Abstract
A force rendering haptic glove interface is presented that has multiple magnetic actuators positioned on the glove. Each magnetic actuator includes multiple small electromagnetic coils. Multiple positioning sensors are placed on the glove. An external magnetic field generation setup is provided that consists of multiple stationary electromagnetic coils. A controller unit is placed on the glove cuff that receives the position of the sensors and controls the electrical current of electromagnetic coils in the actuators on the glove based on received force feedback data.
Claims6
A force rendering haptic glove interface comprising:
- multiple magnetic force rendering actuators placed on the glove,
- multiple position sensors placed on the glove,
- a controller unit placed on the glove that generates electrical current for the magnetic force rendering actuators based on received force feedback data.
An external magnetic field generation setup comprising:
- multiple stationary electromagnetic coils, installed in different directions,
- generating non-uniform magnetic field between the coils (workspace).
The system of claim 4,
- wherein the position and orientation of each position sensor of claim 1 is received by the controller unit of claim 1,
- the data from the position sensors is sent to a 3D haptic rendering software running on a processing device,
- the 3D haptic rendering software computes the configuration of the glove and estimates the position of each magnetic force rendering actuator of claim 1,
- the 3D haptic rendering software computes required force feedback for each actuator of claim 1 based on the position of the actuator relative to virtual objects in a virtual scene,
- the force feedback data is sent back to the controller unit of claim 1,
- the controller unit of claim 1 is configured to have all the information about the dimension and the exact location of each stationary electromagnetic coil of claim 3,
- The controller unit of claim 1 computes and applies the required electrical current to each actuator of claim 1 using the method of claim 6.
