A wearable interface device, such as a head-mounted display, provides an augmented reality and/or display system and may be used in accordance with medical devices and the performance of medical treatments, particularly a dialysis machine and a dialysis treatment. The wearable interface device may be worn by a user, such as a health care practitioner (HCP), in connection with remotely monitoring and/or controlling the dialysis machine during the dialysis treatment. The HCP may receive alerts and/or other information concerning the dialysis treatment from the dialysis machine that are displayed on the wearable interface device and may use the wearable interface device to control the dialysis machine via the exchange of wireless signals with the dialysis machine. The wearable interface device may recognize commands from the HCP, such as gestures, to provide noncontact operation of the wearable interface device and remote control of the dialysis machine by the HCP.
