Emotiv, you are *so close* with this that it hurts me to even work with it.
Include some extra damn felt pads with the kit. The felt pads fall out every time you put the thing on or take it off, this is a ridiculous design oversight and needs to be fixed. To me, this is inexcusably lazy.
And what do the pads cost each? A couple of pennies? Include an extra 20 of them with the device. This should be obvious.
Okay, so you obviously hired a good designer to build the packaging, and to build the carrying case for the sensors, good job.
Where was this designer when you were trying to decide if the thing should be adjustable? I have a *big* head. The epoc is uncomfortable for me to wear.
Headphones, which this device are is similar to, have been adjustable since ever. How on earth did you overlook this? Is it a distance thing? Timing? Are we building supercomputers from the 80s here or something?
The readings should be analog, so I *guess* this is forgiveable. It's still annoying, though.
Annnnnd then there is the issue of your fucking archaic view of your SDK.
Tan Le, one of the cofounders, comes from a telecom background. The best I can come up with on this one is that she is bringing her [I'm sorry for being crass here, but] stupid, ignorant telecommunications-technology paradigms to this.
Emotiv has an SDK for their epoc. Good. Good job, emotiv.
What is *not* a good job here is that the SDK costs something like $750.
As far as needing some super special magic software that took a bunch of time to develop and needing to recoup your investment: fuck you. No, you don't. You're reading voltages and then sending them over USB. It isn't difficult.
In fact, it's been hacked since shortly after the device was released. The annoying bit here being that part of the hack required cracking the *encryption* that you're using when sending the data.
Really, emotiv? Really really?
This thing should be a keyboard, or a light switch.
You've sold...what...around 8000 of these? (order numbers are sequential, mine was in the 8000s.)
At $300 each, that's about $2,500,000. Not awful, but for a company that has SO MUCH potential, that's embarrassing.
Assume $1000 each (if you bought the SDK), and that's still only $8,000,000...after three years. And there is *no way* that that many people have dropped $1000 on your device. If you're doing that, you're working in a lab with a "real" EEG.
But you still got me, didn't you? I still bought the thing, I'm still going to hack with the thing, I'm still going to buy more pads for the one that I already lost in the carpet.
The difference here, emotiv, is that I'm going to hate you the whole time, and the whole time it's going to be in the back of my mind that if any of my work gains traction and requires more devices, I'll be using yours as a last resort.
Last night I spent some time reading about DIY EEGs (all an EEG is really doing is reading voltage differentials). The fact that I was doing this less than 12 hours after receiving your product means that you should be heavily re-evaluating your relationship with your customers.
