Super Angry Birds – A Tangible Controller

In 2012, Angry Birds was already a global reflex: pinch, pull, release, watch physics punish a pig fortress. What it lacked on a laptop was the body memory of a real slingshot—the growing resistance in the hand, the sudden empty release, the sense that aim lived in the wrist as much as on a glass screen. Super Angry Birds, a force-feedback USB controller by Hideaki Matsui and Andrew Spitz, tried to put that missing physical metaphor back into the game.

Built as a student project at the Copenhagen Institute of Interaction Design (CIID), the device is not a novelty plastic sling with a hope and a prayer. It is a carefully staged piece of haptic design: wood, a hacked studio fader, an Arduino-class brain, and software that maps pull distance to opposing force. Press coverage from Engadget, Gizmodo, Designboom, and New Atlas treated it as more than a meme accessory. It was a clean demonstration of how tangible interfaces can make a familiar digital action feel newly legible.

A haptics class with a very public mascot

Matsui and Spitz developed Super Angry Birds in CIID’s haptics course led by Bill Verplank and David Gauthier—names that matter in interaction design because Verplank’s lineage connects to decades of thinking about how force, gesture, and feedback should feel, not merely look. The assignment context explains the project’s seriousness. This was not “make something viral with birds on it.” It was “make force feedback meaningful,” using a game millions of people already understood in their fingers.

Angry Birds was an ideal target. The core loop is a single continuous gesture: draw back, aim, release, optionally trigger a special ability mid-flight. Those verbs map cleanly onto physical controls. Pull becomes a slider. Angle becomes a pivot. Special power becomes a discrete trigger. When a game already thinks like a tool, a tangible controller stops being a costume and starts being an instrument.

The pair documented the work with a polished demo film—widely shared via Vimeo and YouTube mirrors—that shows the wooden sling, the resistance in the pull, and the small TNT-style plunger used to fire bird abilities. The finish looks almost retail. That polish is part of why the project traveled so far beyond the classroom: it photographed and videoed like a product even though it was never meant for store shelves.

The secret ingredient: a motorized mixer fader

The clever hardware move was to hack a motorized fader of the kind found in audio mixing consoles. In a studio desk, those faders can be driven by motors so automation can move levels for you. Matsui and Spitz inverted the idea. Instead of the computer moving the fader for playback, the motor pushes back against the player’s hand to simulate elastic tension.

Their force model was explicit. They drew a force curve, stored values in a table, then used the slider’s current position as an index: look up the force for that distance, send it to the motor, feel the opposing pull. As you draw farther, resistance grows in a way that reads as slingshot physics rather than as a sticky linear pot. Release, and the mechanism can snap forward—empty hand, bird gone, pigs in trouble.

That lookup-table approach is elegantly old-school and very teachable. You do not need a full physics engine in the controller. You need a believable mapping between position and force, tuned until the gesture matches what players already expect from the on-screen rubber band. Haptics succeeds when the brain stops analyzing the trick and starts aiming.

Music & Motors, Max/MSP, and Arduino

On the control side, the team programmed in Max/MSP and Arduino. Hardware duties ran through Music & Motors, an Arduino-based microcontroller developed at CIID for projects that mix sensing, actuation, and creative coding. That stack is typical of interaction-design labs of the era: Max for rapid mapping and performance-style patching, Arduino-class boards for motors and sensors, USB out to the host machine running the game.

Functionally, the controller exposed the game’s full control set. You could manage pull strength, adjust launch angle by pivoting the wooden sling assembly, and trigger special bird powers with the TNT box plunger. Angle sensing plus force feedback is what separates this from a one-axis novelty slider. Aiming Angry Birds is a two-part decision—how far and which way—and the hardware respects both.

Demonstrations focused on the original Angry Birds on PC. Commentators noted the obvious adaptation limits: sequels with different gestures, or Angry Birds Space with its orbital weirdness, would need different kinematics. The point of the project was never universal gamepad replacement. It was proof that one beloved gesture could be rebuilt in wood and wire until it felt inevitable.

Why “tangible” mattered in the Angry Birds era

By 2012, touchscreens had trained a generation to treat physics puzzles as fingertip theater. That was liberating and also strangely disembodied. Super Angry Birds arrived in a wave of DIY and lab controllers that tried to re-physicalize hit mobile games—giant foam slingshots, cardboard rigs, Kinect experiments. Most were jokes with good lighting. Matsui and Spitz’s version stood out because the resistance was real, tuned, and explained.

Tangible interaction research has long argued that cognition is not trapped behind glass. When force tells you how far you have pulled, you offload some of the work from eyes to muscles. You can aim while watching the pigs, not the rubber band UI. That is a small quality-of-life change and a large design lesson: feedback channels should match the metaphor. A slingshot that does not push back is only a picture of a slingshot.

There is also humor in the craft. A motorized audio fader—an object from serious studio work—ends up flinging cartoon birds. Music hardware becomes game feel. That crossover is classic CIID energy: borrow from adjacent technical cultures, hide the borrow inside a friendly form, let the demo video do the rest.

Not a product—and better for it

Pocket Gamer, Engadget, and others were clear: this was unlikely to appear in shops. No SKU, no Rovio partnership announcement, no Kickstarter in the coverage trail. For a haptics class project, that absence is a feature. Commercial constraints would have forced cheaper actuators, safety certifications, and a plastic shell that photographed worse and felt less considered. As a one-off, Super Angry Birds could stay honest about materials and intent.

What circulated instead was the idea. Design blogs treated the force-curve explanation as reusable knowledge. Angry Birds fans treated the TNT plunger as delightful fan service. Interaction students got a case study in matching input device to game verb. Years later, the project still reads cleanly because the problem statement is timeless: digital actions often imply physical forces that screens cannot deliver alone.

If you play the demo film today, notice how little the interface needs to shout. The wood looks calm. The motion is one gesture. The joke—Angry Birds with a real pull—lands because the engineering is quiet enough to disappear. That is what a tangible controller should do. It should not remind you that you are holding a project. It should remind you that you are holding a slingshot, and that the pigs should be worried.
