Recently I stumbled upon this great video from IDE Wash about the creation of their “Easy Latrine 2.0” in Cambodia and how the new design of it was heavily influenced by human centered design. I particularly love how much the video focuses on the phases they went through during the HCD process.
It’s not terribly long and highly informative. Have a watch:
One of the most important aspects of our project has been the informed decisions we have made while engineering our sanitation system. Without the vital input we’ve received from our users, we would pour every resource we had into a sanitation solution that no one would ever use.
Through our on-site field testing, we’ve harvested data from the very people our toilet will help. It’s through that interaction and observation that we’ve been able to create a complete sanitation system that people will use and want to interact with on a daily basis.
