We,
okay I, talk a lot how about difficult to design illumination, select
the right lens, and so on, but the HMI is usually left out of these
conversations. HMI, for those of you not “in the know” is the
acronym for Human Machine Interface, and it’s the fancy way of
saying “screen” or “monitor”.
It
seems to me any effective vision system should be conveying
information about what it’s doing. Not just inspection results but
perhaps some statistics and maybe something about the health of the
system. (There are probably many more things I could add to that list
if I took the time.)
Well
most of us engineers don’t think about HMI design, but judging by a
debate I’ve been following at the Automation World blog, “Engineers
Agree to Disagree on HMI Direction”
January 7th,
2014, we should.
It
might help you to read the editorial/opinion piece that started the
discussion: that was “HMIs
at an Inflection Point?”
(October 23rd,
2013).
How
do you think this relates to machine vision and vision systems? I’m
interested in your comments. Meanwhile, I’m off to watch football
on my 62 inch HMI.
