RowMotion for Handicap Rowing

Handicapped Athletes can benefit a lot from using RowMotion in their training. Johannes Schmidt, who sent us the picture above, is already using RowMotion successfully in training. The University of Hamburg has recently published a study on using sonification based feedback systems for handicap rowing. We will present a short list of features we have already implemented or plan to implement in RowMotion. If you have any questions or another great idea how we could help disabled athletes with RowMotion,  just drop us a line and let us know. We are always happy to work on innovations in this area.

Arms and Shoulder Rowing

Athletes participating in Arms and Shoulder rowing have a fixed seat and may only use arms and shoulders while the trunk is strapped. The boat acceleration in this discipline is quite similar in structure to that encountered with the standard rowing technique that also employs the legs, but we observe much less absolute force. With the leg muscles being very strong, this is not a surprising result. Because no sliding seat is in use, traditional strokerate measurement using a sliding seat magnet does not work here. RowMotion analyzes boat acceleration to derive strokerate, so we can adapt our stroke-detection algorithm for Arms and Shoulder Rowers. You can enable the Arms and Shoulder mode for stroke detection from the settings.

Rowing with visual impairment

Rowers with visual impairment usually have to rely on a the cox or their coach to give them feedback about strokerate and speed information. Other measurements such as boat acceleration that are typically presented visually in a graph are inaccessible to these athletes. RowMotion features an innovative sonification feedback mechanism that allows transforming a measurement parameter into a sound. The generated sound is basically a steady tone that is then modulated by the current measurement value. Since the human aural sense has very high temporal resolution and recognition is dramatically faster than for our visual sense, sonification is a very powerful feedback mechanism.

On top of that, we RowMotion could read out certain parameters using a voice engine. If you want to get a feel for how that works in practice, you can check out our  Speaking Strokewatch App. Speaking Strokewatch is just that – a simple manual strokewatch that will read out the strokerate you have measured. With RowMotion of course, you would not have to measure the strokerate manually but would get it measured automatically from the built in accelerometer. It should be possible to seriously enhance the range of feedback mechanisms available to visually impaired athletes using sonification when other important feedback mechanisms such as video analysis are impossible.

RowMotion Complete Systems

You can easily use RowMotion with the iOS devices you already own and get all accessories you may need at online stores to build yourself a cost-effective performance measurement tool based on our software. If you’d rather not shop around for accessories or simply want an all-inclusive package with devices, accessories and the software, we do now offer RowMotion as a complete system in a nice and solid hardcase.

With a complete system, you get all the hardware required for using live coaching, sonification and video analysis, and also some waterproof cases and mounting material. We put all that into a professional hardcase, so the valuable hardware can be transported safely.

Specifically, a complete system includes:

  • an iPad 3 Wifi+4G, preconfigured with RowMotion and RowMotion Coach
  • an iPhone 3G or better, preconfigured with RowMotion
  • a WiFi Router + 12V car adapter, and another adapter  so you can use it at any 12V battery
  • iPad HDMI Video Adapter + Cabling
  • two waterproof iPhone cases
  • a waterproof iPad case

We have already deployed three protoypes of a complete RowMotion System and have received very positive feedback. If you are interested in purchasing a complete system, please do not hesitate to contact us.

RowMotion Export Tool

The export tool has been superseeded by Rowing in Motion Analytics – our new cloud based data analysis software.

 

“Your data is yours to keep.” Thats part of our philosophy, so we give you access to all the raw data we record during an exercise. Whether you want to do your own research or data archival, our export tool allows you to extract data from the binary “.rm” files RowMotion records during exercise. You can find it at exporter.rowinginmotion.com.

We do currently support exporting each individual data parameter as CSV. Each measurement point is timestamped with millisecond precision. The first data point in the logfile is recorded at timestamp 0.

We can export the following data for you:

  • Accelerations: timestamp[s] boat[m/s²] starboard[m/s²] up[m/s²]
  • Speeds: timestamp[s] speed[m/s]
  • Strokes: timestamp[s] strokerate[S/min]
  • Distances: timestamp[s] distance[m]
  • Positions: timestamp[s] longitude[deg] latitude[deg] accuracy[m]
