Abstract : Over the past decade, more and more elderly people are choosing to live alone. Therefore, in order to provide them with continuous home assistance, the notion of "intelligent home" has emerged. Our aim is to combine three technologies (Bluetooth Low Energy, Audio and LiFi) to provide an efficient and accurate hybrid indoor localization system that locates an elderly person inside a smart home. The principle of hybridization of these three subsystems is based on the combination of their respective results by proposing three new DOP-Like metrics to evaluate "precision" and "accuracy" of the result of each subsystem. This evaluation serves to constitute a weighting of the intermediate results in order to calculate the final position of the target to be localized. Thanks to the introduction of these indicators, the localization error of our system decreased from an average of 0.5m to 0.2m.
