Prototype study demonstrates a wearable ring interface providing wireless input and haptic feedback, suggesting viable screen-independent interaction across digital ecosystems.
SLoopRing is a wearable input-device concept designed to extend digital interaction beyond conventional screen-bound interfaces. The concept explores a compact, continuously accessible physical interface capable of transmitting user input wirelessly while providing haptic feedback to the wearer. Rather than replacing computers, smartphones or digital environments, SLoopRing is conceived as an additional interaction layer between the user and connected systems. Bluetooth provides a broadly compatible communication layer, while haptic feedback supports bidirectional interaction without requiring continuous visual attention. A 3D-printed physical form prototype has been produced to evaluate scale, wearability and basic physical characteristics. SLoopRing forms part of the broader EDeM ecosystem while remaining independently applicable across multiple digital environments and use cases. This publication describes the purpose, high-level design principles, development status and potential application scope of the concept. Implementation-specific mechanical architecture, control geometry, interaction mappings and selected ergonomic design decisions are intentionally excluded.
