A button that feels obvious with a mouse may be difficult to reach with a keyboard. A gesture that works well on one screen may be unfamiliar on another. Interaction depends on both the interface and the way a person approaches it.
Well-considered software gives important actions clear names and recognizable states. It also avoids making a single gesture or a precise pointer movement the only way to finish an ordinary task.
Explore a familiar tool with an input method you use less often. Notice where the next action remains clear and where it disappears. That small exercise can reveal the difference between an interface that looks complete and one that supports a wider range of use.
An example to consider.
Imagine controlling a presentation from several steps away. A large, clearly labeled action can help when precise pointing is inconvenient.
Put it in perspective.
A helpful explanation gives the reader enough context to act. More detail can wait until the next question makes it useful.
- Try an important action with a keyboard.
- Look for clearly named controls.
- Notice where an alternative input changes the task.
