- written by a very novice NIA user -
== sorry for being over-complete ==
I've been trying to scan these forums for something similar, but I haven't found it using the "search" function on a couple of related keywords, nor did I find it reading a few pages of a few large threads, so I'll open this thread in the hope that it gets completed by everyone else here for my and other future visitors' use.
What I was basically looking for was a thread to know when to consider my NIA operational and when to consider it broken: a few pointers on what you should notice a healthy NIA doing. Hope this forum can become an easy support guide and I hope to figure out what's bugging my NIA and have it working again soon!
First, I'll describe my problem. I received the NIA last friday. Knew beforehand I was to expect a device that required reading the manual first, that might require several months of 'training' and that was prone to electrical interference from adapters.
Problem 1: the manual doesn't help you jack squat. same for the tutorial. It doesn't tell you how to detect whether the device is working properly and how to perform some simple very exaggerated test actions to get you started. Luckily here, (a) I know my way around electrical devices, (b) I had a trained physician nearby to explain alpha and beta signals and EEG, EOG, EMG theory, (c) I had basic knowledge of meditation, (d) my NIA seemed to work.
Question 1: Is there currently a quick-start guide in the works? I'd be happy to contribute my (so-far limited) knowledge and time in writing.
So, after deciding the manual/tutorial were disappointing, I decided to try out the device.
Problem 2: When taking the headband out of the box, I noticed that the diamond-shaped outer rim of one of the sensors was bent crooked as if it had been slightly folded around the headband and then fixed under an angle. (Since this was just the right-most sensor and not all three, I thought .. damn .. might be broken). No where did I find information on how flexible and tolerant these things are supposed to be.
Question 2: Can someone expand on how precisely a decent NIA should come 'out of the box', preferrably with detailed pictures? More importantly, can someone in the Tech Department detail the sensitivity of the device to things like bending and loose wires, connections etc.
The headband feels fairly flexible so I could imagine it not being important and decided to go ahead with trying it anyway.
I was out of town and had to use someone else's laptop with a decent processor and RAM. (Regretfully they are unavailable to me now)
It connected and flatlined at the very top of the screen.
Problem 3: Electrical interference
If the NIA is plugged in and the signal is all the way at the top, is the device broken or getting an overload? Similar problem for when it would be at the bottom? One can work with a signal that is displaying a wave-pattern within limits, but a flat line at the edge of the screen is just plain nasty. You'd be fumbling in the dark trying to troubleshoot.
Question 2: Others have mentioned it around here, but it sure would be useful to get a FAQ/Operational checklist around here. (I'll try my hand at a starter at the end of this post - please add)
So, well, I'd read about electrical interference, so I unplugged all chargers and adapters, running the laptop on battery power. I got a fairly responsive signal that I was able to get close to the red/green line, but it still seemed jumpy when I didn't experience doing anything. Picked up the laptop and moved around the room. Found a spot on the couch that was decent and hooray I got a decent signal. On with the testing of the device. Again, the tutorial nor manual were very helpful on where to start. Not even the common sense advice of "relax, look at the screen and start trying things" is included as a quick starter tip (!)
After playing around a little, I managed to calm my mind enough to get all the brainfingers to zero, except for the glance which stuck at 100%. Oddly enough, the corresponding left/right joystick did seem to jitter and also responded to my efforts of trying to keep it centered.
(In retrospect this might have been caused by me not REPLACING the nia.exe when updating, but rather running it and closing it - leading me to be using the old nia.exe the second time I connected - which reportedly had a faulty glance-bar, right?)
Problem 4: One doesn't have a clue where to start when using the device for the first time, other than the vague descriptions of 'glance', 'alpha', 'beta' and 'muscle'.
Question 4: If it is the express intention of not saying anything to not ruin the 'clean slate', why not say so? If it isn't, how about a few tips on getting quick initial response from the NIA to encourage more practice?
Using a laptop which had to be recharged every 2 hours, I was able to play a little with the device over the weekend. Myself and two other people used it and we were all able to get basic control of the muscle input. A basic game of easy Pong was achievable within 15 minutes. Within 1-2 hours of practice, I managed to score a point against the computer. After a day, I managed to score 7 points in a 30-ball game. Midway through day 2, after approximately 5 hours of use, I'd learned the gimmick of clenching my jaws (because a physician just happened to mention that it might be a good muscle to start experimenting with) and 'breathing the bat', so I was able to play a game of hard Pong; movement looked fluid, though a bit jittery, which might have come from my own imperfect control or from electrical interference. (I really hate not being able to know for sure that it's just me). I scored a few points in hard Pong, hooray.
Now came the time to return home. I repacked the device and was eagerly anticipating using it on my home system (E8400, 4GB RAM, 4x750GB RAID5/0, Vista 64 Ultimate SP1) which should clearly outperform the laptop I'd been using.
- Plug in device
- Install CD package
- Install update. (At this point I finally noticed I was to REPLACE the nia.exe instead of run it)
- Run nia software -> no device
- Try different USB port -> nothing
- Reboot computer -> nothing
- Reinstall driver package 2.000 + 2.010 update from website ... finally it works.
- Plug in device -> 100% flatline
Now, there's even less adapters in my own PC room than where I'd been using the laptop, so I had been expecting no trouble at all. As I'd been doing the entire weekend, continuously touching the NIA box during use, I touched the box -> the signal dropped, but CAME BACK UP again within a second. WEIRD!
Decided to read about grounding issues a little, found a post about static build-up.
First touched the radiator. No effect on signal.
Then touched the box. Short drop, then signal raised again. Released box.
Touched box again after 3 secs. No effect
Touched box again after 1 minute. Again .. short drop in signal, then back to 100%
Decided to try out this static theory: touched the NIA box AND touched the radiator. MAN, did that surprise me! I got a very unpleasant sensation; obviously I had a current running through me from the box to the "grounding" and apparently enough to notice it. Unplugging the USB cable seemed to stop the current.
At this point I was very discouraged. If the outside shell of the device was being continuously charged with a low-voltage/low-amp current (haven't taken a measuring device to it, yet), I was seriously suspecting it being broken. However, unplugging and replugging the usb cable still made the device disappear/reappear and the blue lights on the bottom of the device still functioned. It seemed to continue doing what it had been doing.
So no luck on grounding myself on the radiator or the NIA, no luck grounding the NIA on the radiator (with and without me as a conduit) .... the signal still was unresponsive at a 100% level. Using the latest driver, I could click on the Muscle: xxxx value and lower the sensitivity of the EMG ... that FINALLY showed me a signal line within bounds .. however .. it did not seem to respond at all to any of my exaggerated muscle movements. I was fairly certain these had worked on the same device several hours before.
Then I read something about testing the different electrodes, though not reading anything about any test procedures. So I decided to test further. Removing the headband and placing it on my desk, should drop the signal line to zero in a "clean room". It did! (I'd rebooted the software a few times, so everything was set to default). There were some very minor spikes at irregular points, but these might also have been from the device picking up me, right OCZ ???
Sure enough, placing the headband on my head again, increased signal levels to 100% again. Had I suddenly over the course of a few hours increased my brain-levels such that I was no longer able to blank my mind???
I removed the headband and decided to test the "center electrode is reference" theory. So I touched a thumb to the center electrode. The signal remained at a flat 0%. Now, holding my thumb to the center, I touched the left sensor: nothing. Holding my thumb to center, I touched the right sensor: immediate spike to 100%.
I placed the headband on my head, but pulled a little on the band to keep the right sensor clear of my forehead: yup, signal line stayed dead at 0%.
More testing: touching left and center individually with a finger: 0% flatline. touching just the right sensor with one finger: 100% flatline. At this point I was fairly certain something was broken and I was inwardly cursing that I did not have access to the laptop on which I'd been using the device (reasonably) successfully.
Question 5: Can someone from the Tech Department give a few basic testing procedures on how to ensure proper NIA device functioning?
I was again fumbling in the dark here, trying to get some response to narrow down my issues with a device that is literally a black box to me due to lack of a whitepaper. (or should I read those articles on the related brainfingers-device??)
As a last resort for finishing up this post, I pulled out an old laptop (PIII 1GHz, 256MB), thinking I couldn't do worse, while starting to write this topic. Using the laptop on a power adapter (because the battery is dead) and just 3 feet away from my main system, on the same desk, I installed the NIA device drivers from the originally included CD. No updates this time. Then came the fresh reminder (I'd had this on the other laptop too, both using XP SP2): there's NO DotNet framework v2 packaged with the NIA CD .. and since it is both necessary and easy to include, this seems like a careless omission (Come on OCZ, there's 600MB free space on that installation CD and even in case of a licensing issue .. there's plenty of space to write about THIS in the manual!). Ok, so I downloaded the .Net framework installer onto a usb flashdrive and installed it on the laptop.
The NIA software is running, though the processor is running a full 100%. Symptoms are exactly the same as on the main system: continuous current when grounding NIA to radiator through human, signal level 100% whatever I try, with the exception of removing the headband, no response when touching left or middle sensor, 100% spike when touching right sensor. I'm thinking my device is broken. Any comments, ideas, criticisms welcome.
I'd be very disappointed to know that these devices are so fragile that they cannot withstand a repackaging yet there is no mention of this made on the box. I'd also be disappointed to know if indeed there is a high percentage of NIA's returning DOA or RMA; I'd been considering the device for human and medical research among other things and still am, but would sincerely appreciate more detailed information.
Finally, I will contribute a few of my experiences in the hopes of adding to a comprehensive and well-sorted FAQ for future users as I still do believe this device will be booming. (Unless OCZ doesn't fix these "prototype-flaws" and gets beaten by the upcoming Emotiv consumer device)
My first starter at creating a troubleshooting sheet:
(After succesfully installing dotnetfx 2.0 and the NIA software):
1. If device not "connected":
- Check for blue lighting at bottom of box
- Check for correct drivers attached to usb device instance
on Vista (64-bit) systems:
- To reset, unplug USB, reconnect to DIFFERENT usb port (with software still loaded)
2. When getting a 0% flatline .. press headband to forehead. Watch for response
- if response: tighten headband
- if no response: "lube up" (advise to be expanded)
- if still no response: unplug and plug again (try with all cables)
- if still no response: see further
3. When getting 100% flatline
- unplug any adapters or chargers or anything that contains AC/DC converters
- pull headband from head and see if the signal drops
- place headband on tabletop and see if signal registers more than 0%
- touch NIA box to see if signal drops.
- also, does the signal drop-and-rise or stay down while you keep touching
- <various other shielding issues??>
4. When you've gotten a signal line between 0% and 100%
- think of a calm breeze/ocean/white canvas, calm your mind, try for response.
- calibrate, recalibrate, recalibrate (keeping your mind as peaceful as possible)
- <sorry, never got to do this very often>
5. When having an acceptable signal line (yellow) near the baseline/green line,
how to start using the device. A few things I found that worked:
- raising and lowering the eyebrows can be an effective first step to 'muscle'-control
- blinking the left and right eye respectively seem to increase chances of an
intentional 'left' or 'right' glance, though nowhere near perfect.
- jerking the eyebrows up rapidly provided the most effective spikes in muscle switch
- clenching the jaws and gradually increasing pressure allowed a much finer measure
of control over the 'muscle'-joystick
6. Is everything working?
- do you get a signal-reading when touching each sensor separately? should you?
- can you eventually calm all brainfingers (including glance)
- do you see all sensors moving in the "test" screen (without concentration)
- can you center/zero all signals in the "test" screen? (user-specific?)
[Please correct, add, complete the above .. and please cut up and re-place or re-use any of the above text for the creation of a comprehensive FAQ/quick guide]
[On a side-note: where has the "reaction time" practice game gone in the latest NIA software?]
