To focus a clinical inter-vention, AR is not technically limited to introducing virtualelements into the physical world. It may also inhibit the per-ception of physical objects by overlaying them with virtualrepresentations, such as a virtual objects or even virtual emptyspaces—this reduces distractions (Milgram et al. 1994; Bausand Bouchard 2014)

The statement you provided discusses the use of Augmented Reality (AR) in clinical interventions. Here's a step-by-step breakdown:

1. AR is not only used to introduce virtual elements into the physical world: This means that AR technology is not just about adding virtual objects or elements to our real-world view. It has more applications than that in the context of clinical interventions.

2. AR may also inhibit the perception of physical objects by overlaying them with virtual representations: This means that AR can also be used to overlay physical objects in the real world with virtual ones. This can change or manipulate what we see in the real world.

3. Such as a virtual objects or even virtual empty spaces: This is an extension of the previous point, explaining that these virtual representations can be anything - from virtual objects to virtual empty spaces.

4. This reduces distractions: The purpose of this AR application is to reduce distractions. By overlaying physical objects with virtual ones, it can help individuals focus on specific things and ignore others, which can be particularly useful in a clinical setting.

5. The references (Milgram et al. 1994; Baus and Bouchard 2014) are likely studies or papers that provide more information or context about the use of AR in clinical interventions.
