The Motorola MOTOACTV is the world’s first GPS fitness tracker and music MP3 player – in one device.


Motorola MOTOACTV: GPS and MP3 music player in one fitness tracking device

With multiple form factors – the device itself (slip it into a pocket), clip (attach it to a belt), watchband (wear it like a wristband), armband (great for running), or attach it to a bicycle – the Motorola MOTOACTV is a very versatile fitness tracking device.

Motorola MOTOACTV Armband: tracks distance, steps, calories burned in a GPS MP3 music player

Using GPS built-in, the Motorola MOTOACTV can accurately track distance, calories burned, pace and elevation – it can even show your route on a map, right on the device’s color LCD display.
The Motorola MOTOACTV features a built-in MP3 player that syncs with iTunes. Bluetooth enables stereo wireless headset wear for a true wireless experience.

  1. Definitely take them on the run! I did a pretty in-depth reveiw of the BodyMedia on my blog last year and I still wear it from time to time. It is definitely cool to see the data from exercise, and the minute-by-minute calories burned chart is quite entertaining. Another thing to compare the BodyMedia with is your sleep monitoring device, as it also monitors sleep (and tells me I am up way more than I think I am!) Have fun!

  2. It’ll be interesting to read how the prtucdos you are testing do their estimates and how accurate they are. Step counts are intuitively a proxy for distance, energy consumption and speed but step counts need additional information for reasonable accuracy e.g. person is jogging and jogging stride length is x. Foot falls produce greater body accelerations than almost anything else. Ultra low battery consumption devices exploit this by using the accelerometer to wake up the processor on high accelerations rather than sampling continuously and analysing the signal. Phones could do this also. For example, the Xperia Active uses the accelerometer which consumes negligible power and provides motion-triggered interrupt-signal generation . The Active doesn’t use this functionality but if it did the included Walkmate pedometer app could remove the battery use warning. However, if you only process high accelerations you can count steps but you limit the sophistication of the processing algorithm and therefore potential accuracy. We sample at 20Hz for 6 seconds out of every 30 in a and calculate features from analysing the signal to provide activity classification and energy estimates without whacking the battery too much.

  3. Step counts are porloy correlated to energy consumption. If you are running you use much more energy per step than walking. If you go faster most of the increase in speed comes from increase in stride length for both walking and running so the pedometer doesn’t notice. Pedometers also do not measure grade. Step counters can be had for a few dollars but the information they provide is not very useful. If you are mostly sedentary they are useful in quantifying an increase in walking effort and they can be useful after calibration for runners as runners mostly go at about the same speed with about the same stride length but you need more than just step count. If you want to measure energy burned you can do better measuring body accelerations which correlates well for most activities. Effort associated with grades is missed using body accelerations and effort doing things where your body is stationary but your arms or legs are working like bicycling is missed. There is an Android app that uses accelerometers to identify activities and estimate energy consumption at
