As a college student studying interaction design, it feels important to study Ada Lovelace and Lillian Gilbreth because they show how early ideas shaped the way we approach technology and design today.Ada Lovelace, known as the first computer programmer, didn’t just write code, she thought about how to make machines more than just number crunchers. Her work on Charles Babbage’s analyzing machine showed that machines could process data and symbols creatively, almost mimicking the way humans think. In a world where we are constantly interacting with technology, her vision reminds us that our designs today have the potential to shape the future.

Also，on the other side， Lillian Gilbreth introduces a human-centered approach to her work in ergonomics and psychology. She focuses on making everyday tasks easier and more efficient by understanding how people interact with their environment (whether in a factory or at home). For someone like me, learning to design easy-to-use interfaces and improve people’s lives feels directly relevant to her work.Gilbreth’s emphasis on human needs reminds us that good design is not just about aesthetics or functionality-it’s about understanding people and designing systems for them. These women’s contributions help us see how long-held ideas about people and technology influence the decisions we make in IXD today.
