Dear Dr Bliss
These settings vary depending on font size, contrast/print quality and I also
sometimes turn it up more when it is cold.
Minimum useful intensity: 4______
The intensity you use most: 5-7______
Maximum useful intensity: even up to 10 if needs be______.
Kind regards
Susan

Optacon Users
I am working with a group at Zone 24X7 and SRI that has a National Science
Foundation (NSF) Small Business Innovation Research Grant (SBIR) to evaluate
the feasibility of a totally different technology in tactile displays. We
don't know to what extent this technology will be useful in a new Optacon, but
if it is, it has the potential of greatly reducing the cost of the Optacon
array. We are only at the beginning of this research and we would like your
help in determining the range of tactile stimulator intensity needed.
Imagine that the Optacon Intensity knob had a scale from 0 to 10, with 0 being
the current Optacon's minimum intensity and 10 being the maximum intensity.
Now estimate where along this scale you like to read with the
Optacon. If you set the knob half way between minimum and maximum, your
answer would be 5, if you set the knob 80% of the way from minimum to maximum,
your answer would be 8, and so on. Also it would be useful for us to know for
each of you what level is too intense, and what the minimum usable level is.
I would like to you to email your answer back to me to with these three
numbers:
Minimum useful intensity: ______
The intensity you use most: ______
Maximum useful intensity: ______.
I hope to get 50 or more responses from this listserv. I'll report the
results of this survey back to the listserv. Thanks for your help.
