Cadence Shuffle
For pedometers and cycling computers with built-in MP3 players or smartphones with accelerometers. | |
This idea is similar in purpose to another idea in this category,
which I
found during my pre-post search for prior art, but very different in
technology and implementation. I think it stands apart and is an
improvement over the other idea, but that's not
my call as the poster to make, is it?
Any
MFD experts in the room?
Anyway, here it is:
Pedometers work by sensing movement. Shake them, and they
count
it. Some advanced pedometers even come with Mp3 players built in,
and handlebar-mounted cycling computers can even measure and
record cadence.
My idea is for a pedometer or cycling computer that measures
cadence
to select an appropriate song to match your speed at any given time.
Given that people generally walk and run with heavier or lighter
steps
depending on mood, a sensitive-enough pedometer with the right
software should therefor be able to detect moods with a certain
degree of accuracy, and use that information combined with the
user's cadence to select songs of not only the right tempo, but mood
as well.
This could also probably be implemented in the form of a
smartphone
application using the device's built-in accelerometer, for those who
prefer to use their phone for everything. See the Velocomputer app
(linked to in the Wiki link I posted) for if you have doubts about a
smartphone's accelerometer capabilities. I just downloaded it to my
phone to test it, and it friggin' works! Even counts cadence and tells
you with a weird voice if your cadence changes, saying 'cadence low'
or 'cadence normal' or 'cadence high'.
The similar idea.

That's actually more thought than I'd put into it, Ian. |
|
| |
I could foresee problems with positive feedback. |
|
| |
[ian], I don't think [21] was using "cadence" in that technical/music-theory sense. |
|
| |
[Ian], the beat, time, or measure of rhythmical motion or activity. (Merriam-Webster's Collegiate Dictionary, 10th ed.) |
|
| |
Ian, I was referring to the military's definition of the word, which
also is the exercise community's. Cadence is the speed at which
you step or pedal. For instance, standard military marching
cadence is 2 steps per second. Doubletime is 4 steps per second. |
|
| |
//(Merriam-Webster's Collegiate Dictionary//
That "dictionary" can't even spell "colour", "centre" or "labour" correctly - I wouldn't trust it as any kind of authority on the English language. |
|
| |
Ah, the beautality of words. |
|
| |
I think what [IT] is describing is the vowelly-challenged "rhythm". |
|
| |
Sounds like a good idea, but how would the player/pedometer know the tempo of a song before it actually starts to play the song? |
|
| |
The songs would be selected from a several playlists, each
playlist sorted by tempo, mood, and combinations thereof. It
may require a dedicated application to choose the appropriate
songs from each playlist, and would be easier to do if it just
chose from the downloaded music files in your phone, but could
also be done by streaming samples from a service like Pandora
and matching them to your mood and cadence. Lots of music
sites have the option of sorting songs by speed or genre. This is
just an extension of that same kind of program. |
|
| |
Mood of mover is still going to be tricky. Another
data set is going to be needed on top of the cyclic
cadence. What would differentiate an angry song
with a happy song of same BPM? Bluetooth pressure
sensing insoles anyone. |
|
| |
From what I read in the pedometer link, some pedometers and
fitness
trainers actually do integrate with shoe sensors for greater
accuracy. Not sure if they use Bluetooth, but some cycling
computers, particularly the Velocomputer, definitely do. |
|
| |
It is satisfying... But it does the beg the question
you mention, with so many music streaming apps
available and the widespread adoption by the
unwashed masses of accelerometer-equipped
smartphones, why HAS this taken so long? |
