NENA/APCO Human Machine Interface & PSAP Display Requirements

Standard number: 

54-750 v1

Document description: 

NENA and APCO have jointly developed this document for the purpose of prescribing requirements for the human machine interface (HMI) display for the Next Generation 9-1-1(?) (NG9-1-1(?)) System. The ubiquitous access to 9-1-1 emergency services needed in today’s world of evolving technology is driving the need to introduce a broader array of interconnected networks that would comprehensively support emergency services.

The HMI within the NG9-1-1(?) PSAPs will assist in consolidating and presenting emergency information received via IP, cellular, telematics, sensor, and public switched telephone network (PSTN) devices to the call taker in an efficient end-user format. It will provide call takers with an interface to manage access to 9-1-1 requests for services received through virtually any communications device, provide a more direct ability to share critical data with emergency services responders providers from any location, transfer emergency calls to another PSAP, and forward the location and other critical data with the call. The HMI should be designed and configured in such a manner as to maximize a call taker’s ability to efficiently manage a call.

The HMI design and configuration will include consideration as to the number of monitors, number of applications presented at once, the amount of information displayed at once, and the need to move call taker focus from one monitor/application in order to take action via key board, mouse, key pad, touch screen, and other similar devices.
