Problem Statement Design a computer interface Valve control/liquid exchange Integrate light wheel Data storage

The Lab

Design Constraints Design an interface in Lab. VIEW to Control & record light intensity Integrate solution delivery Real-time analysis Export data Adjust sample duration & number

The current interface The interface Displays graphs in real-time Lacks some functionalities The GUI Looks cluttered Unappealing colors User enters input via keyboard

Design 1: Tweak existing interface Keep existing Lab. VIEW template Add necessary functionality to back end Slightly modify GUI More visually pleasing Better organization

Design 2: GUI Overhaul Simplicity Consistency Familiarity

Design 3: Start from scratch Scrap existing design Choose programming Language Focus on modularity

Decision Matrix Criteria (weight) Tweak Overhaul Start over Functionality (30) 30 30 30 Ease of Use (30) 10 30 30 Complexity (20) 20 10 0 Aesthetic Appeal (15) 5 15 15 Modularity (5) 2 2 5 Total (100) 67 87 80
