That is a very difficult question to answer. Some people are more into tech than others. Some people may not be able to afford the tech that they want or need. Others may have government or agency funding for devices to assist them. Most devices are not purchased every year but are significant purchases. A braille display or notetaker will last for a number of years and if a person is relying on government funding they may only be eligible every X number of years. Some people will have subscription services like Aira which will be easier to track yearly.

Finally, I will say that there are devices that use universal design. I have an iPad, iPod, MacBook and iPhone. In another person's hands these would not be assistive devices but when I turn on accessibility features they become that.

Okay, so after I have given all my reasons why it is difficult to calculate I will give a number of $2500-$3000 per year on average. It is pretty much a guess since my purchases are sporadic. Others may have better numbers.

I don't spend money when I can get apps for free. I spent money on my IPhone and laptop but I use free screen readers on them. I use mostly free apps for my Iphone and my laptop so i don't spend money on that kind of stuff. I think if you're not in school or college and don't want or need a braille display, the amount of people buying this kind of stuff is going to be cut hugely compared to say 10 years ago.

I’d say it averages about $1000/ year. Some years I spend more, some less. The big purchases are only ocassional.
