A category of user interface design patterns offers several design solutions and techniques. To solve one design problem, novice designers may have a difficult time in deciding which design pattern they should use. This study examined user satisfaction toward six user interface design patterns of search box and autocomplete: 1) a simple search box, 2) a search box with a dropdown menu, 3) a search...
In the last decade, on-board computers were continuously substituted by sophisticated in-car-infotainment systems due to the ever increasing demand for mobile services and entertainment features. As a consequence, the automotive user interfaces became more complex and a driver is now faced with the time and attention-consuming task of traversing a menu structure in order to execute a desired functionality...
Most of the systems for generating taste sensations are based on blending different chemicals appropriately, and there are less proven approaches to stimulate the sense of taste digitally. In this paper, a method to digitally stimulate the sense of taste is introduced and demonstrated based on electrical and thermal stimulation on human tongue. Thus, two digital control systems are presented to control...
The number of files stored in a personal computer is increasing very quickly, so it is difficult for users to find the information they want. One desktop search engine named SoDesktop is proposed in this paper, which is composed of four modules including Data crawler, Task scheduler, Data indexer and Data searcher. The implementations of these four modules are described in details, and the implementation...
Many recent studies have shown that educational games are effective tools for learning. Nevertheless, it is hard to find any practical guidelines for the creation of such games. The goal of this paper is to develop such guidelines for the creation of educational adventure games.
Data integration is to provide a uniform access to multiple heterogeneous information sources available by using unified global schema. Data integration system allows users to perceive the entire collection as a single source, query it transparently, and receive a single and unambiguous answer. Ministry Of Interior (MOI) — Egypt has many different data sources, which queried by MOI administrators...
Engaging students in active learning is an important challenge in today's classrooms. The proposal presented in this paper aims to take advantage of the benefits offered by new technologies in order to increase creativity and expressiveness in educational environments. In order to achieve this, we have designed and developed a system that allows the use of creative learning techniques such as Brainstorming...
This study investigated into the effects of the "Advanced search" feature of three digital libraries on users' search performance and search efforts. Three operational digital libraries, i.e., the ACM digital library, the IEEE Computer Society digital library, and the IEEE Xplore digital library, were used in this study. Thirty-five students participated in an experiment and completed the...
Many large enterprises are wasting vast amounts of electricity due to computers that are powered-up yet unused for considerable periods of time. It is unfortunate that although the facilities to power management are already available, many administrators are reluctant to adopt power saving features. This paper first highlights the scale of electricity wastage and goes on to consider the issues associated...
Design and development for computer game have been started more than four decades ago with first computer game production that named Spacewar. At that time, such game only used to throw single-handedly. However, nowadays, digital game competition can be shared individual leisure with routine activity. Computer game suitability influenced a lot by computer design itself. A study related to basic design...
Recently, immense multimedia information is exchanged on the Internet, where 3DCG, video, image, sound, and text are involved in various circumstances with different terminal devices, networks, and users with different knowledge and competence on using computers. This fact may easily lead to so called edigital divide' unless any special support is given to the users with few knowledge. We have already...

This paper presents two tangible programming tools, which are designed to make programming concepts more accessible to novice programmers of all ages. Our design approach consists of two tangible environments with different features. The first system programs a virtual butterfly in a maze and the second is dedicated to the programming of a Lego NXT robot. Both approaches are presented and their function...
With the increasing use of 3D displays and input devices we need to be sure that when 3D worlds are created that their users can easily learn how to operate within these 3D worlds. To do this we can provide the user with a contextal interaction support within the environment. Within virtual worlds where you are free to move around and especially when you are immersed, trying to refer to a manual to...
Usability can be attended from early phases by incorporating task and user analysis with framework's components. This fact benefits also the development of mobile applications, obtaining more usable systems tailored to the needs of a specific user with unique characteristics.
E-commerce system design based on B / S structure gives us a lot of convenience, but it also brings security risks: the password is compromised or decoded. This paper presents a solution for rural e-commerce platform based on smart client security technology, it can not only increase the security of the system, but also has the characteristics of flexible operation. If a new type of rural e-commerce...
In recent years, E-learning has been in a continuous development, due to the fact that it eases the process of teaching, evaluation and selfevaluation, offering schedulling flexibility and a tool support. E-learning makes learning content available even in remote locations, eliminating the need to travel to the place where the content is delivered. Nevertheless, the current E-learning platforms have...
This paper describes the concept of a dynamic blocks platform, called ARBlocks, based on projective augmented reality and tangible user interfaces aiming educational activities. In it, the information is displayed by projectors, that exhibit the content only on the blocks using a projector calibration technique and the blocks are tracked through a frame marker. Despite the platform is still under...
As the vision of ubiquitous computing becomes reality, there is a possibility for user interfaces that follow the user through the physical world by jumping between local display devices. This paper presents previous attempts at this functionality and identifies their limitations. Justified by these limitations, we then present our novel method that uses new features of web-based technology. This...
