SUMMARY:Understanding the Context of Sit-Stand Desk Usage for Promoting He
 althy and Productive Behaviors
DESCRIPTION:Junghoon Chung and Sol Lim (Virginia Polytechnic Institute and
  State University), Donghan Hu (New York University), Daniel Vargas Diaz (
 ProjectUs.ai), and Sangwon Lee (Virginia Polytechnic Institute and State U
 niversity)\n\nUnderstanding the context of sit-stand desk usage is crucial
  for fostering healthier and more productive workplace behaviors. We condu
 cted a 15-day study involving ten graduate students engaged in desk-based 
 knowledge work, collecting comprehensive physical, work-related, and perso
 nal context data using desk height logs, screen activity tracking, and sel
 f-reported intention metrics. Our analysis revealed no significant differe
 nces in standing ratios across productive, neutral, and distracting work s
 tates, suggesting personal routines strongly influence posture choices. No
 tifications significantly increased standing durations without compromisin
 g productivity, demonstrating the effectiveness of timely prompts. Utilizi
 ng an XGBoost regression model, we successfully imputed sparse intention d
 ata with high reliability, highlighting physical and personal contexts as 
 key predictors. This research provides valuable insights and methodologies
  for developing intelligent, context-aware posture interventions. By integ
 rating quantitative findings with qualitative feedback, we offer a framewo
 rk for future ergonomic systems aimed at optimizing health benefits and wo
 rkplace productivity.\n\n
