Voice Controlled Power Wheelchair - 3rd Party Testing

[alkapowow786]

I have ordered this chip, and the voice recognition eval library off MicroChip. It appears i have to programme it by C programming. Could anybody help me. Is there any way of programming this by MP LAB, Assemmbly?

I dont know enough about C programming, isit still a fairly easy job programming the library?

Very interesting

i really like the wheel chair, you said you have incorporated that using DSP, can you help with the programming?voice controlled wheelchair is also my thesis so im searching for person whom had knowledge of it...i hope you can help me... by the way my name is jerry from philippines

I am glad to see you have taken an interest in my project. I completely understand your comment about standing out when humming. As far as I know the other options for control are:

1. Head Array (if you have movement in the neck)

2. Sipp&Puff (sucking and blowing on a straw!)

* I don't think the humming is worst than sipp&puff.

About your other comment:

I do have that kind of turning or general movement. You can say "Go Right, Speed 3" or "Go Reverse, Speed 4" with no need to hum.

@8HoSsEiN8 ARE YOU LOOKING FOR

ANY MORE POWER WHEELCHAIR

TESTERS.

I AM LOOKING AND WILLING TO

LIVE ANYWHERE.

Outstanding! Have you been able to incorporate a steering option while going forward? Let's say as you are going forward you say, "Right" and turns right by 2 degrees. Steering on the fly would be great. If I were in a wheel chair and had to hum to get it to turn I might feel a little embarassed. What about increasing the speed in turning a bit. The biggest turn would only be 180 degrees. The user would get used to its' speed and know when to say stop. Just like learning how to stop a car.

1ManClan,

About steering while going forward, yes it would be no problem! I can easily incorporate this type of control.

About the humming comment, I would say that the humming is for short distances and for a complete smooth control!

Please note that I have 2 types of control on the chair: 1. Manual and 2.Smooth Control: In manual mode you can change the speed with a speed command for faster turns. In smooth control mode frequency of the humming is translated in to the speed.

I need you to imagine being that person in the wheelchair in public. I spoke with some of my co-workers and we work with both children and adults. The LAST thing that they want is to stand out MORE in public places. One of the comments that I recieved from a client is that humming would be embarrassing. How about if you incorporated degree turning? You say, "Turn right 43 degrees"? The speed of the turn would be based on number of degrees. The higher the number, the higher the speed?

Very cool. looks simple enough for self installations

[8HoSsEiN8]

Thanks for your comment!

The board for voice control is a custom designed board, so I'm not sure how easy it is to self install. However, if you had the all hardware ... yes its integration to the original controller is relatively easy.

The only issue is what about people who have speech problems?

This project was started knowing that many disabled individuals have very limited motor functions in their hand (to use joystick controller) or neck (to use head array controller) so, they have to use a Sipp'n Puff controller which is usually uncomfortable.

In general, my controller was designed for these patients. If they can't talk, it is possible to have them control the chair only through humming at different frequencies and durations.

interesting... i really dont like the idea of sip and puff controllers... to me i codenamed it... the french kisser 3000... and who wants to french kiss their powerchair hhahahah...

i might want to do a test run with you guys... anywhere near chicago? we could really get this thing off the ground...

[8HoSsEiN8]

lol ... french kiss!

We are in Virginia, George Mason University. You are more than welcome to do a test run if you ever visited us.

What do you do yourself? I am a grad student and this is my thesis I'm working on. Its a work in progress and I'm planning to add more features to my controller.
