Abstract
One illustrative system disclosed herein includes a computing device that comprises a memory and a processor in communication with the memory. The system also includes an xPC target machine that is capable of achieving sampling rates of at least 100 khz and in communication with the computing device and a user device that includes a sensor and a haptic output device. The processor generates a simulate reality environment and determines a haptic effect based on the simulated reality environment or a sensor signal from the sensor. The processor transmits data about a parameter of the haptic effect or the sensor signal to the xPC target machine, which determines the parameter of the haptic effect and generates, in substantially real time, a haptic signal. The xPC target machine transmits the haptic signal to the haptic output device, which is configured to receive the haptic signal and output the haptic effect.

2. A computing device comprising:
a processor and a non-transitory computer-readable medium communicatively coupled to the processor, wherein the processor is configured to execute processor executable instructions stored in the non-transitory computer-readable medium to; generate a simulated reality environment; obtain data indicating a parameter of a haptic effect associated with the simulated reality environment; determine, based on the parameter of the haptic effect, whether the haptic effect is a static haptic effect or a dynamic haptic effect; determine, based on the parameter of the haptic effect, whether the haptic effect is a periodic haptic effect or an aperiodic haptic effect; generate, in substantially real time as the processor receives the data about the parameter of the haptic effect, a haptic signal associated with the haptic effect, wherein the processor is capable of processing the data about the parameter of the haptic effect at sampling rates of at least 20 kHz and generating the haptic signal that has a frequency between substantially 1 Hz and 20 kHz; and transmit the haptic signal associated with the haptic effect to a haptic output device. - View Dependent Claims (3, 4, 5, 6, 7, 8)

9. A method comprising:
-
generating, by a processor, a simulated reality environment; obtaining, by the processor, data indicating a parameter of a haptic effect associated with the simulated reality environment; determining, by the processor and based on the parameter of the haptic effect, whether the haptic effect is a static haptic effect or a dynamic haptic effect; determining, by the processor and based on the parameter of the haptic effect, whether the haptic effect is a periodic haptic effect or an aperiodic haptic effect; generating, by the processor and in substantially real time as the processor receives the data about the parameter of the haptic effect, a haptic signal associated with the haptic effect, wherein the processor is capable of processing the data about the parameter of the haptic effect at sampling rates of at least 20 kHz and generating the haptic signal that has a frequency between substantially 1 Hz and 20 kHz; and transmitting, by the processor, the haptic signal associated with the haptic effect to a haptic output device. - View Dependent Claims (10, 11, 12, 13, 14, 15)

16. A non-transitory computer-readable medium comprising processor-executable program code configured to cause a processor to:
-
generate a simulated reality environment; obtain data indicating a parameter of a haptic effect associated with the simulated reality environment; determine, based on the parameter of the haptic effect, whether the haptic effect is a static haptic effect or a dynamic haptic effect; determine, based on the parameter of the haptic effect, whether the haptic effect is a periodic haptic effect or an aperiodic haptic effect; generate, in substantially real time as the processor receives the data about the parameter of the haptic effect, a haptic signal associated with the haptic effect, wherein the processor is capable of processing the data about the parameter of the haptic effect at sampling rates of at least 20 kHz and generating the haptic signal that has a frequency between substantially 1 Hz and 20 kHz; and transmit the haptic signal associated with the haptic effect to a haptic output device. - View Dependent Claims (17, 18, 19, 20)
