Sometime after the earthquake in Nepal I found at the UNDP website these animations: - Basic Tips for Safe Demolition and Debris Removal: https://www.youtube.com/watch?v=VNF6p_nC28c - Basic tips for Earthquake Safe Building Construction: https://www.youtube.com/watch?v=KirIA7gAwt8 And also a link to a series of videos: - Earthquake Safe Building Practices in Nepal: Video Toolkit: https://www.youtube.com/watch?v=2NiNjxBtRHM The videos where intended to be shown to the local people. It has some similarities with your idea. I thought it was a smart way to communicate "technical issues" without text.
Thanks for your comment. We do not know a previous pilot to improve literacy, but we know that people use similar apps to successfully learn foreign languages. There are two ways to go ahead: 1) Promote the app in target communities, so that people will install it in the telephone they already have and use it. In this scenario, encouraging to use the app is critical (yet to be designed). 2) Subsidize or give away cheap (10$-30$) mobile phones and factory-set them to always present the challenge after unlocking. This way the user gets a free/cheap telephone, and has to always use the app, because it cannot be disabled.
