内容总结：

近日，美国华盛顿大学与丰田研究院合作开展的一项研究显示，车载触控屏会显著分散驾驶员注意力，影响行车安全。该研究结果已于今年秋季在韩国釜山举行的ACM用户界面软件与技术研讨会上发布。

研究团队通过驾驶模拟实验发现，当驾驶员在行车过程中操作触控屏时，车辆更容易偏离车道，同时触屏操作的准确性和速度也会明显下降。实验中，参与者在完成记忆测试任务的同时，需操作12英寸触控屏上的指定目标，模拟实际驾驶中使用车载应用的情景。传感器全程监测了驾驶员的视线、手指动作、瞳孔变化及皮肤电反应。

“随着传统物理按键逐渐被触控屏取代，科学评估触屏交互对驾驶安全的影响至关重要。”华盛顿大学信息学院教授、论文共同资深作者雅各布·沃布洛克指出，“我们的研究为优化车载界面设计提供了实证依据。”

研究建议，未来车载系统可通过眼球追踪或方向盘触感传感器实时监测驾驶员的注意力状态，并动态调整触控界面——在驾驶员注意力分散时突出关键控件，简化操作流程，从而提升行车安全性。该成果有望帮助汽车制造商设计更安全、更人性化的车载交互系统。

华盛顿大学最新研究提醒您：驾驶时请勿分心查看屏幕。随着传统仪表盘旋钮和按键逐渐被取代，该校与丰田研究院合作探究现代车载触控屏对驾驶行为的影响。研究成果将助力汽车制造商设计出更安全、响应更灵敏的车载屏幕与人机交互界面。

研究团队今年秋季在韩国釜山举行的ACM用户界面软件与技术研讨会上发表的这项研究，进一步揭示了使用手机导致分心驾驶的危害性。据华盛顿大学报道，在驾驶模拟器中使用触控屏（见上方视频）的参与者需接受记忆测试，该测试模拟了交通状况及其他干扰因素对驾驶者脑力负荷的要求。传感器全程追踪记录了他们的视线轨迹、手指动作、瞳孔直径及皮肤电活动。

驾驶过程中，参与者需要在12英寸触控屏上点击特定目标，类似操作车载应用和小工具的场景。同时他们还需完成"N-back任务"的三个难度级别——这项记忆测试要求参与者在每隔2.5秒听到的数字序列中，准确复述特定数字。

研究发现，当驾驶者试图同时处理多项任务时，其驾驶表现和触屏操作能力均会下降：模拟车辆在车道内发生偏移，触屏操作的速度与准确性也明显降低。

"触控屏在现代汽车仪表盘中已十分普及，因此理解触屏交互如何影响驾驶者与驾驶行为至关重要。"论文共同资深作者、华盛顿大学信息学院教授雅各布·O·沃布洛克表示，"我们的研究率先从科学角度审视这一问题，为提升这类交互界面的安全性与有效性提供了新思路。"

《大众机械》杂志曾撰文指出，许多现代车载信息娱乐系统需要驾驶者耗费大量脑力并保持精确触控操作。

基于华盛顿大学与丰田的合作研究成果，科研人员建议未来车载触控系统可采用简易传感器——如眼球追踪装置或方向盘触觉传感器——来监测驾驶者的注意力与认知负荷。根据这些实时数据，车辆系统可动态调整触控界面，使重要控制功能更醒目、更便于安全操作。

Don’t take your eyes off the road to read new research from the University of Washington.
In partnership with Toyota Research Institute, UW researchers are exploring how modern touch screens in cars affect driving now that dashboard knobs and buttons are increasingly a thing of the past. The results could help auto manufacturers design safer, more responsive screens and in-car interfaces.
The team’s study, which was presented this fall at the ACM Symposium on User Interface Software and Technology in Busan, Korea, adds to what we already know about the dangers of distracted driving when it comes to phone use.
Participants driving a vehicle simulator and interacting with a touch screen (see video above) were given memory tests that mimic the mental effort demanded by traffic conditions and other distractions, the UW reported. Sensors tracked their gaze, finger movements, pupil diameter and electrodermal activity.
While driving, participants had to touch specific targets on a 12-inch touch screen, similar to how they would interact with apps and widgets. They did this while completing three levels of an “N-back task,” a memory test in which the participants hear a series of numbers, 2.5 seconds apart, and have to repeat specific digits.
Researchers found that when people try to multitask behind the wheel, their driving and their ability to use a touch screen both suffer. The simulator car drifted in its lane, and speed and accuracy using the screen declined while driving.
“Touch screens are widespread today in automobile dashboards, so it is vital to understand how interacting with touch screens affects drivers and driving,” said co-senior author Jacob O. Wobbrock, a UW professor in the Information School. “Our research is some of the first that scientifically examines this issue, suggesting ways for making these interfaces safer and more effective.”
Popular Mechanics wrote about the mental bandwidth and finger precision that many modern infotainment screens require in cars.
Based on the UW/Toyota findings, researchers suggest future in-car touch screen systems might use simple sensors in the car — eye tracking, or touch sensors on the steering wheel — to monitor drivers’ attention and cognitive load. Based on these readings, the car’s system might adjust the touch screen’s interface to make important controls more prominent and safer to access.
