PROXIMITY-BASED SETTINGS AND FUNCTIONALITY

A first computing device (e.g., a smart speaker, a smart television, 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 locate a second computing device (e.g., a smartphone, mobile phone, a tablet computer, a laptop computer, a wearable device, etc.) in order to automatically perform various actions based on the distance (and, optionally, relative position) between the first computing device and the second computing device. In some examples, the first computing device may use time-of-flight to determine distance between the first computing device and the second computing device. In some examples, the first computing device may select one or more actions to perform based on attributes (e.g., interests, preferences, settings, child or adult, etc.) of the user of the second computing device and the distance between the first computing device and the second computing device. For example, the first computing device may start audio playback of the user’s favorite songs when the second computing device is close to the first computing device (e.g., within 10 meters (m)) and stop audio playback when the second computing device is far from the first computing device (e.g., further than 10 m)
