Abstract

The invention relates to a method for enabling contact tracing and contact alerting among a plurality of persons by means of detecting or measuring the distance between two persons, wherein each of the plurality of persons are wearing or carrying a wearable or portable device, the wearable or portable devices having or being associated or assigned to, respectively, a tag identifier, the tag identifiers being repeatedly broadcast by the wearable or portable devices, respectively, using a wireless communication interface of the wearable or portable devices,wherein, in a contact situation of a specific wearable or portable device with a specific further wearable or portable device, the wearable or portable device is able, by means of the wearable or portable device's wireless communication interface and with respect to the further wearable or portable device, to repeatedly determine the distance, at different points in time, towards the further wearable or portable device and to receive the further wearable or portable device's tag identifier,wherein, in order to detect alert situations and/or in order to detect relevant encounters or to assess the relevance of encounters of the wearable or portable device with the further wearable or portable device, the method comprises the following steps:-- in a first step, at least one proximity event involving the further wearable or portable device, and detected by the wearable or portable device, is determined by means of detecting the further wearable or portable device to be positioned at most at, or below, a specific distance, from the wearable or portable device, and this for at least a specific time interval, wherein the proximity event is considered to be an encounter detection event if the specific distance corresponds to a risk distance threshold and the specific time interval corresponds to a risk time interval and/or wherein the proximity event is considered to be an alert event if the specific distance corresponds to an alert distance threshold and the specific time interval corresponds to an alert time interval,-- in a second step, prior to, during or after the first step, the wearable or portable device additionally, detects or receives-- a group size information, the group size information being indicative of the relevant group size and/or of the relevant density of persons, and/or-- an environmental information, the environmental information being indicative of a static and/or dynamic environmental parameter or property,wherein the risk distance threshold and the risk time interval and/or the alert distance threshold and the alert time interval to be applied are dependent on the group size information and/or on the environmental information.
