xxii Foreword

The continuing discussions about which methods to use make this book a vital
resource for new students, active researchers, and serious practitioners. It provides a
comprehensive introduction with ample references for those who want more infor-
mation and for those who are ready to invent still newer research methods, tailored
to the issues they are studying.
This book also testifies to the vitality and ambition of HCI researchers, who have
moved from narrow studies about pointing times for different target sizes to broader
goals such as promoting information and communication technology for develop-
ment (ICT4D), ensuring universal usability, countering cyberbullying, and reducing
fake news. In a world where technology plays an increasing role, HCI is maturing
into a larger field that is becoming a necessary component of new ideas in business,
education, healthcare, community safety, energy sustainability, and environmental
protection. There is an astonishing history of success in enabling 8 billion people to
use novel technologies. This book celebrates that history and points to future direc-
tions that will yield new theories and still further benefits. There is also a great deal
of work to be done by the next generation of creative researchers.
