2016 / LINE / Product Designer

Letter is a side project of mine mainly designed for users who prefer a slow communication instead of using instant messages. Instant messages can be overwhelming filling our lock screens with seemingly-endless notifications. Letter, on the other hand, represents a new & slower way to communicate.


I could easily recall the days when I didn’t want to reply to any messages myself. I also conducted casual research on how users deal with smartphone notifications. Interestingly, I found out that some people were going on “Digital Detox,” which refers to a state where a person voluntarily refrains from using digital devices such as smartphones or computers and social media platforms.




Letter won the second prize for the internal-hackathon, but after a thorough investigation, it was decided not to be turned into a real project due to a Canivalization Issue. Instead, some of its features were transferred into LINE Lite Project, which is a lighter version of LINE for an emerging market.
