Good afternoon
First, my humble apologies if this project has already been mooted and I simply can't find it, and further if this is not the correct place or method to ask this type of question
I have been undertaking therapy of a type called EMDR - Eye Movement Desensitization and Reprocessing. At its roots, this involves bi-lateral stimuli, left-right patterns of light, sound and vibration
The machine my therapist uses was expensive for her to import and I have a number of ideas for how to improve it. I have been working with a lights solution at work written using Adafruit Neopixel libraries on a Duemilanove / Diecimelia so I think I would be OK with the coding aspects of the project but this would be my first foray into hardware.
Looking around there are a baffling number of boards and shields and I simply don't know what to look for - I am hoping a kind soul here might be able to offer advice.
I need to drive approximately 2 meters of programmable LED (I can reduce this by changing the way the sequence plays), output alternating sounds to headphones (so 2 channel) with the ability to change the pitch and alternate two tactile outputs. Finally I would need some way for the end user to be able to interact with the program - this could be IR, Bluetooth or other radio or worst case wired.
I would be exceptionally grateful if someone might be able to suggest the direction(s) I should look first, in terms of what board and shield(s) I should look into.
Thank you very much for your time

It would help to know more about what sort of user interaction is required -- are you looking for a settings U/I or a joystick or buttons for the "subject" as part of the therapy?
Also think about the type of sounds required. Any old Arduino can generate simple tones, but if you need specific sounds -- recorded or generated -- you will likely want a faster ARM based system with lots of memory. If tones is all you need, have a look at:
If you need complex sounds, then maybe an MP3 playback module could be useful, though very exact (sub 300ms) timing of sounds might be challenging. The Open Music Lab has numerous sound handling methods documented that could help you.
Looking at the "EyeScan" systems, I think a string of addressable neopixel style LEDs would be ideal and the hardware and software requirements to drive that part is minimal. The Adafruit examples require not much more than a power supply and a resistor to drive the strips.
