Paper forms are widely used for data collection in low-resource settings
![Page 38: HCI$and$Design - nixdell.comToday Computing*and*the*developing*world Overview Version*1.0 Version*2.0 Some*of*Nicki’s*projects](https://reader035.fdocuments.in/reader035/viewer/2022081405/5f09bcd77e708231d4284770/html5/thumbnails/38.jpg)

Form design and approval
Field workers fill out forms
Manual data entry
Aggregation and analysis
Manual data entry is time consuming and error prone
Data entry is a huge bottleneck for many organizations
![Page 40: HCI$and$Design - nixdell.comToday Computing*and*the*developing*world Overview Version*1.0 Version*2.0 Some*of*Nicki’s*projects](https://reader035.fdocuments.in/reader035/viewer/2022081405/5f09bcd77e708231d4284770/html5/thumbnails/40.jpg)
40
How can we improve paper-digital workflows in global development?
Key Idea Ease the data entry bottleneck by using a mobile device to automatically digitize paper-based data on the device
Challenges and ConstraintsHandle forms in very poor condition
Range of applications and data types
Robust performance
Perform computation locally
Usable by different stakeholders
