         20 . The pedestrian warning device of  claim 1 , wherein the computing device is a mobile telephone. 
     
     
         21 . The pedestrian warning device of  claim 1 , wherein the computing device is a wearable device. 
     
     
         22 . The pedestrian warning device of  claim 1 , further comprising a GPS configured to identify a location of the pedestrian. 
     
     
         23 . The pedestrian warning device of  claim 22 , wherein the GPS is configured to identify whether the pedestrian is crossing a street at an intersection. 
     
     
         24 . The pedestrian warning device of  claim 22 , wherein the pedestrian warning device is configured to monitor the gaze of the pedestrian, and the alarm is configured to warn the pedestrian in response to an attempt to cross a street without looking in a direction of oncoming traffic. 
     
     
         25 .
