Volunteers Requested - Computer Graphics Study on the perception of geometric arrangements

Department of Computer Science, University of Waterloo



My name is Zainab AlMeraj. I am a PhD student at Computer Graphics Lab in
the School of Computer Science. I am working under the supervision of
Professor Craig S. Kaplan.

We are seeking research participants for a study that involves one session
lasting between 45 and 60 minutes.

During the session you will be asked to complete two tasks. The first task
involves sorting a number of arrangements on small cards into a number of
piles. The arrangements are composed of four sets. For each set there is a
sample image and eleven larger samples. You will be asked to pile the
images according to your own criteria. The piles you make will be recorded
for reference and analysis.

The second task involves a comparison task in which you choose one of two
images of different sets of arrangements using a mouse and a computer

All your information and data will remain confidential.

In appreciation for your time you will receive a Tim Hortons gift
certificate worth $15.

Participants who have previously completed an earlier phase of this work
are requested not to contact or take part in this phase of the study. Your
understanding to this matter is much appreciated.

This study was reviewed and received ethics clearance through the Office
of Research Ethics.
For more information about this study, or to volunteer for this study
please contact:

Enrollment caps have been restored for CS courses

As per the course selection policy, enrollment caps for all CS courses have been returned to their actual class size. If the class or section is full then it means that you will need to wait for another student to drop it. You have until 11.59 p.m. on Monday May 14 to add courses.

The following courses still have waiting lists and department consent applied so you will NOT be able to add these courses.

Course enrollment for Spring 2018

Appointments for course enrollment began on Monday 26 March and open enrollment begins on Wednesday 28 March.

For students trying to add CS courses, we encourage you to review the course selection page.

In Computer Science,  we drop the enrolment caps by approximately 15% of the total enrolment number for the course to give advisors room to handle special cases. We will return the enrolment caps to their actual size in the second week of classes after we have had time to deal with the special cases. This will occur on Friday, May 4, 2018, (we don't know the precise time) and remaining space will be available on a first-come-first-served basis only if the section isn't already at its enrolment total. WHAT IS A SPECIAL CASE?
1. Students who selected courses but something went wrong because of: enrollment capacity in a course **a time conflict **an academic enrolment block was applied after course selectiondropping or failing a course after course selection** Please re…

CS/Data Science/Digital Hardware option transfers NOW OPEN

The CS Undergraduate Advising Office has opened applications for CS transfers for Fall 2017. The online application is available at will be open from Tuesday, December 5 until Sunday, December 31, 2017, at 11.59 p.m.

We're accepting applications for:

Transfer from Math to CS - at a minimum, must have taken CS 136 or be taking it in Fall 2017.Transfer from CS to BCS (Data Science) - must have taken STAT 231 or be taking it in Fall 2017.Transfer from CS to CS/Digital HardwareAdding a Joint CS to an out-of-faculty planTransfer from outside of Math to CS (pending approval from Math)Answers to common questions about the transfer process can be found in the CS FAQs (particularly #2 and #151).
