We make 3-5 eye movements per second, and these movements are crucial in helping us deal with the vast amounts of information we encounter in our everyday lives. In recent years, thanks to the development of eye tracking technology, there has been a growing interest in monitoring and measuring these movements, with a view to understanding how we attend to and process the visual information we encounter Eye tracking as a research tool is now more accessible than ever, and is growing in popularity amongst researchers from a whole host of different disciplines. Usability analysts, sports scientists, cognitive psychologists, reading researchers, psycholinguists, neurophysiologists, electrical engineers, and others, all have a vested interest in eye tracking for different reasons. The ability to record eye-movements has helped advance our science and led to technological innovations. However, the growth of eye tracking in recent years has also presented a variety of challenges - in particular the issue of how to design an eye-tracking experiment, and how to analyse the data. This book is a much needed comprehensive handbook of eye tracking methodology. It describes how to evaluate and acquire an eye-tracker, how to plan and design an eye tracking study, and how to record and analyse eye-movement data. Besides technical details and theory, the heart of this book revolves around practicality - how raw data samples are converted into fixations and saccades using event detection algorithms, how the different representations of eye movement data are calculated using AOIs, heat maps and scanpaths, and how all the measures of eye movements relate to these processes. Part I presents the technology and skills needed to perform high-quality research with eye-trackers. Part II covers the predominant methods applied to the data which eye-trackers record. These include the parsing of raw sample data into oculomotor events, and how to calculate other representations of eye movements such as heat maps and transition matrices. Part III gives a comprehensive outline of the measures which can be calculated using the events and representations described in Part II. This is a taxonomy of the measures available to eye-tracking researchers, sorted by type of movement of the eyes and type of analysis. For anyone in the sciences considering conducting research involving eye-tracking, this book will be an essential reference work.

In recent years, thanks to the development of eye-tracking technology, there has been a growing interest in monitoring and measuring these movements, with a view to understanding how we attend to and process the visual information around us. Eye tracking as a research tool is now more accessible than ever, and is growing in popularity amongst researchers from a whole host of different disciplines. Usability analysts, sports scientists, cognitive psychologists, reading researchers, psycholinguists, neurophysiologists, electrical engineers, and others all have a vested interest in eye tracking for different reasons. However, despite the scientific advancements and technological innovations resulting from recording eye movements, the growth of eye tracking also presents a variety of challenges-in particular how to design an eye-tracking experiment and analyse the data to fit your needs. This volume is a much needed comprehensive handbook of eye-tracking methodology. In its second edition, it describes how to evaluate and acquire an eye-tracker, how to plan and design an eye tracking study, and how to record and analyse eye-movement data. Besides technical details and theory, the heart of the book revolves around practicality-how raw data samples are converted into fixations and saccades using event detection algorithms, how the different representations of eye-movement data are calculated using Areas Of Interest (AOIs), heat maps and scanpaths, and how all the measures of eye movements relate to these processes. Part I presents the technology and skills needed to perform high-quality research with eye-trackers. Part II covers the predominant methods applied to the data which eye-trackers record. These include the parsing of raw sample data into oculomotor events, and how to calculate representations of eye movements such as transition matrices. Part III gives a comprehensive outline of the most common paradigms used with eye-trackers, and the measures which can be calculated using the events and representations described in Part II. This is a taxonomy of the measures available to eye-tracking researchers, sorted by type of movement of the eyes and type of analysis. With it, the time and effort to design your experiments can be much reduced. For anyone in the sciences considering conducting research involving eye tracking, this book is an essential reference.

Viele Frauen sind unglücklich mit einer hormonellen Empfängnisverhütung, kennen aber keine zuverlässige Alternative. Andere versuchen vergeblich, ein Baby zu bekommen und wollen ihre Fruchtbarkeit erhöhen. Wieder andere haben seltsame Symptome oder Schmerzen während ihres Zyklus. Ihnen allen bietet dieses Standardwerk zum Thema Fruchtbarkeit umfassende Informationen und Hilfe. Es beantwortet alle Fragen und liefert ein tiefes Verständnis für den weiblichen Körper. Bereits Hunderttausende Frauen haben mit Toni Weschlers Bewusster Fruchtbarkeitsmethode (BFM) erfolgreich auf natürliche Weise verhütet oder ihre Chancen auf eine Schwangerschaft maximiert. Diese Methode nimmt nur wenige Minuten am Tag in Anspruch und liefert einen kompletten Überblick über den Zeitpunkt des individuellen Eisprungs und der furchtbaren Tage einer Frau. Zudem bietet Weschler Tipps bei Endometriose oder Eierstockzysten, und zeigt, wie man auf natürlichem Wege seinen Hormonhaushalt ausbalanciert und seine Fruchtbarkeit auf lange Zeit erhält. Ergänzend zu den Informationen liefert sie eine Reihe Mustervorlagen für Tabellen zur Empfängnisverhütung, Kinderwunsch oder Menopause.

Eye tracking is a widely used research method, but there are many questions and misconceptions about how to effectively apply it. Eye Tracking the User Experience—the first how-to book about eye tracking for UX practitioners—offers step-by-step advice on how to plan, prepare, and conduct eye tracking studies; how to analyze and interpret eye movement data; and how to successfully communicate eye tracking findings.

Oliver B. Büttner untersucht, wie Methoden am Point of Sale sinnvoll eingesetzt werden können, um einkaufsbegleitende kognitive Prozesse von Ladenbesuchern zu analysieren. Der Fokus liegt dabei auf zwei Varianten zur Produktion von Gedankenprotokollen: dem Lauten Denken und der Videogestützten Gedankenrekonstruktion.

Dieses Handbuch bietet einen umfassenden Überblick über Methodologie, Forschungsdesigns sowie Erhebungsmethoden der standardisierten Kommunikationsforschung. Der erste Teil des Buches ist methodologischen Grundlagen gewidmet, die das Forschungsdesign und das generelle methodische Vorgehen betreffen. Die folgenden Teile nehmen jeweils eine der klassischen Erhebungsmethoden (Befragung, Inhaltsanalyse und Beobachtung) in den Fokus. In den einzelnen Beiträgen werden Grundprinzipien, kommunikationswissenschaftliche Anwendungsbereiche sowie aktuelle methodische und technische Varianten fundiert vorgestellt, diskutiert und evaluiert.
