In this paper we describe a Python- and Tkinter-based visual-programming environment called ViPEr. This tool enables non-programmers to build computational and visualization networks interactively. Computational nodes can be placed onto a canvas and their input and output ports can be connected using the mouse. The connections between the nodes define a directed graph that will be used to propagate data and trigger the execution of nodes that have new input data. ViPEr is, in appearance, similar to programs such as AVS [Upson et al. 89] from Advanced Visual Simulations Inc, or OpenDX [DX 93] from IBM, but presents some fundamental differences which will be pointed out throughout this paper. Several examples of applications will be used to illustrate ViPEr’s design and current range of capabilities.

We present a vision system for the 3-D model- based tracking of unconstrained human movement. Using image sequences acquired simultaneously from multiple views, we recover the 3-D body pose at each time instant without the use of markers. The pose- recovery problem is formulated as a search problem and entails finding the pose parameters of a graphical human model whose synthesized appearance is most similar to the actual appearance of the real human in the multi-view images. The models used for this purpose are acquired from the images. We use a decomposition approach and a best-first technique to search through the high dimensional pose parameter space. A robust variant of chamfer matching is used as a fast similarity measure between synthesized and real edge images.

Web services, an emerging paradigm for architecting and implementing business collaborations within and across organizational boundaries, are currently of interest to both software vendors and scientists. In this paradigm, the functionality provided by business applications is encapsulated within web services: software components described at a semantic level, which can be invoked by application programs or by other services through a stack of Internet standards including HTTP, XML, SOAP, WSDL and UDDI [3,18]. Once deployed, web services provided by various organizations can be inter-connected in order to implement business collaborations, leading to composite web services.

Google Earth is a popular and widely used geographical browser. It is a standalone application that enables spatial data from a variety of sources to be displayed, explored and visually compared. Google Earth has the following important characteristics:
• Free
• Easy-to-use and intuitive user interface. Data are displayed on an interactive globe that can be rotated and zoomed to visually explore data in different regions of the world and at different spatial resolutions.

An emerging trend in Social Networking sites and Web portals is the opening up of their APIs to external application develop- ers. For example, the Facebook Platform, Google Gadgets and Yahoo! Widgets allow developers to design their own applications, which can then can be integrated with the platform and shared with other users. However, current APIs are targeted towards develop- ers with programming expertise and database knowledge; they are not accessible to a large class of users who do not have a programming/database background, but would nevertheless like to create new applications. To address this need, we have developed the AppForge system, which provides a WYSIWYG application development platform. Users can graphically specify the components of webpages inside a Web browser, and the corresponding database schema and application logic will be automatically generated on the fly by the system.

The Goal: Optimizing the Home Theater Control GUI For Useability GUI = Graphical User Interface
Touch screens are “cool”. Fancy color graphics, slick looking button layouts and elaborate menu structures are multiplying everywhere you look. Fancy doesn’t mean good. Remember the key reason your customers are paying you for a professional installation:
