Many researchers have started to explore natural interaction scenarios for children. No matter if these children are normally developing or have special needs, evaluating Child-Robot Interaction (CRI) is a challenge. To find methods that work well and provide reliable data is difficult, for example because commonly used methods such as questionnaires do not work well particularly with younger children. Previous research has shown that children need support in expressing how they feel about technology. Given this, researchers often choose time-consuming behavioral measures from observations to evaluate CRI. However, these are not necessarily comparable between studies and robots. This workshop aims to bring together researchers from different disciplines to share their experiences on these aspects. The main topics are methods to evaluate child-robot interaction design, methods to evaluate socially assistive child-robot interaction, and multi-modal evaluation of child-robot interaction. Connected questions that we would like to tackle are for example:

1) What are reliable metrics in CRI?

2) How can we overcome the pitfalls of survey methods in CRI?

3) How can we integrate qualitative approaches in CRI?

4) What are the best practices for in the wild studies with children?

TOPICS

Submissions will be selected on the relevance of the contribution in regard to the potential to generate interesting discussion at the workshop. The goal of the workshop is to discuss advantages and short-comings of using different evaluation methods in order to compile guidelines for future CRI research. Therefore, in the papers, the authors should reflect on the following aspects:

• Details about the project(s)that the authors work on, like: what robots do the authors work with? How old are the children did the authors work with? Do the authors work focus on typically developing or non typically developing children? What is the goal of the project?;
• Methods that the authors use, like:qualitative or quantitative;
• Metrics, tools, toolkitsthat the authors use;
• Best practices;
• Challengesthat the authors face when using these methods;
• Solutionsdeveloped to address these challenges;

TOPICS INCLUDE, BUT ARE NOT LIMITED TO:

• Evaluating child-robot interaction in education
• Evaluating child-robot interaction focusing on cognitive development
• Long-term evaluation of child-robot interaction
• Non-typically developing child-robot interaction evaluation (e.g., ASD)
• Evaluating socially assistive robots for children
• Multiparty child-robot interaction evaluation
• Child-robot engagement evaluation
