If there are too many items, the window would scroll horizontally to view the rest of the items. From there, he or she can click to add to the order or close the prompt. Within the Scenario Jane and Julie are deciding which seafood dish they want to order. Jane wants something cheaper whereas Julie wants one with less fat. Usability Analysis Learnability It is standard for items to be compared to be displayed horizontally and there is not much functionality on this page, so it should be easy to learn. There is a scrollbar at the bottom for that they know they can scroll the panel horizontally. Efficiency The horizontal scrolling attempts to make it easy to view a lot of items on one screen. The table view makes it easy to compare the same facts for all items. However, If the items aren't side by side and far away, it is inefficient to compare the two item's facts. The users can remove items from here and add them straight to their order also. Safety If you accidentally click the close button, it is easy to open it again from the view screen. The user cannot edit much other data. If the user accidentally clicks the add button, the confirmation prompt will pop up so it is easily reversible. |
