Software Design and Media Design - tools to designMobile and Sensory Interfaces and Interactive EnvironmentsGeert de HaanCommunication, Media and Information TechnologySection Media Technology / Human Centered ICTRotterdam University of Applied SciencesP.O.Box 25035, 3001 HA, RotterdamThe Netherlandsg.de.haan@hr.nlABSTRACTThis  paper  discusses  ETAG,  a  formal  model  for  design representation, and ETAG-based design, a method for user interface  design,  and  the  two  principal  facilities  they provide  to  accommodate  different  types  of  users  in  the design  of  user  interfaces.  The  paper  starts  with  an introduction  of  ETAG  as  a  design  representation.  This  is followed by a description of ETAG-based design and using the  notation  to  represent  relevant  aspects  of  the  work context.    Next,    we    discuss    the    differences    between computer  software  design  and  media  product  design, concluding  that  media  design  is  a  much  more  flexible, iterative  process  and  prototyping-based  process  in  which adaptation  of  the  design  of  mobile  applications  extends into    the    maintenance    phase.    To    cover    further developments towards  focussing  on user needs and wishes by  means  of  co-design  practices,  and  to  cover  for ubiquitous  computing  and  interaction  with  sensors  and interactive  environments,  we  propose  to  use  sensory  labs and  to  create  living  labs  to move  the  usability  lab into the real world

Provision of personalized recommendations to users requires accurate modeling of their interests and needs. This work proposes a general framework and specific methodologies for enhancing the accuracy of user modeling in recommender systems by importing and integrating data collected by other recommender systems. Such a process is defined as user models mediation. The work discusses the details of such a generic user modeling mediation framework. It provides a generic user modeling data representation model, demonstrates its compatibility with existing recommendation techniques, and discusses the general steps of the mediation. Specifically, four major types of mediation are presented: cross-user, cross-item, cross-context, and cross-representation. Finally, the work reports the application of the mediation framework and illustrates it with practical mediation scenarios. Evaluations of these scenarios demonstrate the potential benefits of user modeling data mediation, as in certain conditions it allows improving the quality of the recommendations provided to the users.

The OpenPhone project aims to design an Interactive Voice Response (IVR) health information system that enables people who are caregivers for HIV/AIDS infected children to access relevant information by using a telephone in their native language of Setswana in Botswana. The system lowers accessibility barriers since it is accessible to illiterate users and the community of the blind. The design utilizes usability engineering methodology in order to ascertain that the end product is usable, efficient, effective and satisfactory to the targeted users who are predominantly females, ranging from semi-literate to illiterate adults but nevertheless numerically literate. The paper describes the methodologies that were used to obtain information from the target user population. Based on the information gathered, we are now able to begin the initial design of the OpenPhone system.

Presently, mobile handheld device has successfully replaced traditional telephone to become the most popular wireless communication tools. Mobile Short Message Service (SMS) and Multimedia Message Service (MMS) fulfill almost all the user requirements as an effective communication and information delivering service. Since SMS/MMS become so popular on daily communication, there is a demand to communicate or exchange confidential information in a secure environment. Public Key Infrastructure (PKI) is a proven solution, which using pairing of key, for secure communication encryption. In this paper, m–PKI is introduced to provide PKI encryption to the mobile SMS and MMS. This new approach allows the end-user to send private and classified message via SMS. The key pair generation and distribution are performed by the Certificate Authority (CA). The size of the key pair are studied and decided by the tradeoff between performance and security.

Today although a contemporary house or apartment is built with new materials according to technology and regulations to provide a satisfactory microclimate within the building, it is difficult to say they are successful comparing with a house that is constructed with traditional methods and materials even built by a non-architect. In this paper microclimatic elements of traditional Diyarbakýr houses are

This paper describes key concepts of composable FORCEnet, which is the US Navy's operational construct architectural framework for naval warfare in the information age. It describes the concepts and architecture, in several categories: 1) systems and general software engineering; 2) networks ; 3) intelligent software; and 4) network security. The engineering approach to implement FORCEnet is an example of rapid prototyping in which the requirements of the users reviewed periodically and frequently with considerable user input. This method, which captures and implement changes in user requirements, strongly supports the development of relevant and useful systems with up-to-date technology that will be responsive to the users' rapidly changing needs.

This paper reports on a case study of using rapid prototyping to develop a serious game about crime prevention. Five small-scale formative evaluations (with a total of 17 participants) were used to guide the collect user requirements and formative feedback. Early formative results are positive and provided early signals on what needs to be changed in the game design and

The main advantages of our suggested wireless monitoring network are the ability to monitor any required quantity, the usage of an efficient programming environment to allow all features of monitoring, controlling, and data processing to be implemented, the ability to extend the number of monitored patients, and the ability to transfer measurement data over wired or wireless channels. In addition to all of the above mentioned features, the system is implemented with components which achieve the minimum costs without scarifying accuracy. The use of low cost wireless communication and internet network facilities makes our suggested monitoring system reliable for all capital projects with minimum costs and ensures upgradability to adapt additional wide user requirements.

As modern software-based systems and applications gain in versatility and functionality, the ability to manage inconsistent resources and service disparate user requirements becomes increasingly imperative. Furthermore, as systems increase in complexity, rectification of system faults and recovery from malicious attacks become more difficult, labor-intensive, expensive, and error-prone. These factors have actuated research dealing with the concept of self-healing systems. Self-healing systems attempt to “heal” themselves in the sense of ...

We report on the application of the use-case modeling technique to identify and specify the user requirements of the MammoGrid project in an incremental and controlled iterative approach. Modeling has been carried out in close collaboration with clinicians and radiologists with no prior experience of use cases. The study reveals the advantages and limitations of applying this technique to requirements specification in the domains of breast cancer screening and mammography research, with implications for medical imaging more generally. In addition, this research has shown a return on investment in use-case modeling in shorter gaps between phases of the requirements engineering process. The qualitative result of this analysis leads us to propose that a use-case modeling approach may result in reducing the cycle of the requirements engineering process for medical imaging.
