Product: User interface
Respinor has been developing a sensor using an ultrasound transducer for monitoring the diaphragm excursion and respiratory rate. This technology is to be used in the first target application for patients in the ICU under mechanical ventilation during the process when the breathing tube is removed, the weaning process.
K8 has helped Respinor in the first place with a quick, realistic concept mock-up and visuals to explain the product and the use to possible investors. With the help of the design driven innovation support (DIP), the project looked further into the use of the whole system for the patient and the medical helpers in the ICU. The outcome of the DIP finding is developed further into the sensor and control unit where we also proposed a UX-design (user experience design). By designing both the physical products and the UX and UI for the control unit, we were able to secure a consistent user-friendliness throughout the product.
For the UX/UI development we looked at Respinors existing user interface and mapped out its obvious painpoints relating to user friendliness and UX conventions. This, together with input from the Respinor team, gave us a starting point and enabled us to come up with some quick conceptual sketches for a future user interface. These sketches were presented to the Respinor team and further developed and finally prototyped in high fidelity in proto.io.
Being a medical device, it was important to give the right information at the right time. This steered the process to focus on user expectations and needs and to create a hierarchy in which the most critical data was in focus. We also looked at the aspect ratio of the graphs where it was important to not visualize the data in an inaccurate way.
The final solution is a user interface which enables the user to easily navigate between live feed data, trends and in-depth statistics. By using well known conventions within UX design the interface clearly communicates what elements are static, and which are interactive. By toning down the colors we also made the interface more comfortable to use, seeing that the hard contrast between a black background and a with typeface can be tiering on the eyes. By running a process from low fidelity sketches to a high-fidelity prototype we were able to quickly iterate and meet the needs and wishes of the users and the team at Respinor.
