The Ten Commandments of Prototyping

Rapid prototyping is seen by many as the solution to numerous difficulties facing today's systems development managers. Yet there is no such thing as a single rapid prototyping model. Prototyping tools and techniques are quite diverse, and project failures attributed to prototyping are not uncommon. This column offers a set of guidelines to those managers who wish to successfully exercise rapid prototyping techniques.     

Ten Commandments of Internet Law revisited: basic principles for Internet Lawyers

Internet Lawyers are specialized in issues on the intersection of Law and the Internet. The connection between knowledge of the law and understanding of the Internet is one of constant interaction. Scholars can approach Internet Law basically from two angles. First, the classic legal approach is to start with the legal norm, and see whether Internet phenomena are covered by existing norms, either applied straightforwardly or after interpretation. If no existing norm can be applied, the situation can be left unregulated or if desirable new norms can be designed. Second, the Internet can be taken as a starting point, so to think about possible norms without considering the existing normative framework. This approach can lead to new, refreshing insights. Both approaches have their merits. This paper introduces a set of principles for all Internet Lawyers a set of principles, called the Ten Commandments of Internet Law. Also, an empirical evaluation performed by a group of 43 Internet Law students used to improve the initial set is discussed. The set proposed in the end is not, however, considered to be the definite collection of principles for Internet lawyers. Rather the Ten Commandments should be considered a dynamic set in which commandments can be refined, added or deleted.     

The Problematics of Human Prototyping and Animation

Several ideas and experiments are presented for the creation and realistic animation of three-dimensional scenes involving human beings conscious of their environment. The various approaches should allow the intelligent creation of human beings using prototypes and generate their animation based on mechanics, artificial intelligence and robotics. This paper discusses the problems involved in three major steps of the simulation of human beings: the creation of the human shapes, the motion of the human skeleton, and the deformation of the surfaces. Several examples are presented illustrating positional constraints, dynamics, behavioural animation and finite element theory.

Virtual Video Prototyping

Computing power is an integrated part of our physical environment, and since our physical environment is three-dimensional, the virtual studio technology, with its unique potential for visualizing digital 3D objects and environments along with physical objects, offers an obvious path to pursue in order to envision future usage scenarios in the domain of pervasive computing.We label the work method virtual video prototyping, which grew out of a number of information systems design techniques along with approaches to visualization in the field of architecture and set design.We present a collection of virtual video prototyping cases and use them as the platform for a discussion, which pinpoint advantages and disadvantages of working with virtual video prototyping as a tool for communication, experimentation and reflection in the design process. Based on more than ten cases we have made the observations that virtual video prototypes 1) are a powerful medium of communication in development teams and for communication with industry partners and potential investors, 2) support both testing and generating ideas 3) are particular suited for addressing spatial issues and new ways of interacting. In addition practical use of virtual video prototypes has indicated the need to take into account some critical issues including a) production resources, b) hand-on experience, and c) the seductive power of virtual video prototypes.

Prototyping networked embedded systems

Sophisticated consumer devices that support multimedia-personal digital assistants, network computers, and mobile communication devices-pose challenges for embedded systems designers. The low-cost, consumer-oriented, fast time-to-market mentality that dominates embedded system design today forces design teams to use hardware-software codesign to cope with growing design complexities. New codesign methodologies and tools must support a key characteristic of next-generation embedded systems: the capability to communicate over networks and adapt to different operating environments. The paper discusses two emerging classes of embedded systems: multifunction systems and multimode systems

Prototyping synchronous group applications

Cooperative team-based activities are changing the nature of work. Current frameworks provide the necessary base communication and coordination tools but require application designers to handle low-level details such as defining a communication protocol. They also provide limited support for prototyping such applications and experimenting with alternative designs. We introduce a sharing style called strong sharing. Its implementation in Object World insulates application designer from low-level communication details. CoSARA, a system built on Object World, lets application designers prototype synchronous group applications by graphically specifying the multiuser interactions. After we describe strong sharing, we describe Object World and how it facilitates building synchronous group applications. Then we describe the CoSARA design methodology for prototyping synchronous group applications and show how we used it to build a multiuser block diagram editor
