I'm not sure it would be practical at the LinuxWorld conference --
especially given space considerations. Maybe for some other presentation,
but it's a matter of resources. I wrote an OVC check for $64 to Home Depot
for the materials -- and that was a stretch. If others want to take that on
as a project, I'm all for it.

We had a discussion about that on this list a few years ago. I think Karl
Auerbach won the debate for inkjet.

I've been doing demos up and down the state with Inkjet printers. They are
great for this, and can be battery powered. The h470b will run all day on
battery -- 400+ sheets is way more than any single voting machine would need
to do.

Furthermore, it might be that the inkjet technology will be much further
advanced in the next couple of years.

Go to this page and watch the video of the A4 printer:

"We plan to introduce components in 2008, enabling our customers to
introduce their first products in 2009." The timing seems good for a voting
system product that might get its first large scale use in 2010.

I'm not sure about your issues with ports and switches. I guess you mean
someone might still be able to get their fingers back there. The printer
(smart printer designed for election-dedicated duty) could butt up against
the back of the back panel -- flush or almost flush. I mean if someone is
hell-bent on damaging the system, they could bring a hammer. But I don't
see much problem preventing cheating.

The cable from the device to the screen should be embedded in the table top.
The power cable should be routed underneath to a power supply -- certainly
out of reach for the voter.

Ted Selker told me that touch screen capability could be added at no cost --
software only. That is, the technology used to put the pixels on the
display could also be used to detect a touch. We really do not need or want
color, if that helps keep the cost down. It doesn't seem like anyone is
making monochrome screens these days, however.

I'm looking for people that would be interested in partnering for the
display. So, I am interested in any meetings or discussions that could be
arranged.

I think a feasibility study could look at that. I will put that on the
scope of work we will be giving to LA Co. for a feasibility study. Set up
human trials comparing the various options.

Yes, something like Pvote. Have you seen that?

Not yet. I will also put out some notices soon. We are now in a real time
crunch for LinuxWorld.

I agree. I plan to contact some of them next week to get input for
LinuxWorld. As for a production system, this needs to be part of a
feasibility study.

Yes, but most know by now that paperless voting is on the way out. NIST and
the EAC talk about "Software Independence" (SI). Bottom line with SI is
that it means paper. The debate about paperless voting is just about over.

I don't mean to omit the ballot verification station. At LinuxWorld, the
ballot verification station (a bar code scanner mounted for hands-free
operation) may be part of the enhanced access voting booth -- given space
considerations. BTW, the bar code scanner I have (Richard Dawson has one
too -- a Symbol DS6708) can work in hands-free mode. In a production
system, the scanner might be at a point between the voting booths and the
ballot box.

Thanks.
