Second Individual-Student Assignment I’d like each student to write a paper describing

Second Individual-Student Assignment

I’d like each student to write a paper describing a heuristic evaluation (Ch. 16) and cognitive analysis (Ch. 4) for two comparable, interactive products for performing the same tasks. The products have to be different than the ones you evaluated for your group project and first individual-student assignment. The paper needs to have the following information:

Introduction

The purpose of the products from the perspective of one primary user group.

A brief persona (Chap. 11) describing the user requirements (i.e., characteristics) for that user group. One user requirement is that users represented by the persona have never used either product. They are first-time users. What are other user requirements for your persona? Remember to give your persona a name.

A description of two important tasks that those users need to be able to perform with both products, and your rationale for selecting the tasks. Your tasks also need to emphasize the human-computer interaction (HCI) process. So, please, no overly simplistic or trivial HCI tasks.

Your usability goal requirement and user-experience (UE) goal requirement for each task, and why you selected them. Remember, your goal requirements need to be defined in a measurable way so that we can test whether they’ve been achieved or not by five or more users matching your persona’s characteristics, as in your group projects. Your goal requirements will be the same for both products.

Product Description

I suggest that you describe each product separately.

Describe each product’s conceptual model, interface metaphor(s), interaction type(s), and interface type(s).

Then, provide an overview of each product’s human-computer interaction process. (This overview should be a brief introduction to help the TA and me follow the walkthrough.)

A step-by-step, display-response walkthrough (Ch. 16) for each product for each task.

You do not have to present many, if any, screen shots. Just describe the steps in enough detail so that I can understand how users with your persona’s characteristics performs the same two tasks with each product. If you need a lot of screen shots, put them in an appendix. Having an appendix is voluntary and will not count toward your page total.

Think about the three questions for walkthroughs: (1) will users know what to do? (2) see how to do it? (3) know if they’ve done it correctly or not? You do not have to write the answers. However, thinking about them should help you perform your heuristic evaluation and cognitive analysis.

Heuristic evaluations for the two products

Briefly, describe your procedures for doing the heuristic evaluation (HE) for both products. I want to understand how you did your HE. Make sure to:

Use the ten heuristics on pp. 550-551 of our textbook (Ch. 16, slide #5)

Do the HE for both tasks for each product

And, then, go beyond the tasks to see if there are heuristic violations (e.g., for other tasks) that will help you differentiate between the products

Describe the results of your heuristic evaluation. In particular,

Indicate how well each product performed, in general, on each of the ten heuristics, and why. Briefly describe heuristic violations for each product, if they exist. Think about presenting your results in a 10-heuristics (rows) by 2-products (columns) matrix (summary table).

Then, for each product, give two detailed examples of heuristic violations. (I am particularly interested in violations tied to your tasks, but feel free to describe violations not tied to your tasks if you prefer.)

If there are no violations, give two examples for each product to show how it performed so well on two heuristics of your choice

If there is only one violation, then describe that violation and also give another example where the product performed well

Conclusion? Is one product better than the other based on your heuristic evaluation? Why?

Cognitive analysis of the two products

After doing your heuristic evaluation (and walkthrough), analyze how well each product supports the cognitive processes of (1) attention, (2) memory, and (3) mental model development for new users with the characteristics of your persona.

I’m assuming that you’ll emphasize the step-by-step, display-response walkthrough (Ch. 16) for each product for each task in doing your cognitive analysis. However, please don’t hesitate to include other tasks or information if they help you do your cognitive analysis for each product.

Make sure to tell me the adequacies and/or inadequacies of each product in supporting each of these cognitive processes for new users with the characteristics of your persona. Please make sure to define and address the following concepts:

For Attention – how well the products support human, top-down and bottom-up processing, and the flashlight analogy.

For Memory – the three processes of encoding, storage, and retrieval, and the “limited fuel” analogy regarding human, working memory’s capacity and duration limitations (without rehearsal).

For Mental Model Development – using Slide 28 in Chapter 4 as a guide, please describe how well the products help new users with your persona’s characteristics learn accurate mental models.

Conclusion? Is one product better than the other based on your cognitive analysis? Why?

Conclusion: Based on your heuristic evaluation and cognitive analysis

Will new users with the characteristics of your persona be able to use each product to achieve your usability and user-experience goal requirements for each task? Explain why for each task for each product. (Do not do a usability test.)

Do you think one product is better than the other? Give a detailed explanation that utilizes the results of your heuristic evaluation and cognitive analysis.

Recommendations for improving each product based on the above analyses, and why. (Note: Even if your analyses found no problems with a product, I’d still like you to recommend at least one product improvement based on your knowledge of the product. Make sure to tell me why you’re making the recommendations.)

Please use your last name and then 2nd assignment as your file name. For example, my file name would be Adelman – 2nd assignment.

Please put the paper’s title and your name at the top of the first page of the paper. The paper should be from 3 to no more than 6 pages in length, single-spaced, 12-point Times New Roman font. (There is a 5-point penalty for each page greater than 6 pages, not counting an appendix.) Please make your paper easy to read.

I have provided a grading guide/rubric on page #4 containing bullet points corresponding to the above bullet points. The bullet points in the grading guide identify the information that I want in your paper, and how many points that information is worth. So, please use those bullet points as section headings for your paper. That will make sure that your paper (1) contains all the required information, and (2) that the TA and I can find it easily. So, for example, the first major heading should be Introduction; the first subheading (or bullet) under it should be Purpose; the second subheading (or bullet) should be Persona; etc.

Say that you are aware of and conform to the GMU Honor Code at the end of your paper. Any violation of the GMU Honor Code will result in a zero on the paper. I also may send the case to the Office of Academic Integrity. Please remember, this assignment is in place of an exam. You are absolutely not allowed to work with anyone else on it or plagiarize (copy) from any source.

The assignment is due in Blackboard on Thursday, December 9th, by 9:00 AM. You may email it to me if you’re having problems uploading it to Blackboard. There will be a 7-point penalty if I don’t receive your paper by that time. There will be an additional 7-point penalty for each day the paper is late. For example, a total 14-point penalty if the paper is submitted after 9:00 AM on December 10th; a total 21-point penalty if submitted after 9:00 AM on December 11th; etc.

You may earn from two (2) to eight (8) extra points if you submit your paper before the due date. However, you may only submit your paper once. So, please make sure that your submission has all the necessary information.

I hope you do great on the paper!
