 They enable highly immersive \AEs that users can explore with a strong sense of the presence of the virtual content.
 However, without a direct and seamless interaction with the \VOs using the hands, the coherence of the \AE experience is compromised.
 In particular, there is a lack of mutual occlusion and interaction cues between the hands and virtual content when manipulating \VOs in \OST-\AR that could be mitigated by a visual rendering of the hand.
-A common alternative approach is to use real objects as tangible proxies for interaction with \VOs, but this raises concerns about their consistency with the visual rendering.
+A common alternative approach is to use real objects as a proxy for interaction with \VOs, but this raises concerns about their consistency with the visual rendering.
 In this context, the use of wearable haptic systems worn on the hand seems to be a promising solution both for improving direct hand manipulation of \VOs and for coherent visuo-haptic augmentation of touched real objects.
