An iOS location-based emergency notification application

Michel Schevernels

Supervisor: Prof. Dr. Ir. Erik DuvalAdvisor: Gonzalo Parra

Context Sudden cardiac arrest Not the same as heart attack

Electrical vs Circulation problem First 5 minutes crucial -> brain damage Ambulances take up to 9 minutes to arrive

This in Germany

Goal Reduce deaths

Can we use current technology for reducing the response time? Introduce VNS

Lay-men will be notified in a cardiac arrest situation iOS application

Why a VNS? A study showed that an increase of 80% in the number of

ambulances only reduces the response time by a minute! Who is a volunteer?

Everyone who has a certificate of taking part in a CPR course.

Topical Issue – Article 17/10/2013

Literature Not much out there Studied other projects Very topical issue Legal aspects

PulsePoint Made in the USA Smartphones (Android and iOS) Only for public places Each community has to implement an interface

to communicate with their API App is free to download, but the community

has to pay an annual fee. Volunteers don’t have to be trained Offer: Notifications and AED locations

Hartveilig wonen Build in the Netherlands Texting service When notified, get a location of the victim and

an AED. Volunteers are notified based on their profile

settings Everyone can join, even those without

training, but you have to take a course. Offer: notification system, courses, counseling

and have a insurance policy

HartslagNu Build in the Netherlands Texting service In a SCA event 30 volunteers notified, 1/3 sent

to victim, 2/3 first to an AED Distance volunteers <-> victim 1000m,

volunteer <-> AED 500m Only volunteers with certificate can join Offers only notification system

The EMuRgency Project (Germany) Build by a team of the Aachen University Smartphone (Android) Everyone can join in, even those not trained Volunteers are notified based on pushed GPS

locations Distance volunteers <-> victim 1000m Don’t use AEDs Offer: Only notification system

SMSlivräddare (SMSlifesavers) Recent project from Sweden Only in Stockholm County Texting service Volunteers have to be trained Not finished

Legal Aspects Not legal as it stands Volunteers will have to have a certificate Volunteers are obliged to go help Are allowed to travel by car Data about a case and the participating

volunteers should be stored for 30 years

My work Analysing other projects and legal aspects Requirements Paper prototype + evaluation Digital prototype

Requirements iOS application Notification system guide volunteers to the

victim AED locations List of courses or info sessions in the vicitiny Information

Paper prototype

Evaluation prototype 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

Digital prototype Implementing in iOS (iOS7) Sat down with a Graphical Designer

He introduced an alternative home view. If there is time left, I will do an analysis which is

better. Almost finished Demo at the end.

Difficulties Push notification Program in the background Deciding who gets a notification Legal issues (Volunteers can’t accept a case,

store the information,…)

Planning December (31st)

Finishing digital prototype Look up requirements push server

January (8th): Evaluation digital prototype

January Studying

February Start programming

March Finish programming

Planning April
