Example: XYZ Reality (UK).

Disadvantages:

• Narrow viewing angle limits the field of view.
• No ability to make notes directly on the object.
• Gesture control only, which is inconvenient and limits functionality.
• Only one person can interact with the model at a time.
• The main disadvantage is that it is unsafe to use in construction conditions.

Examples: Trimble Connect AR (USA), Gamma AR (Spain), VGIS (Canada), Yijian AR (China), Vanjian BIMAR (China).

Advantages:

• A more flexible and accessible device compared to glasses.
• Convenient interface and user-friendly interaction format.

Disadvantages:

• Tablets only support augmented reality (AR) but not mixed reality (MR), which limits their ability to accurately visualize BIM models on the construction site.
• Tablets cannot effectively work with large BIM models due to the limitations of their graphics cards.

Advantages over competitors:

• We have developed a specialized device that allows working with large BIM models and supports both augmented and mixed reality.
• The device eliminates the key limitations of glasses and tablets, offering a safer and more efficient solution for construction sites.
