Reducing the number of clicks is a misguided metric. A process with eight trivially easy clicks is better than one with two fraught, confusing decisions. Each decision burns cognitive energy and risks making the user feel stupid. The ultimate design goal should be to prevent users from having to think.

To test the interaction between physical buttons and the on-screen UI, the designer used a simple, reprogrammable keyboard from Etsy. The OS recognizes it as a standard keyboard, allowing for rapid, low-cost simulation of custom hardware controls directly within a Figma prototype.

Common frustrations, like chronically forgetting which stove knob controls which burner, are not personal failings. They are examples of poor design that lacks intuitive mapping. Users often internalize these issues as their own fault when the system itself is poorly designed.

The Wright brothers' first plane required a 'full-body activity' to fly, with hip movements controlling wing tilt and a lever for pitch—a system compared to 'patting your head and rubbing your stomach.' The invention of the single joystick radically simplified this complex, non-intuitive interface, consolidating multi-axis control into one hand.

To create a truly unique value proposition, the "Bored" team prioritized game mechanics that leveraged the combination of physical pieces and a digital surface. For example, one game uses the height (Z-axis) of stackable pieces, an interaction that cannot be replicated on a standard tablet.

The ultimate goal of interface design, exemplified by the joystick, is for the tool to 'disappear.' The user shouldn't think about the controller, but only their intention. This concept, known as 'affordance,' creates a seamless connection between thought and action, making the machine feel like an extension of the self.

A "frontier interface" is one where the interaction model is completely unknown. Historically, from light pens to cursors to multi-touch, the physical input mechanism has dictated the entire scope of what a computer can do. Brain-computer interfaces represent the next fundamental shift, moving beyond physical manipulation.

Products like a joystick possess strong "affordance"—their design inherently communicates how they should be used. This intuitive quality, where a user can just "grok" it, is a key principle of effective design often missing in modern interfaces like touchscreens, which require learned behavior.

For highly commoditized interactions like text editor undo or canvas pinch-to-zoom, users have powerful, ingrained expectations. Failing to match these conventions doesn't make a tool feel "different"; it makes it feel fundamentally unusable and broken, regardless of its other features. Innovation should be focused elsewhere.
