Definitions
- a still further aspect of the present invention is to offer a touchpad controller, which can be mounted at any angle to suit the driver's needs.
- a first voltage V1 is applied across lower semi- conductive layer or resistive film 22 between terminals 30 and 31
- a second voltage V2 is applied across upper semi-conductive upper layer or resistive film 28 between terminals 32 and 33.
- the direction of current flow, and hence the direction of the voltage gradient in film 22 is substantially orthogonally oriented with respect to the currently flow and voltage gradient in film 28. Therefore, if sufficient pressure is applied to cause semi-conductive layers 22 and 28 to contact each other, then voltages which correspond to the X and Y coordinates of the contact location will be transmitted to those semi-conductive surfaces.
- the touchpad of the present invention is a proportional speed and direction-controlling device.
- the further one's finger is from the neutral point, the electrical resistivity is less with regard to that region and thus corresponds to a proportionally larger electrical voltage signal which is sent to the motor with regard to speed and direction.
- the wheelchair responds and moves in a direction analogous to the finger movement on the touchpad and at a speed which corresponds to a distance from the neutral point of the touchpad. This is because the contact between the layers completes a circuit giving both X and Y coordinates which correspond proportionally to the direction and propor- tionally to the speed of the wheelchair.
