- 1. Some controls, such as scrollbars, compound the problem by forcing users to switch back and forth between fine and gross motor skills several times to complete an interaction (see Figure 19-1).
- 某些控件，比如滚动条，在交互时混合了这些问题。 强迫使用者在精细运动和粗略运动之间转换几次，才能完成一次交互（如图19-1所示）。

- 2. Focus tends to be broad at the start, aimed at gross structural and goal-oriented issues, and more narrow for interviews at the end of the cycle, zooming in on specific functions and task-oriented issues.
- 在开始时关注点比较广泛，针对的是总体结构和与目标相关的问题。 在这个周期的最后阶段，范围则比较狭窄，关注点变成了特定的功能及与任务相关的问题。

- 3. This means that a user can make the initial gross movements with the mouse, then make a final, precise placement with the arrow keys, and release the mouse button without disturbing the placement.
- 这就意味着用户可以利用鼠标粗略地开始移动，然后利用箭头键精细地确定最终位置，而且在释放鼠标时也不会干扰位置。

- 4. Transitioning between gross and fine motor skills is challenging.
- 粗略运动技能并不比精细运动技能快或慢，但二者之间的转换是困难的。

- 5. It involves a gross shifting of attention that disrupts a user’s flow and forces him into a new context.
- 在窗口之间导航涉及注意力的整体转移。 这会打断用户的流，强迫他们进入新的情境。

- 6. When you lift the heel of your hand from the desktop to make a larger move, you use the gross motor skills of the muscles in your arm.
- 当你抬起手做更大的移动时，你使用的是手臂肌肉的粗略运动技能。

- 7. Similarly, moving the mouse cursor across the screen to manipulate a control forces a change from fine to gross and back to fine motor skills.
- 基于同样的原因，也不喜欢跨越屏幕位置来移动鼠标操作控件，因为这样不得不需要在精细运动控制和粗略运动控制之间进行转换，然后又回到精细运动控制。

- 8. This direct-manipulation operation is more demanding of users because of its juxtaposition of fine motions with gross motions to click, drag, and then release the mouse button.
- 这个直接操作对用户要求更高，因为它结合了粗略动作与精细动作来单击、拖动和释放鼠标。

- 9. This behavior makes sense, since scrolling over long distances requires gross motor movements that make it difficult to stay within the bounds of the narrow scrollbar control.
- 这种行为很有道理，因为长距离的滚动需要粗略运动控制，使其难以保持在滚动条控件的范围内。

- 10. Further, if the cursor starts far away from the desired control, the user must first use gross motor control to move the cursor near the control before shifting to fine motor control to finish the job.
- 但如果光标远离目标控件，则用户必须先用粗略运动控制来移动光标接近控件，然后改成精细运动控制来完成工作。
