Users

One person: the owner of the Windows PC, using their own iPad + Apple Pencil as a graphics tablet over the LAN. Two contexts, two surfaces:

  • At the iPad, mid-task, Pencil in hand, drawing into a Windows Ink app. They glance at the screen but their attention is on the stroke. One-handed reach only.
  • At the PC, setting up or monitoring: scanning the QR, picking a target display, watching that latency/drop stay healthy, releasing a stuck pen.

Product Purpose

Turn an iPad into a pressure- and tilt-aware pen for Windows with no native app: Safari captures Pencil samples, ships them over a WebRTC data channel, and the server injects them as synthetic Windows pen input. Success = the stroke feels direct (sub-30ms added latency), pressure visibly drives width, and nothing ever gets stuck down. The UI's job is to stay out of the way and make the invisible (latency, drops, contact state, injection health) legible at a glance.

Brand Personality

Instrument, not app. Precise, calm, quietly technical. Like lab equipment: it reports its own state honestly and never decorates. Three words: measured, exact, unobtrusive.

Anti-references

  • Consumer drawing-app chrome (skeuomorphic brushes, playful color, big rounded candy buttons).
  • SaaS dashboard tropes: hero-metric cards, gradient accents, marketing copy.
  • Anything that competes with the stroke for attention on the iPad surface.

Design Principles

  1. The signal is the only bright thing. One phosphor color carries the live ink, active state, and meters. Everything else is near-black and hairline.
  2. State you can trust at a glance. Connection, contact, latency, and drops are always visible and always honest. No hidden failure modes.
  3. Reach before reading. iPad controls sit where a thumb already is; the drawing surface is never blocked by chrome you didn't open.
  4. The tool disappears. Familiar controls, no invented affordances, no motion that doesn't report a state change.

Accessibility & Inclusion

Target WCAG AA contrast on all text and meters against the near-black surfaces. Honor prefers-reduced-motion (the phosphor decay and reticle pulse become static). Controls are real form elements, keyboard-reachable on the dashboard, and sized for touch (≥44px) on the iPad.
