Abstract

The present disclosure provides systems and methods associated with determining velocity and/or acceleration information using ultrasound. A system may include one or more ultrasonic transmitters and/or receivers. An ultrasonic transmitter may be configured to transmit ultrasound into a region bounded by one or more surfaces. The ultrasonic receiver may detect a Doppler shift of reflected ultrasound to determine an acceleration and/or velocity associated with an object. The velocity and/or acceleration information may be utilized to modify the state of a gaming system, entertainment system, infotainment system, and/or other device. The velocity and/or acceleration date may be used in combination with a mapping or positioning system that generates positional data associated with the objects.
