This post is the fifth in a series of nine illustrating my trip to Japan. On my fifth day in Japan, March 25th, Matt and I decided to take the time to do some sightseeing and go to the various areas around Tokyo, including Central Tokyo (æ±äº¬), Ginza (銀座), Asakusa (æµ…è‰), and Shinjuku (新宿区).

This post is the fourth in a series of nine illustrating my trip to Japan. On the fourth day in Japan, March 24th, we recouperated from a fun evening the night before and got ready for another round of presentations. We caught up with Bert at breakfast and figured out the plan for the day.

This post is the third in a series of nine illustrating my trip to Japan. On the third day, March 23rd, I presented the paper I co-authored, “Frequency analysis of the detectability of virtual haptic gratings.” It was surprisingly stressful (this was my first “real” presentation to a group of >200 individuals), but it went over well. Matt also presented poster on a paper he co-wrote, “Discriminability of Real and Virtual Surfaces with Triangular Gratings,” which is shown in the images below.
This post is the second in a series of nine illustrating my trip to Japan. On the second day, March 22nd, I took the time to get my bearings and get ready for the first day of the conference.

This post is the first in a series of nine illustrating my trip to Japan.
After arriving in Japan on March 21st, we caught a bus from Narita International Airport to Tsukuba:
It’s been a while since I’ve posted and that has been primarily due to the fact that I had been preparing for an oral presentation at the World Haptics 2007 conference. I presented a paper this past week on research that I had conducted with Dr. Hong Z. Tan at the Haptic Interface Research Laboratory investigating whether a linear system model can be used to describe human texture perception. Our research supports the hypothesis that the human somatosensory system may perform a spectral analysis on the proximal stimuli and that a linear system model may describe human texture perception.
I had the opportunity to present our research and to take some time to travel to Tokyo (with my friend Matt Kocsis) and Kyoto. I’m going to get back into the swing of things and start posting more projects (I’ve got a couple up my sleeve that some people might find interesting). I’m also going to post some galleries of pictures from my travels.
I’ve updated my PIC16F88 Delorme Tripmate GPS Logger, so it now includes time and speed logging. Using the trip information recorded by the GPS logger, you now have even more variables to play with. For example, using time and velocity information, one can plot not only the speed, but also the acceleration of the car (dv/dt) for a trip:

This project focused on creating a simple serial data logger for the Delorme Tripmate (also known as the GPSTripmate). The Tripmate is an older GPS receiver that can be purchased on eBay for <$20. I happen to have one that my family used a couple of years ago and it is still in great shape. It has been sitting in the back of my car for the past four years, so I finally decided to put it to good use. The plan was to create a GPS data logger that would record the position of the unit and allow me to read back the latitude and longitude after acquiring the data. My ultimate goal will be to use a small backpack to record my runs (once the weather warms up). This was a fun experiment because not only did I need to interface the PIC16F88 to the Tripmate, but I also needed to parse the output and implement an efficient storage solution. Read on to find out more information about the project, see the schematic and soure code I wrote, and find out how the data was visualized. Read More
