First 5 minutes crucial -> brain damage

Goal -> reduce deathsCan we use current technology for reducing the response time?

Introduce VNS

Lay-men will be notified in a cardiac arrest situation

iOS application

Some news paper articles

Some newspaper articles

Some newspaper articles

Other projects Many other projects out there

PulsePoint, Hartveilig wonen, HartslagNu, …

Most of them:

SMS service and based on profiles.

Distance between volunteer measured with radius

My work Analysing other projects and legal aspects

Requirements

Paper prototype + evaluation

Digital prototype + evaluation

Database + queries

Web service (JSON)

Push notification server

What has yet to be done? Linking client with web service

Logging in Pushing GPS location Notifying has arrived at the scene

Client handling of push notifications Evaluation

Digital prototype evaluation Focus on usability not visually appealing

7 people ages 23 – 55, no computer scientists!

Down side not much feedback in terms of design

Using System Usability Scale

Feedback overall positive
