  Short-form digital storytelling has become a popular medium for millions of
people to express themselves. Traditionally, this medium uses primarily 2D
media such as text (e.g., memes), images (e.g., Instagram), gifs (e.g., Giphy),
and videos (e.g., TikTok, Snapchat). To expand the modalities from 2D to 3D
media, we present SceneAR, a smartphone application for creating sequential
scene-based micro narratives in augmented reality (AR). What sets SceneAR apart
from prior work is the ability to share the scene-based stories as AR content
-- no longer limited to sharing images or videos, these narratives can now be
experienced in people's own physical environments. Additionally, SceneAR
affords users the ability to remix AR, empowering them to build-upon others'
creations collectively. We asked 18 people to use SceneAR in a 3-day study.
Based on user interviews, analysis of screen recordings, and the stories they
created, we extracted three themes. From those themes and the study overall, we
derived six strategies for designers interested in supporting short-form AR
narratives.
