Text-Free User Interfaces

Design recommendations for computer-human interfaces that would allow a first-time, non-literate person, on first contact with a PC or a mobile phone, to immediately realize useful interaction with minimal or no external assistance. Follows an ethnographic design and iterative prototyping process and rigorous user evaluations, involving more than 700 hours spent in the field and 570 study participants from low-income, low-literate communities across India, Philippines and South Africa.
