The SVG pages have titles/descriptions and selectable text; the one-page PDFs are untagged and should not be the sole screen-reader route. Read the exact linear text below, use a school's accessible format, or invite a child to direct an adult. The coloured panels have dark outlines and text labels; colour never carries the answer. The diagrams are not actual size pads, material tests or vessel placements. For a tactile route, an adult can describe or offer approved large full-size clean material and a broad raised boundary only under local touch/hygiene/access approval; a no-touch spoken/AAC route gives the same design goal. Never use a small cutout, sharp edge or vessel as a surprise tactile object. No gate/result is preselected.
material-candidates.svg / material-candidates.pdf
Title: “Broad material candidates.” Subtitle: “Compare purposes, not guessed material properties.” Two side-by-side outlined candidate panels. Left BROAD CARD: a broad blank rectangle with a simple horizontal line; “A drawing, not an actual sample”; “Ask: suitable for which user?” Right CLEAN SOFT CLOTH: the same broad schematic rectangle and question. Bottom panel: UNKNOWN UNTIL APPROVED LOOK / TOUCH / TRY. “No sound, grip, allergy or strength result is supplied.” “A no-touch description and design route are complete.”
Linear prompt: “There are two drawn large candidate materials, broad card and clean soft cloth. Which might you explore for a named user? What would you need to ask or observe?” Tactile option: adult describes two actual approved full-size pieces, if available and wanted; record the actual source. The PDF does not show how either feels or sounds.
two-purpose-brief.svg / two-purpose-brief.pdf
Title: “Two purposes, two questions.” Top panel GENTLE CUE PAD: one drawn broad rectangle and a circle marking a possible cue place; “A willing partner may choose silence.” Question: “What did this person actually notice?” Bottom panel DRY LANDING PAD: two separate A/B circles above and apart from a rectangle labelled PAD IDEA · NOT TRIED; “Adult places empty A, then B.” Question: “Was each actual base wholly on the pad?” Footer: “One purpose does not prove the other. NO WATER.” These are diagrams; no listener, real pad or vessel is shown, and no base has landed on the drawn pad.
Linear prompt: “What information would a willing cue user give? What would an adult see for each dry base?” Tactile/no-print option: trace two large imaginary rectangles on a clear tabletop or describe them; no actual tap or container is required.
safe-pad-steps.svg / safe-pad-steps.pdf
Title: “Safe broad-pad steps.” Intro: “STOP for discomfort, unsuitable material or no approval.” Four large vertical numbered boxes, in this order: 1 ADULT CHECKS — “Clean broad material, allergies, access, clear dry table.” 2 CHOOSE A BROAD PAD — “Child proposes; adult prepares and approves real pieces.” 3 TRY ONE APPROVED ACTION — “Optional gentle cue OR adult places empty A then B.” 4 ASK AND RECORD — “Exact user response or each actual visible base position.” Final line: “No approved action? Write NOT TRIED; keep the design.”
Linear prompt: “Say the four steps. Who handles the object? What stops the action?” Tactile option: adult reads one whole large step card at a time; child reorders verbally, by pointing or AAC. These words do not authorize a physical try.
design-record.svg / design-record.pdf
Title: “Pad design and evidence record.” Four large blank panels with writing lines: USER / PURPOSE — “Who is this for? What do they need?” TWO IDEAS / CHOICE — “What differs? Why choose one first?” HANDLER / ACTUAL ACTION — “Who touched what? Cue or dry A/B separately?” USER / BASE / NEXT QUESTION — “Exact feedback or A and B position; what remains?” Intro: “Keep design, physical action and real response separate.” All fields are blank.
Linear prompt: ask each field in order and transcribe exact child words. Tactile/no-print option: four large spoken headings, with adult writing under each. If no approved trial, write NOT TRIED in the action/result field rather than inventing a response.
dry-vessel-brief.svg / dry-vessel-brief.pdf
Title: “Dry vessel design brief.” Two side-by-side invented outline panels: EMPTY A and EMPTY B, each a simple empty open container outline with a horizontal placeholder line. No dimensions or volumes are encoded. Intro: INVENTED OUTLINES · NO PAD OR PLACEMENT SHOWN. Bottom: NO WATER · adult handles real empty vessels; “For A and B separately: FULLY ON / EDGE OFF / NOT TRIED”; “Dry base position does not show capacity or stability.”
Linear prompt: “An adult would place approved real empty unbreakable A then B separately on a full-size broad pad. What visible base position would you need to see for each? If it did not happen, say NOT TRIED.” Tactile route can describe A/B outlines and a broad pad boundary verbally; no actual vessel handling is required.
local-source-slot.svg / local-source-slot.pdf
Title: “Real familiar source slot.” Four empty large provenance panels: APPROVED FAMILIAR SOURCE — “Which real product, service or environment?” DATE / PLACE / PERMISSION — “When, where, and who approved showing it?” CHILD-SEEN FEATURE — “What was actually noticed, not inferred?” PURPOSE / OPEN QUESTION — “Who designed it to help? What remains unknown?” Top instruction: “Leave blank without an actual school-approved source.”
Linear prompt: use only for a genuinely observed local familiar designed item. Child can dictate all four fields. Tactile route: adult describes the approved real item accurately if touching it is unsuitable; record that the child heard a description rather than saw/touched it. A fictional practice drawing never fills this provenance slot.
check-a-puppet-signal.svg / check-a-puppet-signal.pdf
Title: “Check A: Puppet Signal Pad.” Fresh fictional source panel: PUPPET SIGNAL PAD; “A willing partner wants an optional gentle turn cue”; “They may choose a visible sign instead of sound”; “No material, pad or user response is supplied.” Below: “Show TWO different broad-pad ideas; choose one for the user.” Two empty response rectangles labelled IDEA ONE and IDEA TWO. Bottom: “What would the willing user actually report? NOT TRIED is valid.” There is no gate/result or model answer in the response spaces.
Linear prompt: read the source once, allow an independent first idea in any communication mode, then collect before coaching. Tactile option: adult describes two blank large spaces and records the child's exact directed ideas without adding content. No real sound/touch trial is needed.
check-b-museum-vessel.svg / check-b-museum-vessel.pdf
Title: “Check B: Museum Vessel Pad.” Fresh fictional source panel: EMPTY EXHIBIT A / EMPTY EXHIBIT B; “Adult places empty unbreakable vessels separately”; “Design a broad DRY landing pad and findable labels”; NO WATER · no pad or result is supplied. Below: “Show TWO different pad ideas; choose one for this adult.” Two blank response rectangles labelled IDEA ONE and IDEA TWO. Bottom unselected status line: A and B: FULLY ON / EDGE OFF / NOT TRIED. No physical result is printed.
Linear prompt: child gives two designs, a user-linked choice, safe steps and separate actual/unknown A/B statuses. Tactile/no-print option: adult reads the two blank idea slots and unselected status choices. A drawn outline cannot establish base position, holding amount, water behavior or stability.
