Abstract

An approach is provided for linking the navigation and flashlight functions of a mobile device for guidance purposes. A coordination platform determines mapping information, navigation information, or a combination thereof associated with at least one device. The coordination platform determines at least one operational parameter for at least one flashlight component of the at least one device based, at least in part, on the mapping information, the navigation information, or a combination thereof. The coordination platform causes, at least in part, a configuration of the at least one flashlight component based, at least in part, on the at least one operational parameter.

First claim

What is claimed is:

1. A method comprising facilitating a processing of and/or processing (1) data and/or (2) information and/or (3) at least one signal, the (1) data and/or (2) information and/or (3) at least one signal based, at least in part, on the following:
at least one determination of mapping information, navigation information, or a combination thereof associated with at least one device;
at least one change of at least one operational parameter for at least one flashlight component of the at least one device based, at least in part, on the mapping information, the navigation information, or a combination thereof, to include a directional feedback in at least one real-world light that is projected by the at least one flashlight component and aims towards a current travel route of the at least one device in a dark real-world environment; and
a configuration of the at least one flashlight component based, at least in part, on the at least one change of the at least one operational parameter.

2. A method of claim 1 , wherein the directional feedback indicates whether the current travel route aims towards a real-world travel destination associated with the at least one device, and the (1) data and/or (2) information and/or (3) at least one signal are further based, at least in part, on the following:
at least one determination of one or more routes, one or more guidance instructions, one or more destinations, one or more features, or a combination thereof associated with the mapping information, the navigation information, or a combination thereof, wherein the one or more routes include the current route;
the at least one change includes shifting a direction of the at least one light, and
at least one change of the at least one operational parameter based, at least in part, on whether the one or more routes, the one or more guidance instructions, the one or more destinations, the one or more features, or a combination thereof is in a field of view of the at least one device.

3. A method of claim 2 , wherein the (1) data and/or (2) information and/or (3) at least one signal are further based, at least in part, on the following:
a processing of sensor information associated with the at least one device to determine the field of view,
wherein the at least one change includes changing a color of the at least one light when the light aims away from the one or more routes, the one or more guidance instructions, the one or more destinations, or a combination thereof.

4. A method of claim 2 , wherein the at least one change further includes an increase or a decrease of the at least one operational parameter when the one or more routes, the one or more guidance instructions, the one or more destinations, the one or more features, or a combination thereof is in the field of view of the at least one device.

5. A method of claim 2 , wherein the at least one change further includes an activation of the at least one flashlight component when the one or more routes, the one or more guidance instructions, the one or more destinations, the one or more features, or a combination thereof is in the field of view of the at least one device.

6. A method of claim 2 , wherein the at least one change further includes a deactivation of the at least one flashlight component when the one or more routes, the one or more guidance instructions, the one or more destinations, the one or more features, or a combination thereof is not in the field of view of the at least one device.

7. A method of claim 2 , wherein the (1) data and/or (2) information and/or (3) at least one signal are further based, at least in part, on the following:
at least one determination of an input for specifying the one or more routes, the one or more guidance instructions, the one or more destinations, the one or more features, or a combination thereof.

8. A method of claim 2 , wherein the (1) data and/or (2) information and/or (3) at least one signal are further based, at least in part, on the following:
at least one determination of proximity information of the at least one device to the one or more routes, the one or more guidance instructions, the one or more destinations, the one or more features, or a combination thereof,
wherein the at least one operational parameter is based, at least in part, on the proximity information.

9. A method of claim 1 , wherein the at least one flashlight component includes, at least in part, an array of one or more lights, and wherein the at least one operational parameter is for operating at least a portion of the array.

10. A method of claim 1 , wherein the at least one operational parameter includes, at least in part, a light intensity parameter, a blinking frequency parameter, a light direction parameter, a light color parameter, or a combination thereof, and
the at least one change includes an increase or a decrease of the at least one operational parameter in proportion with an estimated time of arrival of the at least one device.

11. An apparatus comprising:
at least one processor; and
at least one memory including computer program code for one or more programs,
the at least one memory and the computer program code configured to, with the at least one processor, cause the apparatus to perform at least the following,
determine mapping information, navigation information, or a combination thereof associated with at least one device;
change at least one operational parameter for at least one flashlight component of the at least one device based, at least in part, on the mapping information, the navigation information, or a combination thereof, to include a directional feedback in at least one real-world light that is projected by the at least one flashlight component and aims towards a current travel route of the at least one device in a dark real-world environment; and
cause, at least in part, a configuration of the at least one flashlight component based, at least in part, on the at least one change of the at least one operational parameter.

12. An apparatus of claim 11 , wherein the directional feedback indicates whether the current travel route aims towards a real-world travel destination associated with the at least one device, and the apparatus is further caused to:
determine one or more routes, one or more guidance instructions, one or more destinations, one or more features, or a combination thereof associated with the mapping information, the navigation information, or a combination thereof; and
change the at least one operational parameter based, at least in part, on whether the one or more routes, the one or more guidance instructions, the one or more destinations, the one or more features, or a combination thereof is in a field of view of the at least one device.

13. An apparatus of claim 12 , wherein the apparatus is further caused to:
process and/or facilitate a processing of sensor information associated with the at least one device to determine the field of view.

14. An apparatus of claim 12 , wherein the at least one change further includes an increase or a decrease of the at least one operational parameter when the one or more routes, the one or more guidance instructions, the one or more destinations, the one or more features, or a combination thereof is in the field of view of the at least one device.

15. An apparatus of claim 12 , wherein the at least one change further includes an activation of the at least one flashlight component when the one or more routes, the one or more guidance instructions, the one or more destinations, the one or more features, or a combination thereof is in the
