A method of rendering virtual content comprises capturing an image of a field of view of a user, extracting a set of map points based on the captured image, recognizing an object based on the extracted set of map points, retrieving semantic data associated with the recognized object and attaching the semantic data to object data associated with the recognized object, and inserting the recognized object data and the semantic data attached thereto into a virtual world model such that virtual content, when rendered at a user device of the user, is displayed in relation to the recognized object.

The present disclosure relates to a bioelectrical signal acquisition device, an interactive system, and related methods. The bioelectrical signal acquisition device includes a series of electrodes that are configured and positioned to effectively record bioelectrical signals from a user's head. The interactive system and related methods can be used to collect, display, and analyze the bioelectrical signals, especially signals related to sleep. The device, system, and methods can also be applied to modulate physiological or pathological conditions of the user.

Configurations are disclosed for a health system to be used in various healthcare applications, e.g., for patient diagnostics, monitoring, and/or therapy. The health system may comprise a light generation module to transmit light or an image to a user, one or more sensors to detect a physiological parameter of the user's body, including their eyes, and processing circuitry to analyze an input received in response to the presented images to determine one or more health conditions or defects.

An example system disclosed herein for transforming neuro-response data into media ratings includes a data collector to obtain first neuro-response from a first subject exposed to a first media and second neuro-response data from a second subject exposed to a second media. The first media broadcast is before a time of the second media. The example system includes an analyzer to integrate the first neuro-response data with ratings data for the first media to generate a first rating for the first media. The ratings data is based on set-top box data associated with a media presentation device presenting the first media. The analyzer is to transform the second neuro-response data into a second rating for the second media based on the first rating.

A device for measuring eye movement in a human subject comprises a housing, at least one stimulator mounted to the housing, and a sensor. The at least one stimulator is configured to provide stimulus to one or both eyes of the subject. The sensor is configured to collect information related to movement of one or both eyes of the subject. The device also includes a user interface that is configured to control the at least one stimulator and display information collected by the camera.

According to one embodiment, an eye movement detecting device comprises first, second, third, fourth and fifth electrodes. A line connecting the first and the third electrodes passes through the right eye and a line connecting the second and the fourth electrodes passes through the left eye on at least one of a front view, a plan view or a side view. A distance between the fifth and the first electrodes is equal to a distance between the fifth and the second electrodes.

A distance between the fifth and the third electrodes is equal to a distance between the fifth and the fourth electrodes. The detector respectively detects a horizontal movement of the right eye and a horizontal movement of the left eye.
