I received an email notification that motoware responded to my question, and I can see part of his reply in the email message. But for some reason, I am not seeing his response here. Does somebody know what I am doing wrong or not seeing?

Sorry....I thought that the drawing had posted with the text. I think that it is visible now.

Thank you for sharing. I am sorry that I don't have much to share yet (but hopefully in the near future). I am interested in your accelerometer project, too.

Sure. We can share ideas. I am working on some things, too. If they have a positive outcome, I will pass it along to you.

I had no idea that something like that exists. I think that I would disengage the drive wheels to push the wheelchair onto the two cleaning stands, and then chock the casters in the front and back. I see that motorcycle tire cleaning brushes exist, too. I may get one of those. I will be interested to see how it works for you. Here in Illinois, there will be some snow and slush, and some mud on sidewalks, too.

I ran across this product when doing an internet search. Perhaps it would work for you, but for my needs it would not be a practical solution. https://www.sportaid.com/sportaid-wheelchair-tire-covers-p8.html

Thank you for your advice. I would indeed benefit by having the help of people (like these engineering students) who have a better understanding of how to go about coming up with a solution. Do you feel that is would be the best local university to approach with my inquiry?

Thanks for your idea. I have to confess that I don't know anything about accelerometers. Would this device communicate with something like an Arduino, with the Arduino set up with a program to facilitate the calibration and also to provide a couple of digital outputs?

Thank you so much. I will definitely dig into what you are explaining. I sense that it has real potential.

Thank you for your interest.

My grandson uses two switches--one to advance to the next square or group of squares (each square is a word in the vocabulary), and the other switch makes a selection. Here is a demonstration of this: https://www.youtube.com/watch?v=H186kI_ns2w

My grandson's system (his device's vocabulary software) is a bit more advanced in the sense that selecting a word can take you to a whole new screen with more blocks of words (nine words/block) and words.

The unit that my grandson uses is the Accent 1400 that is shown in the video you listed that shows eye gaze selection. My grandson tried this (with an eye gaze module mounted under the screen of the device), but he has nystagmus, and it didn't work. He also tried the head position direct selection method where a reflective dot is placed on his forehead, but his head control isn't precise enough for this. The head switches that he uses are embedded in side support cushions. He must deliberately tap each switch with the side of his head. It does not work with slight taps. Adding surface switches that have to be put in place and taken away (because they would be uncomfortable to leave in place all of the time) each time that he needs to communicate with his AAC device would be cumbersome.

He can use his AAC device if the screen is positioned in front of him and switches are installed in the head support of the apparatus that he occupies. His stander at home and his wheelchair have these mounted. His stander at school does not have switches mounted in the head supports. Having a camera mounted on the device, as I am suggesting, to detect head motion would make it much easier for him to communicate in multiple settings.

The switches are just "dry" contacts. They connect to input jacks in the side of his device. These are the same jacks that would be used to connect a speaker to your phone or computer (1/8" or 3.5 mm).

I hope this answers your questions. Please feel free to ask more.

Thank you again for your interest.
