Abstract
A system may include an electromagnetic load capable of generating a haptic event and a haptic processor configured to receive at least one first parameter indicative of a desired perception of the haptic event to a user of a device comprising the electromagnetic load, receive at least one second parameter indicative of one or more characteristics of the device, and process the at least one first parameter and the at least one second parameter to generate a driving signal to the electromagnetic load in order to produce the desired perception to the user despite variances in the device that cause an actual perception of the haptic event to vary from the desired perception.
Claims16
A system comprising:
- an electromagnetic load capable of generating a haptic event;
- a haptic processor configured to:
- receive at least one first parameter indicative of a desired perception of the haptic event to a user of a device comprising the electromagnetic load, further wherein the at least one first parameter is indicative of a desired acceleration of the device:
- receive at least one second parameter indicative of one or more characteristics of the device;
- and
- process the at least one first parameter and the at least one second parameter to generate a driving signal to the electromagnetic load in order to produce the desired perception to the user despite variances in the device that cause an actual perception of the haptic event to vary from the desired perception;
- and
- a waveform generator configured to generate a driving waveform based on the desired acceleration.
A method comprising:
- receiving at least one first parameter indicative of a desired perception of a haptic event to a user of a device comprising an electromagnetic load capable of generating the haptic event, further wherein the at least one first parameter is indicative of a desired acceleration of the device;
- receiving at least one second parameter indicative of one or more characteristics of the device;
- processing the at least one first parameter and the at least one second parameter to generate a driving signal to the electromagnetic load in order to produce the desired perception to the user despite variances in the device that cause an actual perception of the haptic event to vary from the desired perception;
- and
- generating a driving waveform based on the desired acceleration.
