Abstract

Systems and methods for alerting a driver to a status of a traffic signal are disclosed. A computer-implemented method includes: detecting, by a computing device, that a vehicle is stopped at an intersection with a traffic signal; determining, by the computing device, an attention focus area of a driver of the vehicle; determining, by the computing device, a target display device based on the determined attention focus area; and causing, by the computing device, the determined target display device to display information to alert the driver of a status of the traffic signal.

First claim

What is claimed is:

1. A computer-implemented method for alerting a driver to a status of a traffic signal, comprising:
detecting, by a computing device, that a vehicle is stopped at an intersection with a traffic signal;
determining, by the computing device, an attention focus area of a driver of the vehicle based on data from at least one sensor;
determining, by the computing device, a target display device based on the determined attention focus area;
causing, by the computing device, the determined target display device to display information to alert the driver of a status of the traffic signal,
further comprising receiving a status signal from a traffic signal system associated with the traffic signal; and
comparing global positioning system (GPS) coordinates of the vehicle to GPS coordinates included in the status signal.

2. The method of claim 1 , wherein the determining the attention focus area comprises analyzing at least one of direct indicators and indirect indicators.

3. The method of claim 2 , wherein the direct indicators comprise at least one of:
a determined gaze location of the driver;
a determined position of a face of the driver;
a determined location of hands of the driver; and
a determined weight of the driver.

4. The method of claim 2 , wherein the indirect indicators comprise at least one of:
detecting usage of an input device;
detecting that a screen is turned on;
detecting keystrokes that indicate user action;
detecting messages sent, received or viewed;
detecting applications launched;
detecting user interaction with applications;
detecting a telephone call in progress; and
detecting movement of an accelerometer.

5. The method of claim 1 , wherein the target display device is a fixed electronic display that is part of the vehicle.

6. The method of claim 1 , wherein the target display device is a temporary display device.

7. The method of claim 6 , further the computing device pairing with the temporary display device.

8. The method of claim 1 , wherein the displayed information indicates the status of the traffic signal.

9. The method of claim 8 , wherein the displayed information comprises one of:
a background color the same as a color of a light illuminated at the traffic signal;
an icon showing the color of the light illuminated at the traffic signal;
arrows indicating direction status of the traffic signal; and
a timer indicating a countdown time until the traffic signal changes.

10. The method of claim 9 , further comprising changing the displayed information based on a changed status of the traffic signal.

11. The method of claim 1 , wherein a service provider at least one of creates, maintains, deploys and supports the computing device.

12. The method of claim 1 , wherein steps of claim 1 are provided by a service provider on a subscription, advertising, and/or fee basis.

13. A computer program product for alerting a driver to a status of a traffic signal, the computer program product comprising a computer readable storage medium having program instructions embodied therewith, the program instructions executable by a computing device in a vehicle to cause the computing device to:
receive GPS coordinates of a traffic signal via wireless communication from a traffic signal system;
detect that the vehicle is stopped at an intersection with the traffic signal based on the computing device comparing an unchanging GPS location of the vehicle to the received GPS coordinates of the traffic signal;
determine an attention focus area of a driver of the vehicle by analyzing direct indicators and indirect indicators, wherein the direct indicators are based on data from at least one sensor;
determine a target display device based on the determined attention focus area;
cause the determined target display device to display information to alert the driver of a status of the traffic signal; and
cause the determined target display device to change the displayed information based on a changed status of the traffic signal.

14. The computer program product of claim 13 , wherein the target display device is one of: a mobile device, and a fixed electronic display that is part of the vehicle.

15. The computer program product of claim 13 , wherein the direct indicators comprise at least one of:
a determined gaze location of the driver;
a determined position of a face of the driver;
a determined location of hands of the driver; and
a determined weight of the driver.

16. The computer program product of claim 13 , wherein the computer device in the vehicle is paired to a temporary display device also in the vehicle, the computer device receives data defining the indirect indicators from the temporary display device, and the data defining the indirect indicators indicating at least one of:
detection, by the temporary display device, that a screen is turned on;
detection, by the temporary display device, keystrokes that indicate user action;
detection, by the temporary display device, messages sent, received or viewed;
detection, by the temporary display device, applications launched; and
detection, by the temporary display device, user interaction with applications.

17. The computer program product of claim 13 , wherein the displayed information comprises one of:
a background color the same as a color of a light illuminated at the traffic signal;
an icon showing the color of the light illuminated at the traffic signal;
arrows indicating direction status of the traffic signal; and
a timer indicating a countdown time until the traffic signal changes.

18. A system for alerting a driver to a status of a traffic signal, comprising:
a CPU, a computer readable memory and a computer readable storage medium associated with a computing device;
program instructions to detect that a vehicle is stopped at an intersection with a traffic signal;
program instructions to determine an attention focus area of a driver of the vehicle by analyzing at least one of direct indicators and indirect indicators, wherein the direct indicators are based on data from at least one sensor;
program instructions to determine a target display device based on the determined attention focus area;
program instructions to cause the determined target display device to display a counter indicating a countdown time until the traffic signal changes; and
program instructions to cause the screen of the determined target display device to go blank when the counter reaches zero,
wherein the program instructions are stored on the computer readable storage medium for execution by the CPU via the computer readable memory;
the target display device is one of: a mobile device, and a fixed electronic display that is part of the vehicle;
the computing device is comprised in the vehicle and receives GPS coordinates of the traffic signal via wireless communication from a traffic signal system; and
the detecting that the vehicle is stopped at the intersection with the traffic signal comprises the computing device in the vehicle comparing an unchanging GPS location of the vehicle to the received GPS coordinates of the traffic signal.

19. The method of claim 1 , wherein:
the computing device is comprised in the vehicle;
the computing device in the vehicle receives the status signal from a traffic signal system associated with the traffic signal via wireless communication;
