A system for assessing a patient's visual function includes a first set of electrodes positioned on the patient's scalp, a head-mounted device having a frame with a left eye element, a right eye element, and a bridge coupling the eye elements, light sources accommodated within each of the eye elements, a second set of electrodes integrated in the head-mounted device, and a computing device. When the computing device triggers the one or more light sources to deliver visual stimuli to at least one of patient's eyes, the first set of electrodes records first data and the second set of electrodes record second data. The data is interpreted to differentiate between actual biological causes for visual defects and technical anomalies causing absent or abnormal data in the vision assessment procedure.

A wearable computing device with bio-signal sensors and a feedback module provides an interactive mediated reality (VR) environment for a user. The bio-signal sensors receive bio-signal data (for example, brainwaves) from the user and include bio-signal sensors embedded in a display isolator, having a deformable surface, and having an electrode extendable to contact the user's skin. The wearable computing device further includes a processor to: present content in the VR environment via the feedback module; receive bio-signal data of the user from the bio-signal sensor; process the bio-signal data to determine user states of the user, including brain states, using a user profile; modify a parameter of the content in the VR environment in response to the user states of the user. The user receives feedback indicating the modification of the content via the feedback module.
