Samsung patents Wi-Fi signal method to detect if devices are in same room

Samsung describes a method where a device checks the strength of nearby Wi-Fi signals to guess if other devices are in the same room. The system uses a model to make this estimate and then improves its accuracy by learning from user feedback and filtered signal data.

Why it mattersThis could help phones automatically adjust settings, like lowering volume or pausing media, when they detect other people or devices are nearby without needing direct communication.

In the filing’s own words

An embodiment may provide a method including: obtaining a first Wi-Fi RSSI corresponding to Wi-Fi networks communicable with the user device; obtaining second Wi-Fi RSSIs corresponding to Wi-Fi networks communicable with other devices; estimating, by applying the first Wi-Fi RSSI and the second Wi-Fi RSSIs as input data to a copresence estimation model, an estimation result indicating whether the other devices are present in a same space as the user device; receiving feedback based on the estimation result; generating, based on the feedback, a feedback dataset including the first and second Wi-Fi RSSIs; obtaining a pre-collected first Wi-Fi RSSI corresponding to the Wi-Fi networks communicable with the user device; obtaining pre-collected second Wi-Fi RSSIs corresponding to the Wi-Fi networks communicable with the other devices; generating, by filtering the pre-collected first and second Wi-Fi RSSIs, a filtered dataset; and updating, based on the feedback and filtered datasets, the copresence estimation model.

What exactly they claim (claim 1)

1. An method of operating a user device, the method comprising: obtaining a first Wi-Fi Received Signal Strength Indicator (RSSI) corresponding to one or more Wi-Fi networks that are in position to communicably connect with the user device; obtaining a plurality of second Wi-Fi RSSIs corresponding to one or more Wi-Fi networks that are in position to communicably connect with one or more other devices; estimating, by applying the first Wi-Fi RSSI and the plurality of second Wi-Fi RSSIs as input data to a copresence estimation model, an estimation result that indicates whether the one or more other devices are present in a same space as the user device; receiving feedback based on the estimation result; generating, based on the feedback, a feedback dataset comprising the first Wi-Fi RSSI and the plurality of second Wi-Fi RSSIs; obtaining a pre-collected first Wi-Fi RSSI corresponding to the one or more Wi-Fi networks that are in position to communicably connect with the user device; obtaining a plurality of pre-collected second Wi-Fi RSSIs corresponding to the one or more Wi-Fi networks that are in position to communicably connect with the one or more other devices; generating, by filtering the pre-collected first Wi-Fi RSSI and the plurality of pre-collected second Wi-Fi RSSIs according to preset conditions, a filtered dataset; and updating, based on the feedback dataset and the filtered dataset, the copresence estimation model.
