The Augmented Reality (AR) techniques for the buyer's industry are now established and suitable for multiple uses. As seen in the wellness sector, with more publications on the use of augmented reality in surgery, medicine, and rehabilitation, there is a high demand for solutions that can enhance clinical practice. This special issue aims to offer technicians, computer scientists, and users an overview of AR technologies' potential to develop beneficial applications shortly. It also aims to guide academic research toward overcoming technological and human-factor issues in current devices and popular modalities for enriching visual sensations with computer-generated elements. Six submissions have been accepted after being assessed by authorities in their academic fields. This special issue presents examples of medical treatment uses, spanning interactions between physicians and patients, surgery, rehabilitation, and fear treatments. Qin et al. demonstrate the possible uses of haptic feedback to enhance accessibility and natural interaction with computer-generated elements, even though AR apps and gadgets have primarily focused on enhancing the visual experience.
