Gender has been a part of HCI both implicitly and explicitly since its inception, affecting the everyday practice of designers and developers and the technologies they create. This has occurred as disparate numbers of men and women are involved in computing fields and designers often follow the "I-methodology," as well as relying on gender stereotypes and focusing on gender difference. This chapter outlines various strategies and approaches to addressing gender in nuanced ways in HCI, towards creating gender-aware and gender-inclusive technologies and practices. These include understanding gender, feminist theories, and queer theories; analyzing gender scripts and metaphors embedded in technologies; reflexivity regarding developers' and designers' norms and values; feminist design and an intersectional approach; and designing for future diversity.
