In our research we apply the principle of separation of concerns onto User Interfaces. The goal is to get a clean separation in the source code between code responsible for UI logic and code responsible for the application logic. Since both are tightly coupled (i.e. the application logic needs to interact closely with UI logic and vice versa), this results in code entanglement which reduces the...

Modeling Steel Plate Shear Wall (SPSW) behavior can be computationally demanding. This is especially true when high-fidelity modeling carried out via shell or 3D solid elements. It has been shown that SPSW captured with adequate accuracy through the strip method nonlinear truss elements idealization. The widely accepted and reliable analysis platform, OpenSees, requires text-based input (.tcl) ...

A common problem faced by technology projects is that while every effort is made to deliver at the highest quality, and ensuring well constructed business specifications, the outcome falls short of user expectations, rendering a system difficult to use, thereby negatively impacting adoption by the user. This paper highlights the need to involve the user at an early stage in the development proc...

User interface (UI) plasticity denotes UI adaptation to the context of use (user, platform, physical and social environment) while preserving usability. Our approach to this problem is to bring together MDE (Model Driven Engineering) and SOA (Service Oriented Approach) within a unified framework that covers both the development stage and the runtime phase of plastic UI’s. In particular, an inte...

The intuitiveness of tangible user interface (TUI) is not only for its operator. It is quite possible that this type of user interface (UI) can also have an effect on the experience and learning of observers who are just watching the operator using it. To understand the possible effect of TUI, the present study focused on the mu rhythm suppression in the sensorimotor area reflecting execution a...

In this article, model-based design and synthesis of reactive user interfaces is presented as a particular application of Computer-Automated Multi-Paradigm Modelling (CAMPaM). Multi-paradigm modelling acknowledges the need to model at different levels of abstraction, using appropriate formalisms. It also gives transformations first-class model status. In the CAMPaM UI development process, a cla...

In recent years, the use of various information terminals such as smartphones and personal computers have become widespread, situations where are used diverse. With increased opportunities to outdoors during travel, some users been using peep-prevention filters, or software with an equivalent function, on their displays, in order protect privacy. However, filters problems regards effectiveness,...

The navigation structure of Web sites can be regarded as metadata that can be used for interesting applications in User Interface (UI) design and Human-Computer Interaction (HCI), as well as for Information Retrieval (IR) tasks. However, there currently is no established format for site metadata, which makes it hard for Web sites to publish their structure in a machine-readable way, which could...

The number of mobile applications has increased drastically in the past few years. Some applications are superior to the others in terms of user-perceived quality. User-perceived quality can be defined as the user’s opinion of a product. For mobile applications, it can be quantified by the number of downloads and ratings. Earlier studies suggested that user interface (UI) barriers (i.e., input ...

The growth of user mobility has created new user needs. Cellular phones, personal assistants and modern communication means are now required for all user tasks. Users want services that are specifically mobile, but they also want to work with and have access to the same applications on their mobile devices as they have at their work place. The mobile system must thus be adapted according to the...
