We demonstrate FlowRing, a ring-form-factor input device that enables interaction across a range of ad-hoc surfaces including desks, pants, palms and fingertips with seamless switching between them. This versatility supports systems that require both ...

Smart rings for subtle, reliable finger input offer an attractive path for ubiquitous interaction with wearable computing platforms. However, compared to ordinary rings worn for cultural or fashion reasons, smart rings are much bulkier and less ...

Missing data is a widespread problem in many domains, creating challenges in data analysis and decision making. Traditional techniques for dealing with missing data, such as excluding incomplete records or imputing simple estimates (e.g., mean), are ...

Algorithms for exchanging messages between subscribers are proposed based on the properties of finite associative-commutative rings with unity and Diophantine equations over such rings. Algorithms for constructing finite rings whose additive ...

TelemetRing is a batteryless and wireless ring-shaped keyboard that supports command and text entry in daily lives by detecting finger typing on various surfaces. The proposed inductive telemetry approach eliminates bulky batteries or capacitors from ...

Vibration is an efficient way of conveying information from a device to its user, and it is increasingly used for wrist or finger-worn devices such as smart rings. Unexpected vibrations or sounds from the environment may disrupt the perception of such ...

In this demo paper, we present a demonstrator for a ring-based finger tracking approach. The demonstrator consists of a ring-shaped interaction device, called PeriSense, utilizing capacitive sensing in order to enable finger tracking. The motion of the ...

In this paper, we study the self-stabilizing leader election (SSLE) problem in population protocols. We construct a non-deterministic population protocol that can solve SSLE on directed rings of all sizes. Our algorithm uses a constant number of states ...

Machine readable passive tags for tagging physical objects are ubiquitous today. We propose Motion Codes, a passive tagging mechanism that is based on the kinesthetic motion of the user's hand. Here, the tag comprises of a visual pattern that is ...

Smart-rings are ideal for subtle and always-available haptic notifications due to their direct contact with the skin. Previous researchers have highlighted the feasibility of haptic technology in smart-rings and their promise in delivering noticeable ...

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 ...

Smart rings have a unique form factor suitable for many applications, however, they offer little opportunity to provide the user with natural output. We propose passive kinesthetic force feedback as a novel output method for rotational input on smart ...

We present a design space for interaction with a ring, worn on the user's finger. Whilst prior work has studied the ring as a means of attachment for hand motion sensors, we investigate the interaction possibilities provided by the natural affordance of ...

We present FingOrbits, a wearable interaction technique using synchronized thumb movements. A thumb-mounted ring with an inertial measurement unit and a contact microphone are used to capture thumb movements when rubbing against the other fingers. ...

While many Android apps provide end-to-end encryption, the cryptographic keys are still stored on the device itself and can thus be stolen by exploiting vulnerabilities. External cryptographic hardware solves this issue, but is currently only used for ...

Smart rings are an emerging wearable technology particularly suitable for discrete notifications based on haptic cues. Previous work mostly focused on tactile actuators that stimulate only specific skin receptors on the finger, resulting in limited ...

We derive new, exact expressions for network centrality vectors associated with classical Watts--Strogatz style “ring plus shortcut” networks. We also derive easy-to-interpret approximations that are highly accurate in the large network limit. The ...

This paper explores experiences with ring and bracelet activity tracker form factors. During the first week of a 2-week field study participants (n=6) wore non-functional mock-ups of ring and bracelet wellness trackers, and provided feedback on their ...

In this paper, we introduce OctaRing, an octagon-shaped finger ring device that facilitates pressure-sensitive multi- touch gestures. To explore the feasibility of its prototype, we conducted an experiment and investigated users' sensorimotor skills in ...

The thumb has the unique property of being opposable to the other fingers and is thus used to perform specific tasks such as grasping objects, which cannot be done otherwise. In this paper we present an interactive ring that takes advantage of this ...
