<b>The below research participant solicitation is being provided for
informational purposes only. The National Federation of the Blind has no
involvement in this research, but we believe that it may contribute to
our research mission.<br><br>
<br>
Purpose: </b>We are graduate students at the University of Delaware
working under Dr. Charles Dhong and are investigating how to overcome
tactile clutter in tactile graphics by using coatings, instead of the
typical route of only using different patterns or textures. <br><br>
We have two ongoing studies which we are hoping to recruit participants
for:<br><br>
<b>Study 1:</b> During the study, participants will be presented with
grids of texture where one square in that grid has a different texture.
The grids will vary in texture, size, and spacing. In the first task,
participants will seek out the varying texture swatch without any
material coatings. In the second, the varying texture swatch will have a
coating applied to the texture they are seeking to see if speed or
accuracy improves.<br><br>
The study is expected to take roughly 2 hours, although some participants
may take faster or slower than others. This includes time for as many
breaks as the participant wishes throughout the duration, and they are
always welcome to end their participation at any time. Participants will
still receive compensation even if they terminate their
participation.<br><br>
<b>Study 2: </b>During the study, participants will be presented with
challenge cards containing different shapes and textures. In each round,
they will be asked to locate and identify the matching shape or texture
on other cards. The study will be conducted both with and without
coatings. We will compare performance to see whether coatings improve
recognition.<br><br>
The study is expected to take roughly 1 hour, although some participants
may take faster or slower than others. <br><br>
Participants are welcome to as many breaks as they wish during the
duration of the studies, and are always welcome to end their
participation at any time. Participants will still receive compensation
even if they terminate their participation.<br><br>
<b>Eligibility: </b>Individuals who have low vision or blindness and have
exposure to high-school level mathematics. Participants may be excluded
if they have a history of neurological disorders (e.g., brain damage,
epilepsy, etc.). Anyone who has experienced severe injuries to fingers,
such as severe burns, may also be excluded. <br><br>
Individuals who are not 18 years of age or older additionally require
parental consent alongside their own. <br><br>
<b>Compensation: </b>We offer $20 Amazon gift cards to participants for
each task/study they participate in. <br><br>
For the studies described here, participants will receive $40 in Study 1
and $20 in Study 2. Participants are welcome to take part in one or both
studies. <br><br>
<b>Contact information if interested: </b>If interested in taking part in
one or both studies, please contact
<a href="mailto:dhonglabrecruitment@gmail.com" target="_blank">
dhonglabrecruitment@gmail.com</a>. We will answer the email to set up a
date, time, and location for the study. We can travel to a location
convenient for participants, or they can come to the university if
interested.<br><br>
These research studies have been reviewed and approved by the University
of Delaware Institutional Review Board (UD IRB), which is a committee
formally designated to approve, monitor, and review biomedical and
behavioral research involving humans.<br>
