Abstract
Computing devices (e.g., a smartphone, a smart watch, etc.) may employ ultrawide band (UWB) technology (e.g., signals with a bandwidth higher than 20% of its center frequency, or signals with a bandwidth higher than 0.5 gigahertz (GHz)) to prevent collisions from happening. In some examples, the computing devices may use time-of-flight (e.g., a method for calculating location based on how long it takes for pulses of a signal to travel from one device to another) to determine the distance between the computing devices. Responsive to the distance-based measurements indicating that the computing devices are moving toward each other and within potential collision range of each other, the computing devices may output an alert to warn users of the computing devices of a potential collision. The users of computing devices may then react to the alerts accordingly (e.g., by stopping and looking around) to prevent the collision from happening.
