Week 7 UX Observation update

 1. Flexibility and Efficiency of Use

  • Code Repository Platform: GitHub


  • Application: It allows power users to hit the 't' key on any repository page to instantly open a fuzzy-finder file search, bypassing nested folder structures and vastly speeding up code navigation.
2. Error Prevention
  • Airline Booking: Delta Air Lines


  • Application: When selecting a return flight date, the interface automatically grays out and disables all calendar dates prior to the departure date, making it physically impossible for a user to select an invalid travel window.
3. Match Between System and the Real World
  • E-Reader App: Amazon Kindle


  • Application: The digital reading interface uses a skeuomorphic page-turn animation that mimics the physical movement of flipping a paper book page when swiping left or right.
4. Visibility of System Status
  • E-Commerce Checkout: Shopify


  • Application: The checkout page features a numbered multi-step breadcrumb trail (Information → Shipping → Payment) at the top of the screen, explicitly highlighting the user's current step in the purchase tunnel.
5. Help Users Recognize, Diagnose, and Recover from Errors
  • Crypto Wallet: Phantom


  • Application: If a user attempts to send cryptocurrency to an invalid string or the wrong blockchain address format, the app throws a red error message stating "Invalid address" and disables the send button, explaining exactly why the transaction cannot proceed.

While working as a Physical Therapy Technician I often had to make use of the Raintree Electronic Health System to schedule and re-schedule patient appointments and update patient information according to the rapidly changing needs of their care plan. I observed several UX Heuristic violations that contributed to the Raintree Electronic Health system being frustratingly complicated and unwieldly to use. 1. Raintree EHR lack of feedback while performing high-stakes actions When performing certain high-stakes actions (such as collecting a payment from a patient, moving a patient's appointment to a different date, and updating a patient's insurance information) it is crucial that the user should be able to get appropriate feedback within a reasonable time so that they know what the computer is doing (for example so that they know the computer is in the process of completing the action the user requested). Without this feedback the user might suspect their input was not received an...

Amazon Heuristic Failure: Aesthetic and minimalist design (Heuristic #8) . Amazon is a very successful and widely used shopping website, but I find that its main website is actually rather poorly designed from a user convenience perspective. Upon opening the site I am immediately bombarded with five huge advertisements some of which are not at all relevant to how I or most normal expected users of Amazon would use the site (purchasing groceries, ordering food, and other niche promotions). The useful links to press are relegated to tiny words at the top of the screen and some smaller promotions near the bottom. This clearly violates usability Heuristic #8: Aesthetic and Minimalist design  in several major ways. Additionally, there is a major issue when buying multiples of one item. One woudl do this by selecting the item and using the drop-down menu found on the right above the "Buy Now" button. The price displayed above this drop-down menu will always display the price of j...

1) Ezgif.com Occasionally I will have a need to turn a moving image file from one filetype to another. For example, I might need to turn a GIF file to an MP4 file or vice versa in order to use that file on a site or for a project that requires a specific file type. In this situation I tend to use ezgif.com: As can be seen in the above image, Ezgif.com has a very simple and minimalist interface which is free from most extraneous or irrelevant information that might distract or detract from the visibility of the actually useful information (minus the unfortunate exception of the large, attention-seeking ads which are a necessary evil due to the website's business model of being free with ads).  Thus, this site fulfills the Heuristic Design princple of "Aesthetic and Minimalist design" for the most part (again, with the exception of the large and obstructive ads). However, the site has what in my opinion is a Rank 3 Usability problem which violates the "Error Preventio...
