共享显示器上的多用户输入已被证明支持分组过程并提高性能。然而,目前用于教学协作任务的手势系统限制了对专家的输入,并且忽略了新手在共享显示器上进行参考的需求。在这篇文章中,我们研究了单用户手势工具在腹腔镜手术培训中对培训者和受训者之间交流的影响。通过对比使用手势工具和不使用手势工具的培训的交流结构和内容,我们发现当使用单用户手势工具时,交流变得更加不平衡,受训者的积极性降低。我们的发现强调了需要给予所有各方对共享显示的相同级别的访问,并在为教学协作任务设计共享显示方面提出了进一步的方向。
Multi-user input over a shared display has been shown to support group process and improve performance. However, current gesturing systems for instructional collaborative tasks limit the input to experts and overlook the needs of novices in making references on a shared display. In this paper, we investigate the effects of a single-user gesturing tool on the communication between trainer and trainees in a laparoscopic surgical training. By comparing the communication structure and content between the trainings with and without the gesturing tool, we show that the communication becomes more imbalanced and the trainees become less active when using the single-user gesturing tool. Our findings highlight the needs to grant all parties the same level of access to a shared display and suggest further directions in designing a shared display for instructional collaborative tasks.
