A Comprehensive Guide to Empirical Research Methods for Human-Computer Interaction

Q: How can empirical research methods in HCI be adapted to study emerging technologies like augmented reality and brain-computer interfaces?

To adapt empirical research methods in HCI for studying emerging technologies like augmented reality (AR) and brain-computer interfaces (BCI), researchers can incorporate specialized tools and techniques tailored to these technologies. For AR, researchers can utilize eye-tracking devices to analyze user gaze patterns and interactions within AR environments. Conducting user studies in real-world AR settings can provide valuable insights into user behavior and preferences. In the case of BCI, researchers can employ neuroimaging techniques such as EEG to measure brain activity during interaction with BCI systems. This data can help evaluate cognitive workload, user engagement, and overall usability of BCI devices. Additionally, researchers can explore innovative experimental designs that account for the unique characteristics and challenges posed by AR and BCI technologies.

Q: What are some potential limitations or biases that can arise in HCI experiments, and how can researchers address them?

Several limitations and biases can arise in HCI experiments, impacting the validity and reliability of research findings. Common issues include selection bias, where participants may not represent the target user population accurately, leading to skewed results. To address this, researchers can use random sampling techniques and ensure diverse participant recruitment to enhance the generalizability of findings. Another challenge is experimenter bias, where researchers' expectations or behavior influence participant responses. Researchers can mitigate this by implementing double-blind study designs and using standardized protocols to minimize subjective influences. Additionally, social desirability bias, where participants provide socially acceptable responses, can be addressed by ensuring anonymity and confidentiality in data collection.

Q: What role do qualitative research methods play in complementing the quantitative approach covered in this course, and how can they be effectively combined?

Qualitative research methods play a crucial role in complementing the quantitative approach in HCI by providing in-depth insights into user experiences, motivations, and perceptions that quantitative data alone may not capture. Qualitative methods such as interviews, observations, and think-aloud protocols can help researchers understand the context, emotions, and subjective aspects of user interactions with technology. By combining qualitative and quantitative approaches, researchers can gain a comprehensive understanding of user behavior and preferences. Triangulation, a method that involves integrating findings from both qualitative and quantitative data sources, can enhance the validity and reliability of research outcomes. Researchers can use mixed-methods designs to leverage the strengths of each approach and provide a more holistic view of the research problem.

核心概念

This course provides a comprehensive tutorial on designing and conducting empirical research studies in human-computer interaction, as well as techniques for writing successful CHI conference papers.

摘要

This course covers key topics in empirical research methods for human-computer interaction (HCI). The first session focuses on:

Understanding the scientific method and what constitutes empirical research
Formulating testable research questions
Designing experiments to answer research questions
Key components of an experiment (independent/dependent variables, counterbalancing, ethics approval, etc.)
Hands-on participation in a real experiment as both a participant and an investigator

The second session builds on the first by:

Discussing the results and analysis of the in-class experiment
Exploring experiment design issues like within-subjects vs. between-subjects factors, internal/external validity, and counterbalancing
Covering data analysis techniques like main effects, interaction effects, and establishing cause-and-effect relationships
Providing guidance on organizing and writing a successful CHI conference paper

The course is designed to benefit anyone interested in conducting user studies or writing HCI research papers, requiring only a general background in HCI. It provides an end-to-end tutorial on the empirical research process in HCI.
