CTRL-Labs themselves acquired the wristband tech from North/Thalmic, who pivoted into smart glasses for a few years before being acquired by Google.

> In an interesting twist, CTRL-Labs purchased a series of patents earlier this year around the Myo armband, a gesture and motion control device developed by North, formerly known as Thalmic Labs. The Myo armband measured electromyography, or EEG, to translate muscle activity into gesture-related software inputs, but North moved on from the product and now makes a stylish pair of AR glasses known as Focals. It now appears the technology North developed may in some way make its way into a Focals competitor by way of CTRL-Labs.

That's not true. Thalmic did develop an sEMG band, but the tech developed here was created by Ctrl-labs and continued development within Meta.

nope. the technology was invented by CTRL-labs, and at Meta after the acquisition.

yes the Myo was a similar, earlier, and less capable technology also based on EMG sensing.

    I had one of those Thalmic Myo armbands 12ish years ago. Used it a couple of times and then forgot about it. From memory, there were only a few gestures available to program, and anything I could think to sync them to was just as easily handled with keyboard shortcuts (show desktop, close window, change workspace, etc).

Should be EMG, but is it normal EMG or sEMG?
