99% Invisible - Hidden Levels #2: Stick It to 'Em

Host: Roman Mars
Air Date: October 10, 2025
Theme: The evolution, design, and enduring influence of the joystick—from the earliest days of flight to game consoles, the military, and medicine.

Overview

This episode explores how the joystick—a simple yet powerful interface for human-machine connection—originated in early aviation, shaped the world of video games, and is now influencing everything from military technology to medical instruments. The episode also reflects on what makes the joystick’s design so intuitive and “joyful,” while questioning the rise of touchscreens as the dominant interface of our era.

Key Discussion Points and Insights

1. Konami Code: The Joystick’s Cultural Ubiquity

• [01:06]–[03:49]
  Roman Mars quizzes co-host Ben Brock Johnson about the legendary Konami code (up, up, down, down, left, right, left, right...), initially used in the 1986 game Gradius for power-ups and later immortalized in Contra.
  • “It’s this wink from gamer to gamer that you both know this piece of video game lore.” — Roman Mars [02:42]
  • Discussion reveals how joystick input patterns became both a cultural meme and a physical experience.

2. The Origins of the Joystick: From Flight to Play

• [04:22]–[08:54]
  Amory Sivertson recounts how early flight required intense bodily contortions to control aircraft—until 1907, when Robert Esnault-Pelterie patented the joystick, offering intuitive, one-handed control. The term’s origin is murky, but the “joy” refers to the thrill of control, not crude jokes about its between-the-legs position.
  • The joystick’s spread from aviation to arcade games, cranes, and even claw machines illustrates its foundational role in intuitive interface design.

3. Early Video Game Controllers and Their Evolution

• [09:04]–[12:55]
  David O’Grady of UCLA explains how early game controllers were side projects for engineers at companies working on military tech.

  • “It was a way to kind of use your downtime to develop something other than some kind of military application or a missile tracking system.” — David O’Grady [09:35]
  • Early home consoles like the Magnavox Odyssey used knobs—awkward, unintuitive—and early attempts at video game joysticks (e.g., Ralph Baer’s prototypes).

• [12:58]–[15:03]
  The Atari joystick (1977) marked the first mass adoption of a true joystick for home entertainment:

  • “This is kind of the first moment where the joystick becomes…something that all of us have access to.” — David O’Grady [10:58]
  • The Atari 2600 transformed TV play into a tactile, almost magical act of agency.

4. Why Joysticks “Feel Right”: Affordance and Intuition

• [12:31]–[14:30]
  • O’Grady introduces the idea of affordance—how an interface invites use. Joysticks map physical motion directly to in-game movement, making them feel “invisible” and almost telepathic.
    • “We want the interface to disappear. We want to look at where we're pointing, not at the hand that's doing the pointing.” — David O’Grady [13:34]
    • The “perceived affordance” of joysticks—“You see one, and you know exactly how to use it.” — Amory Sivertson [14:30]

5. A Visit to Joystick Wonderland: Tactile Lessons from the Past

• [15:03]–[17:53]
  Amory visits Jeff Boojack, owner of a vast retro game collection.
  • The Atari joystick is “stiff to the point where it hurts my wrist minutes into the game.” “Oh, it is rigid. I'm having a hard, like, it's not as responsive as I thought it would be.” — Amory Sivertson [17:38]
  • Despite discomfort, the Atari 2600 remains iconic (later humorously defended by Ben near episode’s end [42:33]).
  • Design evolution: Nintendo 64’s “thumbstick” enabled greater comfort, longer play, and more nuanced movement.

6. Two Sticks: Meeting the Demands of 3D Space

• [19:58]–[23:17]
  As games grew from 2D to 3D (GoldenEye 007, Medal of Honor), movement and camera needed to be split. The PlayStation DualShock controller (1997) perfected the two-analog-stick setup.
  • “Basically, one joystick is your eyes, the other your legs.” — Amory Sivertson [23:17]
  • Xbox and others would iterate, but the form factor has remained strikingly stable, proof of an optimal design.

7. Beyond Gaming: Joysticks in the Military and Medicine

• [29:04]–[35:25]
  Journalist Jared Keller details how modern military vehicles and weapon systems (e.g., the Air Force’s RADBO, Army’s Short Range Air Defense, and even drone systems in Ukraine) use controllers that mimic PlayStation and Xbox layouts.
  • “Gen Z and Gen Alpha…have grown up on these systems. So why waste time building a new one?” — Jared Keller [32:58]
  • The military benefits from intuitive, precise, and already-perfected private-sector designs.
  • The joystick also powers life-saving tools: endoscopic surgery performed across continents and bronchoscopy systems—now using Xbox-style controllers.

8. The Future: Joystick vs. Touchscreen and the Value of Tactility

• [37:04]–[41:26]
  The Finnish Museum of Games curators discuss the joystick’s tactile joy—and the shift to touchscreens, which lack “perceived affordance” and physical feedback.
  • “Touchscreens are scarily monolithic…a metaphor for the influence of big tech companies.” — Nikolas Nuland [38:50]
  • “You kind of become one with the joystick. And I think that's something that stays in people's muscle memory…we want to be able to be very precise.” — Miko Hinonen [41:00]
  • The episode ultimately defends the diversity of interface design: different tasks may call for different affordances.

Notable Quotes & Memorable Moments

• On the joy of intuitive control:
  “We want the interface to disappear. We want to look at where we're pointing, not at the hand that's doing the pointing.” — David O’Grady [13:34]

• On the physicality of the joystick:
  “You kind of become one with the joystick… we want to be able to sort of use our bodies for controlling…” — Miko Hinonen [41:00]

• On military tech adopting gaming controllers:
  “The military is basically saying, well, [gaming companies] did the job for us. Let's build these systems so that this next generation of warfighters can adapt those skills seamlessly to a military context.” — Jared Keller [34:14]

• On the tactile joy of joystick design:
  “The nail on the head—more like the thumb on the stick.” — Amory Sivertson [19:35]

• On the rise of touchscreens:
  “Touchscreens are scarily monolithic…everything is put into the same type of interface.” — Nikolas Nuland [38:50]

• On iconic, if uncomfortable, design:
  “This iconic device sucks. It's stiff to the point where it hurts my wrist...” — Amory Sivertson [17:41]
  Immediate lighthearted rebuttal from Ben Brock Johnson:
  “The Atari 2600 joystick is a beautiful piece of design...That is your problem, that is not Atari 2600’s problem.” [42:33]

Conclusion

“It’s about having the tool that affords what you need. Versatility, specificity, convenience, precision. It all depends on the game.” — Amory Sivertson [41:26]

The episode offers a rich meditation on how one humble stick—first designed to make flight easier—continues to influence technology, culture, and even our bodies. As touchscreens flatten our digital world, the joystick endures as a symbol (and tool) of embodied, intuitive human-machine connection.
