Request to Take Part in a Research Study The purpose of this study is to understand commonly occurring situations that require intervention when users are engaged in a complex puzzle solving task. This phenomenon is similar to the situations users typically run into during the learning phase of a new software application. With this understanding, we hope to explore how to use machine learning algorithms to learn when to intervene. You will interact with a web-based simulator of the Rush Hour logic puzzle. You will be asked to solve a Rush Hour puzzle and provide your opinion about the puzzle solving experience. Your input will provide the researchers with important feedback for understanding software development with shorter learning curve. To participate please follow the steps below: (1) Copy and paste the URL https://aiplanning.cs.colostate.edu:9080/ on a web browser (e.g., Chrome, Firefox). DO NOT click the link. COPY and PASTE (2) Read the consent agreement and click the 'Agree' button to continue the study. You may exit from the study by clicking 'I do not Agree' button. (3) Once you agree to participate in the study, a short tutorial is available on the web page to help you get started in the tab Learn. (4) Click on the Play tab to start the puzzle solving task (5) When the puzzle solving task is done, complete the Demographic survey questionnaire by clicking on Take a Survey tab. There is no time restriction for solving the puzzle, but it should take no more than 10 minutes to complete the session. Your participation is voluntary and there will NOT be any payments. Please contact Sachini (sachini@cs.colostate.edu) if there are any issues using the web application or if you have any further questions. Thank you for your participation Prof. Darrell Whitley Sachini Weerawardhana Computer Science Department
