This work explores how physical exertion can influence handwriting and drawing quality. We collected data from 17 participants and used machine learning to predict perceived exertion based on simple line drawings. Our findings suggest that interactive systems could use these insights to assist users when they experience discomfort during physical activity, although more research is needed for more complex drawings and handwriting.

Mid-air gestures in Augmented Reality (AR) often cause discomfort during extended use due to the "gorilla arm" effect. While previous research has focused on simple interactions like pointing or button presses, this paper examines the ergonomics of more complex tasks, such as rotational gestures. We present findings from a controlled experiment exploring the impact of rotational tasks on user comfort within arm's reach. These insights pave the way for designing more ergonomic mid-air gesture modalities for future AR applications.
