The Original Concept

Richard Baker conceived the original idea for an adaptive personalised instructional system while considering how a computer might perform functions normally undertaken by a human expert instructor. The objective was not merely to display stored information, but to obtain information concerning an individual, compare and evaluate that information against expert knowledge, determine what the individual needed, and automatically communicate personalised audio-visual instruction back to that person.

Learning About Emerging Technologies and Their Potential

After conceiving the original idea, Richard Baker began learning about computers, telecommunications, video and other emerging technologies, including through time spent at Bond University. The purpose was to better understand the technological world into which his idea might fit and whether the architecture he had conceived could ultimately be useful and practical.

As part of that learning, Baker encountered research literature discussing the need for greater interaction between computers and people. One issue concerned the imbalance between people providing instructions or requesting information from computers and what computers were capable of intelligently communicating back to people.

The developing "information superhighway" was sometimes described in terms of traffic heavily concentrated in one direction while the other direction remained comparatively empty. Baker recognised that the architecture he had conceived could contribute to that less-developed Computer-to-Human side of interaction.

For Baker, this period was fundamentally one of learning - understanding what computers and communications systems could and could not do, what researchers believed needed to develop, and where his newly conceived architecture might fit within that emerging technological future.

Concept Documented with Patent Attorney John Gardner

Contemporaneous correspondence records Baker's proposed Advanced Teaching Aid in considerable functional detail, including capture of a client's performance, selection of an expert or teacher, computer analysis against stored expert technique, identification of differences and return of personalised instructional material.

First Australian Provisional Patent Filing

The developing Advanced Teaching Aid concept entered the formal patent process. The later patent family records 30 May 1991 as the Australian priority date.

Telecommunications Feasibility Considered

Professor Rodney Tucker considered the practical telecommunications requirements associated with transmitting television or video information through communications networks. The correspondence illustrates the substantial bandwidth and technology limitations confronting the proposed system in the early 1990s.

International PCT Application Filed

PCT/AU92/00253 was filed, carrying forward the earlier Australian priority and developing the international patent family for the Personalized Instructional Aid.

United States Patent Proceedings

The invention proceeded through the United States patent system as U.S. Application Serial No. 08/146,016. This continued the patent development arising from the earlier Australian priority and international filing.

U.S. Patent No. 5,486,001 Issued

U.S. Patent No. 5,486,001, titled Personalized Instructional Aid, was granted. The patent established the principal U.S. documentary foundation for the personalised instructional architecture preserved within FINALSTEP.

Continuation-in-Part and Further Development

Baker continued developing the architecture through a U.S. Continuation-in-Part application addressing both remote and local implementations. The underlying instructional process remained central while the possible physical arrangements and technologies used to implement it continued to develop.

Technology Begins to Catch Up

Computing power, digital video, telecommunications and sensing technologies advanced rapidly. Functions that had been extremely difficult when the concept was conceived in 1990 became increasingly practical as computers became faster, digital video became easier to process, communications networks increased in capacity and new methods of sensing human movement emerged.

The architecture remained recognisable while the technologies capable of implementing its individual functions continued to evolve.

University of Queensland Research and Prototype Development

Research undertaken at the University of Queensland explored autonomous sports training using visual sensing and computer analysis. The work associated with Autonomous Sports Training from Visual Cues examined capture of an athlete's movement, comparison with an ideal movement and automated feedback, and expressly referenced Richard Baker's earlier patent family.

This represented an important stage in the progression from an architecture conceived when the necessary sensing, computing and communications technologies were far more limited toward increasingly practical automated sports instruction.

New Sensing Technologies Expand the Possibilities

Camera-based computer vision, motion tracking, inertial sensing and increasingly powerful processors created new ways for computers to obtain information about what a person was actually doing. Improved sensing could supply increasingly sophisticated performance information into the personalised instructional process.

Advances in sensing did not replace the architecture. They provided increasingly capable ways of supplying information into it.

Later Personalised Instruction and MEMS Development

Baker's later patent work addressed an important practical part of the process: obtaining better and more reliable information about the movement or performance of an individual, or an object controlled by that individual. The later development incorporated movement-sensing approaches including MEMS technologies and retained the objective of producing personalised audio-visual instruction.

More accurate sensing could provide better information for comparison and evaluation and therefore support more accurate personalised advice, coaching and feedback across a wider range of practical environments.

Motion-Based Interaction Reaches the Consumer Market

Motion-based interaction increasingly moved from specialist research environments into consumer products. Cameras, motion sensors, faster processors and improved software allowed computers and game consoles to obtain information about a person's physical movements and use that information during an interactive experience.

This represented a major change from the technological environment of 1990. Sensing a person's movement, however, remained only one part of Baker's broader architecture: information concerning the individual could be evaluated against relevant knowledge and used to determine and communicate personalised audio-visual information back to that person.

Microsoft Introduces Project Natal

Project Natal publicly demonstrated Microsoft's move toward camera-based full-body interaction without requiring the user to hold a conventional game controller. It was an important technological milestone in the emergence of practical mass-market movement sensing.

Personalised Interactive Training Reaches the Mass Market

During the Kinect era, motion sensing, computer processing and audio-visual presentation came together in consumer products on a scale that had not been practical when Baker conceived his architecture two decades earlier.

Products associated with companies including Microsoft, Ubisoft, Nintendo, Nike and others demonstrated how personalised interactive training was becoming a practical mass-market application rather than principally a research or specialist activity.

For FINALSTEP, this period is historically significant because capabilities relevant to the earlier personalised instructional architecture could now be seen operating within ordinary consumer environments.

Xbox 360 and Kinect Commercial Success

The introduction of Kinect coincided with a period of substantial commercial success for Microsoft's Xbox 360 platform. Contemporary market material preserved in the FINALSTEP archive records strong Xbox 360 sales and sustained leadership in the United States console market.

FINALSTEP preserves this material as historical context for the scale on which motion-based interactive products were distributed and used. The sales evidence does not, by itself, establish that Baker's patented technology caused that commercial success.

Baker Brings His Earlier Patent Work to Attention

As motion-controlled systems and personalised fitness applications entered the consumer market, Baker took steps to bring his earlier Personalized Instructional Aid patent work to the attention of relevant parties. Correspondence, delivery records, patent material and later USPTO records provide a documentary trail from this period.

Baker Patent Material Enters the Gesture Coach Prosecution Record

Material relating to Baker's earlier patent work was submitted into the USPTO prosecution record associated with Microsoft's Gesture Coach patent application. The cited Baker material included U.S. Patent No. 5,486,001, Australian Patent Application 19259/92 and international publication WO92/21412.

Gesture Coach Patent Prosecution Continues

The Gesture Coach application did not proceed directly to allowance. The prosecution history records rejection, applicant responses, further amendment and continued examination before the application eventually reached allowance. Baker's earlier patent material had been placed into the prosecution record while examination continued.

Gesture Coach Allowance and Recorded Consideration

The USPTO issued a Notice of Allowance for the Gesture Coach application on 12 December 2012. The citation record associated with Baker's earlier patent material later carries a January 2013 consideration date. FINALSTEP records these dates as they appear in the prosecution history without treating the chronology alone as proof of precisely when or how substantive consideration occurred.

U.S. Patent No. 5,486,001 Reaches Expiration

The original U.S. Personalized Instructional Aid patent reached the end of its patent term. Its expiration did not end the historical development of the architecture or Baker's later work on improved personalised instructional systems.

Patent Litigation

Baker commenced patent infringement proceedings concerning U.S. Patent No. 5,486,001 and later products and systems that he contended implemented the patented personalised instructional process.

The proceedings brought the technological history into a formal legal setting. FINALSTEP preserves Baker's infringement allegations as part of the litigation record; their inclusion records the position advanced by Baker rather than converting those allegations into judicial findings.

Preliminary Infringement Contentions

Baker filed his Disclosure of Asserted Claims and Preliminary Infringement Contentions, setting out where he contended elements of U.S. Patent No. 5,486,001 could be found within the accused instrumentalities. The contentions addressed literal infringement and Baker's asserted Doctrine of Equivalents and after-arising-technology positions.

Seattle Proceedings and Summary Judgment

The Microsoft-related proceedings were addressed in the Western District of Washington. The relevant infringement dispute was resolved at summary judgment rather than through a full trial on infringement.

Baker disagreed with the court's interpretation of his patent and maintained that the architecture, the patent specification, and relevant court rulings available at the time supported application of the patent to later-developed technologies and configurations.

Federal Circuit Appeal and Further Review

Baker appealed the district court decision to the United States Court of Appeals for the Federal Circuit. The Federal Circuit affirmed the district court's decision. Baker continued to challenge the interpretation applied to the patent and subsequently sought further rehearing and review.

Petition to the U.S. Supreme Court

Baker petitioned the Supreme Court of the United States for review, continuing to challenge the interpretation applied to U.S. Patent No. 5,486,001 and the resolution of the dispute at summary judgment.

FINALSTEP preserves both the judicial outcomes and Baker's position concerning those outcomes. The court decisions are part of the historical record, while the patent specification, prosecution history, infringement contentions, evidence and appellate arguments allow readers to examine why Baker continued to dispute the interpretation applied to his invention.

U.S. Patent No. 11,210,963 Granted

U.S. Patent No. 11,210,963, titled Method and apparatus for providing personalised audio-visual instruction, was granted to Richard John Baker. The later patent work developed improved ways of sensing movement and supplying performance information to the personalised instructional process while retaining the objective of automatically producing personalised audio-visual feedback appropriate to the individual.

In historical terms, the two generations of Baker's work can be viewed together: the earlier patent established the personalised instructional architecture, while the later MEMS-related work developed improved ways of sensing the individual and applying that architecture with greater accuracy across practical environments.

The Architecture in the AI Era

Artificial intelligence, computer vision, movement sensing, high-speed communications and increasingly powerful computing have transformed what computers are capable of doing when interacting with people.

In many modern applications, particularly interactive gaming, fitness, sports training and personalised coaching, the functional process can be strikingly similar to the architecture Baker was developing in 1990-1991. A camera or other sensing technology can obtain information about an individual's movement or performance; that information can be processed and compared with stored knowledge or an expert performance; the system can evaluate the differences; and personalised audio-visual information or advice can then be automatically generated and presented back to the individual.

Many modern systems therefore perform a functional sequence recognisable in Baker's early architecture: sense the individual, compare and evaluate against knowledge, determine what that individual needs, and automatically communicate personalised audio-visual information back to them.

The technologies performing those individual functions have changed enormously. The underlying architectural objective - enabling the computer to become more interactive on the Computer-to-Human side - remains remarkably familiar.
