Handsfree interactions, value add through information delivered at the right time, and offline capability.

Through interviews with Tristel’s team we learned that their clients were often recording infection control events in areas with poor connectivity, whether that be a refugee camp in Turkey or a hospital in Manchester, but would want to access data from administrative offices in different buildings or even countries. In addition they would often lack access to hardware.

Our solution was to develop a native mobile application for recording infection control events and a web application for accessing the data. The app would be provided on a device with a housing, so that clients need not use their own hardware and we could reduce costs by optimising for one specific Android device for the MVP.

After creating low-fidelity prototypes we conducted usability testing in an ultrasound clinic to identify design issues at an early stage. One of the most interesting findings was that when using paper forms, the clinic staff had to wash their hands twice, once after completing device cleaning with Tristel products and again after recording the event. We also learned that with one specific Tristel product that required 3 specific steps to effectively use, there was an opportunity to reduce the risk of misuse.

Following feedback we added features to record infection control evens with both voice and gesture interfaces, thus eliminating the need for double washing of hands, and video training for how to use the products to mitigate the risk of misuse.
