A Scoping Survey on Augmented Display Systems

Publication Info

• Topic area: Augmented displays combining AR and physical displays for productivity, analytics, and collaboration.
• Keywords: Augmented displays, AR integration, spatial frameworks, immersive analytics, collaborative systems, input modalities, virtual monitors, tabletop displays, large displays, multimodal interaction.

Background and Problem

• Problem / challenge: The field of augmented displays lacks a unified conceptual foundation, with fragmented terminology and limited systematic exploration of AR integration with physical displays.
• Significance: Augmented displays are increasingly used in real-world domains such as immersive analytics, computer-supported collaborative work, and multi-display environments, making a cohesive understanding critical for advancing design and deployment.
• Motivation and related work: Prior surveys have addressed related topics like collaborative AR, visualization beyond desktops, and multi-display environments but have not focused explicitly on augmented displays. This paper consolidates scattered research into a cohesive perspective.

Solution

• Proposed approach: The AR-Display Spatial Integration Framework, derived from a corpus of 62 papers, categorizes augmented display systems across four dimensions: extension type, AR content type, placement region, and spatial layout.
• Novelty:
  1. First scoping survey dedicated to augmented displays.
  2. Development of a four-dimensional framework to classify and analyze AD systems.
  3. Translation of corpus insights into practical design recommendations for AR-Display integration.
  4. Identification of research gaps and future directions in the AD domain.
• Procedure and key techniques:
  • Systematic snowballing review method to identify relevant papers.
  • Open coding to extract recurring design questions and dimensions.
  • Quantitative analysis of AR-Display configurations, input modalities, and placement strategies.
  • Practical recommendations based on framework mappings and corpus findings.

Results

• Concrete findings:
  • Discrete extensions dominate the corpus (67 systems), followed by continuous extensions (5 systems) and hybrid configurations (3 systems).
  • Common AR content types include virtual monitors, virtual canvases, 3D immersive visualizations, and GUI widgets.
  • Placement regions are categorized into border-region, front-region, surface-region, and behind-region, with layout strategies such as 2D grid, content-aligned, and parallel-aligned.
• Advantage over baselines:
  • Framework enables systematic categorization and comparison of AD systems, revealing design patterns and underexplored configurations.
  • Recommendations provide actionable guidance for integrating AR with physical displays across various domains and use cases.
• Experiments / evaluation:
  • Evaluation metrics include task accuracy, completion time, user position, head-gaze, and subjective measures like NASA-TLX and SUS.
  • Studies range from brief sessions (20–30 minutes) to longitudinal deployments (up to 14 weeks).
  • Controlled lab settings dominate, with limited real-world and in-the-wild evaluations.
• Limitations and future work:
  • Limited coverage of tabletop displays and heterogeneous multi-display environments.
  • Underexplored areas include continuous extensions, perpendicular-aligned layouts, and leveraging physical displays to mitigate AR limitations.
  • Need for standardized development and evaluation methodologies.

Summary

This paper introduces the AR-Display Spatial Integration Framework to systematically analyze augmented display systems, synthesizing insights from 62 papers. It categorizes systems by extension type, content type, placement, and layout, providing practical recommendations for design and integration. The survey highlights research gaps in areas like multi-display environments, continuous extensions, and adaptive AR configurations. By consolidating fragmented research, the paper aims to guide the development of next-generation AD systems that seamlessly integrate physical and virtual spaces.
