Technology for virtual reality device for avoiding collisions during a virtual reality experience. The virtual reality device comprises an accelerometer configured to sense an acceleration of the virtual reality device and a gyroscope configured to sense an angular velocity and orientation of the virtual reality device. Further comprising one or more proximity sensors configured to detect an object. A processor may be configured to receive data from the one or more proximity sensors and predict a potential collision between a user of the virtual reality device and the object detected by the one or more proximity sensors. An alarm may generate an alert regarding the potential collision.
