...Analyzing the results of Usability Testing By Ben Homrig and Justin Stephenson For our presentation, we were assigned with analyzing the results of usability testing. Usability is defined as the process or technique used to interactively test and assess the user-interface of a product, method or set of instructions. Presenting and analyzing data are very important steps in process. The improvements developers and technical writers make with their data define exactly how the end product will be when completed. Understanding the differences in the types of data tabulated is vital to understanding how results are analyzed. In usability testing, there are two types of data – qualitative and quantitative. Quantitative research must measure the products in an objective, quantitative and statistically valid way. This type of data recorded must be hard evidence, free of context and exact. Qualitative data is collecting, analyzing and interpreting data by observing how people respond through their opinions and actions. Data is generally collected through gathering information from focus groups and in-depth interviews with users. Quantitative research is defined as objective, while qualitative is subjective. The differences between qualitative and quantitative data are very important in improving a product, method or set of instructions. In our case, we established our primary example as that of a tester documenting the experience a user has while trying out a new iPhone game application...

...Paid Website Usability Testers Kazi Ziaul Islam Strayer University Human Computer Interaction CIS375 Prof. Kourosh Samia December 8, 2014 Paid Website Usability Testers Two attributes determine if a website is useful and they are usability and utility. Utility is whether or not the website provides the required information or features. Whereas, “usability is a quality attribute that assesses how easy user interfaces are to use.” (Nielsen, 2012, para. 1) You cannot have one without the other. Suppose your site is brimming to the top with lots of information and has all the bells and whistles, but if the Interface design (ID) is poor and as a result the User Experience (UX) suffers then no one is ever going to spend the time and effort to discover those great features. This is the main reason why companies must perform usability evaluation. Although the heuristic evaluation method may take less time and is usually less expensive, the “heuristic evaluators could not play the role of real users and could not predict actual problems users might face while interacting with the sites” (Hasan, Morris, & Proberts, 2012, p. 726) User Testing is essential prior to going live in a production environment and can done on a budget. Katie Sherwin of the Nielsen Norman Group reiterates that “testing doesn’t have to be expensive and by testing with just 5 users, you can uncover 85% of the issues.” (Sherwin, 2014, para. 8) After all it is an iterative process and the law...

...school after so long has been challenging. In addition to having to get back in the swing of doing homework and fitting in school with work and a family I have also had to learn computer systems necessary to take the classes and complete the work. Luckily Most of the programs I have worked have been user friendly and straight forward. I have found out from my research that I have been lucky inn this aspect. I have read about other students experiences with some programs we use and the difficulties they have. I think faculty does a good job of making each class user friendly. The fact that GUI uses the same five-module learning structure is also beneficial to students. This system would meet the learnability and memorability components in a usability test. Students become used to the same system and it stays consistent throughout their schooling which is a bonus. The security of the site is also well maintained. To operate through the system, going from class to library for example, there has to be sign on for each site. This is important for security reasons but can be a little redundant at times. I think if there was a way to secure this site and keep continual uninterrupted access to all domains on the site it would be more productive for the students. GUI faculty should request ongoing feedback regarding their site. The feedback should come from students, faculty and anyone involved in maintaining the site. Ongoing user feedback is helpful in keeping the site current to the users...

...2.2 Usability Evaluation Techniques 2.2.1 Pluralistic Usability Walkthrough The Pluralistic Walkthrough (also called a Participatory Design Review, User-Centred Walkthrough, Storyboarding, Table-Topping, or Group Walkthrough) is a usability inspection method used to identify usability issues in a piece of software or website in an effort to create a maximally usable human-computer interface. The method centres on using a group of users, developers and usability professionals to step through a task scenario, discussing usability issues associated with dialog elements involved in the scenario steps. There are however limitations due to this technique being only as quick as the slowest person in the group. 2.2.2 Heuristic Evaluation A heuristic evaluation is a usability inspection method for computer software that...

...Usability of iPads and Websites Name Professor Course Date The tablet market is growing at a high rate, the iPad being the best selling in this segment. The iPad has many uses such as; streaming videos, playing games and surfing the internet. However its usability has come under critics from several parties. The purpose of this research is to evaluate the usability of the iPad from a consumer stand point. In 2011, the Nielsen Norman conducted a research on the usability of the iPad, and published a report. A total of 26 apps and 6 websites were tested. Many apps which the participants had installed on their iPads were also tested. Sixteen users participated in the research who were evenly distributed in terms of gender. Their average age ranged between 21 years and 50 years. The tests included; the usage of gestures, implementation of the back buttons, and the organization of the app or website. The findings of the tests were; usage of splash screens in websites and apps, squeezing of information into very small areas, making it hard to recognize, usage of excessive navigation methods and over usage of the swipe gesture in the apps. Despite the efforts being made by the developers to make iPad apps and websites more usable, there is still a large room for improvement as indicated by the test findings. The use of gestures is an inconsistent interaction design as described by Nielsen. The user interface differing from app to app is the most frequent inconsistency he...

...Running Head: USABLE SECURITY THE IMPLEMENTATION Usable Security the Implementation Name Institution Abstract This project was about usability security and its implementation. It involved the designing and development of a suitable human computer interface to provide a log on module for the Kuwait armed forces computer system. The development focused on relieving the user from the load of creating, remembering and maintaining their passwords for the login process. Based on the fact that the Kuwait information and communication technology literacy levels are still in their infancy stage, the conventional authentication system was proved unfriendly to the user. This system was developed with this in mind. This proposed system relies on the user logging in to the system after identifying five pictures they uploaded earlier from among a grid of twenty five pictures. By selecting the five correct pictures which they uploaded, the system was able to successfully authenticate the user. Using these pictures greatly reduced the mental load on a user who was required to remember strong passwords that ended up being compromised (Badre 2002). The use of pictures or graphical images for authentication or access control is a practice called biometrics that is gaining popularity in establishing system security today. Due to the need to deliver a solution in the shortest time possible the...

...Phillips.Kieran | | | Purpose The purpose of this website is to be largely promotional and raise the status of Monmouth and the surrounding areas as a destination for overseas visitors. In achieving this, the website is designed to be informational, educational and to encourage tourists to visit and stay in the area. Availability and Accessibility Starting with the basic, yet key aspect of usability, I will be discussing the availability and accessibility of the site. If people try to access the website and it doesn’t work — for whatever reason –the website becomes worthless. An example is server uptime, it’s important to ensure the possible or current visitors don’t get an error trying to load the site therefore it will be wise to invest in good hosting which will be done. Another example is broken links, it is essential to double check that there are no dead links on the site. Another key aspect to consider is Mobile responsiveness, ensuring that the site can handle different screen sizes and slow connections. Clarity The second key aspect to usability is clarity. If you distract or confuse your visitors, they will either need more time to find what they came for, or they might forget their initial goal all together. Either way, they will not experience the website as user-friendly or chances are that they will leave dissatisfied and with no intention of coming back. This is why I have decided that a clear and usable design can be achieved through: ...

...Introduction: How has it that a dream has now become the life and blood of our world’s economy? The internet has grown from a twinkle in our eye to an everyday commodity. We use the internet when we leave our house with our Smartphone’s, iDevice’s, and device’s in our vehicles. As the expectations from the users increase the developers have to meet those expectations. If a company does not meet the needs of the users, then the user will become impatient and go elsewhere. We designers need to keep the design up-to-date to keep the interest of the users there; content also needs to be current. Constant testing is a must for any website, with the constant changing languages, and programs. Layout is another item that needs to be updated continuously. I could go on, but below is the break-down of ten of the rules for website navigation: 1 – Design: This need to be something that has to up-to-date, interesting, and appealing to the users. To get this process started we need to imagine and/or draw our final projects design. This includes, but not limited to, the potential of the site, how many pages the site will have. This will need to be accomplished to succeed with all the alternatives there are out there on the web. So to succeed there will need to be input from several sources and have them evaluated for the best choice to use. This will show us the users’ opinions, wants, and needs that will make your site stand out amongst the others. Performance should be the number one thing...

...the meaning of usability. 2. The student learner will describe the meaning of practicality. 3. The student will identify and explain four questions that help faculty in selecting appropriate assessment procedures. Usability is simplifying the use of a system or product with effective results. Practicality: Looks at the effectiveness and quality of the systems or products being used. For example, when testing the instructor uses a test pamphlet and scantrons. Using scantrons would make it easier for her to grade tests and would also provide accurate and consistent results. This is an example of both usability and practicality. Four questions/factors can be used to help guide faculty in selecting appropriate assessment procedures: 1.How easy is...

...Exercise 6.1 Reviewing the Chapter 1) Document Design is important in business communication because when it is poor, both organizations and society suffer. It is important because an attractive document looks friendly, inviting, and easy to read. The visual grouping of ideas makes a document’s structure more apparent. Good document design can save time and money, build goodwill and reduce legal problems. 2) The four level of a document design are: a) Intra- level which is Design choices for individual letters and words. Intra-level design choices include the font and its size you choose; whether you use bold, Italian, or colors changes to emphasize key words; and the way you use capital letters. b) Inter-level which is Design choices for blocks of text. Inter –level design choices include the ways you use headings, white space, indents, lists, and even text boxes. The headings and bulleted lists that organize information on this page are inter-level choices. c) Extra-level which is Design choices for graphics that go with the text. Extra-level design choices include the way you use pictures, photographs, data displays, charts, and graphs, and which you emphasize information on those graphics. d) Supra-level which is the Design choices for entire documents. Supra-level design choices include paper size, headers and footers, and the index and table of contents, as well as color schemes and layout grids that define the look of all sections of a document. 3) Guidelines for...

...Task analysis and human-computer interaction: approaches, techniques, and levels of analysis Abe Crystal School of Information and Library Science University of North Carolina at Chapel Hill acrystal@email.unc.edu Beth Ellington School of Information and Library Science University of North Carolina at Chapel Hill elliv@email.unc.edu ABSTRACT In this paper we critically review task analysis models and techniques. These approaches to task analysis are discussed in order to develop a richer picture of human activity, while analyzing their limitations, general weaknesses, and possibilities for improvement. We consider their ability to determine the appropriate set of atomic actions in a task, their effect on workers’ motivational needs, their support of users’ cognitive and sociocultural processes, and their effectiveness in supporting interface design. We note that the major approaches have focused on very different levels of analysis, and call for greater integration of these different levels in task analysis theory. Keywords Task analysis, cognitive modeling, activity theory. INTRODUCTION Practitioners and researchers routinely advocate building user-centered systems which enable people to reach their goals, take account of natural human limitations, and generally are intuitive, efficient and pleasurable to use (Preece, Rogers and Sharp, 2002). Central to the design of such systems is a clear understanding of what users actually want to do: What...
