She uses her iPad with her nose - so she's using a remote desktop app to connect to her Mac laptop, in turn using the iRed software to control an IR box, which then controls the TV, Amplifier, and the fan.
Say goodbye to the ugly accessibility remote control boxes!
Step 1: Get an IR box
Lyn uses the IR Trans, USB v3.6 as pictured.
Having typed into Google and had a quick look, I believe she's using this one:
IRT-USB-Mac IRTrans USB Device incl. iRed license for the Mac 99,00 EUR Export price excl. VAT 83,19 EUR
Can be found here:
Step 2: Get iRed up and running
Download iRed, and set it up so that you can control your TV, fan or indeed anything with IR controls, directly from your mac.
I don't know any more than this yet, but let me know, and I'll ask Lyn for more deets if you need.
Step 3: Get Remote Desktop app
The one Lyn was using is a paid app, called "Desktop Connect" - it worked for her.
Connect this via the wifi router to the Mac (I assume)
