 Tangibles are also used as proxies for manipulating \VOs, but can be inconsistent with the visual rendering, being haptically passives.

+Providing coherent visuo-haptic feedback to enhance direct hand perception and manipulation with \VOs in immersive \AR is challenging.
 While many wearable haptic devices have been developed and are capable of providing varied tactile feedback, few can be integrated or experimentally evaluated for direct hand interaction in \AR.
 Their haptic end-effector must be moved away from the inside of the hand so as not to interfere with the user interaction with the \RE.
 Different relocation strategies have been proposed for different parts of the hand, such as the nail, the index phalanges, or the wrist, but it remains unclear whether any of them are best suited for direct hand interaction in \AR.

 We first overview how the hand senses and acts on its environment to perceive and manipulate the haptic properties of real everyday objects.
 Second, we present how wearable haptic devices and renderings have been used to augment the haptic perception of roughness and hardness of real objects.
 Third, we introduce the principles and user experience of \AR, and overview the main interaction techniques used to manipulate virtual objects directly with the hand.
