The Hitchhiker's Guide to Fused Twins -- A Conceptualization to Access Digital Twins in situ in Smart Cities

Dense Indoor Sensor Networks: Towards passively sensing human presence with LoRaWAN

“…Sensor data is delivered by the SoA middleware EVEREST to DAVE. The Fused Twins paradigm [27] is applied to display the data in its spatial context in the original building [26]. Source: Image is modified from [32] with permission.…”

“…The software Data Analytics in Virtual Environments (DAVE; see Fig. 6(b)) can be used to explore either the DT on a screen or using an AR HoloLens to access the FT representation of the data in situ [26,27]. Because readings from any single sensor would be difficult to interpret, a Building Information Model (BIM) in DAVE provides a spatial context for the densely placed sensors.…”

“…A DT is a platform for digitally mirroring processes from the physical world [21][22][23] that is suitable for continuously evaluating human presence indoors [24] and to study human building interaction [25]. DTs can be visualised in Augmented Reality (AR) with the Fused Twins (FT) paradigm [26,27] by which the data is brought back into the physical twin to be placed in situ where they were recorded.…”
