Another idea is one I recently discovered. Visit a VA hospital and if you are a Computer Programmer/Computer Tech, think about donating your services to help the Paralized Vets.
Build them computers, program the computers with assistive programs so they can reach out to the world and communicate.
After my visit, I came home convinced I have been living in la-la land never realizing so many needed our help, and began right away building, programming and providing free computers to the very deserving disabled. Good used computers can be purchased off eBay and other auction sites if you don't want to build one. There are also a lot of free assistive programs to download from the internet.
Many of the Paralized Vets can't even use a telephone. I installed voice control and MagicJacks and saw smiles all over the place for those guys! If they had to buy an assistive phone, they run between $600 and $1200 for those phones, which few to nobody can afford. A computer can be programmed to handle everything those people need for cheap to free. If they have no voice, the computer can be programmed to provide a computerized voice for them with just a joystick and keystrokes -- or a blow pipe.
They can watch tv on their computers, control the channels, volume -- everything. I can't think of any communication, or non-medical interaction they need that the computer can't be programmed to do for them, even turning off their lights and checking that all their doors are locked at night. As well, entertainment and physical therapy are both computer related assistive technologies now.
So much can be done to help. How about the guy who once loved to bowl, or the guy who once loved to fish and now they are sitting in wheelchairs or stuck in bed not able to do anything, and along you come one day with a Wii or a computer, and suddenly they are bowling and fishing with the Wii, and talking to their friends and loved ones with free long distance via that MagicJack you hooked into a voice activated computer for them. And, Physical Therapists are seeing miracles in their once resistive patients.
Just think about it. Step up to the plate if you can do so.
