Making Change by Changing the Callascope

A 2019 interview with Mercy Asiedu on the development of the Callascope

Tell me about the new Callascope! What updates or changes were made and why?

The main update involves switching from using a 2 megapixel camera to using a 5 megapixel camera, because the 2 megapixel camera’s image quality wasn’t sufficient for the level of clarity and resolution that we needed while imaging the cervix. Initially, we weren’t using the 5 megapixel camera because of sizing issues (it’s much larger), so when we switched we had to change some of the design, which brings me to change number two.

The callascope and images

How did the principals of human-centered design play a role in the development of the device?

Human-centered design was employed much more obviously in the beginning and it hasn’t really changed since then. When we were making the original design, we worked with potential patients and providers. We provided them with a lot of prototypes, and they gave us feedback about what was most comfortable, what would be easy to use, etc. We learned a lot about comfort and ease of use compared to the speculum.

This month we are talking about how to be a changemaker using our WISH model for health care. Can you explain how the device fits within the context of the WISH model, as well as the changes in health care that you would hope to see?

The WISH model has three main arms: women-inspired technology, community workforce training, and peer-to-peer learning. The Callascope fits in with all three of these arms.
