Augmented Reality (AR) can enable new forms of self-expression and communication. However, little is known about how AR experiences should be designed to complement face-to-face communication. We present an initial set of insights derived from the iterative design of a mobile AR app called Wemoji. It enables people to emote or react to one another by spawning visual AR efects in a shared physical space. As an additional communication medium, it can help add volume and dimension to what is exchanged. We outline a design space for AR complementary communication systems, and ofer a set of insights from initial testing that points towards how AR can be used to enhance same-time same-place social interactions.

Digital communication is often brisk and automated. From auto-completed messages to "likes," research has shown that such lightweight interactions can affect perceptions of authenticity and closeness. On the other hand, effort in relationships can forge emotional bonds by conveying a sense of caring and is essential in building and maintaining relationships. To explore effortful communication, we designed and evaluated Auggie, an iOS app that encourages partners to create digitally handcrafted Augmented Reality (AR) experiences for each other. Auggie is centered around crafting a 3D character with photos, animated movements, drawings, and audio for someone else. We conducted a two-week-long field study with 30 participants (15 pairs), who used Auggie with their partners remotely. Our qualitative findings show that Auggie participants engaged in meaningful effort through the handcrafting process, and felt closer to their partners, although the tool may not be appropriate in all situations. We discuss design implications and future directions for systems that encourage effortful communication.
