Interaction with the physical environment and different users is essential to foster a collaborative experience. For this, we propose an interaction based on a central point represented by an Augmented Reality marker in which several users can capture the attention and interact with a virtual avatar. The interface provides different game modes, with various challenges, supporting a collaborative mobile interaction. The system fosters various group interactions with a virtual avatar and enables various tasks with playful and didactic components.

翻译：与物理环境和不同用户的互动对于培养协作经验至关重要。 为此,我们提议基于一个核心点的互动,即增强现实标记,让几个用户能够吸引关注,并与虚拟阿凡达互动。该界面提供不同的游戏模式,带来各种挑战,支持协作移动互动。这个系统促进与虚拟阿凡达的各种群体互动,并使得各种任务具有游戏性和实用性。
