ARM4HanD2023 — Augmented Reality and Mixed Reality Applications for Handheld Devices.

Augmented and Mixed Reality (AR/MR) applications that extend the physical world with virtual components have been deemed a promising technology in various domains including education, healthcare, entertainment, and industry. Apart from special AR/MR head-mounted displays (HMDs), handheld displays (HHDs) such as smartphones and tablets offer a widely available and low budget access to AR/MR environments. Despite the huge potential assigned to these technologies, applications in the real world are still rare.

In the context of AR/MR-HHD applications, a major challenge concerns the design and development of suitable interaction techniques. In contrast to head-mounted displays, tablets and smartphones were originally not designed for spatial user interfaces but for 2D applications. For these 2D applications, touch-based input has proven to be very suitable and established as an intuitive input paradigm across many cultures and generations. In contrast, AR/MR-HHD applications require 3D input. To this end, previous research has proposed various interaction techniques including one-handed in-air gesture , advanced touch-inpu , or device-based input which maps the HHD’s position and orientation to virtual objecs. These existing interaction techniques however come with different drawbacks including fatigue, occlusion, inaccuracy, and low learnability. Hence, future research should focus on the following questions:

  • Which of these interaction techniques are suited best for which types of tasks and users?
  • Whether and how can the remaining problems of the different state of the art interaction approaches be improved?
  • Which of these interaction techniques are suited best for which types of tasks and users?

Another challenge is related to the small screen size of HHDs which restricts the user’s field of view in AR/MR applications. In this context, previous research has proposed different 3D visualizations for navigating to a point of interest that is currently out of view. While such visual cues can support navigation, they are also prone to visual clutter in more complex real-world settings. Hence, future work should deepen research toward appropriate navigation interfaces while considering the limited screen size. Like with HMDs, the application of HHDs will often include user physical actions like movement: hand-movements guided by vision: holding the display at a location that is interesting for MR; searching or traveling guided by knowledge or expectation: walking the HHD to a location where VR or AR is expected to enrich information / understanding / experience. During these actions, the HHD could or should provide supporting information.

Targeting the above-mentioned concerns and challenges, we envision that the research must address the need to bring AR/MR applications and technologies to the mass using the HHDs due to their availability and usage in daily life. The Workshop on Augmented Reality and Mixed Reality Applications for Handheld Devices (ARM4HanD 20223) will provide a platform for researchers, developers, and professionals to discuss issues and defining novel methods and approaches suitable for developing new interaction paradigms, user interfaces, 3D visualizations, and application for AR/MR in handheld display devices. Moreover, it will also be discussed how to make the real-time AR/MR applications more intuitive and usable so they can be used in different domains. Researchers and practitioners are invited to submit contributions including problem statements, technical solutions, experience reports, planned work and vision papers.

We intend to make ARM4HAND workshop as a regular event at INTERACT conferences in order to provide a permanent platform for researchers and practitioners in AR/MR, mobile, visualization, and the wide HCI community for discussing issues and presenting the breakthroughs in the field of AR/MR for handheld devices.
