Yanliang Sun, and my colleagues at SR Research Ltd. This book is a useful reference for eye-tracking researchers, but you can also use it in graduate or undergraduate level programming courses. The example scripts accompanying this book are freely available on GitHub. For eye-tracking, this book will cover the Pylink library in detail. Some methods require a specific interface, a target being connected, or an emulator being connected, and will raise errors as. This interface is provided through the JLink class, which provides several of the functions provided by the native SDK. This book will first introduce the building blocks and syntax of Python, then discuss libraries that we can use to program psychology experiments, i.e., PsychoPy and Pygame. The PyLink package provides a Pythonic interface for interacting with the J-Link C SDK. This high-speed eye-tracker has unmatched precision and accuracy, and it has been used in well over 9000 peer-reviewed publications. EyeLink eye-trackers are arguably the best research-grade tracker available on the market.
#Install psychopy with pylink series#
The eye-trackers featured in this book are the EyeLink series trackers manufactured by SR Research Ltd. The eye-trackers used in the lab are typically faster, more accurate, and of course, more expensive than the ones seen in consumer goods (e.g., VR goggles) or usability labs. What sets this book apart is its focus on eye-tracking.Įye-tracking is a widely used research technique in psychology and neuroscience labs. There are quite a few Python books on the market featuring programming tools designed for psychologists (e.g., PsychoPy). The content of this book is based mainly on my research experience and the courses I have taught previously. I experimented with different programming languages and tools but finally settled down with Python for its easy syntax, flexibility, versatility, and open community. PyGaze acts as a wrapper around several existing packages, among which PyGame, PsychoPy, pylink (for SR Research EyeLink systems), SensoMotoric Instruments’ iViewX API, and the Tobii SDK.
I had little knowledge of computer programming when I started my graduate study about 16 years ago. Its application in psychology has expanded from scripting computer-based experimental tasks to all aspects of research, including but not limited to data collection, analysis, and visualization. Python is becoming more and more popular among scientists.
