Disha-Interactive Device For Traffic Police
Disha is a wearable, computing design for traffic police in India, which addresses problems related to signaling and communication. In India, there are unique traffic problems because of the number of pedestrians on the road, improper town planning and road transport.
Design of the interface
The interface elements are designed for a capacitive touch screen on the wearable device. Traffic policemen can use this interface to control Signal, Traffic and tasks related with Law enforcement.Traffic policemen use walkie-talkie to get information about traffic conditions. They have to pick the information relevant to their zone out of the information broadcasted for all the zones in the city. This interface lets him select the information relevant to a particular zone.
Consider a scenario where the policeman wants to over-ride a signal named 'Gandhi Chowk'.
Step 1: He selects the signal by touching the signal and pressing 'Select' button.

Very often, traffic policemen override the preset signaling system on smaller roads to control the traffic. LED hand-signaling unit facilitates hand-signaling and improves visibility at night.
