Abstract
Systems and methods are provided for generating haptic effects adapted to a dynamic system associated with a user's dynamic interaction with a haptic enabled apparatus. The systems and methods operates to monitor a dynamic change in the dynamic system and automatically modify haptic rendering in real time so that the user can feel consistent haptic effects adapted to the change in the dynamic system.
Claims36
A method for generating a haptic effect, the method comprising:
- receiving a signal from an input device of a haptic enabled apparatus, the signal representative of one or more parameters of a dynamic system including object parameters representative of physical characteristics of the haptic enabled apparatus which influence a user's sensation of a haptic effect generated from the haptic enabled apparatus;
- determining a haptic parameter modification value based on the signal;
- modifying at least one of haptic data parameters based on the haptic parameter modification value;
- generating a modified haptic signal based on the haptic data parameters;
- and
- applying the modified haptic signal to a haptic actuator, thereby providing a haptic effect adapted to the dynamic system.
