First Claim
Patent Images
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.

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.

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. - View Dependent Claims (14, 15, 16, 17)

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.
