Through mathematics, this paper works to analyse the Index of Difficulty in ISO9241-Part 411: Evaluation methods for the design of physical input devices. It was proven that all the target circles always intersect for very low Index of Difficulty; which conjectured to disturb the experiment or affect the focus of the subject. Some examples are provided, in addition, to support the proof. We hope this proof will contribute to the improvement of ISO9241, where the result might become a special attention to the designer of the experiment in human-computer interaction field; especially in checking the influence of overlap area in the human factor.

While the concept of enaction is not new, recent trends on the use of contemporary devices to interact with computational systems have attracted the attention in the field of interaction design. A quick look in the literature reveals different meanings for an enactive system, depending on the knowledge domain. This paper explores the subject by conducting a Systematic Literature Review to construct a big picture on the subject. Results reveal the paths being traced and issues still unexplored that offer opportunities for investigation in the human computer interaction field.

Interaction methods based on computer-vision hold the potential to become the next powerful technology to support breakthroughs in the field of human-computer interaction. Non-invasive vision-based techniques permit unconventional interaction methods to be considered, including use of movements of the face and head for intentional gestural control of computer systems. Facial gesture interfaces open new possibilities for assistive input technologies. This chapter gives an overview of research aimed at developing vision-based head and face-tracking interfaces. This work has important implications for future assistive input devices. To illustrate this concretely the authors describe work from their own research in which they developed two vision-based facial feature tracking algorithms for human computer interaction and assistive input. Evaluation forms a critical component of this research and the authors provide examples of new quantitative evaluation tasks as well as the use of model real-world applications for the qualitative evaluation of new interaction styles.

This chapter focuses on HCI aspects to overcome problems arising from technologies and applications that may hinder the normal teaching process in ICT-ready classrooms. It investigates different input devices on their usage and interactivity for classroom teaching and argues that pen-based computing is the mode of choice for lecturing in modern lecture halls. It also discusses the software design of the interface where digital ink, as a “first class” data type is used to communicate visual contents and interact with the ICT.

Fear of flying is a common problem that many people have to face. As varied as the causes may be, all kinds of fears have many aspects in common. Much is known to us about fear, and the fields of psychology and psychiatry teach us that many times we can conquer fears simply by exposing the subject to the dreaded object. Human-Computer Interaction has branched even in this direction, including the treatment of phobias. With the help of Virtual Reality researchers around the world have recreated using a computer the way that psychologists and psychiatrists cure fears, adding a twist. Many times patients are supposed to go the extra mile and expose themselves, little by little, to what they are afraid of. Virtual Reality brings this type of exposure directly to the patient, with the comfort that such fear can be stopped at any time, since it is only a computer simulation. The most successful studies have been performed on arachnophobia, or the fear of spiders. There are also studies that deal with the fear of heights and the fear of public speaking. Some studies have also been performed on addressing the fear of flying using a virtual environment. This work is a review of such methods, and an explanation of the principles behind the motivation for these studies.

A great deal has been written, especially in the last few years, on the subject of collision at sea. The increase, however, in the speed of ships and in the density of traffic so magnifies the complexity of the problem that even closer and more earnest study is still called for. Three fields of inquiry demand our attention: technical advances, procedure, and the human factor. Of these, the widest and most promising might seem to be the first. Its importance is undeniable, and I am by no means the only one to have pointed out that with the new difficulties it raises it supplies also the appropriate solution. Even wider, however, and more complex is the field of human study; this covers both the others, for in this the final objective is to enable men to master what they have won for themselves, and this they cannot do—here we meet the familiar problems of philosophy, ethics and religion—unless they first learn to master themselves.Compared with these two fields, the technical and the human, that of procedure must at first seem quite insignificant. Can one seriously imagine that there is in fact some new method of avoiding collisions, so abstruse that no one has yet been able to discover it? In my small book on the use of radar I wrote: ‘The Regulations envisage two ways of avoiding collision:1. A movement carried out in concert with the other vessel.2. A reduction of speed, if necessary to zero.

During the time of Imam al-Magrizi (766-845 H), inflation had occurred in Egypt. Al-Magrizi shows about the theory of inflation. Inflation becomes a discourse that studied heavily in the subject of the economy. Al-Magrizi is an Islamic economic thought who did a particular study of money and inflation. The paper focused on al-Magrizi inflation theory caused by two factors, namely natural factors and human error factors. To solve these factors, a nation could apply Islamic monetary policy to Umar Chapra's thought, namely a credit-oriented (financing) location as a solution of natural factor theory. Also, moral suasion or moral appeals as a solution to the human factor inflation theory.

Technological artifacts, physical and digital, have occupied an increasing space in society. Through these artifacts, individuals’ access, store and share information, which may be spread across different equipment. On the other hand, through human-computer interaction, individuals use and appropriate this equipment, creating an ecology of artifacts that appears to be able to expand the physical and mental capacities of its users. In turn, the aforementioned expansion of capabilities seems to contribute to changes in the informational behavior of users of artifact ecologies during practices such as personal information management, the passage from information to knowledge, and the management of personal knowledge. However, there seems to be little literature relating concepts such as human-computer interaction through the use or appropriation of an artifact ecology, with informational behavior, and the aforementioned management of information and personal knowledge. This scarcity reduces the information available, the understanding of these relationships, and their action on the individual. That said, this work will start from a brief systematic review of the literature, to learn about recent works developed on the subject investigated. Afterward, the recovered literature will be confronted with each other, to find relationships between the concepts. The results obtained from this confrontation will contribute to informing other investigations related to the appropriation of artifact ecologies, for information management practices and personal knowledge.

The article highlights some issues that form the behavior of the driver as the main participant in road traffic environment. It is shown that, along with individual psychological characteristics that influence vehicle control, there are also some social norms and rules acquired by the driver both at the interaction level (for example, peer influence) and in organizational and structural formalities (for example, pressure from other road users), that will affect his or her driving. The interaction of individual and social factors with environmental factors (infrastructure and formal rules) substantially complements the concept of the specific behavioral manifestations of the car driver. The article presents a brief overview of the main areas of applied research in modern traffic psychology, which allow for a more detailed consideration and a better definition of the “subject matter” of this direction within the framework of the study of the human factor in a traffic environment, as well as its overall impact on road safety.

Color-capture systems use color-correction processing operations to deliver expected results in the saved image files. For cultural heritage imaging projects, establishing and monitoring such operations are important when meeting imaging requirements and guidelines. To reduce unwanted variations, it is common to evaluate imaging performance, and adjust hardware and software settings. In most cases these include the use of ICC Color profiling software and supporting measurements. While advice on the subject by experts can be deftly persuasive, discussions of color goodness for capture are clouded by many imaging variables. This makes claims of a single, color-profiling approach or engine moot in the context of a greater workflow environment. We suggest looking outward and considering alternative profiling practices and evaluation methods that could improve color image capture accuracy and consistency.
