Abstract: A first mobile device receives actuation of a victim assistance button of an emergency assistance application associated with a first identifier of a first emergency profile associated with a first user of the first mobile device. The first mobile device receives, from a second mobile device, using a short-range communication interface, a second identifier of a second emergency profile associated with a second user of the second mobile device, the second identifier being encrypted and decryptable using a common decryption key associated with the emergency assistance application. The first mobile device decrypts the second identifier using the common decryption key, and provides, to an emergency service provider server, using a long-range communication interface, the second identifier that enables the emergency service provider server to retrieve the second emergency profile from a data storage module of an emergency information system at which the first and second emergency profiles are registered.

Abstract: According to an example aspect of the present invention, there is provided an eye tracking apparatus comprising an illumination device comprising at least one light source, configured to illuminate a user's eye when the user is using the eye tracking apparatus, at least one detector configured to obtain information on the user's eye when the user is using the eye tracking apparatus, and at least one processing core configured to determine a direction of the user's gaze based on the information on the user's eye and based on an indication of place and/or orientation of the illumination device with respect to the at least one detector.

Abstract: According to an example aspect of the present invention, there is provided an apparatus comprising at least one processing core, at least one memory including computer program code, the at least one memory and the computer program code being configured to, with the at least one processing core, cause the apparatus at least to determine a reference point in a three-dimensional space based at least in part on locations of first and second features of a user's eye and on the user's gaze distance, and perform a mapping of the reference point into a viewed scene of a near-to-eye optical device to obtain an estimated gaze point and/or gaze direction of the user who is using the near-to-eye optical device, the mapping being based at least in part on calibration information associated with the user.

Abstract: Methods and systems for identifying watchers of an object of interest at an incident scene. One method includes receiving, with an electronic processor, an object identifier corresponding to the object of interest. The method includes determining a watcher status for the object of interest. The method includes generating a notification based on the watcher status and the object identifier. The method includes transmitting, with a communication interface communicatively coupled to the electronic processor, the notification to an available watcher at the incident scene.

Abstract: According to an example aspect of the present invention, there is provided a near-eye ocular device, the near-eye ocular device comprising an ocular pathway enclosed by an enclosure, comprising at least one light emitter, configured to illuminate an eye of a user to produce corneal glints on the eye when the user is using the near-eye ocular device, and at least one sensor configured to obtain an image of the eye of the user when the user is using the near-eye ocular device.

Abstract: A method and apparatus for determining gaze direction information, includes a light source for forming illuminating light to an eye region of a user, and optical element(s) configured to guide the illuminating light from the light source to the eye region. The illuminating light is dynamically adjustable to generate a dynamic light beam on the eye region, and a sensor is configured to capture reflected light on the eye region and generate reflection eye data. The apparatus can maintain user profile information, adjust spectral power distribution of the light source based on the user profile information, receive the reflection eye data, and generate the gaze direction information based on the reflection eye data.
