Trying to help stroke victim dad get back into his hobbies

hi, my name is Ronan and my dad had a stroke a couple of years back. He is the most lively person you’ll ever meet even with the disabilities he has. He was an IT business owner before his stroke and was a huge gamer. Since his stroke, he has sadly lost any movement in his left side no matter how much therapy we have tried. Due to this, he is home 24 hours of the day and is unable to really have any active hobbies. With his background in gaming, he loves to try and play games as that is the only thing he enjoys to pass the time. With no ability in moving his left side, it’s hard to play the games he used to love playing. I am hoping to raise funds to get him a custom hand keyboard and a mouth controller for this Christmas which can help him play the games he once enjoyed and to have something he can do at home to pass time instead of just sitting around. Any help would be much appreciated.
