Leather pens tiffany

We have an NEC projector at the church and I want to put buttons on Pastor's pulpit for control . Any ideas? - ethernet projector

We are a small church and the pastor is VERY techy. I would find a way to hard to have 5 buttons on the chair so they do not extend your arms and infrared remote control.
ON
OFF
Computer 1 (for the worship team Easy)
Computing 2 (Laptop Pastor)
Video

There is someone out there has this problem? I Ethernet projector in the chair if necessary.

Thank you,
Eric
