Using This Historical Reference Archive

The preceding documents have established the functional architecture underpinning adaptive personalised instructional technology.

The remainder of the archive moves into the documentary record.

It presents a chronological historical record compiled from patents, correspondence, legal proceedings, technical publications, product demonstrations, media reports, research material, and other contemporaneous documents collected over more than three decades.

Its purpose is to preserve the historical record and allow readers to evaluate the evidence for themselves.

Reading the Archive

Each document within this archive should be considered within its historical context.

Technologies evolved considerably after 1990, and many later commercial systems were not technically practical when the invention was conceived. Each record should therefore be read according to the knowledge, capabilities and circumstances existing when it was created.

Distinguishing Fact from Interpretation

Throughout this archive, every effort has been made to distinguish between:

• Documented historical facts, supported by original records.
• Technical analysis, explaining how particular systems function.
• Personal observations and opinions, clearly identified as interpretation where appropriate.

Readers are encouraged to examine the original evidence wherever possible and reach their own conclusions.

The objective of this archive is transparency rather than advocacy.

Looking Ahead

The documents that follow begin the chronological historical record, tracing the development of adaptive personalised instructional technology from its earliest conception through subsequent patents, technical developments, commercial implementations, litigation, and the emergence of modern artificial intelligence.

The Earliest Conception

The documentary record begins with Richard Baker's 1990 conception of a system capable of providing personalised audio-visual guidance based upon a person's current performance.

This concept became the foundation from which the subsequent patents, technical developments, and later historical events documented throughout this archive evolved.

The Practical Starting Point

Baker's wish to improve his golf swing led him to consider how he might receive the nearest practical equivalent of a lesson from expert golfer Tom Watson. His idea was to capture his own movement, send information representing that movement to a computer, and compare it with stored expert performance.

The Original Vision

The system would:

• capture the person's current performance;
• compare it with stored expert performance and knowledge;
• identify relevant differences;
• select stored expert audio advice; and
• automatically produce a personalised audio-visual presentation for viewing on a suitable monitor.

The available technologies imposed practical limitations, but the complete architecture had been conceived.

Technology Would Eventually Catch Up

High-speed networks were limited, affordable digital imaging was in its infancy, and the processing and sensing technologies available today had not emerged. Baker's historical position was that later advances improved the means of implementation without changing the central sequence of capture, comparison, evaluation and personalised response.

The Beginning of a Historical Journey

The documents that follow demonstrate how this original concept gradually intersected with emerging technologies over the following decades.

As computing power increased, sensing technologies matured, communication networks expanded, and artificial intelligence advanced, progressively more components of the original instructional architecture became technically achievable.

This historical progression forms the central narrative preserved throughout the remainder of this archive.

Looking Ahead

The next document examines the earliest documentary evidence supporting this original conception and begins tracing its progression into formal intellectual property protection and subsequent technological development.

From Concept to Patent

Having conceived the overall system in 1990, Baker's next objective was to secure formal intellectual-property protection.

This required the invention to be expressed in technical and legal language and the available components and implementation methods to be identified.

This process marked the beginning of the formal documentary record preserved throughout this archive.

Defining the Invention

Considerable work went into determining the best practical means available at the time to implement the system. The patent material described individual components as well as the functional relationships that joined them into one integrated process.

That technical disclosure has remained important as later technologies supplied new ways of performing particular functions.

The Integrated System

The patent material defined the available components and their functional relationship within the complete system. The system was intended to:

• Receive information representing the learner's current performance.
• Compare that information with stored instructional knowledge.
• Evaluate the learner's progress.
• Generate personalised instructional guidance.
• Repeat this process continuously as performance changed.

Viewed collectively, the components and functions formed the integrated instructional process disclosed in the patent material.

Beginning the Documentary Evidence

The following documents introduce the earliest patent records, supporting material, correspondence, and historical evidence relating to the original invention.

Together, they establish the documentary foundation from which the remainder of the archive develops.

Rather than presenting isolated historical events, these records reveal the continuing development of the invention across changing technological generations.

Looking Ahead

The next document begins the detailed examination of the earliest patent material and the historical circumstances surrounding the initial protection of the adaptive personalised instructional architecture.

The First Patent Application

The original conception of adaptive personalised instructional technology was followed by the preparation and filing of the first patent application.

This represented the transition from the original idea to a formally documented invention.

The patent application became the earliest official record describing the components and operation of a system for receiving a learner's current performance, comparing it with stored knowledge, evaluating the results, and providing personalised guidance.

The application therefore marks an important milestone in the historical record preserved throughout this archive.

Capturing the Complete Architecture

The application disclosed both the available technical components and their interaction within an integrated instructional system capable of providing adaptive personalised feedback.

The Technology of the Time

The technological environment in which the application was prepared differed substantially from that of today.

Personal computers were comparatively limited.

Digital communications were slow.

Affordable digital cameras and wearable sensing devices were not yet widely available.

Artificial intelligence remained largely experimental.

These practical limitations influenced how the invention could be implemented at that time, but the disclosed system was directed to providing personalised instructional guidance based upon a learner's current performance.

A Foundation for Future Development

The first patent application established the documentary foundation for the later developments discussed throughout this archive.

As technology evolved, new sensors, including MEMS devices, became available for capturing movement, while improvements in communications and processing enabled more advanced implementations of the architecture.

Historical Significance

The significance of the first patent application extends beyond the filing itself.

It provides a contemporaneous record of how adaptive personalised instructional technology was understood at that point in history.

As with every document reproduced within this archive, it should be considered within the technological context in which it was created.

Viewed in this way, the application forms the beginning of a continuous documentary history extending from the original conception through subsequent patents, commercial developments, litigation, and the emergence of modern artificial intelligence.

Looking Ahead

The next documents examine the contents of the earliest patent material in greater detail, together with the historical circumstances surrounding its prosecution and the technological developments that followed.
