peripheral vision feedback device

[Guest guest]

hi millie and group,

thank you for your interest. i finished the device just two months ago and only

trained myself with it so far. just these days i am starting nfb with clients.

so what i can tell is limited. i uploaded some pictures of the device on my

website, they are here:

http://www.draladesign.de/fotos/peripheralfeedback/

in my experience it works quite well to shift from foveal seeing to peripheral

vision, and there is a definitite relaxation response just from getting the

feedback in peripheral vision. the feedback also shifts the brain in the desired

direction. for allmost all eyes open training i do i use the peripheral

feedback, not because i force myself but because i like it. it feels light and

good and relaxing. but i have to say as a meditator i am accustomed to not much

happening in the outside. i dont know how hyperactive kids would do with this

kind of feedback. in the beginning of training i had longing after a few days

without training for this kind of feedback. during the last months my vision

habits changed, now i see more of my surroundings then before. when you drive

the same way to your workplace and suddenly you see much more of the

surroundings, something must have changed.

the device uses the audio output jack of the computer. in bioexplorer, you set

up tongenerators and different audioplayers playing in different frequencies for

each feedback threshold. as an example, if you have a two inhib one reward

protocol, you could connect the reward to one tongenetor and play a 150hz sinus

tone over that channel. the first inhib you could play 500hz, the second 1000hz.

the device has frequency filters which analyses the incoming signal. the filters

are matched to the output frequencies of the tongenerator or audioplayer ( for

these i recorded an mp3 file of a sinus tone). if a 150hz signal comes in, the

150hz frequency filters lets it through, it gets amplified by a transistor and

then sent to an arduino, a microcontroller board. the arduino measures the the

incoming signal on his analog input pins and will then turn on or off the leds.

on the board are 4 filters for each one of the two audio channels( stereo).

theoretically there would be 8 different independent feedback possibilities.

however, bioexplorer can just handle 7 output signals at a time, like 3

different tone generators and 4 audioplayers. if there are more they disturb

each other.

you can also use one or two channels for tactile feedback. a little vibration

motor from a mobile phone in a small plasik box which you can put in your pocket

or under the shirt on your shoulder.

you also have the possibility of using just one channel of the stereo output for

peripheral vision and the other you can use for classical audio feedback. so you

can combine the peripheral vision feedback with sound feedback.

for example if there is too much slow activity in the front and hypercoherence,

you could sqish the slow activity with audio feedback and give feedback for the

coherences in the peripheral vision. if there is beta reversal you might even

add a beta reward in f3.

one thing which is interesting about the peripheral feedback is that you can

train more things at a time without setting the thresholds to 90% or more reward

time. since there is always one or two leds going on and off, you dont get

frustrated. if in audio or video feedback it always stops an starts, it is

frustrating. the instruction with peripheral vision feedback is to make as much

leds light as possible.

i did test this with an 4 ch alpha synchrony protocol. it works fine.

but i would love to hear what the more experienced people think of training many

things at a time, like amplitudes and coherences.

in the z score training, you train up to 100 values at a time, with just one

feedback. the rewarded values change from second to second, depending on which

ones are in the training window, and it seems to work.

on the other hand i can understand it is more difficult to find the matching

protocol for the client since it is more complex. he might response well to slow

activity sqish but not so much to coherence down. if you train both at the seme

time, what is the outcome?

i would be happy for feedback and critique. this would help to develop this idea

further, thank you.

Hi ,

Thanks for sharing your innovative device and giving a detailed description. I

am truly impressed with your ingenuity and ability to think outside of the box.

Have you patented it yet? Do you have plans to market it? Please keep us

posted on your amazing work and if you need any people to test drive it, I'd

surely be interested. Best of luck!

Best wishes,

Millie
