Park, S.Y. (author), Lee, Rachel (author), Newton, C.E.L. (author), Han, Gisung (author)COVID-19 has made working from home routine for many. People who have had to maintain their productivity, particularly in physically and/or socially unacceptable home-working situations, experienced one of the pandemic’s disadvantages. The experience can vary substantially among individuals as well as by country. This study presents the results...journal article 2024

Balim, Haldun (author), Park, Seonwook (author), Wang, Xi (author), Zhang, X. (author), Hilliges, Otmar (author)Despite the recent development of learning-based gaze estimation methods, most methods require one or more eye or face region crops as inputs and produce a gaze direction vector as output. Cropping results in a higher resolution in the eye regions and having fewer confounding factors (such as clothing and hair) is believed to benefit the final...conference paper 2023

Park, S.Y. (author), Newton, C.E.L. (author), Lee, Rachel (author)The sudden adoption of working from home (WFH) during the COVID-19 pandemic has required the reconfiguration of home spaces to fit space for remote work into existing spaces already filled with other domestic functions. This resulted in blurring of home and work boundaries, the potential lack of space for telecommuting from home, and...journal article 2023
