Creating An Accessible Bartop Cabinet: Lessons from Sanibel’s Design Philosophy

Hook: You want a bartop everyone can play — not one that shuts people out

Too many bartop cabinets look incredible but are a pain to use if you have limited reach, fine-motor control, or need a caregiver's help. Shipping, restoration and part-sourcing are hard enough; accessibility shouldn’t add mystery. Inspired by the accessibility-first philosophy behind Sanibel — Elizabeth Hargrave’s 2025–2026 conversation-starting board game designed with her dad in mind — this guide walks you through practical, step-by-step upgrades to make your bartop truly inclusive.

The accessibility-first mindset: lessons from Sanibel

Sanibel’s design choices — big, tactile pieces, clear icons and interactions that don’t assume high dexterity — map perfectly to cabinet mods. Translate that intention into hardware by focusing on three player-centered questions:

• Can a player reach and operate controls easily from common positions (seated, standing, assisted)?
• Are the controls forgiving and obvious (larger targets, low actuation force, clear labels)?
• Does the cabinet support alternative input methods when a standard arcade layout is a barrier?

2026 trends shaping accessible bartop design

Late 2025 and early 2026 saw clear momentum in accessible gaming: more manufacturers released low-force buttons and optical joysticks, community modders shipped open-source reach-adjust templates, and indie tournaments began offering ADA-friendly booth setups with universal controllers. Expect to see more plug-and-play assistive gadgets in 2026: voice macros, phone-based control mapping, and low-latency Bluetooth switch interfaces that integrate with Raspberry Pi and modern arcade frontends.

Core upgrades overview — what we’ll cover

• Button spacing & sizing: make targets larger and easier to hit.
• Coin door alternatives: remove a common barrier to play.
• Adjustable heights: meet seated and standing use cases with simple mechanisms.
• Joystick & control ergonomics: low-force, short-throw options and placement tips.
• Alternative inputs: foot pedals, external switches, phone/voice integration.
• Wiring & maintenance: practical reliability and testing tips.

Project 1 — Re-spacing and upsizing buttons (step-by-step)

Why it matters

Small targets placed too close together force precise finger placement. For players with tremor, low dexterity, or those using adaptive aids, slightly larger buttons with more center-to-center spacing lower failed presses and frustration.

Design goals

• Button diameter: prefer larger buttons — aim for 35–45 mm (1.4–1.8 inches) where cabinet depth allows.
• Center-to-center spacing: 1.5–2.0 inches (38–50 mm) between adjacent buttons is a comfortable, inclusive range.
• Actuation force: choose low-force buttons where possible (look for buttons marketed as "light" or accessibility-friendly — operable without tight grasp).

Tools & parts

• Drill & template (download or print a grid matching your chosen spacing)
• Forstner bit or step bit sized for the button flange (check button spec)
• 35–45 mm buttons (Seimitsu/Sanwa-style or large US-style illuminated buttons)
• Quick-disconnect spade connectors or Molex terminals
• Zero Delay USB encoder or compatible wired input board

Step-by-step

1. Measure your control panel depth and available real estate. Draw the new layout, keeping main action buttons clustered but with the larger spacing. If space is tight, reduce rows or stagger buttons in an arc to preserve reach.
2. Print a drilling template at actual scale. Tape it to the panel and use a center punch to mark drill points.
3. Drill holes with the correct bit. Clean the edges and test-fit one button before completing all holes.
4. Wire each button to the encoder using labeled connectors. Keep wire lengths tidy and add a small loop for strain relief.
5. Mount tactile or high-contrast labels — Sanibel’s clarity-first approach means clear icons or bold text near each control.
6. Playtest with someone who has reduced fine motor control. Note accidental presses and adjust spacing or guard plates as needed.

Project 2 — Removing the coin-door barrier

Why replace coin mechs

Coin doors create physical and cognitive friction: keys, coins, and fiddly mechanisms. For home bartops and community spaces, a cashless, inclusive start system makes play instant and eliminates a common point of failure.

Accessible alternatives

• Large Start Button: a single oversized start button (50–60 mm) that requires little force.
• Token-mode / front-panel toggle: an internal toggle or remote that switches between free-play and locked modes.
• Tap-to-play: NFC or QR unlocks via phone that temporarily grant credits.
• Admin RFID / Bluetooth key: caregiver or host can give temporary access without fiddly coins.

Simple mod: oversized start + admin toggle (step-by-step)

1. Remove the coin mech and blank the opening with a metal plate or purpose-cut wood panel.
2. Install a large, low-force start button on the control panel front or a side-accessible faceplate. Position where seated players can reach without stretching.
3. Wire the start button to the encoder’s Start input. If you use a Raspberry Pi frontend, map that input to a virtual credit or Start action.
4. Inside the cabinet, install a keyed or rocker switch labeled FREE/LOCK for hosts. The switch simply shorts the coin input or toggles a digital input in your control software.
5. Optional: add an NFC reader wired to a microcontroller (e.g., Arduino/RPi). A small script can grant N seconds/minutes of play when a paired tag is presented.

Project 3 — Adjustable heights and reach-first layouts

Why height matters

Players might use the bartop standing, seated on a stool, or from a wheelchair. A single fixed height excludes several groups. Sanibel’s philosophy encourages designing for multiple postures — let players self-position the cabinet or provide quick, stable adjustment.

Target dimensions and quick rules

• Design for reachable controls between 15–48 inches (38–122 cm) above the finished floor for most operable parts. (Check ADA 2010 for exact specs applicable to public spaces.)
• Seated control-panel height: aim for 28–30 inches (71–76 cm) for comfortable seated play on common stools; lower if wheelchair clearance is required.
• Standing control-panel height: aim for 36–38 inches (91–97 cm).
• Allow at least 30 in x 48 in clear floor space in front for wheelchair users to approach and transfer when public or shared use is expected.

Mechanisms for adjustability

• Telescoping legs — simple, manual, lockable; easy to source or build with steel tubing.
• Scissor-lift brackets — fold flat for storage, good for moderate loads.
• Gas-spring hinges — allow smooth manual height changes with controlled resistance.
• Linear actuator — motorized, programmable heights, best for public/shared installations where hands-free adjustment is needed.

Step-by-step: retrofit telescoping legs

1. Measure current control-panel height and desired min/max. Pick telescoping legs rated for your cabinet weight plus a 25% safety margin.
2. Securely mount metal leg plates to the cabinet bottom. Reinforce the mounting area with a cross brace so the cabinet doesn’t torque when lifted.
3. Install leg collars with locking pins to hold discrete height positions (e.g., seated and standing presets).
4. Add rubber feet for slip resistance and to protect floors; test stability with an adult seated and leaning against the cabinet to verify no tipping.
5. Label height presets for quick adjustment — consider tactile bumps for low-vision users.

Joystick ergonomics: choosing the right stick and layout

Joystick choice affects reach, grip, and the force required to play. Accessibility-first picks prioritize low effort and predictable motion.

Recommendations

• Prefer optical or hall-effect joysticks for near-zero mechanical friction and long life.
• Choose short-throw units (reduced physical travel) and low spring tension for players with limited wrist range.
• Install a removable stick or side-mount option for players who use single-handed or adaptive grips.
• Place joysticks and main action buttons in a shallow arc to reduce shoulder rotation and wrist reach.

Alternative inputs & assistive features

An inclusive cabinet offers extra input channels. Use them with conditional software mapping so the same game can be played with different hardware.

Top alternative picks

• Foot pedals: map to Start/Jump/Fire for players who can kick more reliably than press buttons. (Good for public events and accessible demos — see how to host a retro arcade night suggestions.)
• Large external switches: push-on big-button panels mounted to the side or tabletop.
• Phone app / Bluetooth switch interface: let players pair their device to provide touch, tilt or big on-screen buttons.
• Voice macros: use a local offline recognizer to trigger non-time-critical actions like Start or Menu navigation (note latency and fairness in competitive play).

Software mapping: make the hardware useful

Hardware is only as useful as the software that understands it. Modern open-source frontends (Batocera, EmulationStation derivatives) allow input remapping per-game or per-profile. In 2026 you'll also find more frontends with built-in accessibility profiles for game speed adjustments, auto-fire toggles and simplified control schemes.

Best practices

• Create at least two profiles: Standard and Accessible. The latter should enable larger dead zones, toggle auto-fire, and map common actions to fewer buttons.
• Expose a quick profile-switch button on the control panel so a guest can switch modes in seconds.
• Document mappings with a laminated card on the cabinet for first-time users.

Wiring, reliability and safety

Inclusive cabinets must be reliable. A miswired large button that fails during a session is worse than none at all. Use these practical reliability tips from restoration practice.

• Use labeled, keyed connectors and color-coded wires. Label both ends.
• Install strain reliefs where cables exit the control panel and coin door area.
• Protect exposed metal edges and reinforce frequently used holes with grommets.
• Test each input in software with a multimeter or continuity tester and then with the frontend mapped before your first playtest.
• Keep a small accessible maintenance hatch or removable panel for quick changes without emptying the cabinet — consider field-friendly kits similar to portable event kits for your maintenance pack.

Case study: a community bartop remodel (real-world approach)

In 2025, a small makerspace converted a single bartop into a circulation unit for public events: they replaced clustered 30 mm buttons with 40 mm low-force buttons, added a foot-pedal Start, and installed telescoping legs to alternate between seated and standing demos. Key wins: more guests tried the machine (including three wheelchair users), game time increased per session, and maintenance calls dropped because the low-force buttons lasted longer and were less likely to be damaged. For groups looking to turn demos into recurring revenue, see the From Demos to Dollars playbook for tactics and monetization ideas.

Testing & iteration: the continuous improvement loop

Accessibility isn’t a one-off checkbox. After your mod:

1. Invite diverse testers — different heights, hand sizes, assistive-tool users.
2. Observe & note friction points: reach, label confusion, accidental presses.
3. Adjust spacing, swap button springs or add guard plates as needed.
4. Log changes and share a short README inside the cabinet describing what was changed and why — future owners will thank you.

Advanced strategies for 2026 and beyond

As assistive tech and community tools evolve, consider these advanced approaches:

• Adaptive firmware: microcontrollers that adjust debounce, sensitivity, and auto-repeat based on an accessibility profile selected by the player.
• Hybrid tactile & audio cues: small haptic transducers and optional audio prompts to support multi-sensory feedback for low-vision players; don’t forget lighting and shelf accents — affordable DIY lighting kits can help prototype cues quickly.
• Cloud-synced profiles: players can log in with an RFID or phone and load their custom control mapping instantly (gaining traction in community venues in early 2026).
• Open templates: shareable drill guides and CAD models — the 2026 maker scene favors contributor-driven templates for reach-adjustable panels and standardized mounting points; see efforts to centralize these resources at indexing manuals for the edge era.

Accessibility checklist — quick reference

• Controls within 15–48 in vertical reach band; clear floor space in front (30x48 in if public/shared)
• Main action buttons: 35–45 mm diameter, 1.5–2.0 in center spacing
• Low-actuation buttons where possible; optical joysticks or hall sensors for low friction
• Coinless start options: large start button + admin toggle or phone/NFC unlock
• Adjustability: telescoping legs or gas-spring hinge with clear presets (telescoping leg plans and sourcing are common in micro-events and pop-up playbooks)
• Alternate inputs available: foot pedals, external big-switches, phone pairing
• Clearly labeled profiles and a visible instruction card

Final takeaways

Sanibel reminds us accessibility is not a gimmick — it’s a design value that makes play inclusive and enjoyable for more people. On a bartop, small ergonomic changes compound into a radically different experience: larger buttons, smarter spacing, coinless entry and height adjustability convert a niche showpiece into a shared social object.
