VISUAL PERCEPTUAL EXPERIMENTS

I am collecting data for a visual perceptual experiments in my lab for a conference submission. The goal of the study is to understand material perception of computer animated cloth under external force.You will be asked to come to my lab and do a few visual psychophysical experiments. The task include looking at videos and make simple judgements.  The experiment will be about  2 hour long and you will be paid $12 an hour.
Time: this week and weekend.
Place: SCAN 160
If you are interested, please schedule with my research assistant Wenyan Bi at wenyanbi1990@gmail.com
