The wonderful world of vision

Earlier in the month, whilst attending an entire day's worth of seminars on 3-D imaging presented by the folks at Stemmer Imaging (Tongham, UK) our European correspondent overheard a couple of CEOs discussing the lack of talented young engineers who were entering the wonderful world of vision systems design.

As you might expect, the CEOs naturally felt that the low salaries offered by many of the Small to Medium Sized Enterprises that build vision systems for large OEM customers had a lot to do with it.

They believed that the first class engineering talent - in the UK at least - was still being attracted away from the engineering profession to enter less satisfying, yet ultimately more rewarding fields, such as investment banking.

While there may be some truth to that statement, I can't help but think that there's more to it than that. I think that the real problem is that manufacturers just haven't done much at all to make products that are affordable enough to allow children to experiment with hardware and software at an early age.

Well, I'm pleased to see that there are some folks out there who agree with me. More specifically, the folks at a Cambridge University (Cambridge, UK) based spinout called Raspberry Pi. The clever folks there have developed and are now selling a small $25 Arm (Cambridge, UK) based computer that into a TV and a keyboard and can be used by children (and interested adults!) as a means to learn programming.

The idea behind the tiny and cheap computer for kids came in 2006, when Eben Upton and his colleagues at the University of Cambridge’s Computer Laboratory (Cambridge, UK), including Rob Mullins, Jack Lang and Alan Mycroft, became concerned about the year-on-year decline in the numbers and skills levels of the A-Level students applying to read Computer Science in each academic year.

By 2008, processors designed for mobile devices were becoming more affordable, and powerful enough to deliver multimedia content, a feature the team felt would make the board desirable to kids who wouldn't initially be interested in a purely programming-oriented device.

Eben (now a chip architect at Broadcom), Rob, Jack and Alan, then teamed up with Pete Lomas at Norcott Technologies, and David Braben, co-author of the seminal BBC Micro game Elite, to form the Raspberry Pi Foundation, and the credit-card sized device was born.

This is a terrific idea and one which some of our esteemed colleagues who market both hardware and software for the vision systems business might like to consider emulating. What better way to encourage those young programmers to get hooked on vision systems design at an early age.
