“For humans, touch can connect you to an object in very personal way, make it seem more real” – JLP

hap·tic (hap’tik) : adj. Of or relating to the sense of touch; tactile.

Since 2005, I have been involved in research with the Purdue University Haptics Lab (HIRL) led by Professor Hong Z. Tan. My specific research involved studying human texture perception, using both real and virtual textures. I am a co-author on a paper presented at Haptics Symposium 2006. I am the primary author on another paper that was presented at the World Haptics 2007 conference in Tsukuba, Japan. I have also completed a journal paper that was published in 2013. I am interested in further research involving how humans perceive texture, how well they do, and new applications of virtual haptic and immersive environments.
