Abstract

A display exposure monitoring module configured to monitor the exposure of a person to at least a display, the module including a communication component configured to receive display exposure data indicative of the exposure of the person to a display, a memory storing computer executable instructions and configured to store the received display exposure data; and a processor for executing the computer executable instructions, wherein the computer executable instructions includes instructions for processing the display exposure data to generate display exposure information indicative of an alert information and/or a visual behavior recommendation and/or an activation parameter.

Claims

1. A display exposure monitoring module configured to monitor exposure of a person to a plurality of displays of different devices, the module comprising:

a communication component configured to receive display exposure data indicative of the exposure of the person to the plurality of displays, the display exposure data comprising time exposure data indicative of a time of exposure of the person to the plurality of displays, the time exposure data comprising a daily time of exposure of the person to different categories of display devices,

a memory storing computer executable instructions and configured to store the received display exposure data; and

a processor for executing the computer executable instructions, wherein the computer executable instructions comprises instructions for processing the display exposure data to generate display exposure information indicative of an alert information and/or a visual behavior recommendation and/or an activation parameter.

2. The display exposure monitoring module according to claim 1, wherein the display exposure data comprise electromagnetic wave data indicative of a feature of electromagnetic waves received by eyes of the person when using the plurality of displays.

3. The display exposure monitoring module according to claim 1, wherein the communication component is further configured to receive visual fatigue data indicative of visual fatigue of the person and the instructions for processing the display exposure are arranged to generate display exposure information considering the received visual fatigue data.

4. The display exposure monitoring module according to claim 1, wherein the communication component is further configured to communicate at least part of the display exposure information to the plurality of displays.

5. A display exposure determining device comprising at least one display exposure sensor configured to sense at least one display exposure parameter indicative of the exposure of the person to a plurality of displays when using the display exposure determining device and a communication unit configured to communicate display exposure data indicative of the exposure of the person to the display exposure monitoring module according to claim 1.

6. The display exposure determining device according to claim 5, wherein the display exposure sensor comprises a scene image acquisition sensor, a camera, configured to acquire a scene image of an environment facing the person and an image processing module configured to process the acquired images to identify an active display in the environment facing the person.

7. The display exposure determining device according to claim 5, wherein the display exposure monitoring module is embedded in the device.

8. The display exposure determining device according to claim 5, wherein the display exposure determining device is one of the devices comprised in the list consisting of a head mounted device, a smartphone and a tablet.

9. A display exposure monitoring system comprising a display exposure monitoring module according to claim 1, and a display exposure determining device, wherein the display exposure determining device is configured to send display exposure data to the display exposure monitoring module.

10. The display exposure monitoring system according to claim 9, further comprising an output unit arranged to output a signal, a visual and/or audio signal, to the person based on the information indicative of a visual recommendation for the person.

11. The display exposure monitoring system according to claim 9, further comprising a programmable lens device comprising a programmable lens and an optical function controller, programmable lens having an optical function and extending between at least one eye of a wearer and a real world scene when the device is used by the wearer, and the optical function controller being arranged to control the optical function of the programmable lens, wherein the optical function controller is arranged to receive display exposure information from the display exposure monitoring module and modify the optical function of the programmable lens device based on the received display exposure information.

12. A method for determining display exposure information related to exposure of a person to a plurality of displays of different devices, the method comprising:

display exposure data receiving step, during which display exposure data indicative of the exposure of the person to the plurality of displays are received, the display exposure data comprise time exposure data indicative of a time of exposure of the person to the plurality of displays, the time exposure data comprising a daily time of exposure of the person to different categories of display devices, and

display exposure information determining step, during which a display exposure information indicative of an alert information and/or a visual behavior recommendation and/or an activation parameter is determined based on the display exposure data.

13. The method according to claim 12, wherein the display exposure data are determined based on an analysis of images of a scene facing a user.

14. The method according to claim 12, wherein the display exposure data comprise electromagnetic wave data indicative of a feature of electromagnetic waves received by the person when using the plurality of displays.
