The Evolution of Our Physical Relationships with Computation

A case study


The Abacus: Birth of Tactile Computation

Physical Mirroring

Moving beads on a frame mirrored cognitive processes, engaging the neocortex in a tangible way.

Touch vs. Thought

The abacus represented the first instance of tactile computation, bridging the gap between physical manipulation and mental calculation.


Cognitive Engagement

This tool laid the foundation for our physical relationship with computational devices.

The Slide Rule: Extension of the Human Hand

Watershed in Computation

The triple log KG slide rule marked a significant milestone in computational history

Direct Manipulation

Required active, continuous engagement through hand manipulation to perform calculations.

Intuitive Relationship

Fostered muscle memory, pattern recognition, and an intuitive understanding of numbers.


The IBM Selectric Typewriter: Mechanical Extension of Thought

Iconic Typeball

Revolutionary mechanism allowing unprecedented typing speed and accuracy.

Satisfying Physicality

Distinctive sound and mechanical response created a unique user experience. Very different experience to dictating to Siri.

Early Word Processing

Introduced MAG card memory, bridging mechanical and digital word processing.


The ENIAC: First Programmable Computer

Physical Labor

Required punching cards, pulling switches, and manually rewiring circuits.

Direct Intervention

Massive machine necessitated hands-on human interaction for operation.

Women in Computing

Majority of operators were women, pioneering the field of computer programming.


Blackberry Smartphones: The Pearl

Tactile Rewards

Satisfying clicks from the Qwerty keyboard created an addictive user experience.

Innovative Navigation

Introduced the trackball (pearl), revolutionizing mobile device interaction and introducing scrolling.

Full Control

Still had full control over mobile devices: Typed things manually


The Palm Pilot: Writing on Screen

Stylus Input

First handheld computer requiring a stylus for input, preserving the fluidity of handwriting.

Direct Screen Interaction

Allowed users to write directly on the screen, creating a unique connection with the device.

Personal Touch

Maintained individual personality in digital interactions through handwriting.


Wii Remote: Full-Body Computing

Motion Controls

Introduced motion-based controls, integrating full-body movements into computing.

Paradigm Shift

Marked a turning point, as future HCI pivoted from motion to neural interaction.

Dead End

Computing was moving more towards abstraction, not physicality.


The Xbox Controller: Enduring Physical Interface

Logitech G F710 Wireless Gamepad (Controller used for The Titan Submersible)

Enduring Physical

Interaction One of the most long-lasting physical relationships with a computing device.

HCI Standard

Set a physical interaction standard applied in other fields, such as drone control.

Ubiquitous Haptic Feedback

Pioneered the use of vibration feedback, enhancing the gaming experience.


iPhone 16: The Vanishing Touch

Removal of Physical Buttons

Shift towards gesture-based controls and AI automation.

Minimal Physical Interaction

AI-generated responses, eye tracking, and predictive automation reduce tactile engagement.

Audio Mimicry

Sound replaces touch, with audio feedback mimicking physical button presses.


50% Connected, 50% Disconnected: The Single Wireless Earbud

Blurred Boundaries

Users often don’t register whether they’re online or offline.

Subconscious Integration

Integrates the digital world into our subconscious experience.

Passive Interaction

Does not require active input, marking a shift in human-computer interaction.


Meta Glasses: Computing in Your Field of Vision

Minimal Physical

Interaction Relies on voice commands and subtle gestures.

Visual Integration

Exists in the user’s field of vision, blending digital and physical worlds.

Neocortex Engagement

Enhances interactions with our neocortex through visual and auditory stimuli.


Neuralink: The Future of Brain-Machine Interfaces

Direct Brain-Machine Interface

Eliminates the barrier between thought and action.

Cognitive Revolution

Fundamentally changes human cognition and interaction with technology.

Pure Neural Activity

Transitions from full-body engagement to purely neural interaction with computers.
