For my capstone project, I haven’t had to put the whole entire system together yet, but for two major parts we encountered a lot of problems while putting them together. The project consists of mainly a hardware part and a software part and within the hardware component we needed to integrate a camera with infrared to use the whole system for eye tracking. Although it doesn’t sound much of a problem, but when considering infrared safety guidelines and location in terms of the camera to the subject’s eyes and all, a lot of integration details came out to be problems. It delays the entire project timeline and dealing with them can be very hectic. Paying a lot of attention to the details in the planning process makes the integration a very smooth process.
