Alexis Scott-Morrison, Alice Miller, Allan Eustis, David Baquis (U.S.
Access Board), David Flater, John Wack, Sharon Laskowski, Tricia Mason,
meeting presentations are being worked on and will be available by COB
today. They will be publicly available on Monday morning 5/23.
There will be a reception on Sunday afternoon at 6:00 p.m. (Whitney
encourages anyone available to attend as this could serve as a pre-briefing
to the plenary meeting.) Copies of the current VVSG will be made available
by Allan on Sunday night.
Wack went over the agenda for the plenary meeting. Highlights include
a brief introductory by Commissioner Davidson, with Brian Hancock discussing
some Best Practices. John will be talking about the editing of the VVSG
and the next steps in finishing the report. Subcommittee presentations
will start with CRT, then HFP, finished by STS. Day 2 will consist of
planning next steps in the process.
subcommittee telecons have been submitted to the federal register -
plans are to continue on same days as has been the case.
- Dr. Jeffrey
testified at an EAC hearing on May 17, his testimony is available at
vote.nist.gov. When asked about July deliverable, Dr. Jeffrey was confident
of meeting the deadline.
- Two slots
on the TGDC are vacant.
Presentation (Sharon Laskowski):
everyone the draft presentation before the meeting. This subcommittee
meeting was devoted to review of that presentation:
working on the benchmark slides, they are not included in the draft
- The purpose
of this presentation is to go over what has changed since the last plenary;
to summarize significant changes since the VVSG 2005; and to give a
progress report on the usability benchmarks.
- One major
issue to be noted for meeting: HFP has reworded the accessible voter
verification requirement as agreed upon at the last plenary. Exact wording
was submitted as a resolution, but there shouldn't be any problem with
the modifications made. Changes have been run by STS.
then proceeded to go through each slide and request comments to the
presentation. The following are notable points:
5 (Added Cast Ballot Notifications) - Sharon will change wording
on slide to reflect CRT's changes in requirement.
8 (Moved VVPAT Requirements to VVPAT Section) - Our requirement
was removed and added to the VVPAT section. It has been simplified
to be less specific. Committee discussed whether to word it as screen
comparison of record vs. verification. It was decided to be a comparison.
Slide 10 (Proposed New Wording for Low Vision on Paper Records)
- This is new wording that has not yet been reflected in the current
draft of the VVSG.
Slide 11 (Accidental Ballot Activation) - This is a shall requirement
that calls to minimize accidental ballot activation errors, making
this requirement hard to test. This does not apply to errors caused
by voters intentionally casting ballots then changing their minds.
Slide 12 (Rewrite of Accessibility Subsection) - Change requested
to slide to reflect that we are talking about systems designed for
the general population.
Slide 14 (Rewording of Accessibility for Voter Verification) - This
requirement was changed from previous TGDC approval to be more general.
It has been circulated to STS. This is being called out special
so that the committee realizes this is a change to the wording approved
at last plenary. There is no need for an amended resolution as long
as HFP chapter is approved in whole.
Benchmarking vu-graphs - not yet prepared. Sharon will include vu-graphs
that cover results of the testing that was complete on May 17. Validity
of errors and repeatability/reliability has been received. She will
include testing suggestions on how to use benchmarks. After June
1, it will be possible to set benchmarks for a variety of systems.
Timing results will be discussed - even if this is not a usability
metric it may be taken into account when purchasing systems. Sharon
will discuss the satisfaction response, there was no repeatability
except in respect to confidence, this is a usability benchmark we
would like. Sharon will also provide a timeline for completing the
benchmarks section of the HFP chapter.
adjourned at 11:50 a.m.
to the Help America Vote Act of 2002, the TGDC is charged with directing
NIST in performing voting systems research so that the TGDC can fulfill
its role of recommending technical standards for voting equipment to the
EAC. This teleconference discussion serves the purposes of the HFP subcommittee
of the TGDC to direct NIST staff and coordinate its voting-related research
relevant to the VVSG 2007. Discussions on this telecon are preliminary
and do not necessarily reflect the views of NIST or the TGDC.]
