At circadian lighting company Chroma Viso I helped develop internal tools and customer facing user interfaces. I prototyped for web and mobile while planning and conducting a wide range of user centric studies.
We developed a large range of digital tools. Most of the work is under NDA. Following is a couple of screengrabs I am allowed to show.
This video shows the flow of the web application for controlling circadian light at carehomes. The test subject is a healthcare worker. All the dialog is in Danish. In short, the test subject explains any thoughts she has about the design and speaks out loud about things she likes/dislikes.
