We describe a software interface for drawing in three dimensions using a game pad. The software runs in a walk-in, virtual-reality theatre and has been designed for walk-up usability for a science museum. Usability aspects of the interface are discussed including the mapping of the thumb-joystick controllers and movements of the cursor in three dimensions.

Testing and verification of the interface between software components are particularly important due to the large number of complex interactions, which requires the traditional modeling languages to overcome the existing shortcomings in the aspects of temporal information description and software testing input controlling. This paper presents the real-time extended interface automata (RTEIA) wh...

Managing the organizational and software complexity of a comprehensive open source digital library system presents a significant challenge. The challenge becomes even more imposing when the interface is available in different languages, for enhancements to the software and changes to the interface must be faithfully reflected in each language version. This paper describes the solution adopted b...

Most software development approaches and curricular guidelines seem to ignore the fact that in many software systems the user interface is a decisive factor for product quality. As a result, it is often designed rather independently of the system’s functionality. Chances are then that it does not get the attention it deserves. In the approach to software development we sketch, the design of the...

Network interfaces that contain a programmable processor offer much flexibility, which so far has mainly been used to optimize message passing libraries. We show that high performance gains can be achieved by implementing support for application-specific shared data structures on the network interface processors. As a case study, we have implemented shared transposition tables on a Myrinet netw...

Software reusability is an essential characteristic of Component-Based Software (CBS). The component reusability is an important assess for the effective reuse of components in CBS. The attributes of reusability proposed by various researchers are studied and four of them are identified as potential factors affecting reusability. This paper proposes metric for reusability estimation of black-bo...

Majority of agile projects currently involve interactive user interface designs, which can only be possible by following UCD in agile software model. But the integration of UCD is not clear in the current agile models. Both Agile models and UCD have iterative nature but agile models focus on coding and development of software; whereas, UCD focuses on user interface of the software. Similarly, b...

Computer software to calculate electron mobility with respect to different scattering mechanism has been developed. This software is adopted completely Graphical User Interface (GUI) technique and its interface has been designed by Microsoft Visual basic 6.0. As a case study the electron mobility of n-GaN was performed using this software. The behavior of the mobility for nGaN due to elastic sc...
