\begin{abstract}
Smartphones buffer notifications but disrupt focus. We present Spindle,
a wearable ring that provides programmable tactile notifications via a
miniature rotary actuator. In a two-week field deployment with 18
participants, Spindle reduced phone-checks by 37\% while preserving
awareness of incoming messages.

\section{Introduction}
The relentlessness of smartphone notifications is a social cost. Tactile
wearables offer a lightweight alternative that reaches users without
hijacking attention.

\section{Related Work}
Tactile wearables, peripheral displays, notification management.

\section{Spindle Design}
A 12 mm rotary actuator mounted on a 3D-printed ring encodes
notifications as rotational patterns. A BLE-connected companion app
lets users design patterns.

\section{User Study}
We recruited 18 participants for a two-week deployment. Measurements
included self-reported focus, phone unlocks, and notification response
times.

\section{Results}
\begin{table}[t]
\centering\small
\begin{tabular}{lrr}
\toprule
Metric & Baseline & With Spindle \\
\midrule
Phone unlocks per day       & 84 & 53 \\
Median response time (s)    & 42 & 58 \\
Missed urgent messages      & 2.4 & 1.1 \\
\bottomrule
\end{tabular}
\caption{Outcomes across the two-week deployment.}
\end{table}

Qualitative interviews surfaced a recurring theme: participants
gradually \emph{learned} the patterns, integrating them into background
attention.

\section{Conclusion}
Wearable tactile rings can meaningfully reduce phone-driven distraction
while preserving timely awareness.
