Designing for a student who is blind requires a complete pivot from "visual" to "tactile and acoustic." In a middle school context, the game needs to be cognitively challenging while providing a high level of "haptic" (touch-based) feedback so the player can "see" the board with their hands.

♟️ ACCESS FM: Tactile Strategy Board Game

A - Aesthetics

• Texture Over Color: "Aesthetics" here means how the board feels. Use contrasting textures (e.g., smooth acrylic vs. rough 3D-printed carbon fiber) to represent different "colors" or teams.

• Symmetry: A symmetrical board layout helps a blind player build a mental map more quickly.

• Finishing: High-quality wood (sanded to a glass-like finish) with recessed Braille or tactile icons looks—and feels—sophisticated.

C - Cost

• Standard Braille Kits: Incorporating pre-made Braille beads or pins can be cheaper than 3D printing tiny Braille dots, which often require high-resolution resin printers to be legible.

• Material Waste: Use laser-cut scrap wood for the base and focus the budget on the 3D-printed pieces, which are the primary touch-points.

C - Customer

• Primary User: A blind middle school student.

• Skill Level: Middle schoolers are ready for complex logic. The game should move beyond simple "roll and move" to resource management or positioning.

• Social Play: The game should be "Universal Design"—meaning a sighted peer can play it without needing a separate set of rules.

E - Environment

• Desktop Stability: The board must have rubber feet. Since the player will be "scanning" the board with their hands, the board cannot slide or move during play.

• Quiet vs. Sound: Incorporate "acoustic feedback." For example, a piece that makes a specific "click" when moved into a valid slot helps the player confirm their move without needing to ask.

S - Size

• Hand Span: The board should be no larger than the student's comfortable reach (approx. $40\text{cm} \times 40\text{cm}$). If it's too big, they lose their "anchor point" (the edge of the board).

• Piece Height: 3D-printed pieces should vary in height. Taller pieces could represent more powerful units (like a Queen in chess), making them easy to find by sweeping the hand over the board.

S - Safety

• Filleted Edges: Every 3D-printed piece must have rounded (filleted) edges. Sharp corners are "noisy" to the touch and can be irritating during long play sessions.

• Magnet Safety: If using magnets to hold pieces in place, ensure they are deeply embedded and glued so they cannot be swallowed or pinched.

F - Function

• The "Grid Lock" System: Similar to Braille chess, white squares should be slightly raised and black squares slightly lowered.

• Peg and Hole: Every piece must have a peg at the bottom that fits into a hole in the board. This ensures that when the player "scans" the board with their palm, they don't accidentally knock the pieces over.

M - Materials

• Material Contrast: * Player 1: 3D-printed in a cold, heavy material (like metal-filled PLA).

  • Player 2: 3D-printed in a warm, light material (like wood-filled PLA or standard plastic).

• The Board: Laser-cut wood provides a natural "warmth" and a distinct sound when pieces are tapped against it.
