# Development of an Ergonomic User Interface Design of Calcium Imaging Processing System
## 5 Discussion  
The present study developed an ergonomic UI design for a new O-BMI system that users can use efficiently and conveniently, based on the needs identified through user research. Researchers in neuroscience developed middleware platforms for the visualization and management of brain activity measurements. For example, [PERSON] et al. (2018) developed an open-source middleware platform that can be used to build an application
