The Myo Arm Band is a new, interesting way to control your devices with the use of gestures... Is it the next big thing in device control?

 

[burningfyra]

thanks nick was wondering what was on lucks arm last vid

[Flight1sim]

Oh is that what that was

[RevoltTrain]

Seems amazing. If they fixed what Luke mentioned I'd buy it almost immediately 

[niofalpha]

This looks good

[Lolzious]

Futurama is becoming more of a reality every day!

:DDD

Thanks again @nicklmg you are the best.

 

After the crap on the forum tonight this is EXTREMELY refreshing

[Deletive]

So thats what he was wearing in the past videos.

[Speedyv]

I thought it was some tribal Hawaiian armband.

Is Luke's voice screwed up? He sounds horse...

He is sick. Like the intro says

Not sure if thing about pterodactyl was teaser to upcoming video, or just random thing that Luke decided to say.....

 

 

 

We need more videos of other people doing LTT videos. Luke does the occasional LTT vid, and Taran does the occasional TechQuickie. Even Brandon had a video. 

 

I want to see Edzel, Nick 1 and Nick 2 do some videos

[ROK]

what an edgy video

[wolfgang]

interesting. not for me though.

[m_tieu]

Cool concept, but needs more refinement before its something that I would buy.

serious question, i don't have a thumb, does this work?

[EdZ]

The unfortunate truth is: it's never going to work well due to fundamental technical limitations of available sensing technology.

 

The IMU-based portion (sensing what the orientation of the band is, and by extension, the orientation of your arm) will work as well as any other IMU. Great for roll and pitch, Yaw drift dependant on local magnetic conditions (or just bad yaw drift, if the magnetometer is ignored entirely).

 

But the myoelectric portion is never going to work well. For medical applcations, there are two ways to apply electrodes for effective myoelectric sensing that work in practice:

1 - A trained technician applies the electrodes to specific muscle groups, with the aid of the user performing tasks to flex those groups in order to lcoate the sensor properly

2 - For prosthetic applications, the same process is used to locate the electrodes initially, followed by the electrodes being embedded inside a stump-cup to keep them in a fixed position over the stump

 

Just wrapping the arm in a handful of electrodes that cover a tiny portion of the arm, are not positioned over selected muscle groups, and may shift not only between uses but while in use, is not going to get good results. With a good training process and good filtering it may be able to reliable discriminate celnched-fist (many muscle groups activated) from relaxed-open-palm (few muscle groups activated), and maybe some degree of the current direction of wrist flexion and extension force*, but that's about it.

 

*Not wrist orientation, but the force currently being applied to the wrist joint. Because the Myo can only sense muscle activation, it cannot tell your wrist bent all the way out and trying to superextend from your wrist bent all th way in and just beginning to swing back.

"Any device"

[pk-man]

needlessly pointless product is needlessly pointless.  Motion control is not a one size fits all kind of thing.  It is good for certain situations but there are times when it's just not intuitive and it'll only make yourself look like an jackass.  Why are they trying to reinvent the wheel? This is like that other concept where you kick your leg to left click.  Just pure lulz.

 

and also Linus getting more sadistic everyday lol

This would be very useful if you were in a bad situation (say.. getting mugged, worst case scenario), you could make a slight gesture that calls 911 (if I'm understanding this right.)

serious question, i don't have a thumb, does this work?

If you could flex the muscle in your forearm that would control that thumb it would probably be fine - not sure though

All of that makes sense to me... I'm not educated on the electronics specifics of the sensors but I had hope coming from the NIA - the NIA was actually quite good at detecting things like glancing, smiling, etc... but obviously it is a very different application

 

"Any device"

If I said that I meant any supported device - my bad - there is a list on their website

That would be bad - a slight gesture would mean it was improperly calling 911 all the time

It's in the video title

[Bsmith]

seems interesting but not interesting enough for mme yet, altough its functions are more interesting then certain things-yes i mean the razer nabu(X) in its current form-

[Nup]

AHa! that's what it is! Look forward to watching it when i get home 

[Mecael]

That's not a pterodactyl that's a pteranodon!
