Box 15400, FI-00076 Aalto, Finland mikko.pohja@hut.fi Received August 1, 2009 Revised February 25, 2010 In addition to being a platform for information access, the World Wide Web is increas- ingly becoming an application platform. While web applications have several benefits compared to desktop applications, there are also some problems. With legacy HTML, for example, one cannot produce user interfaces such as those that users have become accustomed to with desktop applications. What worked for static documents is not suf- ficient for the complicated web applications of today. Several parties have addressed this problem by defining a specific UI description language. In addition, the renewal of HTML aims to enhance support for web applications. This study evaluated five XML- based UI description formats, including HTML 5, in order to determine which language is best suited for modern web application development. The study also assessed what kind of applications are suited to each format. The requirements for a Web UI descrip- tion language from the literature were revised and three use cases were defined, through which the languages are evaluated. The paper also presents the model differences of the languages. Keywords: Web User Interface Description Language, Web Application Communicated by: D. Lowe & O. Pastor 1 Introduction Commerce and communication tasks, such as the use of e-mail, are common today on the World Wide Web (WWW), as is a trend towards realizing higher interaction tasks, such as in- formation authoring.

  • Kinect Based Painter

    Kinect Based Painter

    PiccasoNect – - Kinect based Painter Introduction Kinect is a line of motion sensing input devices by Microsoft for Xbox 360 and Xbox One video game consoles and Windows PCs. Based around a webcam-style add-on peripheral, it enables users to control and interact with their console/computer without the need for a game controller, through a natural user interface using gestures and spoken commands. Kinect sensor is based on Prime-Sense technology and there are similar sensors on the market such as Asus Xtion and PrimeSense Carmine. (http://en.wikipedia.org/wiki/Kinect) Windows Presentation Foundation (or WPF) is a graphical subsystem for rendering user interfaces in Windows-based applications by Microsoft. WPF attempts to provide a consistent programming model for building applications and separates the user interface from business logic. It resembles similar XML-oriented object models, such as those implemented in XUL and SVG. (http://en.wikipedia.org/wiki/Windows_Presentation_Foundation) Overview In the project we developed a WPF application which allows the user to create a painting using his hands with minimal interactions with the mouse and keyboard. Using the Kinect, the application follows the user's hands movements, and translates them to a brush strokes. The application allows the user to select a brush from several rendering methods. Application requirements Capture user movements using Kinect sensor Paint the desired brush according to the user hands movements Enable several rendering options to choose from Option to save and send via email the finished painting Project Infrastructure The project is A WPF application, based on Microsoft Kinect SDK 1.7.

INTRODUCTION teams of people to produce large systems. This paper addresses a 1.1 Software engineering different angle of software engineering, that of development for Software engineering as a discipline is perceived as tackling re-use and portability. We consider how an essential part of computing in-the-large. It elevates tools and techniques from the most software products – the user interface – can be successfully level of a craft, to where they can be efficiently and reproducibly engineered so that it can be portable across multiple platforms harnessed for the successful completion of large projects. and on multiple devices. Our research has identified the structure of the problem domain, and we have filled in some of Thirty years ago in 1975, Fred Brooks introduced us to the the answers. We investigate promising solutions from the mythical man month of software development [Brooks 1975] model-driven frameworks of the 1990s, to modern XML-based and followed this with the “no silver bullet” paper, in which he specification notations (Views, XUL, XIML, XAML), multi- talked about software engineering as being a process of building platform toolkits (Qt and Gtk), and our new work, Mirrors software with “specifications, assembly of components, and which pioneers reflective libraries.
