INFORMATION AND COMMUNICATION TECHNOLOGIES AIMING AT THE REDUCTION OF THEIR OWN ENERGY USE ## Abstract Embodiments include techniques for contextual switch from a wireless communication to human body near-field communication for power savings, the technique includes determining, via a processor, a configuration of devices for a user, the devices include wearable devices and mobile devices. The techniques include identifying a cluster of the devices, and determining a current activity and location of the user based on an indication from at least one of the devices. The techniques also include determining a proximity of the devices to the user, and based on the current activity, the location, and the proximity of devices, switching one or more connections to of the devices from a wireless communication technology to a human body near-field communication. The techniques include storing the configuration and the activity of the user. ## Claims ### Claim 1 A computer-implemented method for contextually switching from a wireless communication to human body near-field communication for power savings, the method comprising: determining, via a processor, a configuration of devices for a user, the devices include wearable devices and mobile devices;
