Abstract
Systems and methods for ultrasonic collision management in virtual, augmented, and mixed reality (xR) applications are described. In some embodiments, an Information Handling System (IHS) may include a processor and a memory coupled to the processor, the memory having program instructions stored thereon that, upon execution by the processor, cause the IHS to: execute an xR application to display an xR image to a user of the IHS; and detect, via an ultrasonic sensor coupled to the processor, a potential physical interaction between the user and a physical object during execution of the xR application.
Claims17
An Information Handling System (IHS), comprising:
- a processor;
- and
- a memory coupled to the processor, the memory having program instructions stored thereon that, upon execution by the processor, cause the IHS to:
- execute a virtual reality, augmented reality, or mixed reality (xR) application to display an xR image to a user of the IHS;
- detect, via an ultrasonic sensor coupled to the processor, a potential collision between the user and a physical object during execution of the xR application by comparing a position, a velocity, and an acceleration of the user with a position, a velocity, and an acceleration of the physical object;
- and
- in response to the ultrasonic detection, instruct the user to lay down or stand up to cause the collision using haptic system coupled to a user's vest or backpack, wherein the haptic system comprises haptic circuitry configured to control four haptic actuators located in the front, back, left, and right of the user using a set of digital-to-analog converters (DACs), piezo-driving circuitry coupled to the DACs, and flyback circuitry coupled to the piezo-driving circuitry that controls a vibration of at least one of the haptic actuators, and wherein (a) if a distance between the user and the physical object is above a threshold value, decrease at least one of:
- an intensity of the vibration or a frequency of the vibration, and (b) if the distance is below the threshold value, increase at least one of:
- the intensity of the vibration or the frequency of the vibration.

A method, comprising:
- executing a virtual reality, augmented reality, or mixed reality (xR) application that displays an xR image to a user wearing a headset;
- detecting, using an ultrasonic sensor, a potential collision between the user and a physical object during execution of the xR application by comparing a position, a velocity, and an acceleration of the user with a position, a velocity, and an acceleration of the physical object;
- and
- in response to the ultrasonic detection, instructing the user to lay down or stand up to cause the collision using a haptic system coupled to a user's vest or backpack, wherein the haptic system comprises haptic circuitry configured to control four haptic actuators located in the front, back, left, and right of the user using a set of digital-to-analog converters (DACs), piezo-driving circuitry coupled to the DACs, and flyback circuitry coupled to the piezo-driving circuitry that controls a vibration of at least one of the haptic actuators, and wherein (a) if a distance between the user and the physical object is above a threshold value, decrease at least one of:
- an intensity of the vibration or a frequency of the vibration, and (b) if the distance is below the threshold value, increase at least one of:
- the intensity of the vibration or the frequency of the vibration.
