Piano Stairs/Floor Answered

Hi all!
Just saw the infamous "piano stairs" video by Mitsubishi (see below), and I couldn't help but think there would be a relatively easy way to do this yourself without a ridiculous budget.
Any ideas on how this could be done? I thought some sort of infrared sensor would be cheaper than a pressure sensor like in the video, and could be connected to a computer or device with speakers, or maybe a speaker for every stair with a simple circuit. Then again, I haven't a clue about anything DIY.

Any ideas?

Our company ( http://www.thePianoStairs.com ) is developing piano stairs in all over the world. We recommend neither infrared sensors nor pressure sensors.

What do you recommend instead?

Using infrared sensors instead of pressure triggers is a great idea --less wear and tear, especially in that high-traffic setting. Perhapshouse them in transparent cases in a recess in the wall, to protect theelectronics. You'll probably want to consult an Instructable about usingan Arduino to read the infrared interrupts as notes, like on an electrickeyboard. Reverse-engineering it shouldn't be that difficult.

Depends what you use for pressure sensors. You could put cheap strain gauges under the stairs, if you have access for example.

I am actually thinking about finding a casio keyboard and just adding the needed wires to shock sensors in the florr. then they can turn it off/ on and change the sounds as well. My mom loves to play the piano and will undoubtedly use my stepfather to help her play chords(that sounds wrong when i type it but oh well..)

Search instructables for the many DDR video game dance pad footcontrollers.  That should give you some ideas for large scalepressure switches on the cheap.  I have always wanted to make thegiant piano they played on the movie BIG with Tom Hanks at FAOSchwartz.  Good luck.

good i dea, i made a joke about getting a set for my mom in thier new home ad now she and my step father wants one. So i am going to have to deliver.
