For people with severe disabilities who do not suit with conventional wheelchair driving systems, like the manual ones or the electric with joysticks, for example; alternatives and solutions have been researched, leading to a proposal that has been developed based on an interface that simulates the control of a wheel-driven platform, such as a whee...

... the implementation, we designed the input value of our robotic system from the previous packages; also defining two operating modes to make the most of these inputs and to have a more controlled operation, so that nothing is disturbed unintentionally. This means that the diverse entries can have different roles depending on the operating Their interpretation is possible thanks to a face feature detection simplified mediapipe face landmarks model, which provides the keypoints shown in the Figure 1b. Then, a reference axes are defined with four of the available landmarks, in such a way they halves the face horizontally and vertically, finally dividing it into four quadrants (as shown in the Figure 1c). ...

Then, a reference axes are defined with four of the available landmarks, in such a way they halves the face horizontally and vertically, finally dividing it into four quadrants (as shown in the Figure 1c). When the user moves the head, these quadrants dimensions change, and these changes can be used to scale variables as entries for the control system. ...
