Objective

To determine how ultrawide (UW) and dual displays configurations can influence neck biomechanics and performance compared to a single display.

Background

Studies have assessed neck kinematics and performance when using dual displays, but these studies have used screen sizes smaller than today’s display size, have inconsistent participant placement, and few have assessed these two variables together.

Methods

Seventeen participants completed five tasks on six display configurations. Neck kinematics and performance were tracked for each configuration.

Results

Centered configurations produced significantly different median neck rotation angles compared to secondary configurations (p < .001) for three of the tasks. A 34” curved UW display with a longer viewing distance produced similar neck kinematics to a single 24” display with the potential to also reduce screen interactions. When compared to single, the benefit of secondary versus centered monitors was dependent on the type of task being performed. Users may prefer the UW, centered dual, and secondary dual configurations over the single display.

Conclusion

The benefit of secondary versus centered displays is dependent on the type of task being performed. Dual displays are still beneficial but should be used with a monitor arm to switch between centered and secondary configurations as necessary. Future work should look at larger UW displays to see if these results hold compared to dual display configurations.

Application

The results can be used to make evidence-based guidelines for displays based on size and task. Researchers can use this information to design future studies looking at specific configurations.

检查常见计算机显示配置之间潜在的用户体验权衡

客观的

确定与单显示器相比，超宽 (UW) 和双显示器配置如何影响颈部生物力学和性能。

背景

研究评估了使用双显示器时的颈部运动学和性能，但这些研究使用的屏幕尺寸小于当今的显示器尺寸，参与者放置不一致，很少有人同时评估这两个变量。

方法

十七名参与者在六种显示配置上完成了五项任务。跟踪每种配置的颈部运动学和性能。

结果

对于其中三项任务，与次要配置 ( p < .001)相比，居中配置产生显着不同的颈部旋转角度中值。具有更长观看距离的 34 英寸弯曲 UW 显示器产生与单个 24 英寸显示器相似的颈部运动学，并有可能减少屏幕交互。与单一监视器相比，辅助监视器与集中监视器的优势取决于正在执行的任务类型。与单显示器相比，用户可能更喜欢 UW、居中双屏和辅助双屏配置。

结论

辅助显示与居中显示的优势取决于正在执行的任务类型。双显示器仍然有用，但应与显示器臂一起使用，以根据需要在居中和次要配置之间切换。未来的工作应该着眼于更大的 UW 显示器，看看这些结果与双显示器配置相比是否成立。

应用

结果可用于根据大小和任务为显示器制定基于证据的指南。研究人员可以使用这些信息来设计未来的研究，着眼于特定的配置。
