Slow motion video to evaluation form

Most coaches evaluate an athlete’s form to determine is there is wasted motion and ways to improve performance, speed, and efficiency. It’s no different when the athlete is an animal. This is definitely true for canine agility.

While I do not compete with my dog, Nick, I’m no less fascinated by his motion and performance.

It’s difficult to evaluate gate, stride, jump style, height, etc. when you are the athlete or running along with the athlete. Video can help. Slow motion video can help even more.

Today, high definition slow motion video is as close as some smartphones. The iPhone 5s in a good example. The Panasonic Lumix SZ40 is another good example. Both can shoot 120 frames per second. That gives perfectly smooth video as 1/4 speed and usable video at 1/8 speed. The Lumix can even shoot SD quality video as 240 frames per second.

I use a simple tripod and a modified car mount for the iPhone.

Evaluating the Jump

The results show that Nick jumps higher than he needs to. It also shows, his hind end is higher well past the jump. He is wasting energy.

Of course, given how much energy Nick has, I’m happy to have him waste a bit of it as often as he likes !

an Android vs iPhone debate – which really isn’t about Android or iPhone

The following is an exchange that, at first, appears to be an Apple-fanboy being egged on by a Google-fanboy. It starts out as most of these type of conversations do. However, once it gets going, it’s transitions to the perceived economic "gouging" of telecom echo systems. Even then, it doesn’t seem completely balanced. The reality is "things cost money" and markets vary around the globe for a large number of reasons and its nearly impossible to boil it down to a single factor.


Android-er: I got a beautiful Android phone that I use as a mini-tablet. 5" full-HD1080p resolution with Gorilla Glass, quad 1.5 GHz processors. So far I have not used it with SIMs aside from testing it. Unlocked; vendor-neutral hardware and software interfaces throughout.

$260 is as good or better than most phones on the market costing 2-3x, and it is totally unlocked. I’m not an Apple fan, so I cannot give an unbiased comparison, but I’d take this over an iPhone any day.

One downside for some: 3G only, not 4G+. But I am unwilling to pay outrageous monthly data plan costs, and I mostly need a data plan when I travel internationally, and local data plans are generally cheap compared to USA’s, especially roaming.

iPhone-er: I’ve come to realize that "Android vs iPhone" is a lot like "Chevy vs Ford" for truck owners.

Android-er: Except that neither Chevy nor Ford lock you into vendor-specific and high-priced parts and accessories.

iPhone-er: My iPhone integrates seamlessly with my truck. I’m sure your phone would too. No additional accessories needed. My open source media player supports AirPlay. My Sonos integrates freely with my iPhone. So, I’m not seeing the high priced vendor-specific accessories.

Android-er: Did that seamless integration involve a proprietary hardware connector? If so, you paid Apple for that, too. Do you have your choice of wireless plans? Apple gets a cut of that. Do you get to install apps from anywhere you want, or are they only the ones that Apple approves via their store? Can you load music and videos onto the device using anything besides iTunes?

iPhone-er: No costly connections required for my truck. The apps I use on my iPhone have a similar cost of Google play. I can get an iPhone from all the major carriers around the works. As a consumer, I don’t see (or pay) a difference.

iPhone-er: My point is that we both win. Consumers get a choice.

Android-er: And my point is that with Apple, you pay extra at every bend and turn, and do not get freedom of choice. Sounds like you’re happy with your decision despite price, so good on you!

iPhone-er: I don’t see the price difference you are implying. Vendor data plans are for the data and not specific to the device. So I’d pay the same for my plan on an iOS Device or android. The app prices are the same too.

Android-er: What did you pay for your iPhone? Did buying one involve being locked into a data plan that has a high fee for early termination to pay off the phone? What do you figure is the effective price for your phone given that?

iPhone-er: If I need a data plan, then I’m going to pay for a data plan. My point is the cost of the plan is the same, regardless of which phone. In the end, we both pay the same for the device and we would pay the same for the plan.

Android-er: So what did you pay for your phone? Is it locked to a plan?

Android-er: If you don’t want a data plan, what does the phone cost?

iPhone-er: I want (and use) a voice and data plan. And my devices hold there value so well that I sell each, two (or three) years later, for what I paid. It’s like being loaned the device for free. They are all unlocked – either on day-one or when I’m done with them.

Android-er: But you pay for it every month.

iPhone-er: It’s no different than my home internet, home phone, etc. I use all of these, to the maximum value. I buy the services I need.

Android-er: But one reason your services are so expensive is you are paying installments on your phone. And you don’t get that money back when you sell it.

iPhone-er: I think you are missing the point I was trying relay. If I want a particular voice and data plan, there is not one price for an iPhone and a different price for some other phone.

Android-er: I think there are data+voice plans that are less expensive if you bring your own device. Therefore, one that includes an iPhone means you are making a monthly payment by way of the difference in price. And getting an iPhone means using only a few carriers that support it, by agreement with Apple. Am I wrong?

iPhone-er: Lots of carriers support iPhone. I count 36 just for US+Canada.
If you want to BYOD you can bring whatever you want (as long as the carrier allows) – iPhones included.

As for a BYOD price vs not, it comes down to the cost of the service you buy. As a reference, I just looked at T-mobile’s BYOD price of $60 for talk, text, and 2.5GB vs ATT $50 for talk, text, and 2GB. And ATT is "subsidizing" the phone.

Android-er: Thanks for the data point. Personally, I think these are outrageously expensive plans, especially since they don’t even roam internationally – which is furiously more expensive. And I suppose you also have a home data plan, which costs more yet, even though one typically only uses one at a time. In total, that’s a lot of money for being connected.

I’d love to have a mobile connection, but not at these prices. I’m amazed that American consumers are willing to pay them. It’s nowhere near that expensive overseas, and overseas, you can get pay as you go.

iPhone-er: There are pay-as-you-go in the USA but they tend to only favor very small usage.
A quick check shows 2GB in Germany on O2 is $50. Singapore seems to be better at about $32. Hong Kong is $48. But these are data only so the total goes up when you add in voice.

Android-er: I can get 2GB for one month in Thailand for $18. That’s more than I need, and there are smaller plans too.

Android-er: Could you give me a pointer to pay-as-you-go data plans in US? I have searched and not found them.

iPhone-er: If I compare an engineer’s pay in Thailand vs USA then that $18 is a significantly higher percentage of income than the $50-$60 in the USA.

A quick Google search of "pay as you go" finds many USA options.

Android-er: The point is not engineer’s pay in two countries – it is that if they can be profitable at $18 in Thailand, then surely Americans are being gouged when they pay $50-60/month.

iPhone-er: My guess is they can be profitable at a given price point because their costs are lower and costs are likely lower in large part because incomes are lower.

I suspect most things cost a lot less in Thailand than in the USA.

iPhone-er: This has been interesting and has promoted me to do a bit of global economics research. Thanks for the discussion.

Stereoscopic photos with an iPhone

Different situations promote different types of photography. Great lighting of subject with lots of depth makes me want to try my hand at Stereoscopic photos.

For near sighted people with a smartphone, it’s pretty easy to view some types of stereoscopic images – the ones with the left image on the left and the right image on the right of the stereo pair. You just remove your glasses, hold the screen close and relax your vision. The small screen of a smart phone makes this method easy. Far sighted people tend to find it easier to have the image order swapped, hold the image pair at arms length and cross their eyes. Larger images work better in this case.

My workflow is pretty simple. For panoramic vistas, I find a point in the distance and frame my picture on it. I then lean 8-12″ to the left and center the frame on that point and take the first image; lean 8-12″ to the right and repeat. Since the iPhone has the option to show a grid, it helps keep the images squared up.

I use the Diptic App to place the two images. It’s 16:9 frame gives two squares and displays well on a wide screen smartphone when held in landscape mode. You may need to move the images around a little if your two original pictures we not aligned well when you took them.

iPhone HDR is pretty impressive

It’s interesting to see how photography has changed over the past two decades. While most will talk about the change from film to digital, the real change has come from the silicon chips and algorithms post processing all of that digital data.

More and more processing power is available in tiny packages and buried inside cameras and cellphones.

Of course, the creativity is still in the photographer – deciding on subject matter, composition, and how much image processing is “just right”.

The photograph attached to this post is direct from the iPhone Camera App using its built in HDR feature. The only additional manipulation is done by this blog which recompresses all JPEG files using a 75% ratio to save on storage and download bandwidth. it’s not perfect and I know a better image could have been created using multiple images from a DLSR camera and Photophop.

Integrated Car Audio

Bluetooth and USB integration
Bluetooth and USB integration

Having recently modernized my transportation to a 2011 Ford F150, I’m having to acclimate to modern technology in car audio.

Perhaps ‘acclimate’ is too strong a word. “Shocked that it works” is really what I’ve been thinking.

The truck in question has an early version of Microsoft’s Sync – which provides some level of voice control and integration with smartphones. In my case, the capabilities include a direct USB connection and Bluetooth. The Bluetooth integrates my phone for voice dialing and hands free calls. It also plays music (both playlists and from Pandora). The USB connection doesn’t give me phone integration but does give me the music integration and adds song text on the display. Of the two, Bluetooth is easier and more function – as soon as I enter the vehicle and start up, the Bluetooth connect is made automatically. I don’t even need to take the phone from my pocket.

There is one oddity. You can charge the phone from the USB connection but when the phone is connected to USB it takes precedence over the Bluetooth connection. If you want the benefits of Bluetooth and you want to charge the device, you need to use a cigarette adapter.

BTW – the photo is from a recent road trip with Pandora playing on the iPhone thru the USB connection while simultaneously running TomTom navigation.

Ain’t technology grand ?
