Investigating interaction with a ring form factor

In this note, we study interaction with a finger worn ring, focusing on interaction enabled by the ring form factor. We report on 2 user studies, the first (n=13) investigating preferences for different interactions, whilst the second (n=7) explores usage contexts and applications. Twelve different ways of interacting with a ring were evaluated, including e.g. changing the placement of the ring on the fingers and moving the ring along or around a finger. Based the study results, the practical usability and concerns with each of the ring interactions is discussed. Whereas the concept was generally well received, the main concerns related to false positives, losing the ring e.g. when changing finger, and limitations from the rigid size of the form factor.
