used to improve the performance of existing state of the art technology and develop new techniques. The Active Shape Model (ASM) is a well-known deformable model that has been extensively studied for facial feature point placement. Previous shape model techniques have applied 3D reconstruction techniques using multiple cameras or other statistical methods for producing 3D information from 2D color images. These methods showed improved results compared to using only color data...

Providing certain Solid Modeling software systems with Computer-Aided Design Drafting facilities allows these systems to produce industry acceptable engineering drawing displays. A method is put forth to provide these facilities through the design and implemention of a two-dimensional interactive graphics package that interfaces with these systems. This allows other graphical and textual elements to be added to displays produced by the Solid Modeling systems.

What do young adults (age 12-18) think entertainment consists of? Is it movies, television, computer games, video tapes, multi-media products? What about books, are books considered entertainment? Because interactive multi-media can incorporate text, sound, music, animation, Quicktime movies and allows user interaction, books have become a neglected part of the entertainment market. Even though multi-media can be highly interactive, reading books is highly interactive too. The readers must use their imagination to construct the many images, sounds, and moods of the book. There is the concern that people really don't know how to read. A vast majority of these multi-media games are aimed at boys, using the male as the main character of the game. Playing video games at an early age provides an entry to developing computer skills needed in the workforce. Girls have become alienated by not having games aimed at them. Using an active female character in the game instead of passive female roles would be one way to encourage girls to play with computers. Since many games rely on sound or have voice overs, it has excluded the deaf population from computer technology and entertainment as well. The purpose of this project is to create an interactive multi-media game that uses a book as part of the game. To play this game...

"Human abilities should be amplified, not impeded, by using computers" -- Mark T. Maybury In an attempt to evaluate the effectiveness of various screen interfaces utilized in interactive multimedia, an interactive thesis project was prepared to conduct tests. Walt Disney anima tion was chosen for the theme. The project was duplicated so that there were three identical copies - each representing different styles of interface navigation, button feedback, and "Help" systems. The multimedia projects were displayed on neighboring computers simul taneously so that a person could move directly from one to another with ease and no disrup tions. Each person was given an evaluation sheet for each multimedia project and completed them one at a time. The sheets were then tallied and analyzed for signs of favoritism toward any style in particular. "Multimedia interfaces are computer interfaces that communicate with users using multiple media (e.g., language, graphics, animation, video, non-speech audio), sometimes using multiple modes together such as written text together with spoken language" (Maybury, 1993). The three styles of interface navigation that the author tested are as follows; a rectangular navigation palette containing all necessary buttons...

The purpose of this thesis is to explore the possibilities of computer graphics applied to information delivery systems. Devising a car information system, I will produce an interactive application that will provide facts about new automobiles. The project will combine computer generated images, acquired images, sound, video, etc.- all controlled by the user. The main goal is to develop a proper user interface which allows any person to utilize the application and walk away with adequate knowledge about the automobile. In this thesis project, I attempted to model a computer kiosk which introduces Acura automobiles. It is a promotional tool. The process combined an interactive design technique with the use of Macintosh application software. The user interface design is accomplished by taking advantage of the multimedia capabilities of the computer (i.e. graphics applications, sound and video applications, data storage, playback systems, etc.).

Designing and implementing a user interface (UI) is among the costliest tasks in developing interactive software systems. As a result, much work is being done in the area of User Interface Management Systems (UIMSs). These systems make it easier to develop complex user interfaces more quickly because specification of user interface dialogs is at a closer level to that at which UI designers express themselves. This paper describes the generic structure of a UIMS and several examples of previous work in the field. Many UIMSs are implemented as explicit state machines that use conventional state transition diagrams or state metaphors to specify dialogs. The rest of this paper describes the design and implementation of Statemaster, an event-driven UIMS based on statecharts. Statecharts are a hierarchical extension of state diagrams well suited for describing complex reactive systems with a compact, visual notation. These diagrams are directly implemented by Statemaster with an object-oriented architecture in the C++ programming language. Statemaster has been found to be general enough to implement a wide range of user interface dialogs. It can be used as a prototyping tool for UI development, and it is efficient enough to be used as the final...
