About this Research Topic

Background

Virtual Reality (VR) has witnessed significant growth over the years. With advances in computer graphics, sensors/tracking technologies, and integrated circuit manufacturing techniques, VR became one of the vibrant emerging technologies in today's interactive computing. With continually evolving cutting-edge VR technologies, haptics becomes an integral part of bridging humans and VR experiences as a new dimension to VR. In addition, the emergence of wearable haptics, such as gloves, vests, and shoes, allows users to perceive realistic tactile and kinesthetic feedback that enhances the user experience and presence, engaging the users with real and virtual worlds.

Researchers have explored the feasibility of using new materials and technologies beyond the vibrotactile-based haptic actuators (e.g., ERM, LRA, piezo) to deliver more comfortable and natural VR interactions with richer haptic feedback. Smart materials like magnetorheological fluid showed a promising direction to adapt smart fluid into VR applications to create ground textures and deformation sensations for walking scenarios using haptics shoes. A soft tactile interface based on Electro-Active Polymer has been investigated to deliver different types of tactile stimuli in wearable and skin-attachable fashion. Microfabrication technology using an elastic form factor has been studied to provide high-fidelity haptic feedback. Finally, mid-air haptics technology has shown a great potential to deliver natural haptic feedback for free-form finger and hand interactions.

In this Research Topic, we seek innovative, next-generation haptics technologies and interfaces for VR and AR. We are particularly interested in emerging haptics technologies that incorporate new materials and technologies to provide enriched haptics and multi-sensory experiences in immersive environments. We welcome submissions of original research and reviews on the following topics:

- Advanced functional material-based haptic technologies for VR and AR
- Multimodal Interaction with new haptic actuators and interfaces
- Perception-based approaches and methods for novel haptics technologies
- Methods and applications of VR interaction using novel haptics technologies
- Data collection and haptic rendering using novel sensors and actuators
- Human-Computer Interaction involved in novel haptics technologies
- Use of haptic technologies in artistic settings (e.g., musical haptics)

Frequently asked questions

• What is a Research Topic?

  Frontiers' Research Topics are collaborative hubs built around an emerging theme.Defined, managed, and led by renowned researchers, they bring communities together around a shared area of interest to stimulate collaboration and innovation.

  Unlike section journals, which serve established specialty communities, Research Topics are pioneer hubs, responding to the evolving scientific landscape and catering to new communities.

• Why does Frontiers publish Research Topics? 

  The goal of Frontiers' publishing program is to empower research communities to actively steer the course of scientific publishing. Our program was implemented as a three-part unit with fixed field journals, flexible specialty sections, and dynamically emerging Research Topics, connecting communities of different sizes and maturity.

  Research Topics originate from the scientific community. Many of our Research Topics are suggested by existing editorial board members who have identified critical challenges or areas of interest in their field.

• Why are Research Topics important for journals?

  As an editor, Research Topics will help you build your journal, as well as your community, around emerging, cutting-edge research. As research trailblazers, Research Topics attract high-quality submissions from leading experts all over the world.

  A thriving Research Topic can potentially evolve into a new specialty section if there is sustained interest and a growing community around it.

• How do we ensure the quality of articles within Research Topics?

  Each Research Topic must be approved by the specialty chief editor, and it falls under the editorial oversight of our editorial boards, supported by our in-house research integrity team. The same standards and rigorous peer review processes apply to articles published as part of a Research Topic as for any other article we publish.

  In 2023, 80% of the Research Topics we published were edited or co-edited by our editorial board members, who are already familiar with their journal's scope, ethos, and publishing model. All other topics are guest edited by leaders in their field, each vetted and formally approved by the specialty chief editor.

• What are the benefits of publishing my article in a Research Topic?

  Publishing your article within a Research Topic with other related articles increases its discoverability and visibility, which can lead to more views, downloads, and citations. Research Topics grow dynamically as more published articles are added, causing frequent revisiting, and further visibility.

  As Research Topics are multidisciplinary, they are cross-listed in several fields and section journals – increasing your reach even more and giving you the chance to expand your network and collaborate with researchers in different fields, all focusing on expanding knowledge around the same important topic.

  Our larger Research Topics are also converted into ebooks and receive social media promotion from our digital marketing team.

   
• What types of articles can be published in a Research Topic?

  Frontiers offers multiple article types, but it will depend on the field and section journals in which the Research Topic will be featured. The available article types for a Research Topic will appear in the drop-down menu during the submission process.
