Mobile Videobiking at Car Free Vancouver

As planned, yesterday, Roland and I strapped N-series phones to our bikes, pulled along a wi-fi/WiMAX equipped trailer, and performed Le Tour Des Car Free Fests. As my Sportstracker data indicates (in two segments), we managed to visit three of the four main sites for Vancouver’s Car Free Day.

Nokia Sportstracker routes came out in three segments, and the third segment either disappeared or NSB shut down in the middle of it.

We had severe connectivity issues throughout the ride, which meant that we only achieved a few minutes of live streaming video at a maximum. Roland has collected up most of the links for this material here, so I needn’t be redundant and repost it. The two remaining challenges for this sort of exercise (which had been identified during our last pretest on June 11, but not since resolved) are the annoying authentication page on Free-The-Net, and the limited upload speeds of WiMAX. Clearly, another solution, other than Rogers Portable Internet, is in order.

I must say, the Car Free day is a great event. I’m glad it’s expanded into other ‘hoods this year. Each one had a very different vibe. I’ll do a follow-up post on this dimension of the experience later. Today I need to actually spend some missed time with my daughter. The Father’s Day extended dub remix 12″, or something…

Car V Bike Pretest 0.2

Today we tested our live streaming video and GPS tracked bike commutes, this time using a third bike to pull the wifi mesh/wimax trailer.

I worked for about an hour this morning assembling the mounting clamps for the two phones on two bikes. Both worked very well and withstood many bumps. The angle and steadiness of the image is good (the lighting and resolution is not – see stream at right).

The most significant single problem is that our maximum upload bandwidth via WiMAX is just shy of 200 kbps, which means that our live streams only last a few seconds before they buffer. However, on the plus side, I don’t think we ever lost the WiMAX signal during the entire 10 kilometres we traveled.

There were also handset UI issues – everything in the phone must be set to “public” prior to attempting to stream or send GPS data, incoming phone calls put the N82 (and N95) camera on standby, interrupting the Qikstream, and whenever the wi-fi connection is interrupted (whether this was due to authentication issues with Free the Net, or due to me simply riding temporarily out of range of the mesh router), the stream is similarly paused while the Qik application uses Nokia’s EasyWLAN to find a new WAP.

More notes on this later; I’ve got spreadsheets to work on…

Car V. Bike pre-test :: Nokia Sportstracker and Qik

Today Roland and I mounted our Nokias (running Qik and Nokia Sportstracker Beta) on our bike helmets and rode around False Creek (see this map of our route, and see my Qikstream here). Due to rain, Scott (who was to supply our connectivity on a third bike, pulling a trailer containing a wifi mesh router connected to a WiMAX modem) bailed, but we took the trip anyway (for those who have no idea why we did this, click here and here for some back story)

The handsets (an N82 and an N95) both crap out after 25 minutes of Qik video recording (the phones store the video in RAM I believe), and with nowhere to upload the video to (no wi-fi, no data plan), the video cameras simply go into standby.

I used a velcro strap designed for the iPod Nano to secure my N82, and we used a combination of grip tape and duct tape to affix Roland’s N95. IMHO this gives an excellent POV, which is more or less shock resistant (as it’s got that wonderful spinal thing helping keep everything fluid [good thing I got some kundalini in yesterday], but makes the cameras impossible to operate. So you have to get apps running first, then lock the keypad, then mount it in the helmet without locking up the camera or obscuring the lens. A better alternative would be to use Gorilla Pods (or some homemade facsimile), which I think we’ll have to do next week.

Roland’s Nokia sportstracker data uploaded without a hitch (the map link above) over EDGE, while mine has been experiencing issues for a few days now over wi-fi. Any pointers on how to get past the “uploading to service” hang in NSB would be very helpful. Update – I managed to get around it – see comment below, and see my map here.

I see I’ve angled my camera too far down – it’s actually angled the same as Roland’s, but my handlebars are racing style, so my head actually leans down more than his. Chalk that up to first time glitches.

Also of note – the N82 survived about 20 minutes of moderate rain. It got soaked and kept on ticking.

Anyway, check back for an update when we’ve tested out the WiMAX setup. You can also tune into the Car v Bike event next Sunday, June 15, here.
