Tide Dial / Hardware & interaction

Fictional concept

Tide Dial

A little less screen.
A little more focus.

A desktop object that gives time a physical shape. One dial, an e-paper face, and a quiet ring of light turn a focus session into something you can set with your hands and leave at the edge of your attention.

01 / The idea

Give attention
an off-screen home.

Setting a timer on a phone starts with picking up a phone. Tide Dial explores a smaller ritual: choose a duration, press once, and get back to the work in front of you.

The proposed form is a palm-sized, weighted puck with a matte aluminum ring and a non-slip base. Its low profile keeps it visible beside a keyboard without becoming another dashboard.

02 / Three gestures

01

Turn to make time.

Rotate the outer ring to choose a session in five-minute steps. Gentle detents make the duration feel deliberate. The display shows one decision: how long to focus.

02

Press to begin.

Press the top surface to start or pause. A warm ring of light slowly recedes as the session progresses; the e-paper display updates once a minute to avoid a restless countdown.

03

Leave room for a break.

At the end, the light breathes gently. A second press starts a short break. There are no streaks, scores, or notifications competing for attention.

03 / Proposed architecture

Simple enough
to stay quiet.

An offline-first design with no account or companion app. A low-power microcontroller would handle timing, a rotary encoder would read the ring, and a diffused LED band would provide an ambient progress signal. USB-C would supply power.

Input

Rotary encoder + top-mounted switch

Output

Monochrome e-paper + dimmable LED ring

Enclosure

Aluminum ring + polymer base + silicone foot

Open questions

Display refresh artifacts, dial resistance, and light visibility in daylight

04 / Next experiment

Start with the feel.

The first prototype would test the interaction with a printed enclosure and an encoder: can someone set and start a session without instructions? Only then would it make sense to refine the display, light diffusion, and power budget. These are proposed validation steps, not completed tests.
