Interactive visualizations are external tools that can support users’ exploratory activities. Collaboration can bring benefits to the exploration of visual representations or visualizations. This research investigates the use of co-located collaborative visualizations in mobile devices, how users working with two different modes of interaction and view (Shared or Non-Shared) and how being placed at various position arrangements (Corner-to-Corner, Face-to-Face, and Side-by-Side) affect their knowledge acquisition, engagement level, and learning efficiency. A user study is conducted with 60 participants divided into 6 groups (2 modes \(\times\) 3 positions) using a tool that we developed to support the exploration of 3D visual structures in a collaborative manner. Our results show that the shared control and view version in the Side-by-Side position is the most favorable and can improve task efficiency. In this paper, we present the results and a set of recommendations that are derived from them.

交互式可视化是可以支持用户探索活动的外部工具。协作可以为视觉表示或可视化的探索带来好处。本研究调查了移动设备中协同定位协作可视化的使用、用户如何使用两种不同的交互和视图模式（共享或非共享）以及如何被放置在不同的位置安排（角落到角落、面对面）。面对面和并排）会影响他们的知识获取、参与水平和学习效率。使用我们开发的工具进行用户研究，将 60 名参与者分为 6 组（2 种模式\(\times\) 3 个位置），以支持以协作方式探索 3D 视觉结构。我们的结果表明，Side-by-Side 位置的共享控件和视图版本是最有利的，可以提高任务效率。在本文中，我们介绍了结果以及从中得出的一组建议。
