Self-checkout Kiosk at Grocery Stores
Self-checkout kiosk (SCK) lanes at grocery stores and retail stores are one of similar services we often see today, called Self-Service Technologies (SST). Sometimes we don
For any type of medical devices, safety, accuracy, and efficiency are always top priorities. The interface design is about helping medical professionals save time and prevent errors.
There are basically two types of infusion pumps in the medical field, stand-alone and smart infusion pump. For stand-alone type, the errors are usually caused by wrongly rendering results and inappropriate designed interfaces. “Web of things” technology connects the infusion devices and makes them smarter and also adds the complexity to the interface design. The errors for the smart infusion devices are also from lack of communication between members in the community and from inappropriate decision support system.

It is true that usability practitioners are still facing many challenges everyday. Many studies found that different teams tested same tasks, but the difference in finding between teams was significant. On Rolf Molich and Joseph Dumas (2006)’s study, the average percentage overlap was only 11.5%. The limited overlap could be interpreted as a sign of poor evaluation, or you can think that the usability space is so huge that it is inevitably leads to limited overlap.
For the people who are new to this field, it seems the usability evaluations are not reliable at all. While, I think with carefully preparing and planning, the improvement could be significant. I believe there are three major aspects that need to be considered:
1. Improving Evaluators and Moderators’ Effect
The quality of the evaluators or moderators would have major impact on the evaluation result. Improving heuristics expert review and providing suitable heuristics list could let practitioners
It is all new experience for me to conduct the product user testing. I was usually designing the user interfaces at back end and rarely contacted with the actual users.
