Begin with lived friction: missed benefits because forms are confusing, surprise fees on water bills, or zoning notices nobody understands. Walk the routes, ride the bus lines, and shadow service counters. Each observation becomes a spatial anchor suggesting where an explainer should appear, gesture, or pause.
Design for people who hold authority and for those who feel ignored. A code inspector using a tablet on-site needs different overlays than a tenant with a cracked screen and prepaid data. Plan offline fallbacks, concise summaries, and respectful prompts that never assume background knowledge or institutional comfort.
Calibrate to cluttered kitchens, reflective glass, uneven alleys, and fluorescent hallways. Test tracking robustness on paper signage, textured brick, and winter coats. Use gentle motion, bold contrast, and steady anchors so explanations remain legible while people move, carry groceries, push strollers, or speak with staff under time pressure.
Take a carbon pricing law and stage it in a corner grocery: price tags shift, receipts itemize fees, and a delivery truck’s route updates. Users witness where money flows, who pays, and how rebates work, learning mechanics by watching familiar moments change around them.
Use doorframes as portals between past and proposed regulations, kitchen tables as anchors for benefit calculators, and bus shelters as timelines for appeals. These tangible touchpoints help people pace attention, return later, or compare pathways, keeping orientation steady while complexity unfolds at human speed.
Pair spoken explanations with tactile cues, simple diagrams, and optional sign language avatars. Offer vibration patterns for alerts and fixed-position captions that avoid neck strain. Provide text alternatives for every audio cue and descriptive audio for purely visual gestures, ensuring redundancy without overwhelming users in noisy, dim, or crowded environments.
Complex policy guidance must not require flagship hardware. Favor lightweight shaders, adaptive meshes, and prefetching on Wi‑Fi. Provide downloadable packs for offline use and fallbacks to 2D views when tracking fails. Make first-run setup painless, quick, and generous with storage controls, retries, and late consent prompts.
Avoid bureaucratic slang and translate with community reviewers rather than machine-only pipelines. Localize measurement units, dates, examples, and humor. Allow voice accents and dialect choices. Respect naming conventions and sensitive symbols, and give residents real control over labels so maps, benefits, and processes reflect lived realities.
