Challenges and Opportunities of Mobile Phone-Based Data Collection, Demombynes
Mobile data collection
Using smartphones or tablets for data collection (instead of paper forms)
Data storage
build collect aggregate results analyse - report
Advantages
Manage surveys across regions; Faster to fill + compile; Data more accurate:
● collect+digitize at source ● no more data entry ● data cleaning limited ● pre coded ranges,
restrictions, skip logic user friendly / motivating; easy monitoring of data
collection team
Costs
Hardware Training Collection form design Data transmission (recurring)
Data aggregation (hosting)
Management
Data types - what to collect
Geographic data GPS coordinates
Choice boxes Radio buttons
Multiple choice
Multimedia data Videos
Audio
Pictures
Sensors Signatures
Barcodes
Electronic sensors
Manual entry Text
Numbers
Time - date Time

In CDI
ISSD – with KIT Genevieve
Cascape ? SBN ? IFAD evaluation
Many possible tools
Magpi (episurveyor) Formhub Mobenzi researcher Commcare m-farm Do forms AKVO flow Text to change
CSPro mOpenMRS Epicollect FrontlineSMS RapidSMS Ushahidi
ODK – Open Data Kit
Considerations in selecting tool - provider
Survey question types Control + management
(self or pay service provider)
Data security Time-frame Costs (set-up / service)
Customizability (by whom)
Tools already used (partner)
Things to keep in mind before deployment
How ‘fast’ do you need the data? Real time, daily, ... Network availability / affordability Materials
● Smartphone – tablet?
● Screensize?
● Operating System (Android, iOS, windows mobile)
● Extra spare devices
● Settings + installing device
● Battery pack
Planning 1. Ongoing activities
2. One-time activity

ODK - open data kit version 1.x
Open Source + free, used by many (10s of thousands) Basis for many other apps (Enketo, Magpi, Kobo toolbox)

ODK collect
ODK aggregate
hosts data + provides extraction interfaces
