【智能游泳“计步器”:水上AR】

有很多只能小工具可以用来计算和追踪你的跑步活动路径,但很少有游泳的追踪小工具。如果你想要一种专门为游泳而设计的佩件,而不是只能用其他产品充当游泳跟踪设备,一个新的健身公司前侦查仪器雇员发现了解决这个问题的第一个产品,199美元的Form游泳追踪护目镜。最终的测评结果是,它有着令人惊讶的可用性。表单护目镜记录了你的分割时间、划水次数、游泳长度、卡路里等等。它也与你的手机分开工作,你在锻炼后将数据同步回你的手机,在那里你可以检查你的表现。

Form Swim Goggles review: aquatic AR - The Verge
There are lots of smart gadgets that track running, but few when it comes to swimming, at least if you’d like something that’s built for swimming first, as opposed to a device with swim tracking features tacked on. It’s that problem that Form, a new fitness company founded by former Recon Instruments employees, is looking to solve with its first product, the $199 Swim Goggles.

With this device, Form has tried to marry a Google Glass-style AR heads-up display with Fitbit-style tracking, specifically and exclusively for swimming. The end result is surprisingly useful, although one that’s better likely on suited for truly serious swimmers.

The augmented reality aspect of the goggles, while seemingly over-the-top at first, actually makes a lot of sense. There are numerous fitness trackers that can track swimming, including ones from category heavyweights like the Apple Watch or Fitbit’s newer smartwatches. But according to Form’s CEO Dan Eisenhardt, they all have the same problem: wrist trackers are bad for swimming, because you need to use your arms to swim. It’s almost glaringly obvious in retrospect, like putting a fitness tracker for running around your ankle.

As for the display, it won’t be winning any awards for resolution: it’s effectively a yellow dot-matrix display that projects into your line of sight, similar to any number of other AR solutions. The whole thing is controlled through two buttons, but it’s simple enough to manage on the device, given that most of the settings are packed away in the app.

Unlike most run trackers, though, the Form goggles can only show you fitness data, such as split time, stroke count, lengths swam, calories, and more. It also works separately from your phone, which is good since you won’t have to leave a $1,000 device unattended poolside. Instead, you sync data back to your phone after your workout, where you can then examine your performance.

As a swim tracking device, though, the Form goggles are among the best in terms of what data they can pick up. When I reviewed the Fitbit Charge 3 last year, I noted that it could only display time and heart rate on the device, with the rest stuck in the app. Recent Apple Watches can do more, but the Form goggles beats both of those product lines. The goggles can show different metrics for different points — displaying stroke count during a lap, for example, lap time when you make a turn, and how long you’ve been resting and how many calories you’ve burned when you pause, for example. Those options have to be set in the app before you go, so if you haven’t added a particular metric to show up, you won’t be able to access it out on the water.

Since it’s untethered from a phone, there’s no way for the Form goggles to tell how long the pool you’re in is, though, so you’ll also have to input that in first when you start an exercise. But once you do that, the Form goggles can do the rest through a combination of an accelerometer, gyroscope, and a whole bunch of algorithms calculated by an on-board computer that can tell when you’re swimming, stopped, or — most importantly — doing a turn at the end of a lap.

Like the rest of the Form goggles, it’s a smart system designed specifically for lap swimming. Unlike, say running or biking, a swimming pool has a standardized length, which means Form doesn’t need to waste time, money, and space on GPS tracking to figure out exactly how far you’ve swam. It just needs to know how big your pool is and when you’re switching direction.

At least, in theory. The whole system relies on you being a decent swimmer, since it’s not really measuring the actual distance you swim, just multiplying out how many turns you’ve made against how long the pool is. When I was swimming with good technique (like my first few laps), the goggles worked great, tracking not only my laps but even correctly identifying when I was swimming freestyle, breast stroke, and back stroke. But as I progressed and got sloppier, stopping halfway through a lap or switching strokes part of the way through, the goggles got confused. It still identified strokes correctly and measured my pace, but it treated each of those interruptions as separate laps, giving me credit for twice as much swimming as I actually did.

This likely won’t be an issue for people who are actually good at swimming, which I suspect most people investing $200 in a swim tracker are. But currently, there’s no way to edit that lap data in the app, so you’re stuck with the bad metrics if it does legitimately mess up.

The base goggles are also well designed. I’m no expert on water goggle quality, but the Form goggles held up well in my test swims, keeping water out and preventing the glass from fogging up. Form also includes several different bridge pieces, so they’re adjustable for different size heads. The design also lets you flip the goggles over, allowing you to wear them with the display on either eye.

The whole thing looks and wears like a standard pair of swim goggles, too. I didn’t notice any extra weight from the display while swimming, and while the non-removable display module is definitely noticeable, I didn’t get any double-takes from anyone at the pool for being some sort of aqua-cyborg.

It’s that emphasis towards solving these swim-specific problems that defines the Form Goggles, for better or for worse, because that’s all they can really do. A Fitbit or an Apple Watch can track swimming, running, and biking, and a number of other fitness activities for a similar cost, while also working as an every day step and heart rate tracker. They also can provide day-to-day step and heart-rate data, and function as smartwatches with notifications, music control, and everything else a smartwatch typically provides.

It’s almost like the difference between buying an iPad or buying a high-end Kindle — do you want a device that can do everything, or one that does one niche thing very well? (The obvious caveat there is that a lot more people are serious about reading than competitive swimming or participating in triathlons.)

If you’re a serious swimmer — someone who’s swimming competitively, training for a triathlon, or just takes their everyday workout seriously — the Form goggles are a great option for you. But if you’re only a casual swimmer, you’ll likely get more benefit out of Apple, Fitbit, or Samsung’s jack of all trade devices than this master of one.
