Earth Day + Mobile Logger

Wednesday, April 21st, 2010

1260201893_posterThursday, April 22nd is Earth Day. The weather is looking to be sunny and 65 degrees in New York City. Sounds like a perfect day to ride your bike (or walk, run or whatever you like to do outside). Since you’re already going to be out there, why not log the trip, help me with my thesis, and have your data made into some visualizations I’m preparing for the project?

It’s pretty simple…download Mobile Logger from the App Store (iPhone 3G/3GS), open it, then tap Logging switch to begin. Put the phone in your pocket, bag, mounted to handlebars, or wherever is convenient and go. You can double-tap the screen to disable the display, but shouldn’t lock the phone.

When you’ve reached your destination, tap the logging switch again to stop and you’re done! The log data is automatically uploaded to the Mobile Logger server and will be included in my research (this uploading can be disabled if you’d like to use the app without contributing to the project, too).

What I’m really interested in exploring is a sense of connection between us by sharing our experiences. I ride a bike daily through NYC, and encounter many other cyclists, walkers and drivers. We pass each other in a moment, or perhaps share a lane for a bit and then continue on our separate ways. How does my 5 mile, 25 minute ride from Greenpoint to the East Village compare to someone riding from Queens? What does a ride around Prospect Park share with one in Central Park? What’s the loudest part of the city for a cyclist? Where are the most frequently ridden routes?

I’ll be working with the contributed data to create visualizations which attempt to answer these questions. The “dashboard” of the system will be present at mobilelogger.robertcarlsen.net. More info about the app is available on it’s documentation page.

Times UP! is also organizing a ride at 7pm from Union Square if you still need another excuse to get on a bike, skates or a board. It would be neat to see a bunch of riders converge on a location, then ride together in a group. I really want to see what that visualization would look like…

Thanks, and enjoy the ride!

it’s real (time) !

all eventsafter a couple of late nights, i have a proof-of-concept in the real-time cycling-related datalogging. the reasons behind the project are still getting sorted, but lately my interest in ubiquitous urban sensor networks has been piqued and this is a tentative exploration in that area. sensors don’t have to remain static as part of physical infrastructure…millions of people are carrying millions of sensors around with them daily.

ITP 1-in-1: bike blinky!

Sunday, October 4th, 2009

blinky_on_bikeFor the 1-in-1 Project as part of ITP’s 30th anniversary celebration I over-engineering the simple bicycle blinky light. Why go for a simple, off-the-shelf blinky light when we can build a much more complicated one ourselves?!

I’m creating an animated display, which changes to solid red while braking.

Update: (5:26) It’s been a long night, but it all came together. I wish I could have finished at the floor, but sometimes you need to go to your cave. The bike blinky light is all I could have asked for…it’s obnoxious, it’s animated, it has a handlebar control to switch to a flashing warning mode. (more…)

Rest of You: Bike Forces

IMG_0726(note: I’m awaiting the HR sensor, this is mostly outward forces)

I’m logging the acceleration forces at the handlebars of my bicycle while riding through New York City. The body has roughly three contact points with a bicycle, the hands at the handlebars, the “seat” at the saddle, and the feet at the pedals. The downward force of the rider’s weight and pedaling force and the upward forces of the bicycle rolling over uneven ground are distributed over these three points. I was interested to see just what kind of forces are “pushing back” that I may not be aware of, myself lost in the act of simply keeping the bicycle upright and safely navigating through traffic.

handlebar_vibrationTo contextualize the raw accelerometer data I also tracking GPS location and eventually geocoding the raw data in software. The bicycle sensors are being transmitted via Bluetooth to a mobile phone and the data is logged with a custom written (but now open-source!) python script. Below is the first draft of the visualization. (more…)

handlebar_vibrationThis is just a teaser for a project I’ve recently begun, but I had an “a-ha” moment when the visualization program finally came together just now and wanted to share…

This is geocoded accelerometer data from the handlebars of my bicycle on my commute from Greenpoint to ITP in the East Village. The sample at middle of the graph, and the red circle on the path coincide. I realized just now that this is a seam in the Williamsburg Bridge. Neat.

I’ll post proper documentation of the project as it becomes more robust…but I’m excited. Waiting for the heart rate monitor interface to arrive…looking to couple internal status with external events…

i hate losing things….in this case my house keys and special lever for my bicycle wheels. my exhaustion and a faulty carabiner keychain conspired to drop my keys on the NYC sidewalk with me unawares. i didn’t realize it until i was standing at my doorstep in greenpoint at 3am, in the cold and windy night. in the end, although i had to ride 25 minutes back to school (and then home again) at least my keys were still there….
