Designing mobile based computational support for low-literate community health workers

This study was conducted in tribal area of Bastar district of Chhattissgarh, India. To understand mobile usability, 97 low-literate and novice users were selected and for testing of UI design 18 subjects for first activity and 24 subjects for second activity were selected from the same area. Our initial results show that the task completion with both the activities was high with very few errors. With pre-recorded voice instructions in various languages, the same application platform with color-coded graphical UI can be used effectively in countries like India where many regional languages are there. And digital signature interface can provide authentication mechanism and reduce issues related to fake data entries by community health workers (CHWs).
