为研究车载信息服务影响下驾驶人的注视特征，设计并实施实车实验，采集驾驶人注视点数据，分析不同条件下注视点分布范围与位置。使用车载信息服务后，驾驶人对前方道路区域的注视面积显著减小，驾驶人注视点位置更接近于地面，前方道路区域平均注视比例显著减小，注视持续时间则无显著变化。比较车载信息设置于不同位置时注视分布变化，结果发现：设置于位置1时，注视分布面积与前方区域注视次数比例变化最大；设置于位置3时变化最小；设置位置2时，变化居于前两种情况之间。上述现象表明，使用车载信息服务后，驾驶人获取前方道路信息量减少，前方道路区域相对其他区域的重要程度有所降低，但信息提取难度无明显差异。此外，车载信息系统适宜的设置位置排序分别为位置3、2、1。

In order to examine the effect of IVIS ( in-vehicle information systems ) service on driver ’ s fixa-tion characteristics , data of fixations were collected while a real -vehicle experiment was conducted.The dis-tribution range and position of fixations were analyzed under different conditions.After using IVIS , driver ’ s fixation area in the road ahead decreases significantly and fixation position is closer to the ground , while fixa-tion duration reveals no significance.The distribution change of fixations was compared by setting IVIS service in various mounting positions.Results show that fixation distribution area and fixation ratio in the road ahead change the greatest in position 1, which has the smallest value in position 3 and the middle value in position 2.Based on the above phenomena , it shows that the information acquired from the road ahead to drivers de-creases of which the importance relative to other areas reduces.However , the difficulty of information extrac-tion reveals no significance.In addition , the proper position order for installing IVIS was position 3 , 2 , 1.
