A HANDS GESTURE SYSTEM OF CONTROL FOR AN  
 INTELLIGENT WHEELCHAIR  

When  an  unfortunate  event  affects  the  motor  capacity  of  a  person,  it  is necessary to use devices like wheelchairs that offer a means o displacement for patients with motors problems of the lower limbs.

Some patients that cannot manipulate the wheelchair with their arms due to a lack  of  force  or  psychomotor  problems  in  the  superior  members,  request electric  wheelchairs,  frequently  manipulated  with  joysticks;  however  the joystick  manipulation  is  even  not  practical  and  frequently  it  must  be  handle with the mouth.  

The  present  article  presents  the  partial  results  in  the  development  of  a wheelchair  controlled  by  an  intuitive  interface,  where  the  instructions  are given by hand gesture instructions.  

The advances are presented in the realization of the control software using a Webcam  and  some  distances  and  presence  sensors  controlled  by  a  PIC microcontroller that establishes the communication with a program developed in Labview.
