Assignment 6 User Testing

Now the final pieces fell into place as we created test materials and recruited participants.

Assignment 5 Ready for Testing

Goal of prototype

The goal of the mobile app is to simplify vehicle maintenance tracking. Specifically, this prototype focuses on the procedure for entering mileage at the time of filling up the fuel tank.

Before moving forward on our high-fidelity prototypes we needed to enumerate the issues found during the heuristic evaluations.

Assignment 4 Start Building

In Assignment 4 we began the process of creating a high fidelity prototype based on one of the wireframes we made in Assignment 3. I selected CarBuddy prototype 2.

But first we needed a plan--a development plan

HCI Course Part 4 - Heuristic Evaluations

An important part of this course is the peer review and self-evaluation process. If you take the process seriously you can learn a huge amount by evaluating the work of other students as well as your own work. Each assignment has a grading rubric to help you figure out what kind of feedback to give and how to score.

The peer review and self-evaluation process for Assignment 3 Wireframing also gave us a chance to practice a common UX technique: heuristic evaluations.

What are heuristic evaluations?

HCI Course Part 3 - Wireframing

This is part three in my series about the Human-Computer Interaction course I took through CourseraRead all my posts for the full story.

Assignment 3 Wireframing

After choosing a concrete direction (Mary Jo's Storyboard in my case) we jumped into the process of prototyping by creating two rapid interactive wireframes that varied in interface, but offered the same basic functionality.

The process of rapid prototyping involves producing your ideas quickly and testing them. Confirm if your designs work as planned. Based on what you learn from those tests make more designs and refine previous ones. Test more. Refine and adjust. Test. Repeat again. Iteration upon iteration to improve and refine the design.

HCI Course Part 1 - Needfinding

As I mentioned previously, during April & May 2013 I participated in Scott Klemmer’s Human-Computer Interaction course from Stanford Online.

In this course, you will learn how to design technologies that bring people joy, rather than frustration. Helping you build human-centered design skills, so that you have the principles and methods to create excellent interfaces with any technology. (more)

Personas for Everyday Use

Recently I found myself helping a friend who was stuck while trying to write the cover letter for a job application. Now I know she's not the only person to have writer's block in this situation. After stumbling around for a while I came upon a solution that will hopefully help you as well:

Write a persona for the recipient of the cover letter. 

To Buy or Not to Buy

Recently I found myself on the hunt for a new-to-me used car. After researching at places like Edmunds and Kelly Blue Book I proceeded to scour car dealers' websites for my preferred makes and models. Since this was my first time buying from a dealer I had a lot of questions. The questions I started out with were about the cars.

The questions I ended up with were about the websites.

For example, I selected a car from South Point Hyundai's list of used cars and saw:

This is a partial list of questions I had while looking at the page:

Hyundai questions

The questions I had about the page as a car buyer fell into two general categories: how can I find information about this specific vehicle being offered (features, price, etc) and why are there different buttons and links that seem to be the same thing?

Now I assume that the goal of a car dealer's website is to get you to come in person to see the car you want and then, depending on the specific dealer's philosophy, possibly up-sell you to a newer, more expensive car.

Here's my redesign to address my questions as a car buyer while also focusing on the dealer's goal:

Hyundai revamped

First to address the consumer's need for information specific to this vehicle:

  • Add more photos of the actual vehicle being offered.

  • List features and options available on this specific vehicle in the second tab (possibly renamed).

  • If the advertised price is not available place an obviously click-able link to request the price.

To minimize buyer's confusion and information overload:

  • Remove one of the "Make an Offer" links.

  • Remove the "Request More Information" link (the "Ask a Question" link provides the same service).

  • Consider hiding the "Calculate Payments" box on pages without an advertised price.

For the car dealer's goal to get you to come in person and possibly up-sell the purchase:

  • Give the top right highly prominent spot on the menu the command to "Test Drive Today".

  • Directly under that, list location specifics and the hours open. Presenting these details removes the need to click through to a different page and the need to determine which departments' hours are relevant. That means a buyer could drop everything to run to the dealer immediately without the need to wait for another web page to load.

  • Add a third tab at the top to provide the details of this year's version of this vehicle. This allows consumers to easily sell themselves on the newest model because it has all those extra features they want.

As for me, I did find the car I wanted at a different dealer, one whose website quickly and painlessly answered my questions.
