“…In our ongoing work, we are also considering other scenarios (e.g., outdoor spaces, specialized medical or industrial settings, or a busy classroom), in which extreme or variable lighting, textureless, dark or reflective surfaces, or dynamic objects may be more common. Inspired by initial work on measuring spatial consistency and latency in multi-user scenarios [19,37], we are currently adapting the methodology described in this report to measure the localization accuracy and latency of holograms designed to persist across multiple sessions using spatial anchors [28]. Performance in this case is highly dependent on visual conditions and their consistency over multiple days, weeks or months, and we will obtain quantitative insights into the environmental properties which best support persistent AR content.…”

Markerless augmented reality (AR) has the potential to provide engaging experiences and improve outcomes across a wide variety of industries; the overlaying of virtual content, or holograms, onto a view of the real world without the need for predefined markers provides great convenience and flexibility. However, unwanted hologram movement frequently occurs in markerless smartphone AR due to challenging visual conditions or device movement, and resulting error in device pose tracking. We develop a method for measuring hologram positional errors on commercial smartphone markerless AR platforms, implement it as an open-source AR app, HoloMeasure, and use the app to conduct systematic quantitative characterizations of hologram stability across 6 different user actions, 3 different smartphone models, and over 200 different environments. Our study demonstrates significant levels of spatial instability in holograms in all but the simplest settings, and underscores the need for further enhancements to pose tracking algorithms for smartphone-based markerless AR.
