34、sual information.,Note: Because attention resource is limited, when the demand of some tasks is excessive(额外的), the others must suffer.,eg: the cab driver,2007.7,Engineering Psychology and Human Performance,41,一个新的驾驶员驾驶一辆货车在城里运送容易腐烂的食物。他坐在一个用最先进技术装备的驾驶舱内。仪表板向他显示一幅标明他在城内位置的地图,对不同的目的地按其优先权以颜色进行编码并用强光加
35、以显示。该地图还配备有关交通路况的信息,并拥有一系列电子图像放大选件。在一个单独的表下面表明每次交货所要求的时间。,2007.7,Engineering Psychology and Human Performance,42,在一个阴沉的冬天,夜色降临,天下着雪。向南的公路上交通繁忙,车辆速度很快。司机俯视着驾驶舱中的地图,地图上头朝北,他试图找到他的下一个目的地,以及在即将到达的出口应该向哪个方向转弯。地图杂乱难读,相对于他的行车方向来说,地图显得乱七八糟。因此他按压了(他认为是)图像电子放大按钮,这一按使得地图上的全部目的地立即变成同样的“高优先”颜色。他向后扫视道路并检查交通车辆,然后再
36、低头看地图,试图找出当时所处的位置,并想知道是他的什么行动导致这一意外和不寻常的显示。在他的记忆中,以前课程中学习使用手册中的东西是模糊的。他突然注意到他前面的车辆已经停住,在惊慌中他突然把车转向左侧车道。他听到了后方货车一声尖锐的报警声,就又把车轮极快地转向右侧。他避开了同停在前面的车子碰撞,但开出了车道,车子抛在空中摇晃了几秒钟后跌入沟渠。由于他系上了安全带,只受到轻微伤害,但车子受到了严重的损坏,也毁坏了车上装载的易腐烂的食物。他骂这个地图,也骂自己愚蠢,试图一边开车一边固定东西,因为使用手册曾提醒他在车辆静止时使用地图的交互功能。,此课件下载可自行编辑修改,供参考!感谢您的支持,我们努力做得更好!,
