In 1993 I was the principal inventor of a text based learning and testing system using an options list or multiple choice questions wherein the actual answers to questions and/or their value were hidden (encrypted) in barcodes printed in a workbook or test paper.  Thus the scanning device could provide immediate feedback during learning and/or accumulated a test score as the student or candidate worked through the paper.  This allowed a student to be corrected and directed or their result to be known immediately a candidate completed a test; so that no special scanner or external/additional marking was required.

The system was used by a number of large organisations including Qantas, the Department of Defence, BHP and the University of Newcastle for testing up to 100 candidates at a time, before it became economically viable to give each candidate their own computer.  Barcodes were automatically generated by accompanying software I wrote that seamlessly merged them into the text of the authors' questionnaire or study booklets.  I also designed a custom 3of9 barcode font to facilitate this process.

Leon Dearden and I developed a barcode reader that decrypted and thus instantly scored the selected barcodes as they were chosen from a list, or multiple choice options, as scanned by a candidate/student.  Leon designed the prototype circuit for manufacture and programmed the firmware while I provided the program meta-instructions.  It was called SmartPen.  Each pen unit was networked back through a network controller to a single portable computer and printer.

The system was entirely catholic as to the actual test/work book being scored. The result was entirely determined by the work book or test and the student/candidates' responses.  It was theoretically possible that everyone in the room was simultaneously completing an entirely different test or lesson.

Test candidates were often given a printout of their result as they left the examination room.   In the case of abilities testing, that was designed by the University of Newcastle to test the aptitudes of candidates for apprenticeships, this printout provided a full abilities analysis against normalised results.

The invention reached the application stage to protect the IP and allow its public use but I decided not to proceed to a full patent as low cost computers were becoming available and a major investment was required to refine and further miniaturise the barcode reader for mass production and to redesign the networking solution.

I subsequently redesigned the reader software to work with any PC and any hand-held barcode scanner; making  the SmartPen device redundant.  But it is now very much a solution in search of a problem.

Laos

 

 

The Lao People's Democratic Republic is a communist country, like China to the North and Vietnam with which it shares its Eastern border. 

And like the bordering communist countries, the government has embraced limited private ownership and free market capitalism, in theory.  But there remain powerful vested interests, and residual pockets of political power, particularly in the agricultural sector, and corruption is a significant issue. 

During the past decade tourism has become an important source of income and is now generating around a third of the Nation's domestic product.  Tourism is centred on Luang Prabang and to a lesser extent the Plane of Jars and the capital, Vientiane.

Remembering 1967

 

 

 

 

 

 

 

1967 is in the news this week as it is 50 years since one of the few referendums, since the Federation of Australia in 1901, to successfully lead to an amendment to our Constitution.  In this case it was to remove references to 'aboriginal natives' and 'aboriginal people'.

It has been widely claimed that these changes enabled Aboriginal Australians to vote for the first time but this is nonsense. 

Yet it was ground breaking in other ways.

Energy Solutions

 

Most informed commentators agree that Australia needs a better mix of energy sources.  We are too dependent on fossil fuel.  This results in a very high rate of carbon dioxide production per capita; and this has international and domestic implications in the context of concerns about climate change.
