AR technologies for consumer market are nowadays mature for many applications. In the healthcare sector, as demonstrated by the increasing number of publications on AR for surgery, medicine, and rehabilitation, there is a great demand for solutions that improve current clinical practice. The aim of this special issue is to offer to engineers, computer scientists, and final users an overview of the real potentials of these technologies, based on a severe selection of papers, and to allow the development of useful products for the end users in the early future.

Inventive hardware and software ideas for this specific field of application are especially welcome. Papers describing new applications for a specific clinical problem preferably with results on humans are also of interest. Review papers focused on specific subtopics are particularly encouraged.

Potential topics include but are not limited to the following:

• New augmented reality applications for specific clinical problems preferably with results on humans
• Innovative augmented reality solutions for healthcare (surgery, rehabilitation, medicine, etc.)
• Inventive hardware and software augmented reality solutions for healthcare
• New augmented reality visualization and rendering modalities for diagnosis, intervention, and rehabilitation
• Recovering space perception in medical imaging through augmented reality visualization modalities
• Wearable displays for augmented reality guidance during manual tasks
• Tracking and registration solutions for augmented reality applications in healthcare
• Light field displays for medical applications
