Spatial Augmented Reality

Dear Colleagues,

Spatial augmented reality (SAR) seamlessly merges the real and virtual worlds by superimposing computer-generated graphics onto real surfaces using projectors. Unlike other types of AR, such as video see-through and optical see-through, SAR provides AR experiences of wide field-of-views (FOVs) for multiple users without requiring them to wear and/or hold any devices. Due to these advantages, it has been applied in many application fields, such as medical operations, industrial design, education, collaboration, various art and entertainment applications (such as art installation, game, theme park, and theatre), and so on.

In SAR, images are potentially projected onto non-planar, textured, deformable, and/or moving surfaces under environment light. There are several technical issues to display desired appearances on such non-optimized surfaces, which include static and dynamic geometric registration, radiometric compensation, defocus compensation, shadow removal, inter-reflection compensation, and so on. Projector–camera systems have been applied as a promising framework to solve these technical issues. Recently, computational display, the joint design of projector hardware, optics and computational algorithms, is an emerging technology that overcomes technical limitations of projector–camera systems to achieve high-quality projections, such as a high dynamic range, high speed, and super resolution. Another new research trend in SAR is hacking the human visual system to realize novel visual experiences. The rapid development of fundamental technologies has expanded the application scenarios and opened up new interdisciplinary research fields.

We encourage paper submissions on the following topics (but not limited to them)

• Projection mapping
• Projector-camera systems
• Static and dynamic geometric registration
• Geometric calibration including auto-calibration
• Radiometric compensation
• Inter-reflection compensation
• Defocus compensation
• Shadow removal
• Blending of overlapping projections in multi-projection system
• Computational display to overcome technical limitations of projection displays
• High dynamic range projection
• High speed projection
• Super-resolution projection
• Perceptual approach breaking physical limitations in projection displays
• Perceptions in SAR
• Applications of SAR

We encourage authors to submit original research articles, case studies, research, reviews, theoretical and critical perspective and viewpoint articles. Of particular interest are articles that explore new SAR techniques.

Manuscript Submission Information

Manuscripts should be submitted online at www.mdpi.com by registering and logging in to this website. Once you are registered, click here to go to the submission form. Manuscripts can be submitted until the deadline. All submissions that pass pre-check are peer-reviewed. Accepted papers will be published continuously in the journal (as soon as accepted) and will be listed together on the special issue website. Research articles, review articles as well as short communications are invited. For planned papers, a title and short abstract (about 100 words) can be sent to the Editorial Office for announcement on this website.

Submitted manuscripts should not have been published previously, nor be under consideration for publication elsewhere (except conference proceedings papers). All manuscripts are thoroughly refereed through a single-blind peer-review process. A guide for authors and other relevant information for submission of manuscripts is available on the Instructions for Authors page. Multimodal Technologies and Interaction is an international peer-reviewed open access monthly journal published by MDPI.

Please visit the Instructions for Authors page before submitting a manuscript. The Article Processing Charge (APC) for publication in this open access journal is 1600 CHF (Swiss Francs). Submitted papers should be well formatted and use good English. Authors may use MDPI's English editing service prior to publication or during author revisions.
