The COVID-19 pandemic directly impacts educational systems worldwide. Although the online mode of education is the most viable solution under this scenario, it introduces new challenges to the course instructors. Primarily in the low and middle-economy countries, the majority of instructors do not have access to touch-enabled devices like tablets to mimic board-works, from where students can generate the class-notes. Pertaining to these constraints, in this paper, we propose an online note-generation system – Note-on-Watch, using community-off-the-shelf smartwatches and smartphones, leveraging the rapid and huge penetration of these devices across these countries. In Note-on-Watch, the instructor writes a text over a vertical board while wearing the smartwatch, and the locomotive data from the smartwatch is captured over a smartphone to regenerate the text to mimic on-device writing. We implement a prototype of Note-on-Watch using a Moto-360 smartwatch and Android smartphone and observe that the system nicely captures English alphanumerics and words.
