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 the traffic signal;
determining, by the computing device, an attention focus area of the 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 a background color the same as a color of a light illuminated at the traffic 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 , further comprising receiving a status signal from a traffic signal system associated with the traffic signal.

9. The method of claim 8 , further comprising comparing global positioning system (GPS) coordinates of the vehicle to GPS coordinates included in the status signal.

10. The method of claim 8 , wherein:
the computing device causes the determined target display device to display the background color as red based on a red light illuminated being at the traffic signal;
the computing device causes the determined target display device to display the background color as yellow based on a yellow light illuminated being at the traffic signal; and
the computing device causes the determined target display device to display the background color as green based on a green light illuminated being at the traffic signal.

11. The method of claim 8 , wherein the computing device causes the determined target display device to change the background color from red to green based on the traffic signal changing from a red light to a green light.

12. The method of claim 1 , wherein the attention focus area of the driver of the vehicle is determined based on data from at least one sensor.

13. 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 the traffic signal;
determining, by the computing device, an attention focus area of the driver of the vehicle;
determining, by the computing device, a target display device based on the determined attention focus area;
receiving, by the computing device, a status signal from a traffic signal system associated with the traffic signal;
comparing coordinates of the vehicle to coordinates included in the status signal; and
causing, by the computing device and based on the received status signal, the determined target display device to display a traffic signal icon that displays a color that is the same as a color of a light illuminated at the traffic signal.

14. The method of claim 13 , wherein the computing device causes the determined target display device to change the color displayed by the traffic signal icon from red to green based on the traffic signal changing from a red light to a green light.

15. The method of claim 13 , wherein the determining the attention focus area comprises analyzing at least one direct indicator from the group consisting 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 method of claim 13 , wherein the determining the attention focus area comprises analyzing at least one indirect indicator from the group consisting 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.

17. The method of claim 13 , wherein the attention focus area of the driver of the vehicle is determined based on data from at least one sensor.

18. 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 the traffic signal;
determining, by the computing device, an attention focus area of the driver of the vehicle;
determining, by the computing device, a target display device based on the determined attention focus area;
receiving, by the computing device, a status signal from a traffic signal system associated with the traffic signal; and
causing, by the computing device and based on the received status signal, the determined target display device to display directional icons having colors that correspond to colors of lights of the traffic signal.

19. The method of claim 18 , wherein the directional icons are selected from the group consisting of a red arrow, a yellow arrow, and a green arrow.

20. The method of claim 18 , wherein the computing device causes the determined target display device to change the displayed directional icons based on changes in the status signal received from the traffic signal system.
