Recent Advances in Extended Reality

Dear Colleagues,

Recent technical advances and research in extended reality (XR), which broadly includes virtual, augmented, and mixed reality (VR, AR, and MR, respectively), enable us to extend our experience and abilities in various contexts. For example, VR users naturally and intuitively interact with remote users in immersive social virtual environments using their embodied avatars; AR users extend their sensory perception and knowledge through additional sensing devices equipped with AR displays; and in situ intelligent virtual entities are augmented into the real world.

In this Special Issue, we aim to capture the current states of XR research and developments while covering the interdisciplinary convergence research aspects in XR. We anticipate that this issue will address recent research findings and approaches, and possibly suggest future directions identifying research gaps. We are pleased to invite diverse research that covers different disciplines and perspectives, including, but not restricted to, the following topics:

• New XR frameworks and platforms;
• Sensing and tracking for XR;
• Novel interfaces and interaction design in XR;
• Security for XR;
• Usability and user experience (UX) studies;
• Human factors and ergonomics in XR;
• Perception and cognition in XR;
• Virtual avatars and agents;
• Human–robot interaction with XR;
• Remote collaboration and learning in XR;
• Context-aware XR systems;
• IoT and 5G for XR;
• Industrial and occupational XR applications;
• Other various XR applications.

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 250 words) can be sent to the Editorial Office for assessment.

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-anonymized peer-review process. A guide for authors and other relevant information for submission of manuscripts is available on the Instructions for Authors page. Electronics is an international peer-reviewed open access semimonthly 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 2400 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.
