  • Publication number: 20180023334
    Abstract: Technologies are generally described for activation of actuators based on sensed user characteristics, such as orientation. In some examples, an access control system may be configured to activate an actuator upon determining that an activation device is both in proximity to and has a similar orientation to the actuator. The access control system may be configured to determine orientation similarity by determining an orientation associated with the activation device, determining an orientation associated with the actuator, and comparing a difference between the two orientations to an activation threshold. The actuator may be associated with an entryway such as a building doorway, a room doorway, or a vehicle door, or may be associated with a container such as a safe or vehicle trunk.
