HCI Design Project Usability Evaluation Criteria Research Paper

HCI Design Project Usability Evaluation Criteria - Research Paper Example Several criteria have been established for evaluating the usability of a user interface design in the current design paradigms. For purposes of this evaluation we shall focus on the heuristic evaluation and usability testing criteria that has been supported by several authors in the field of user interface design (Madan & Dubey, 2012). Jacob Nielsen is considered the father of Heuristic Evaluation criteria. He developed a set of heuristics referred to as Jacob Nielsen’s heuristics that are used for user interface design and evaluation to date (Inostroza, Rusu, Roncagliolo, Jimenez & Rusu, 2012). According to Nielsen, the main goal of the heuristic evaluation criteria is to identify the problems that are associated with the design of a user interface. He developed the criteria based on his experience as a long serving consultant of usability engineering (Inostroza et al, 2012). Heuristics are common evaluation techniques in the field of Human Computer Interaction (HCI) that is mainly conducted in the context of typical tasks that are performed by users. The designer obtains feedback from the users regarding the compatibility of the interface with their intended use and the performance in meeting their needs (Madan & Dubey, 2012). In a study carried out to determine usability of the Bogazici University Industrial Engineering website interface, heuristic evaluation was employed for evaluation of the usability of the user interface. To accomplish this task several scenarios were created for usability testing, user groups were determined based on their computing knowledge and skills. Their performance was then evaluated based on task completion success, time spent on the task, rate of accomplishment or quittance.

Business Research Individual Work 1 Week 3 - Essay Example In order to establish such strategies, the company can carry out research on the economic environment of the emerging nations (Apple Inc. SWOT Analysis, 2014). For example, Asian emerging economies such as India may form a lucrative market for Apple products. However, a rigorous research is needed to identify the factors defining the business market in such economies. Business research can solve Apple’s problem of venturing into emerging nations as it has the capacity to provide specific information regarding the emerging markets. For example, research can provide relevant information on the pricing strategies that Apple should rely on if it is to penetrate such markets. Moreover, research will help the Apple Company identify potential barriers that it may face as it penetrates the new markets and give it an advantage to develop strategies for addressing the challenges it may face (Zikmund, 2013). A research proposal has several components which are considered as important. The first component is the statement of the problem whereby the researcher describes the context of the research topic and describes the research question that will be addressed. The second component involves a review of the available literature. In developing a literature review, the researcher considers both relevant and recent sources related to the research topic. The third component is the statement of the hypothesis. Evidently, each research project has a set of hypotheses that it seeks to either accept or reject depending on the findings of the research (Zikmund, 2013). The fourth component is a description of the methodology to be used in the research. This involves presenting details of the sample size, the proposed sampling technique, and the instruments to be used in the research. Under methodology, the researcher also describes the research design in details and presents

Middle Ages to the Enlightenment - Essay Example Almost entire Europe had been Christianized as the 11th century reached its end. The High Medieval Era is called as medieval society’s flowering because of the intellectual renaissance that took place in the 12th century because philosophers like Thomas Aquinas and Pierre Abelard as well as because of the establishment of many universities and knowledge centers in Oxford, Bologna, and Paris (Snell, 2014).

Sexuality in Islam Essay Example | Topics and Well Written Essays - 1250 words

Sexuality in Islam - Essay Example Allah has described very dreadful punishments both in this world and in the world hereafter for the people who practice homosexuality. Allah says in the Quran, â€Å"What! Of all creatures do ye come unto the males, and leave the wives your Lord created for you? Nay, but ye are forward folk† (Qur'an 26:165 cited in â€Å"Islam and Homosexuality†). The people of Hazrat Lut (P.B.U.H.) practiced homosexuality. They practiced it both indoor and in the public. Prophet Lut (P.B.U.H.) repeatedly told them to stop this practice, but they would not listen, thus inviting the wrath of Allah and one day, those people were all destroyed together by Allah. Islam condemns homosexuality because it has myriad evil consequences. Homosexuality distorts the family system and deprives people of their gender traits. Islam allows the man to marry no more than four women at one time. Polygamy has been practiced by a lot of prophets in the history of Islam. Prophet Abraham, Prophet Moses, Proph et Jacob, and the Prophet Solomon had three, two, four, and 700 wives respectively (â€Å"An Introduction to Polygamy†). Critics say that if man is allowed to keep four wives at one time, the woman should also be allowed to keep up to four husbands at one time. But polygamy is in no circumstances allowed for the women in Islam. This makes sense. When a man marries four women, the child any of the wives would bear would be certainly his. On the contrary, when a woman makes love with more than one man at a time, there is no certainty in the child’s belongingness to a particular man unless the child is genetically tested. In addition to that, women generally outnumber men. Thus, when a man marries more than once, more women are likely to get married in their life than otherwise. Although polygamy for men is allowed in Islam, yet it is not practiced equally in all Islamic countries. Polygamy is so well-practiced by the Muslims in the Arabia, that it has also become a cultu ral trait. Polygamy is so ingrained in the Arab culture that a man keeps all the wives in the same home but in different rooms. In many Muslim countries including India and Pakistan, women cannot stand another wife of their husband. They cannot share their husband’s love with another woman. This is the reason why practicing polygamy for a Muslim man in these counties exposes him to a lot of cultural and social issues, though he is religiously justified as long as he does justice to all of the wives. There is a very sheer population of Muslim men in India and Pakistan that have more than one wife at the same time. This is purely a cultural issue. In these countries, women cannot even bear a look of their husband’s wife, what to talk of living in the same home like the Arabian women do. It is noteworthy that while Islam allows the man to keep up to four wives at one time, Islam also obliges the man to do justice to each of the four. This essentially means that a man has to distribute equal amount of money, time and assets among the wives. If a man has two wives and he lives with one more than the other, he is doing injustice and will be held accountable for his actions on the doom’s day. There are no age restrictions in marriage in Islam. A man can get married to an elder woman and so can a woman. Prophet Muhammad (P.B.U.H.) was only 25 years old when he was proposed by Hazrat Khadija (P.B.U.H.) who was 40 years old at

Situational analysis and action plan - Essay Example Through the efforts of our dedicated teachers, the school will manage to increase total pupil retention levels by a wide margin. This, unfortunately, is not enough to maintain the positive competitive edge needed to stand out as an educational leader in the 21st Century. Teachers will need to put their many talents together with the dedicated school leadership and parents and assist the school in meeting the new educational mission. That’s what we intend to find out. A series of strategy seminars are planned, as an initial path forward, to identify which teachers maintain the specific skills most appropriate for different student age groups. These strategy seminars are designed to let teachers know where the school is specifically moving as part of a path forward mentality (Bush, 2004). It is important to develop a team-based philosophy between different teachers, leaders, students and parents areas, and this intervention program will be beneficial in improving the relationship between teachers and students. These will further be designed as open forums in which questions can be proposed to teachers, school managers and concerned parents who might attend these publicized strategy seminars. Improving parent-teacher relations will only enhance the educational goals of the school and make it excel in the interpersonal group dynamic. The long-term benefits of these initial strategy sessions are to identify k ey skills with different teachers and apply relationship-based learnings to motivate students. The school requires the adopting of a systems-oriented organisation in which various interdependencies exist, such as the linkage between teacher skills and student learning. In order for one area of the school to stand as a leader, it involves personal mastery of job role function. Personal mastery refers to focusing on spirit, patience, and the

What Led to the Civil War Essay Example for Free

What Led to the Civil War Essay During the 1800’s, slavery in America became a bigger and bigger issue and discussion. The North opposed slavery and thought everything about it was wrong. Whereas the South felt slavery was an essential part of their lives, and that without it they would not survive. In April of 1861, during the first month of the Civil War Alfred M. Green delivered a speech to his fellow African Americans to join the Union forces of the North. Green uses allusions in his speech to help persuade his fellow African Americans to join the Union forces. Green felt that if anyone should be fighting in a war for freedom from slavery, it should be African Americans. He states, â€Å"My country, right or wrong, I love thee still!† Meaning regardless how wrong the South’s actions were or could be at times, Green and his people would still love them and fight for what was right. African Americans needed the extra boost of confidence, and Green was just that. He says, â€Å"Let us, take up the sword, trusting in God, who will defend the right†¦Ã¢â‚¬  By bringing in this statement of faith this made the tone more comfortable and reassuring, as if God was on his side, and would do the right thing in the end. The passion and drive of Green would overall have a great impact on African Americans. Green says, â€Å"Remember, too, that your very presence among the troops of the North would inspire your oppressed brethren of the South†¦living God the God of truth, justice and equality to all men.† This created a new confidence for the North and slaves that wanted to make a difference in how they were being treated. Given these points, Green uses personal experiences and emotion to help
