This paper presents the conceptual and architectural design of a multilayered framework aiming to provide a two handed gesture based visual interactive 3D object oriented environment for software development. We argue that this is a viable, intuitive and attractive approach for software development facilitating natural human computer interaction, thus supporting tasks related to software development...
Ranking of fuzzy numbers is an important procedure for many applications in fuzzy theory, in particular, decision-making. In this paper, we propose a new method for ranking fuzzy numbers based on Dice set theoretic index. The Hurwicz criterion which considers all types of decision makers' perspective is employed in aggregating the fuzzy total evidences. The properties of the proposed method are also...
Advertising on the Internet is a key factor for the success of several businesses nowadays. The Internet has evolved to a point where it has become possible to develop a business model completely based on Web advertising, which is important for the consolidation of such a model and the continuity of the Internet itself. However, it is often observed that some content publishers are dishonest and employ...
There are many arguments for and against the use of autonomous-agents in intelligent environments. Some researchers maintain that it is of utmost importance to give complete control to users, and hence greatly restrict autonomy of agents, whereas, others believe that is it preferable to increase user convenience by allowing agents to operate autonomously on the user's behalf. While both of these approaches...
There are millions of people that regularly play Go in many countries around the world. Played by two players, Black and White, the stones of their colors are placed consecutively on an empty intersection of a square grid. In order to support beginners of Go to enjoy and concentrate on the game, this paper proposes a fuzzy markup language (FML)-based emotional expression system and applies it to computer...
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...
This paper introduces Avatar CAPTCHA, an image based approach to distinguish human users from computer programs (bots). The proposed CAPTCHA asks users to identify avatar faces from a set of 12 grayscale images comprised of a mix of human and avatar faces. Experimental results indicate that it can be solved 62% of the time by human users with an average success time of 24 seconds and a positive user...
One of the major subjects of study in computational biology is finding the similarity between DNA sequences. Several techniques exist that are either based on alignment between sequences or are alignment-free. This paper demonstrates two techniques that are alignment-free. The first one is based on a graphical representation of the difference between DNA sequences, while the other one is based on...
Currently, most authentication system requires users to answer the CAPTCHA (Completely Automated Public Turing Test to Tell Computer and Human Apart) before gaining the system access. CAPTCHA is a standard security technology for distinguish between human and computer program automatically. The problem of using CAPTCHA is the difficulty of reading the text-based presentation, or interpreting the image-based...
Contemporary web browsers do not provide customized recommendations for the users; rather than some suggestions based on cookies or browsing history after content filtering. Usually, most of the users provide some key words to search the contents inside their preferred websites and based on these key words web servers provide the contents. So, it would be an interesting and important idea to provide...
Distance calculation is always one of the most important goals in a digital stereoscopic vision system. In an AER system this goal is very important too, but it cannot be calculated as accurately as we would like. This demonstration shows a first approximation in this field, using a disparity algorithm between both retinas. The system can make a distance approach about a moving object, more specifically,...
Web security has become a critical and challenging issue due to the growth of Internet. BOT is one of the most malicious threats to the web services. It runs automated tasks over the internet and creates problem. One solution for securing web from BOT is to develop CAPTCHA. CAPTCHA is acronym for Completely Automated Public Turing test to tell Computers and Humans Apart. CAPTCHA may be textual or...
This paper explores the ethical issues in information communication technology (ICT) in Malaysian primary schools. Among ethical issues that have been identified are cyber crime, cyber bullying, internet fraud, hacking and others. However, cyber bullying are the major ethical issues in Malaysian primary schools. In this study, quantitative methodology has been chosen by distributing questionnaire...
The ability to automatically discover error conditions with little human input is a feature lacking in most modern computer systems and networks. However, with the ever increasing size and complexity of modern systems, such a feature will become a necessity in the not too distant future. Our work proposes a hybrid framework that allows High Performance Clusters (HPC) to detect error conditions in...
Collecting data through a game with a purpose (GWAP) has become a popular approach due to its numerous benefits. However, lack of diversity in game mechanisms puts some limitations on the areas of application of GWAPs. In this paper, we introduce a new two-phase mechanism for collecting data via human-based computation games. In the first phase, the players are provided with an object and asked to...
In this paper, data acquired from five sensory units mounted on the human body, each containing a tri-axial accelerometer, gyroscope, and magnetometer, during 19 different human activities is used to calculate inter-subject and inter-activity variations using different methods and the results are summarized in various forms. Absolute, Euclidean, and dynamic time-warping distances are used to assess...
Information technology currently supports the development of human interaction with virtual environment, this development will continue in developing in the form of Human Computer Interaction (HCI). In this study, how the environment 3D virtual computer should be able to recognize human hand as part as virtual object, so it can interact with virtual environment. HCI is a study in which the relationship...
Brain computer interface (BCI) is a developing research area which aims communication between the human user and the computers by way of user's brainwaves only. This can be accomplished by processing electroencephalography (EEG) data. In this paper the aim is to build a simple BCI in terms of both collection and classification of EEG data using event related potentials (ERP). Proposed approach helps...
We live in an era where billions of computers are interconnected. In the very near future, not only computers but also many different digital devices and other physical objects will be seamlessly connected to each other and be able to communicate with little or no human intervention. These interconnected objects are called smart devices, and this concept is called Internet of Things. In this paper,...
The education of natural disaster response preparedness is getting more and more attention internationally. Nowadays, the relevant researches and development of the instructional games with the instructional theme based on a natural disaster situation are still limited. Therefore, this paper combines a design of situated learning strategy and develops an adventure game with a simulated situation of...
