Help! I Need a Remote Guide in My Mixed Reality Collaborative Environment.

Area of Science:

• Human-Computer Interaction
• Collaborative Systems
• Virtual and Augmented Reality

Background:

• Remote expert assistance in maintenance tasks offers significant time and cost savings.
• Augmented reality (AR) and virtual reality (VR) technologies can improve remote guidance by overlaying 3D information and enabling shared virtual presence.
• Traditional face-to-face collaboration relies on rich interpersonal cues (e.g., gaze, body language) often missing in remote scenarios.

Purpose of the Study:

• To address the challenge of limited communication cues in remote mixed reality (MR) maintenance collaborations.
• To explore novel interaction paradigms that compensate for the lack of essential communication signals.
• To enhance collaborative abilities through shared viewpoints and improved awareness features.

Main Methods:

• Focus on the navigation task within maintenance procedures.
• Development of a novel interaction paradigm for demonstrating manipulation gestures.
• Implementation in an early prototype for evaluation.

Main Results:

• The study evaluates concepts for remote collaboration in MR environments.
• Identified opportunities for augmenting collaborative abilities, such as sharing identical viewpoints.
• Demonstrated a novel interaction paradigm for guiding manipulation tasks.

Conclusions:

• Effective remote MR collaboration requires adapted interaction and awareness features.
• Shared viewpoints and guided manipulation gestures are key to improving remote maintenance.
• Guidelines are provided for developing future efficient remote collaboration systems in MR.
