Usability and Heuristic Evaluations

 This week we read about usability and the User Experience. Usability refers to how well a product or system can be understood, learned, and used by its intended audience. A system's usability can be assessed through multiple methods, such as surveys, user testing, and expert evaluations. Nielsen's Heuristics, developed in 1994, include these 10 principles to determine usability: visibility of system status, a match between system and real world, user control and freedom, consistency, error prevention, recognition rather than recall, flexibility, aesthetic and minimalist design, help to diagnose errors and recover, and help and documentation. 

    Utilizing Nielsen's heuristic principles, I have chosen the Blue Layne shopping app to evaluate. 

Visibility and system status: the app provides a clear loading screen

User control and freedom: the user has the freedom to use the search option for item lookup by name, the drop bar, or the tabs at the top of the screen to search by category

Aesthetic and minimal design: the interface is simple and clean. 

error prevention: Errors occur when trying to use discount codes. 

recognition rather than recall: the app uses clear labeling 

Match between system and real world: the app uses familiar icons, such as the shopping cart for checkout and the swipe feature.

Week 6: Etsy UX

 1) Visibility of system status:        - The design should always keep users informed about what is going on, through appropriate feedback within a reasonable amount of time.        - When searching for items, the Etsy app clearly shows the loading screen for the user to see that the app is working on loading the appropriate matches to the user's search.  2) Match Between system and the real world:     - The design should speak the users' language. Use words, phrases, and concepts familiar to the user.      - The app uses familiar terms and icons located throughout the app. An example, the icons located at the bottom of the screen show a magnifying glass, heart for favorites, and a cart icon.  -this is a good use 3) Flexibility and efficiency of use:     - Shortcuts--hidden from novice users--may speed up the interaction for the expert users such that the design can cater to both inexperienced and...

Airbnb UX

  1) Flexibility and Efficiency of Use:         Shortcuts-hidden from novice users- may speed up the interaction for the expert users such that the design can cater to both inexperienced and experienced users. Allows users to tailor frequent actions. The user has the flexibility to add the number of days of flexibility or add specific dates they wish to travel.  The user also has the option to display the total price when searching, so there are no hidden fees at the end. This feature is displayed with the toggle at the top of the page.  This is a good use.  2) Recognition Rather than Recall:     Minimize the user's memory load by making elements, actions, and options visible. The user should not have to remember information from one part of the interface to another.      The airbnb app uses many icons to show the amenities in the home. This allows the user to glance at the icons instead of having to read through the text....
