Dear CCE students, We are currently recruiting participants for a mixed-reality sloped roof experiment on workers’ balance under human–drone interaction. In this study, you will be asked to perform a shingle installation task while wearing an MR headset and other wearable sensors. The roof setup includes a slight incline to simulate real-world conditions. The entire experiment will be completed within 1.5 hours, and the location is at Herrick Lab. Due to the size limitations of the wearable sensors, we are primarily recruiting Male students for this study. If you have a history of cybersickness or are prone to VR-related discomfort, please kindly inform us in advance. After finishing the experiment, you can get a $25-30 gift card and a certificate of participation in an NSF-funded project. If you are interested, please scan the QR code to sign up. [cid:934771f5-e27b-4fb9-94f5-a6a7306a840b] If you need more information, feel free to ask me. Thank you so much for your time and consideration! * Experimenter: Yibo Qiang * Email: ybqiang@purdue.edu Warmest regards, Yibo Qiang
