Product: User interface
Respinor has developed an ultrasonic based sensor for monitoring the diaphragm excursion and respiratory rate of patients in intensive care. This technology is used to monitor patients under mechanical ventilation and during the weaning process when the breathing tube is removed.
K8 has worked with Respinor in the startup phases with quick, realistic concept demonstrations and visuals to explain to possible investors. With the help of the Design-driven Innovation Program (DIP), the project looked further into the user experience of the whole system for the patient and medical clinicians in the Intensive Care Unit (ICU). The outcome of the DIP findings were developed further into the Ultrasonic Probe and Read Out Unit; here we also proposed a user experience and interaction (UX/UI) design. By designing both the physical products and the UX/UI for the Read Out Unit, we were able to secure a consistent user experience and satisfaction throughout the product.
For the UX/UI development we looked at Respinor’s existing user interface and mapped out its obvious pain-points relating to usability and UX conventions. Being a medical device, it was important to display 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 such that the display of data could not be misconstrued. This, together with input from the Respinor team, enabled us to deliver conceptual sketches a touch screen based user interface.
These sketches were presented to the Respinor team and further developed and finally prototyped in high fidelity using proto.io.
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 colour contrast we also made the interface more comfortable to use, being less tiring 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 both the users and team at Respinor.
