Design 2: Text-based interface
Learnability
- Learnability for this interface is generally low, since users have to keep knowledge of commands and valid tags in their head, rather than having that knowledge available "in the world."
- In addition, text based interfaces are very uncommon in web applications, so even user familiar with such interfaces may be caught off-guard.
- However, its resemblance to a Unix shell may increase learnability for users who are familiar with Linux or who use the command line frequently
...
- For expert users, this interface is extremely efficient, since all most of the input is done on the keyboard.
- However, things like scrolling through a long list of items will suffer in efficiency, since we are prohibiting use of the user must switch to using the mouse.
